Bugatti has achieved what it calls “the most extreme, uncompromising, fastest and lightest vehicle concept” of the brand’s modern era.Called the Bolide, the track-oriented model promises an astonishing power-to-weight ratio of 0.67 kg per horse. This translates to 1,825 hp for a vehicle weight of just 1,240 kg – roughly the same curb weight as the Ford Fiesta ST.

Both of these figures are made possible by the use of Bugatti’s now venerable 8.0-liter four-turbocharged W16 engine, powering all four wheels, far beyond the 1,578 horsepower it produces in the Chiron Super Sport 300+.

“For the first time, we are showing what the W16 engine is really capable of,” said Stefan Winklemann, Bugatti boss.

This is done via an intake and exhaust system, four newly developed turbochargers and a redesigned dry sump lubrication system, with Bugatti claiming a reduction in powertrain weight.

There is also air-to-air intercooling with water pre-cooling to keep temperatures low, while the brakes are kept ventilated by carbon-titanium radial double-flow compressors. Three air-cooled oil coolers, always with water pre-cooling, are also provided for the engine, transmission and differential.

It should be noted, however, that the claimed maximum horsepower is only achieved using 110 octane racing fuel. Using 98 octane gasoline, the figure is actually the same 1,578 hp as the Super Sport 300+.

Just as much effort has been made to keep the curb weight at this figure of 1240 kg. In addition to using a “minimal body for maximum downforce”, the Bolide is based on an ultra-light and ultra-rigid carbon fiber monocoque. Carbon fiber is also used in the front and underbody. Bugatti claims that the tensile strength of carbon fiber is only matched by that used in the aerospace industry.

Additionally, all screws and fasteners are made of titanium, while ultra-thin, aerospace-grade hollow titanium alloy, sourced from 3D printers, is used for many components. The ceramic brakes feature calipers weighing just 2.4kg each, with center-locking forged aluminum wheels weighing 7.4kg in the front and 8.4kg in the rear.

These are shod with extremely wide tires – up to 340mm at the front and 400mm at the rear, while there is even a compressed air jack with four cylinders designed to facilitate shifting. tires.

The suspension is by titanium lifters with horizontal shock absorbers. The pushers themselves weigh only 100g. The welded stainless steel suspension arms are also designed as wing profiles.
