Bugatti has at last confirmed that it is taking the outlandish Bolide track car into production, nearly a year since it was unveiled in digital form as an experimental concept.

Just 40 examples of the skeletal track car will be built over the next three years, priced at €4 million (£3.4m) apiece, following "a great deal of enthusiasm and intrigue" for the concept at its unveiling. Owners will initially be invited to sample the car's performance at dedicated track events, so that they can be gradually introduced to its "breathtaking performance".

Described as “the most extreme, uncompromising, fastest and lightest vehicle concept” in the brand’s modern age, the Bolide weighs just 1450kg and makes use of Bugatti's now-venerable quad-turbocharged 8.0-litre W16 engine, powering all four wheels, and pumped up well beyond the 1578bhp it puts out in the Chiron Super Sport 300+ to a maximum of 1825bhp when using 110-octane racing fuel.

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

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

There’s also air-to-air intercooling with water pre-cooling to keep temperatures down, while the brakes are kept ventilated by carbon-titanium radial 'turbofan' compressors. Three air-cooled oil-coolers, again with water pre-cooling, also feature for the engine, transmission and differential.  

Just as much effort has gone into keeping the kerb weight down to that 1450kg figure. As well as using a “minimal body for maximum downforce”, the Bolide sits on a super-light and super-stiff carbonfibre monocoque. Carbonfibre is also used in the front-end and underbody. Bugatti claims the carbonfibre’s tensile strength is matched only by that used in the aerospace industry.

Furthermore, all screws and fastening elements are titanium, while super-thin aerospace-grade hollow titanium alloy, originating from 3D printers, is used for many components. Ceramic brakes feature callipers that weight just 2.4kg each, with centre-lock forged aluminium wheels weighing 7.4kg at the front and 8.4kg at the rear. 

Those are shod in tyres with extreme width - up to 340mm at the front and 400mm at the rear, while there’s even a compressed-air-driven jack with four rams designed to make tyre changes easier. 

The suspension is by titanium pushrods with horizontal dampers. The pushrods themselves weigh just 100g. Welded stainless-steel control arms are also designed as wing profiles. 

The dramatic bodywork itself is shaped, unsurprisingly, with aerodynamics in mind. Bugatti claims 1800kg of downforce on the rear wing and 800kg on the front wing at around 200mph.

Highlights include a “worldwide innovation” in the roof-mounted intake scoop, which is claimed to provide active aerodynamics: the surface of the scoop is smooth at low speeds but bubbles bulge out at higher speeds to reduce drag and downforce. 

“In my 16 years at Bugatti, I've never worked on a more extreme concept,” said design boss Achim Anscheidt, who also admits the project was “more technically driven than shaped by style”.

The Bolide is very low-slung and just 995mm tall - 300mm lower than the Chiron. It has doors that fold upwards, like an LMP1 racing car. Air ducts are said to link to the aesthetics of Formula 1 cars, while the ‘X’ theme used throughout (in particular in the rear light designs) are meant to refer to the Bell X-1 experimental jet aircraft that Chuck Yeager piloted to become the first person to break the sound barrier in 1947. 

As for performance, Bugatti claims a theoretical top speed of “well above” 311mph, without compromising handling. More strikingly, it claims the Bolide can do a lap of Le Mans in 3:07.1 minutes and a lap of the Nürburgring Nordschleife in 5:23.1 minutes - barely a few seconds off the lap record posted by the Porsche 919 Evo LMP1 car.

“Driving the Bolide is like riding on a cannonball,” said Winkelmann.  

Interestingly, Bugatti says the car features safety equipment designed to meet FIA racing regulations. There are also references to the iconic Bugatti Type 35 racer of the 1920s. It remains to be seen if there is any racing intent with the new car, but there are long-circulating suggestions that Bugatti could eventually enter the Le Mans 24 Hours endurance race.

Damn!  This, a T20 or a Valkyrie?  If you can afford any you can afford them all, and it's too hard to choose only one!
