how was the “ultimate roadster” born?

Bugatti has lifted the veil on some design secrets of its new W16 Mistral, presented as the “ultimate roadster” in its history, armed with the legendary 1,600 horsepower W16 engine.

Bugatti details the design of its new W16 Mistral, dubbed the “most ultimate roadster in its history” responsible for continuing the myth of 16 cylinder engine will end

“It is important, to reach more than 420 km/h with an open-top vehicle, to have effective management of both thermodynamics and aerodynamics, and more than a 1,600 hp engine, certainly the most advanced ever created »Explain Emilio Cervo, CTO at Bugatti Rimac.

“We had to think carefully about how the shape of the W16 Mistral would guide the air in and around the car to strike a good balance between optimal cooling and aerodynamics. »

Between artistic vision and mastery of the laws of physics

In front of the W16 Mistral, there is a wider, deeper and three-dimensional reinterpretation of the already famous horseshoe grill from Molsheim. This makes it possible to supply air, from an inlet, to the radiator with a high engine temperature, reserving the two side air intakes for Cooling system.

The air flow that flows around the front ends is led into two inlets: one near the wheel and the other integrated into new three-dimensional headlights. As it passes through the tires, air is guided from an area of ​​high pressure to an area of ​​low pressure to prevent turbulence phenomena and drag that can affect performance.

“The frontal appearance of the car is dominated by these large air intakes and, although the Bugatti touch is immediately recognisable, we also bring some elements from some models such as the Divo, Centodieci and The Black Car, adds up Achim AnscheidtDesign Director of Bugatti Rimac.“The windscreen wraps around the pillars forming an elegant visor and the front of the vehicle is vertical to create a design that is both speed optimized and elegant. »

A line in C is revisited

The profile of the new roadster includes a line version in C revisited which characterizes Chiron in particular. The line around the side air intake now extends upper edge of side windows, then in a three-dimensional way to that of the windshield.

“To do it right, we need to separate the engine air intake from the oil cooler air intake. » detailed Achim Anscheidt. “If we put them together, the entrances on each side of the vehicle should be disproportionately enlarged. »

“So we prefer to rely on what was done for the Veyron 16.4 Speed​​​​​​​​​​ and the Type 57 Roadster Grand Raid by integrating the engine intake behind the headrests. »

“This solution is elegant, functional and safe at the same time; the thin side air intakes therefore only supply air to the oil coolers, while the engine air intakes now take place behind the headrests. »

Taillights in “X”, as in Bolide

The air drawn through the side inlets is ducted at the level of two radiators located on each side of the vehicle, then it passes through the rear wheels and then exits the taillight in the shape of an “X”; as in Quickly.

The flows emerge through triangular cavities located between fire rays in “X”thus creating a pressure drop between the side air intakes and the rear outlets, which helps to adjust engine temperature, even though very busy.

“The W16 Mistral can reach 420 km/h in ‘Top Speed’ mode, while giving the driver a sense of absolute safety”continued Emilio Scervo. “Offering total control of our cars regardless of conditions and speed is an important part of Bugatti’s DNA.

“To make this possible with the W16 Mistral, the aerodynamic configuration of the car had to be carefully thought out. It offers both high downforce and maximum drag reduction. »

“This balance is due to the specific spoiler in front of it, under its body and the high flow of air that passes on both sides of the streamlined rear wing when it is deployed. »

A highlight in Bugatti history

In fashion top speed, W16 Mistral will run with a minimum rear wing tilt to reduce drag. The rear diffuser is also optimized because the force created by a diffuser generates very little drag.

The edge of the diffuser is raised to increase its angle of inclination and its expansion rate, which contributes to maintaining the excellent maneuverability of the W16 Mistral and to the consolidation of its maximum speed.

“The W16 Mistral symbolizes a high point in Bugatti’s history”, Achim concluded. “This is the kind of car that we will see on the lawns of the greatest Concours d’Elegance for ten, even hundreds of years. »

“We have created a timeless interior for this vehicle, including the selection of intricately woven leather, thoroughly tested and manufactured to Bugatti quality standards, for the door panels specially designed for the W16 Mistral . »

“And as a nod to its famous ancestors, such as the Type 41 Royale, the gear lever, made from a solid block of aluminum, features a wood handle and an amber insert that incorporates the famous sculpture of the dancing elephant by Rembrandt Bugatti. »
