BUGATTI CHIRON INSIDE THE FACTORY FULL MANUFACTURING

 BUGATTI CHIRON

it's the fastest most extreme and most exclusive production super sports car in the world the French made vehicle shoots along the road at a top speed of 420 kilometers an hour this hyper car scratches at the boundaries of physics a motorized superlative it is this ambivalence between beauty and beast to awaken the beast in this ultra powerful engineering work of art the developers have made the best even better I think you start working where others have stopped the mission a hyper sports car with 1500 horsepower and a top speed of 420 kilometers an hour that the whole world said you'll never manage to cram so much power in a car the whole world was wrong but the enormous power concealed in this rocket poses new challenges you have to be sure that you've still got enough white on the front that it won't take off to ensure a healthy body mass index the Alsace engineers have fitted the all-wheel drive vehicle with lots of carbon titanium and magnesium potential lots of things you would normally only find in Formula one cars and the elegant top athlete with the 16 cylinder engine is anything but normal the design engineers all agree about that but my nature can you compare the sheer on with another vehicle no God created heaven and earth and the French created the bugatti shear on the spearhead of vehicle construction is located in multi france the bugatti hyper sports car manufacturer these record-holding dream cars have been built on the site of the former family estate for the past 110 years built in 2004 in the form of a company logo the Alsatians lovingly refer to the new production building as the Dream Factory inside 20 employees assemble up to 16 vehicles at the same time at 12 stations with these production figures Bugatti is part of the ort Keturah among vehicle manufacturers the bugatti chiron is the flagship of the current collection it's a lot of manual work it's like in a Formula One racing stable everything's handmade at various stations yeah I some 300 people work at Bugatti engineers sales representatives and purchasers I encode for people who share a passion us to develop build and sell super sports cars weekend Subhan once offical fini it takes two months until the French have assembled around 2,600 individual parts to form a new motorsport work of art the Sheeran's hood conceals pure performance the world's most powerful production engine has 16 cylinders and a displacement of 8 litres this enables the Bugatti to reach its record-breaking speed of 420 kilometers an hour for offset operating turbochargers accelerate the 1500 horsepower projectile from zero to a hundred kilometers an hour in just 2.4 seconds instead of a classic production line there are four special stations in Molsheim they each contain two independent lifting platforms because the sports coupe a is made up of two parts which the employees marry with one another during production three mechanics always assemble what is called the Sheeran's rolling chassis strictly by hand the drivable naked vehicle skeleton an expensive delivery is waiting at the Bugatti cargo ramp this body component heralds the construction of a new all-wheel-drive behemoth the monocoque is a hollow driver cockpit and is made entirely of carbon fiber reinforced plastic or CFRP for steel journals now rise up out of the gleaming shop floor two workers install an assembly platform on them the production crew then heaves the 150 kilogram carbon framework onto the platform each material that the bugatti design engineers install fulfils a specific purpose the materials we use at Bugatti are the finest but also the lightest available we used lots of magnesium titanium carbon and aluminum lots of things that you would normally only find in Formula one cars don't I think there are no miracles and Technology our bugatti chiron is capable of topping 400 kilometres per hour and can accelerate from zero to 100 in less than three seconds we're talking about numbers and performance that are somehow unreal means that this simply represents a lot of work at the development and also at the production level to ensure this performance is always achieved the technicians install the wiring harness inside the carbon cockpit the harness consists of 2.5 kilometres of cables and is the nerve system of the shiron it connects the vehicles 20 control units the mechanics fastened the electrical wires to the monocoque with titanium screws like all of the other elements in this racing machine the wiring harness is also designed as compact and light as possible the rear frame of the exclusive kupe is assembled on the second platform but first the workers move the assembly frame to the heart of the bugatti the 640 kilograms 16 cylinder engine due to the size and the enormous weight of this unit the assembly platform comes to the engine in Molsheim the mechanics use a crane to put the german-built high-performance powerplant down on the assembly platform the engines are manufactured at the Volkswagen engine plant in SATs katha covering 2.8 million square meters this site boasts its own bugatti department whoever works here belongs to the absolute elite among engine mechanics as the 16 cylinder is considered to be the holy grail of engines two technicians need one week to build one of the 1500 horsepower quad turbo engines your mock we built a car that does over 400 kilometres an hour and drives elegantly to the Opera in the evenings to do this you need not only a car that can achieve this but also an engine that's capable of driving in the summer and winter in cities traffic jams as well as on racetracks and that's something of a challenge for the Formula One teams are good at building racing engines with lots of power and Volkswagen is adept at building good engines for the road for a golf but this combination of two worlds is Bugatti specialty christened production nests by the technicians the four workplaces in the engine department are also special each station is structured so that a complete unit can be built here the experts manufacture a total of three of these powerful heavy weights per week to make the engine as compact as possible eight cylinders are distributed over each of the two v-shaped banks thus creating an artificial W engine with 16 cylinders the W 16 achieves its maximum acceleration with for high-performance turbochargers via turbine the quartet compresses the air in taken at the front of the vehicle and presses it into the combustion chamber in stages thanks to what Bugatti calls sequential turbo charging turbo 3 and 4 cut in at 2,800 rpm this prevents turbo lag and therefore ensures constant power at production nest to a new crankcase is ready to be assembled a mechanic has just installed the Pistons in the 16 cylinders and connected them to the crankshaft before the engine builders continue their work they use an electronic torque wrench to simulate engine operation for instance this allows the workers to check that the piston stroke does not lead to friction on the cylinder wall otherwise serious engine damage called piston seizure could occur later while driving the Sheeran's engine is made up of around 3,700 individual parts the technicians pre-assemble individual components at workplaces next to the assembly stand this worker is assembling various engine elements here he is fitting a fuel pump later on it will deliver the required quantity of fuel to the engine the worker then installs the alternator its task is to generate electricity for the starter battery and other electrical components at the same time his colleague prepares the oil pan for assembly it has to be absolutely leak tight because later on the pan contains the engine oil needed to lubricate the 16 cylinder engine this is why the technician now takes it to an automatic station two different processes take place here first a special oxygen plasma cleans the surface of the pan although the engineers pay strict attention to cleanliness there is still a fine layer of dirt on the components the station then applies a black sealant onto the edge of the magnesium pan once the sealant has been completely distributed the technician has 20 minutes to assemble the component to do this he positions the oil pan over the crankshaft onto the lower side of the engine block and seals it only specially trained technicians are permitted to build the Sheerin engine whoever has successfully completed the additional two-year training can justifiably feel proud I'm one of a total of eight technicians worldwide who are permitted to build this engine in series of course that makes you very proud it's like you made your hobby your vocation you can already get a sense of the enormous dimensions of the combustion engine at station 3 the quad turbo engine draws its power from the ignition of a fuel air mixture these camshafts ensure the correct mixing ratio driven by the engines chain the cams rotate around their metal shaft and thereby press alternately on the valves of the individual cylinder heads this enables them to open and close in a specific stroke the mechanics bolt two of these 1 kilogram engine components per cylinder Bank the w16 engine in the Sheeran has a total of four camshafts so that the mixture can ignite the engineers now insert sixteen spark plugs into the cylinders they supply the final pulse for starting the engine they also influence the four-stroke engines performance consumption and pollutant emissions the plugs generate a powerful spark between 500 and 3500 times a minute the resulting explosions set the ranks of pistons in the cylinder bank in motion the stripped engine meaning all of the components needed to operate the drive unit is now complete however the massive power plant is considerably bigger when fully assembled all further attaching parts are true to the Bugatti philosophy of more power and maximum performance the final dimensions of the engine in a Sheeran are four times those of a standard passenger car engine since 2005 the engines for the French luxury brand have been hand-built at the plant in Zod's katha even when the company was founded in 1909 the engine blocks were cast by hand at Bugatti back then the engines for the first models were produced at the plant premises in Molsheim although working conditions 110 years ago were certainly tougher the basic structure of high-performance engines has barely changed with his racing and luxury cars the Milan born company founder was considered to be a legend of European automobile history even back then at eight order Bugatti developed and built vehicles that are still icons of motoring history today cars like the t35 with the bugatti atlantic ettore bugatti was a perfectionist and did incredible things here in this plant back in the 20s and 30s the simple fact that we call our plant an atelier rather than a factory is quite a statement in itself the entire mole time site here in Alsace France is unique for an automotive manufacturer because it exudes pure history and no other manufacturer can offer that the name Bugatti stood for revolutionary ideas from the get-go in 1933 the Milan born visionary even built a rail bus with a top speed of 200 kilometers an hour a tour day was often laughed at for his unconventional ideas but in the 1920s Bugatti super sports cars achieved worldwide fame thanks above all to their record number of 2000 race victories the name Sheeran also played a role back then cheval sharone was a racing driver in the 1920s a very successful one we won a lot of races with him buddies today the bugatti chiron named after him as the ultimate hyper sports car and the engine is at the heart of it an eight liter engine with 16 cylinders and up to 1600 horsepower however the objective of building the world's fastest production sports car in the form of the new Sheeran was viewed very critically by the industry gun severity the whole world said you'll never manage to cram so much power in a car but a displacement of 8 liters over a thousand horsepower as a conventional task you had turbochargers to it at some point you achieve that power and then you're faced with a big problem you can't find a test bench anywhere in the world that can cope with this power but the engineers solved precisely this problem on an internally developed test and they put the eight liter engine through its paces until the manifold glows once completed the engineers test the power output and above all the durability of each power plant behind the roughly 30 centimeter thick safety walls of the test booth the team has strapped the combustion engine down and coupled it to a dynamometer it's able to demand the engines full output of 1500 horsepower at 6700 revolutions per minute the stress applied on the test bench is significantly higher than during vehicle operation an engine is tortured for up to 1,000 hours on the test bench the sin fee that's hundreds of thousands of kilometers on the road and what if an engine has survived that can survive anything a gigantic blower cools the engine during the test special sensors measure a total of five hundred different values which the testers check on the monitor the tests were also an important part of developing the 16 cylinder engine because the results were incorporated into its 3d model and helped the design engineers to detect possible critical areas it took three years to develop the Sheeran's power plant often optimization requirements also arise due to legal specifications corresponding measures that the engineers plan on their screens then have to be verified on the real component during a special auditory test an acoustic engineer checks whether the exhaust system simulation matches reality to do this the sound expert applies a pure tone to the exhaust tailpipes using a loudspeaker the sound causes the air particles inside the system to vibrate the engineer records the resonance using a microphone this allows the sound and the volume to be viewed on the monitor by 2026 passenger car driving noises have to be reduced to 68 decibels that's roughly the same as a television at low volume at the same time however the engine sound must not suffer the acoustic factors are particularly crucial to the experience of driving the Sheeran that's what the drivers hearing is an entirely unconscious process it's nevertheless he needs specific information he wants to know when the road changes he wants to know whether the engine rpm is too low or too high he wants to know what the absolute vehicle speed is because via the wind noises if any of this information is missing the vehicle is perceived as unharmonious [Music] does her galoshes cliff the rolling noise is relevant how the windows are constructed how well the chassis is insulated from the cockpit just because all of this characterizes the overall noise perceived by the driver this all has to be composed to form a consistent concert to achieve a positive experience in the vehicles interior and who better to test this experience in new models than a genuine motor racing expert the former LeMond winner Andy Wallace is Bugattis test driver he has already driven around 100,000 kilometers in the luxury sports car from multi I'm an absolute dream job the Briton also provides the developers with direct feedback about the Sheeran's performance and handling from the driver's cockpit if he like cars and you you can maybe dream about supercars this one is the top the very top of the pile  and for me to be able to drive this car every day if you told me that when I was seven years old I never would have believed you so for me it's fantastic however Wallace will be thinking about the following drive for a long time to come with this sheer on the Britain will set a new speed record of three hundred and four point seven seven three miles an hour or four hundred and ninety point four eight four kilometers an hour the Sheeran's Super Sport 300 plus pre-production model offers an additional 100 horsepower totaling 1600 horsepower on the test track in ela lesson Germany its tires will be rotating no fewer than 4,000 100 times per minute this would be the first time in history that a production vehicle breaks the 300 mile an hour barrier and off he goes Andy Wallace floors the accelerator and is already doing 100 kilometres an hour two seconds later covering around 11 square kilometers the test site lies at the center of a pine forest curves and straights follow in quick succession this makes it difficult to keep the vehicle on track you're constantly turning to go straight and this is at the same time that you're traveling 136 meters per second everything's coming at you really really quick so the sense is coming in - you are crazy and you have to try and keep all that under control and then it's not something you do every day so it's not something you can practice you just end up doing it and it's um it's pretty impressive 3.5 kilometers ahead of the record the Sheeran is still picking up speed the down thrust also called downforce on its rear end increases this causes the front end to lift the Bugatti uses a complicated aerodynamics concept to counteract the principle that helps airplanes to take off after 70 seconds at full throttle Wallis breaks the record Wow guys what a fantastic car thank you should fancy a messy I can't thank you enough in the Atelier in Molsheim France a worker transports an important component to a newly arrived engine block two mechanics now coupled this seven-speed direct-shift transmission to the powerplant the automatic shift unit ensures constant power output when shifting gears because one clutch closes at the same time as the other is opening the automatic transmission ensures consistent tractive force the workers then take the new drive unit to an assembly station covering 1,000 square meters the shop is more akin to a sterile operating room than a vehicle workshop there are no oil stains or rubber abrasion from car tires on the highly polished synthetic resin floor the two-seaters engine alone cost around 300 thousand euros over the next few hours the rear section of the vehicle will be built around the high performance unit to do this the Bugatti surgeons first attached the chassis to the side sections of the body alongside the lifting platform they are also made entirely of carbon a technician first bolts the independent wheel suspension elements to the carbon fiber framework the hypercar has no rigid axle this means that each wheel can be actuated individually and therefore has maximum grip or contact surface on the asphalt as a result the two-ton Bugatti remains stable even when taking tight corners on a wet road surface depending on the driving situation the on-board computer regulates the four wheels tow and camber to ensure this the entire substructure of the extreme sports car is adaptive these suspension struts that the technician is installing can also be optionally set to a family car or racing car profile the hardness of the damper called its characteristic and technician jargon is adjusted by allowing more or less oil to flow from one shock absorber tube to the other [Music] the worker now mounts the finished side section on the engine block with his colleague building a new hyper car in the exclusive French manufactory is complicated and involves 2590 individual steps good timing in the production sequence is absolutely crucial I'm apologizing we always assemble sixteen vehicles at the same time using twenty employees these includes seven mechanics for coachbuilders three technicians you assemble the vehicle interior two painters and for electricians don't gloss on without this team of twenty persons assembles the vehicle in eight weeks visa man this needs to be well organized to avoid delays and ensure that the customers are satisfied yeah next the supercar is fitted with its exhaust system when the engine is running temperatures as high as 500 degrees can be reached at the rear muffler that's why this employee first installs a galvanized heat shield on the exhaust pipes his colleague carries the gigantic exhaust to the chassis later on six tailpipes rid the Sheerin of everything the eight liter powerplant spits out of its 16 cylinders the team now fastens the enormous titanium muffler to the rear end of the emerging Bugatti titanium is light ductile and particularly heat resistant this is important so that the material does not crack under the extreme heat the crew then clads the mid engine with further elements to protect it on all sides tons of them too we've now fitted all the parts around the engine and once we've assembled bolted and connected everything we can connect it to the front section to the monocoque this is what distinguishes us from classic mechanics and garage this really is assembly we start with nothing and build the vehicle and that is the difference between this and other vehicles because this is an exclusive card extremely powerful vehicles you have to work very precisely you can't afford to make mistakes it's now becoming cramped in the monocoque - such a cockpit framework contains a total of 320 square meters of carbon placed end to end all of the individual carbon fibers are 9 times the distance from the earth to the moon a mechanic is now fitting one of the Sheeran's two differentials on the underbody of the chassis element a computer tells him whether he has tightened all of the bolts to the correct torque and stores his production data in the system the differential compensates the differences in wheel speeds when cornering the wheels on the inner side of a corner cover a shorter distance than the outer wheels and therefore turned more slowly conversely this means that the outer wheels require more power to cover the greater distance in the same time a transmission inside the differential distributes the engines power to the hypercars individual wheels to varying degrees bringing the vehicle to a stop from its top speed of 420 kilometers an hour poses a major challenge for the brake system the temperature can soar to 1,100 degrees when the supercar is braked that's as hot as glowing lava the men in the Atelier therefore also fit a heat shield on the wheel suspension before installing the carbon ceramic brake discs one of the sport brake discs weighs around eight point five kilograms its caliper is the world's largest 3d printed titanium part the Sheerin currently has the most powerful brakes of any production vehicle worldwide but this is not enough for the French 1/2 here a design model of a brake saddle that we don't have in production yet but we're testing it where you see material on this part that's where the the load path is happening and that's where the the strength needs to be on this building part and where there is no material at all there's also no load on the part that means you can save that weight it doesn't need any styling lines but just the pure genius of the technical development is aesthetically so interesting and so intriguing that you leave well enough alone and apply it to the car and this is really fascinating in itself the bugatti crew assembles the front of the monocoque this worker is fitting a guard for the Sheeran's sensitive electronics and mounting a control unit for controlling the vehicle dynamics later on this so-called ESC helps the driver to keep the hypercar under control by specifically breaking individual wheels for instance the system prevents the vehicle from skidding when cornering at high speed over a period of four days the team has installed 2600 components at the special stations an important ceremony is now on the agenda for the front and rear frames like everything at Bugatti the marriage of the monocoque and the rear section in the mall team luxury Atelier is something special the crew first moves the platform's to the same height the frame sections have to fit precisely in one another in the worst case the construction would have to be taken apart again to adjust individual elements the three men now maneuver the 750 kilogram rear section to the monocoque the iron wave accompanies the rear section to its better half the team gathers its strength again for the last few centimetres the fact that the Sheeran's chassis consists of two parts offers several advantages so that the driver's cockpit is subsequently stable and therefore as safe as possible the front section is made completely of carbon however the entire body is too big to be built entirely of this lightweight material the vehicle is also designed so that the rear end can tear off in the event of an accident because if the engine catches fire things quickly become dangerous a total of fourteen titanium bolts that the technicians are now fastening ensure that the front and rear sections are joined firmly together on the underbody to Bugatti mechanics now fasten the lines for the luxury cars operating fluids later on engine and transmission oil as well as brake fluid will flow through them the Sheeran's fuel hoses are made of tough polyamide plastic the air stream at the front end of the vehicle ends up in these two carbon chambers via special filters it flows into the four turbochargers compressors where it is then forced into the cylinders and increased pressure this means that there is more air and therefore more oxygen for combusting the fuel the result is a more powerful explosion higher pressure and thus linear engine power output the Bugatti special tires are custom products from Michelin with a width of around 36 centimeters the tires have to withstand enormous forces during vehicle operation at maximum speed the wheels rotate around 50 times per second this means that 7 metric tonnes are pulling on their tread that tortures the tough rubber the Sheerin is fitted with semi slicks they have a lower tread depth and therefore less weight as a result the tires offer plenty of grip despite the enormous centrifugal forces a set of the semi slicks costs nine thousand two hundred and fifty euros the hyper car is now filled with its operating fluids an employee feeds the vehicle with engine oil brake fluid and 40 litres of water when the car is driving this is circulated 20 times per minute by the pump to prevent the engine and powertrain from overheating the mechanic then fills the hypercars tank the fuel tank can hold 100 litres of gasoline the shiron consumes an average of 20 2.5 litres every 100 kilometers the Bugattis rolling chassis now proceeds to its first test station in the Antilles annex the French had to develop a new dynamometer for the sheeran which is capable of withstanding the hypercars 1,500 horsepower this means that the bugatti dynamometer is also the most powerful of its kind in the world the technician first attaches the two-ton vehicle to these wheel clamps the safety flap of the acceleration roller then drops down and the ventilation system shafts rise up then he fastens a fresh air hose to the front of the chassis so that he doesn't suffocate in the cockpit his colleagues have provisionally fitted a windshield in the luxury car the technician now also fits two doors to establish the most realistic conditions possible in the vehicle interior now the high performance car can show what it's made of for the first time the employee accelerates up to 200 kilometres an hour the sports car has to complete a total of 342 tests he tests the engine the transmission and all vehicle dynamics programs for 3 hours the bugatti covers around 60 kilometers on the dynamometer this Sheeran has passed all of the tests the employee releases the vehicle from the wheel clamps and removes the doors his colleague now takes this superlative on wheels to the next station here the Sheeran is dressed in its Sunday best to do this the exterior crew pre assembles the body parts next to the lifting columns and cleans and polishes them the individual elements are large and fragile that makes this work step extremely demanding we get parts that are perfectly painted and absolutely flawless a pesky can be what is then complicated for us is to install these parts without damaging them that's not easy we have to take great care work very precisely and attach the part so that everything is perfect for the final quality check and the customers ultimately satisfied it takes up to four days to clothe the vehicle installing the windshield is particularly complicated it has to be positioned exactly and be absolutely watertight to install the windshield the technicians first coat the body with a primer they apply a special adhesive onto the safety glass the workers then place the windshield onto the vehicle frame using a vacuum lifter the two component mixture reacts to form a particularly elastic resin and ensures that the glass can withstand even strong vibrations each Sheerin is a unique work of art and can be completely individualized the choice of material and color combinations for styling the vehicle is virtually unlimited Ettore Bugatti himself once said perfection is never achieved but to this very day designers have been attempting to create the most perfect models with a mixture of unbridled power technical beauty and flawless elegance to accomplish this they work closely with the developers because the paramount objective of motorsport artists is form follows performance the striking see of the Bugatti DNA on both of the Sheeran's flanks therefore also serves a specific purpose to a lot of people that line looks like a stylistic idea of a designer or because it looks so nice and romantic let's just do it like that it's exactly the opposite the performance need from the engineer was as much air intake along the whole body side of the car was needed to feed all that pressured air into the engine compartment for cooling purposes and for me that is always the most authentic way as a car designer that I can answer the need of a technical problem with a stylistic combination Bugattis vehicle DNA has constantly evolved according to this principle due to its shape the exclusive Koopas extraordinary radiator grille has been nicknamed the horseshoe in 1910 however the first Bugatti model the type 13 had an egg-shaped front end to improve the vehicles aerodynamics and cool the increasingly larger engine the designers adapted the look of the grille to the technical requirements probably the only part of a bugatti whose shape or weight has not been optimized is the brand logo this sheer on in the Atelier in mall time is now almost fully dressed each paneling element also plays a role in the complex aerodynamics this consists of active and passive systems all of the components integrated into the paneling are passive the active modules can be actuated and adjusted to the position and speed of the vehicle the super sports car is a master of aerodynamics the air curtains at the front specifically guide the impacting air pressure through and past the vehicle this presses the Sheerin onto the asphalt and cools the brakes [Music] the 1.5 meter wide rear spoiler adapts fully automatically to the respective driving situation 0.8 seconds after applying the brakes the adaptive wing tilts to an angle of 49 degrees thus acting as an extremely effective air brake to decelerate the Bugatti the hydraulic spoiler is the last of a total of 55 panel parts that the mechanics fit onto the luxury car we regulate the angular position of the rear wing the diffuser flaps in the underbody via the speed range this is how we ensure that the vehicle is safe in every driving situation and that the focus is on straight-line stability or agility in 2017 the airbrake played an important role in another world record formula one winner juan pablo montoya accelerated the Sheerin to four hundred kilometers an hour from a standing start after 700 meters he was already doing over 300 kilometres an hour in the 33rd second the Colombian racing driver reached the 400 kilometer an hour mark he brought the two-ton vehicle to a standstill again after 491 meters in just nine point three seconds by fully applying the brakes Montoya took exactly 41.96 seconds and covered a distance of 3.1 kilometers to accelerate the Sheerin up to its top speed and break it that was a new world record so far no other vehicle has managed to achieve this outstanding performance a force of 850 kilograms presses on the rear wing during maximum braking from top speed this brings the hypercars rear axle to its knees during this sharp breaking maneuver forces of around 2g act on the vehicle and the driver a further shiron has now been fully assembled at the Bugatti premises in multi France so that it's not scratched during its first test-drive the employee is covering each millimeter of the hyper sports car with a protective film covering the paneling takes around four hours this supercar has been fully covered later on it will demonstrate what it's capable of each Sheeran has to complete a test-drive of around 350 kilometers before being delivered we do the test drives with a protective film in the car on the windshield it takes half a day to cover the sharone with film but it's up to us not to damage the car under any circumstances we want to deliver a perfect vehicle over these 350 kilometers we simulate all the driving situations that the customer might encounter villages country roads mountains freeways and of course we have rented the airfield in Colmar to test everything that's not allowed on public roads only then can the customers safely drive the vehicle at its top speed of 400 km/h so that he can do that the quality tester now climbs into the driver's seat for around 5 hours the cockpit is also fitted with protective covers the tester additionally wears gloves so that no marks are left on the sports steering wheel the tester tests different factors such as performance the individual drive programs and the background noise in the interior of the Sheeran before leather seats so much as squeaks when cornering the test driver notes this defect in his log the tester then turns onto an airfield here he immediately takes the Sheerin up to its limits he communicates with the tower crew by radio because air traffic is still operating and that can quickly become hazardous the stormy weather also makes conditions more difficult the test driver quickly drives up to the start of the 1.6 kilometer long takeoff runway then he's given the green light from the tower the expert hits the accelerator he accelerates the hypercar up to 300 kilometres an hour in around 13 seconds however the primary objective is not to test the top speed but to get the shear on to develop its full output of 1500 horsepower due to safety reasons the sports car is governed to 380 kilometres an hour this special key can be used to accelerate it a further 40 kilometres an hour as soon as the high speed key is engaged on the left of the driver's seat the vehicle checks all of its systems fully automatically because at over 400 kilometres an hour any defect can immediately prove to be fatal the shear on is wonderful to drive it is incredibly stable when you switch from left to right its chassis is also fantastic in response to any road conditions like a dream as if you were skiing after the stress tests the shear on is taken to the company's own washing facility the hypercar can only be delivered to its new owner when it's absolutely spotless bugatti the french sports car menufactory is an absolute superlative at 12 high-end production stations in mul time 20 elite mechanics produce the fastest most exquisite and most extreme hyper cars in the world with multiple world records the french extremists have proved and if it's comparable if it's no longer bugatti after even more than 110 years of vehicle production nothing about this philosophy has changed.
