Success and innovation in motorsport has been inseparably linked to Bugatti for more than 100 years, since the Type 13 achieved the iconic brand’s first victory at the Grand Prix de la Sarthe in 1920. The one-of-a-kind Type 35, which hit the track four years later, cemented Bugatti’s reputation for building beautiful and successful racing cars, achieving more than 2,000 victories and podium finishes during its long and distinguished competition career.

This incomparable motorsport heritage, combined with cutting-edge technology and absolute engineering excellence, has led the Bolide 1 to embody Bugatti’s vision of the last exclusive hyperdeportivo for the track. In order to design the Bolide to fit as closely as possible to the brand’s legendary 8.0-litre W16 turbocharged engine, it was necessary to develop a new advanced monocoque made from the highest quality carbon fiber composites, which normallyI only know used in Formula 1 and Le Mans racing cars.

The Bolide’s new monohull reflects the proportions of an elegant catamaran, meaning driver and passenger sit perfectly balanced inside the car. This arrangement also allows the incomparable W16 powertrain to be positioned 60mm further forward than in the Chiron, ensuring ideal packaging for track use. As a result, the engine benefits from a new arrangement that allows it to be optimally integrated within the monocoque. The incredible performance of the Bolide required an even stronger and more rigid monocoque than that of the Chiron. The Fédération Internationale de l’Automobile (FIA) safety requirements for the LMH and LMDh standards for Le Mans racing cars drove the development of the new structure and were chosen because they are among the most stringent safety standards in the world. world of motorsport. Additionally, crash test requirements for track-only race cars are unique, fostering the need for a clean, uncompromising design.

For a hyper sports car inspired by motorsport greatness (a defining element of the Bolide’s features), safety factors such as rollover protection are paramount, and one of the FIA’s most demanding tests requires a load of 7.5 tons applied to the A-pillar of the vehicle. To pass the test, the maximum deflection must not be more than 50 mm at the point where the load is applied, and no failure of the structure is permitted within 100 mm of that point. This means that small localized cracks are allowed at the point of impact. However, when the Bolide was tested, there were no cracks, thanks to the structural integrity inherent in the monocoque design, and especially in the angle of the A-pillar, its cross section and the high-tech materials used. In a second rollover test, an even higher load (12 tonnes) was applied to the B-pillar.

To ensure even higher levels of safety, Bolide is equipped with a military-grade automatic fire extinguisher system that represents a significant all-round safety improvement compared to the fire extinguisher units widely used in conventional racing cars. To improve entry and exit from the two-seat cabin, the outer sections of the wraparound headrests are attached to the dihedral doors. Designed to GT3 regulations in line with automotive packaging requirements, they are attached to the door frame using an X-shaped bracket, which is a structural component as the headrest test load is applied to the outside of the door. . Created by Bugatti’s design and engineering teams, the stand is made of 3D printed aluminum and, although it weighs just 300 grams, it can support a load of more than 700 kg.

Inside the Bolide, the driver and co-driver are secured with an FIA-approved six-point harness system. In addition to keeping occupants firmly in place during the extreme forces generated during cornering, acceleration and braking (in some cases extending up to 2.5 g), they provide the highest levels of safety possible. The seats are also tested to LMH standards and occupants will benefit not only from their high levels of safety but also from the optimal comfort that has been designed into the seats to provide a fatigue-free driving experience. For even greater safety, the Bolide’s cockpit is compatible with the motorsport-proven ‘HANS Head And Neck Support’ system.

Additionally, the Bolide’s next-generation passive safety features are perfectly complemented by motorsports-leading active safety technologies, including traction control, electronic stability control and an anti-lock braking system, ensuring the Bolide is always stable and ready to compete no matter what happens. weather conditions. A high-performance climate control system allows Bolide owners to race their Bugatti in sweltering conditions that would be challenging or even impossible for many other racing cars.

As a result, the uncompromising nature of this extraordinary hypercar puts it in a class of its own. Powered by the legendary W16 engine, the Bolide generates 1,600 HP at 7,000 rpm and 1,600 Nm at 2,250 rpm. With a dry weight of just 1,450 kg and a downforce of almost 3,000 kg at maximum speed, Bolide offers a truly exciting, dynamic and track-focused driving experience. However, it is a unique experience that does not come at the expense of refinement: thanks to features such as climate control, power steering and ergonomically designed seats, both driver and co-driver can enjoy lap after lap of their favorite circuit. with comfort and safety.
