Bugatti unveils its latest model in California
WWith the Divo, Bugatti has developed a super sports car tuned for agility, nimbleness and optimum handling performance on winding roads. It is powered by Bugatti’s iconic eight-litre W16 engine with a power output of 1,500 PS. The aerodynamics of the model have been intensively fine-tuned, and the suspension and chassis settings have been modified. As a result, the Divo is 35 kilograms lighter and has 90 kilograms more downforce than the standard Chiron. The lateral acceleration of the Divo has been boosted to 1.6 g and its maximum speed is limited to 380km/h. The Divo can lap the Nardò handling circuit in southern Italy eight seconds faster than the Chiron. The series will only consist of 40 vehicles. Upon the start of presentations to selected customers, the strictly limited small series, with a net unit price of €5 million, sold out immediately.
Bugatti is also reviving its coachbuilding tradition, in its first few
decades, the French luxury brand had considerable success with bodies built to its own design and installed on existing chassis. The aerodynamic properties of the Divo were improved by a considerable amount of detailed work. The front cover is equipped with air intakes which reduce the effective cross-sectional area of the vehicle at the same time as ensuring improved air flow at the front and increasing aerodynamic efficiency. An optimized “air curtain” makes for better air flow over the front and rear sections of the car’s sides. The newly-designed, wide front spoiler provides higher downforce and guides more air to the front air inlets. The cooling system therefore receives a higher mass flow and overall cooling performance is improved.
The brakes are cooled by four independent air sources on each side of the vehicle, air flows in from the high-pressure area above the front bumper, the inlets on the front wings, one inlet on the front radiator and the diffusers ahead of the tyres. Vanes direct the cold air from these areas onto the brake discs. A heat shield carries the hot air out through the wheels. This means that the brakes do not overheat, and the tyre temperature is always kept in the optimum range. This system, which is already used on the Chiron, receives additional support from the vacuum generated by the air curtain on the tyres in the case of the Divo. In addition, the wheel arches are ventilated via slats on the wings.
The roof of the Divo has been designed to form a NACA air duct, a flow-optimized air inlet. In combination with the specially designed engine compartment cover, this ensures a very high air mass flow to the engine compartment, playing a key role in temperature management in this area of the vehicle.
The rear end of the Divo features a new, height-adjustable rear spoiler which functions as an air brake when turned forwards and is set to different angles for the individual driving modes. The rear spoiler has a width of 1.83 metres and is 23 percent wider than on the Chiron. The wider spoiler improves efficiency and results in higher air brake performance as well as significantly more downforce. The downforce is also boosted by the rear diffuser which has been entirely redesigned for greater efficiency and accommodates four tailpipes. The total downforce generated is 456 kilograms, 90kg more than on the Chiron.
The main objective of chassis development work was to improve cornering dynamics of the Divo, for this purpose, the camber was increased. As a result the maximum speed of the Divo is limited to 380km/h, in contrast to the Chiron where there is no Top Speed mode. The steering and suspension have been set to ensure more direct response and significantly sportier driving behaviour in all modes.
The Divo is 35 kilograms lighter than the Chiron, the weight reduction is the result of a number of lightweight design modifications including new lightweight wheels and a carbon fibre intercooler cover. Weight was also saved by modifying the front diffuser flaps, a reduction in the amount of insulation material used and the installation of a lighter sound system. In order to reduce the weight, stowage compartments on the central console and in the door, trims have also been omitted. The Divo can therefore lap the Nardò handling circuit eight seconds faster than the Chiron.
The design team continued the evolution of the design elements for the Divo in line with the design brief and reinterpreted the design philosophy “Form follows Performance”. The outer skin of the Divo was designed in an uncompromising way to emphasize lateral acceleration. The main objective
was to achieve optimum aerodynamic and thermodynamic efficiency. At the same time, the Divo represents a new styling approach which the design team has developed especially for a coach-built Bugatti.
Technical innovations in the interior include the seats, which not only feature a new design but offer greater lateral support. The steering wheel is partly covered with Alcantara and has larger paddles fitted firmly on both sides of the wheel. Thanks to larger armrests and calf supports, the central console ensures greater comfort.
