When the Bolide was first revealed as a thought experiment in late 2020, it introduced a imaginative and prescient of a light-weight, track-only hyper sports activities automotive delivering incomparable efficiency, constructed across the iconic W16 engine. That bold dream is being remodeled into actuality, because the Bolide prototype begins its subsequent part of growth testing.
At The Quail, A Motorsports Gathering in August 2021, Bugatti introduced that the Bolide can be developed for a restricted manufacturing run of simply 40 models. Centered on the premise of making the final word track-only Bugatti and set to be probably the most uncompromising mannequin to ever emerge from Molsheim, it represents a wholly new stage of engineering, aerodynamic, and technological innovation. For the Bolide, Bugatti began with the quad-turbo W16 engine after which constructed the lightest attainable automotive round it. Its minimal bodywork is designed rigorously to leverage most downforce, probably the most environment friendly cooling and distinctive power-to-weight ratio. In its closing kind, the Bolide is predicted to ship 1,600 PS and a dry weight of just one,450 kg to higher the magical 1:1 ratio.
Christophe Piochon, President of Bugatti Vehicles, mentioned: “The Bolide is treading new floor for Bugatti. By no means earlier than has such a strong engine been paired with an ultra-lightweight design to create a monitor automotive that delivers motorsport ranges of efficiency. Virtually each part has been analyzed and redesigned to make sure Bolide is as gentle, succesful and dependable as our strict targets require it to be. The subsequent part of growth is a significant milestone within the creation of a automotive that takes Bugatti’s ‘kind follows efficiency’ philosophy to a brand new stage.”
Creating the Bolide is a case of bespoke craftsmanship. Though the engine could also be aware of its format and capability, it’s built-in into the Bolide in a completely totally different means. A newly formed carbon monocoque in contrast with Chiron² meant re-engineering many elements, together with cooling, transmission, and suspension, every of which now needed to be packaged throughout the extremely compact and aerodynamic design of Bolide, with a matter of millimeters to spare. With new engine mountings, the suspension of Bolide’s drive unit is 3 times stiffer than the Chiron’s. Along with the uni-ball suspension bearings, the Bolide provides the driving force much more exact suggestions. The Bolide additionally makes use of 3D-printed titanium rockers to assist create intricately formed and light-weight elements.
The engine itself is central to the Bolide expertise, however subtly tailored for this automotive’s distinctive character. It at all times operates on all 4 of its turbochargers – excellent for the racetrack the place engine revs are persistently excessive, but in addition for weight and packaging causes. The crew has tuned the engine to ship larger revs per minute and efficiently paired it to a modified transmission designed to ship even sharper efficiency.
The braking system presents totally new ranges of efficiency and innovation. Within the Chiron, the brakes are an efficient and long-lasting carbon ceramic system however the Bolide makes use of much more heat-resistant carbon-carbon brakes. These should be completely warmed earlier than they attain their peak effectiveness so Bugatti engineers designed utterly new calipers that may extra effectively generate and take in warmth. With 18-inch tires, 390 mm brake discs have been created and a carbon cowl was positioned on every wheel to assist defend the edges from the acute warmth generated by the brakes.
Befitting its standing as a monitor automotive with the efficiency of a top-level motorsport machine, the Bolide is fitted with slick tires which – on the rear – can solely be discovered on LMDh automobiles racing within the FIA World Endurance Championship. Because of tire producer Michelin’s long-standing partnership with Bugatti, these tires can be utilized for the Bolide. First deliveries of the Bolide will start in 2024, with manufacturing restricted to only 40 models at a internet unit value of 4 million euros every.
