Mystery of Bugatti's New Hypercar Solved

The figure of 0.67, which did not give rest to fans of the brand, has turned out to be a power-to-weight ratio.

The French company unveiled a track prototype called the Bolide. This is a hypercar that has the potential to break several speed records, although the automaker does not set such goals. Shortly before the premiere of the mysterious car, the company distributed teasers in social networks with a mysterious figure of 0.67. But it has recently turned out that this is a power-to-weight ratio.

The Bolide is 4,756 mm in length, 1,998 mm in width, 995 mm in height and 2,750 mm in wheelbase. Bugatti’s engineers drew on the experience of the aerospace industry and Formula One in order to reduce the weight of the structure as much as possible. As a result, it is only 1,240 kg. Given that the car is driven by an uprated quad turbo W16 engine borrowed from the Chiron. The unit has a power-to-weight ratio of just 0.67 kg/hp. It produces 1,850 hp and 1850 Nm on a 110 octane leaded race fuel (a power output on 98 RON is 1,600 hp).

All bolts and fasteners of the Bolide are made of titanium. A number of functional components are made of an aerospace alloy. An auxiliary cardan shaft of the hypercar is a 0.5-meter 3D-printed composite part made of carbon fiber and titanium.

According to the automaker, the hypercar's aerodynamic body kit generates 800 kg of downforce in the front end of the body and 1,800 kg in the rear end at a speed of 320 km/h.

Bugatti says the Bolide's top speed “significantly exceeds 500 km/h without compromising handling and maneuverability”.

The hypercar accelerates from 0-100 km/h in 2.17 seconds and from 0-200 km/h in 4.36 seconds. It takes 7.37 seconds to accelerate from 0-300 km/h, 12.08 seconds from 0-400 km/h and 20.16 seconds from 0-500 km/h.

The Bugatti Bolide spends 24.64 seconds on the 0-400-0 km/h exercise. For comparison, the Chiron does this in 41.96 seconds, and the Koenigsegg Regera — in 31.49 seconds. In theory, Bugatti would have at least one record in its pocket if the Bolide had access to public roads like the Regera.

One of the features of the Bolide is a shape-changing air intake housing on the roof. Its surface remains absolutely smooth at low speeds and covers with “bubbles” at high speeds. Thanks to them, air resistance is reduced by 10 percent, and the lifting force on this element is reduced by 17 percent.

The company cites other figures. For example, a computer simulation shows that the Bolide is able to pass the Nurburgring in 5 minutes and 23.1 seconds. This time is as close as possible to the current speed record, which was set by the Porsche 919 Hybrid Evo 2 years ago (5 minutes and 19.55 seconds).

Last year, Bugatti CEO Stefan Winkelmann said that the company would no longer chase speed records. “We have demonstrated several times that we make the fastest cars in the world, and the 300 mph [483 km/h] mark was our last record in this area,” he said at the time. However, this statement could only apply to passenger vehicles, which the Bolide does not belong to.
