World record for the Bugatti Chiron1: the 1,500 PS super car from Alsace has accelerated from a standing start to four hundred km/h and braked back to a standstill in just 42 seconds (41.96). This is the fastest time ever reached and officially measured for this driving manoeuvre for a production vehicle throughout the world. The run was supervised and officially certified by SGS-TÜV Saar, part of SGS, the world leader in inspection, testing, verification and certification. The Chiron completed the manoeuvre in a distance of only 3.112 kilometres. This underscores the supercar’s unique position in the extreme performance range. The world record was set by Juan Pablo Montoya, winner of the Formula 1 Monaco Grand Prix, two-time winner of the Indy 500 and three-time winner of the 24 hours of Daytona. The 0-400-0 manoeuvre is the first step on the way to a new world speed record for production vehicles which Bugatti intends to set in 2018 and a further highlight in the success story of the Chiron, which made its world debut last year. 300 of these exceptional super sports cars, which are being produced in a limited series of 500 vehicles, have already been sold. Bugatti is presenting the 0-400-0 world record Chiron at the 67th International Motor Show (IAA) which is being held in Frankfurt from 14 to 24 September 2017. The Bugatti stand is located in Hall 3.

HOW TO BUILD A £2million Bugatti Chiron


A weekend in August 2017. It is dry and sunny and the wind conditions are calm. The Chiron rolls up to the start with racing driver Juan Pablo Montoya at the wheel. He has a long straight ahead of him. Using the Top Speed Key which is typical of Bugatti, he activates the Top Speed mode, which allows a Chiron to drive faster than 380 km/h. A signal is heard. He places his left foot firmly on the brake pedal. Montoya engages first gear and then activates the Launch Control. The digital display beside the speedometer acknowledges the command received and the 1,500 horses wake up. On your marks! Full concentration for the driver and team. Bugatti invited Montoya to complete the 0-400-0 km/h manoeuvre under real-life conditions to underpin the exceptional position of the Chiron in terms of braking and acceleration. He accepted, eager to meet Bugatti and the Chiron.

Montoya presses the accelerator to the limit with his right foot. The 8 litre W16 engine runs up to 2,800 rpm. The powerful turbochargers speed up and there is no doubt that this car is straining at the leash. Get set! Montoya releases the brake pedal. Go! The four wheels of the Chiron receive equal power and grip the tarmac with full force. The car shoots forward, developing maximum torque. The traction control prevents the wheels from spinning. In combination with ESC (Electronic Stability Control), it catapults the Chiron forward, keeping it firmly on track. Full acceleration. The time is running. The world flies past.

The incredible acceleration of the Chiron, its absolutely linear power curve and the enormous torque especially in the low engine speed range are the result of the two-stage turbocharging system developed by Bugatti especially for this vehicle. This is one of the outstanding technical features of the Chiron powertrain. To ensure maximum acceleration from a standing start without any “turbo lag”, the Chiron initially moves off with two turbochargers in operation. The other two units are activated from about 3,800 rpm.

The new high-performance tyres, once again developed by Bugatti together with its strategic tyre partner Michelin, now face extreme loading. At a speed of 400 km/h, centrifugal force converts one gram of rubber into 3,600 grams. A tire valve that only weighs 18.3 grams when stationary develops a hefty force of approximately 45 kilograms at that speed.

Only 32.6 seconds and just 2,621 metres later, the Chiron reaches the 400 km/h mark. With extremely fast reactions, Juan Pablo Montoya steps firmly on the brakes. Only 0.8 seconds after operation of the brakes, the rear wing, with a width of 1.50 metres, moves up to an angle of 49 degrees, forming an air brake that decelerates the Chiron extremely effectively. In the Top Speed mode at 400 km/h, the airbrake boosts the aerodynamic downforce on the rear axle by about 900 kg. That corresponds to the kerb weight of a Golf II. During full braking with a Chiron from 400 km/h, the force on vehicle and driver is about 2 g, similar to that experienced during the launch of a space shuttle.

The brakes of the Chiron, with their special carbon ceramic brake discs (diameter of 420 mm at the front, 400 mm at the rear) and brake calipers developed especially for Bugatti with eight titanium pistons on each wheel at the front and six at the rear, develop absolutely peak performance. After an incredible 9.3 seconds and 491 metres, the Chiron comes to a halt.

ON THE ROAD


The V-Box 3i, the GPS-based measurement system used by the inspectors from independent testing and certification company SGS/TÜV Saar which supervised the tests, indicated 41.96 seconds. During this time, the Chiron only covered a distance of 3,112 metres. This means that the Chiron is significantly faster than its predecessor, the Bugatti Veyron 16.4, which raised a furore with its performance and caused an upheaval in the automobile world at the time.

The Chiron has set the yardstick for this driving manoeuvre extremely high. Wolfgang Dürheimer, President of Bugatti Automobiles S.A.S., says: “Bugatti is the first car brand that not only calculates how fast a car can go from zero to 400 to zero on a computer. We actually drove it. Where others are satisfied with theory, we validate our data with real-life values. Just like we did with the Chiron.”

“Our customers want the best of the best. This truly impressive performance further confirms that the Chiron is the world’s best super sports car,” adds Dürheimer. “300 of the limited series of 500 Chiron have already been sold. The success story of this exceptional super sports car continues.“

For its 0-400-0 project, Bugatti invited Juan Pablo Montoya, a proven speed and performance expert. He accepted the invitation without any hesitation. “My first thought was that I would do anything Bugatti wanted in order to drive this incredible car.”

The former Formula 1 driver, who is now active in the IndyCar series, was especially impressed by the fact that a super sports car actually felt like a normal road vehicle. “When you are driving the Chiron for the first time and taking it easy, you cannot imagine how powerful it is. But as soon as you open the throttle, you hear the turbochargers pull up and all this torque comes in, and it just does not stop. It is like a linear power curve to happiness.”

Montoya is thrilled at the acceleration and braking performance of the Chiron. “The Chiron is so incredibly fast it takes your breath away. And its braking is at least as impressive,” is how he describes his impressions following the record run. “And the car is just so stable and consistent. I feel honoured to be part of this project.”

Following a test lap, the 41-year-old from Colombia decided not to wear the usual safety gear such as racing suit, helmet or HANS (head and neck support) device for the record run. “Of course, the Chiron is a super sports car that requires your full attention when you are behind the wheel. At the same time, it gave me such a feeling of security and reliability that I was entirely relaxed and really enjoyed myself during my two days with the car.”

During the world record weekend, Juan Pablo Montoya travelled faster than 400 km/h 17 times and also had an opportunity to improve his own personal speed record of 407 km/h, recorded with an IndyCar racing car to 420 km/h with the Chiron. “It really was incredible to see that you didn’t need the complex preparations we have to make in racing for the 0-400- 0 drive,” said Montoya. “With the Chiron, it was all quite easy. Just get in and drive off. Incredible.”

“I hope Bugatti will invite me to their world record run with the Chiron. At any rate, I’m saving the date in my calendar,” says Juan Pablo Montoya. In 2018, Bugatti plans to set a new world speed record in excess of the top speed of 431.072 km/h recorded with the Veyron 16.4 Super Sport in 2010.

  • The first vehicles are delivered to customers at the same time as the Geneva International Motor Show
  • Test drives for customers to start at the end of March
  • Bugatti exhibits new exposed carbon fibre colour “Bleu Royal” at the Geneva International Motor Show

One year after the world premiere of the Chiron1 in Geneva, Bugatti draws a positive balance. Half of the total series of 500 vehicles have already found a buyer – even without test drives. At the end of March, the French super sports car brand is inviting its customers to a central test drive event. With 37 percent of all sales, Europe is the strongest region, as was the case with the Veyron, followed by North America with 30 percent of orders to date. The Middle East, with 26 percent, is another key traditional market for Bugatti. Within the next few days, the first vehicles are to be delivered to customers. At this year’s Geneva International Motor Show (9 to 19 March 2017), Bugatti is showing a Chiron produced for a customer in the new exposed carbon fibre colour “Bleu Royal”. The luxury brand from Molsheim is a market leader in terms of the variety of colours and the quality of visible carbon.


THE ATELIER


Wolfgang Dürheimer, President of Bugatti Automobiles S.A.S., drew a positive balance concerning the past 12 months before the start of the motor show. “The Chiron got off to a fantastic start with its tremendous world premiere here in Geneva last year,” he said. “Over the months that followed, we kept our foot on the gas, started series production and are now delivering the first vehicles to our customers.”

IN DEPTH REVIEW: INTERIOR AND EXTERIOR


Highly advanced technologies and innovative solutions make for a superlative super sports car

How can you develop a new super sports car if you have already built the best? This was the steep challenge faced by Bugatti engineers in the development of the Chiron. The development brief for the new Bugatti was short and sweet – make the best significantly better in every respect.

Willi Netuschil, Board of Management Member and Head of Development at Bugatti, describes the technical approach: “Where other manufacturers stop, Bugatti goes a step further. We probe the limits. In our development work, we use all the technologies that are available, without any restrictions. Our aim is to be the best in the final resort.”

Powertrain

Newly developed W16 engine

1,500 HP was the power target for the Chiron. To achieve this objective, the eight-litre W16 engine which is already well-known to customers and fans was completely redesigned. To achieve a power boost of 25 percent compared with the predecessor, almost every component of the engine was considered and redesigned. To compensate for the weight increase caused by the high power output, greater use is made of lightweight materials such as titanium and carbon fibre. For example, the intake tube, the charge air system and the chain housing are all made of carbon fibre. The weight of the new crankshaft has also been optimised.

The key factors in the increased power output are higher-performance turbochargers and duplex fuel injection with 32 injectors. In addition, the charge air cooling system has been improved. As a result, more than 60,000 litres of air per minute are pumped through the engine. The coolant pump is also a very high-performance unit. In one minute, it circulates 800 litres of water through the entire engine.

Two-stage turbocharging is the outstanding technical feature of the powertrainThe engine is fitted with four larger, higher-performance turbochargers. They are operated in a two-stage configuration. The two-stage turbocharging system developed by Bugatti especially for this car is the outstanding technical feature of the Chiron powertrain. To ensure maximum acceleration from a standstill without the “turbo lag” feared by sports car drivers, the Chiron moves off the mark with only two turbochargers in operation. The other two units are only activated at about 3,800 rpm. As a result, the two-stage turbocharging delivers an absolutely linear power curve from 2,000 rpm, huge torque in the low engine speed range and a power output that can be controlled and dosed rather well.

New titanium exhaust system / the main catalytic converters are about six times as large as the unit fitted to a medium-sized carAnother feature that boosts the power output is the new titanium exhaust system with reduced exhaust gas back pressure. The system is fully insulated and equipped with four pre-converters and two main catalytic converters which are considerably larger than their predecessors. The main converters are about six times as large as the unit fitted to a medium-sized car. The total active surface of the six converters used for exhaust gas treatment is about 230,266 m², corresponding to the area of more than 30 soccer fields. From the catalytic converters, the exhaust gas is fed to a silencer which is extremely light compared with similar units, weighing only 20 kg. While other manufacturers use stainless steel, the silencer of the Chiron is made from titanium. The exhaust system is rounded off by six tailpipes, with four routed to the rear and two pointing downwards.

The transmission has the largest, highest-performance clutch fitted to a passenger carThe powertrain features a front-axle differential with integrated inter-axle lock and a rear-axle differential with integrated inter-wheel lock and a seven-speed dual-clutch gearbox designed for a torque of 1,600 Nm. This gearbox developed especially by Bugatti has the largest, highest-performance clutch used on a passenger car. It goes almost without saying that the Chiron has permanent four-wheel drive.


MAKING OF THE BUGATTI VISION GRAN TURISMO


Structure

Highly sophisticated monocoque with extremely high rigidity – LMP1 level

The monocoque of the Chiron is made entirely from carbon fibre and is designed for crash protection. This newly developed unit is the technically most sophisticated monocoque in its class. For the first time, the rear end of the car is also made from carbon fibre. If all the fibres used in the monocoque were laid out end to end, they would stretch nine times the distance between the earth and the moon. The production of a monocoque takes four weeks.

Thanks to the use of high-performance high-tech materials, the structure of the Chiron at the rear end is 8 kg lighter than that of its predecessor. The structure is completed by a carbon fibre underbody manufactured by an innovative sandwich procedure. The sandwich construction, combined with optimised material use, results in a weight saving of 8 kg compared with conventional construction. The structure of a sports car is not only the decisive factor in its weight but also in its rigidity. The Chiron reaches a torsional rigidity of 50,000 Nm per degree and a flexural rigidity of about 0.25 mm per tonne. These are sensationally good values comparable to those of LMP1 racing cars.

First airbag in the world to shoot through a carbon fibre housingThe new design of the Chiron also meets all the latest worldwide safety standards. The Chiron boasts the most advanced airbag technology available, with a total of six airbags. Thanks to Bugatti’s outstanding expertise in airbag design, it proved possible to develop an airbag that shoots through a carbon fibre housing. This is the case with the dashboard on the passenger’s side and the seat housings.

Carbon fibre body is an example of sophisticated craftsmanshipThe outer skin of the Chiron is made entirely from carbon fibre with perfectly aligned fibres flowing across the boundaries of neighbouring components without any optical interruption. This alignment, which is the result of skilful handcrafting and uncompromising attention to detail, makes the super sports car a real eyecatcher. Only the highest-quality carbon fibre fabric is used for visible carbon surfaces and six layers of clear coat are applied to ensure a perfect surface. Only Bugatti is so painstaking in this area.

In addition, some parts of the body require extremely complex production processes, such as the rear compartment lid or the wings. These do not have any edges or gaps but only fantastic reflections, which also applies to the side. Bugatti has succeeded in developing a body part that extends from the A-pillar to the rear in a single piece – an extremely sophisticated part that is simply beautiful to look at.

Last but not least, the new structure of the Chiron allows an optimised package and even more comfort. For the first time, it is possible to stow a suitcase with the size of a cabin trolley approved for air travel (44 litres) in the luggage space of a Bugatti. To provide this space, the radiator is installed in an inclined position, which also allows a larger cooling surface.
