2016 Bugatti Chiron - every detail on the Veyron's 260mph+ successor

Among the more significant developments brought to the Bugatti powerplant is a redesigned carbonfibre inlet manifold, heavily reworked injection system featuring 32 individual injectors, larger and more powerful turbochargers, a revised intercooler system and new titanium exhaust system with a total of six catalysers that is claimed to provide a substantial reduction in back pressure over the old system.

In a bid to provide the new Chiron with what Bugatti describes as a more linear delivery of power than the Veyron, the new turbochargers are operated in a two-stage process; during step off just two turbochargers function initially, with the remaining two joining in to boost performance when the engine speed rises above 3800rpm.

The colossal reserves are channeled through a reworked version of the Veyron’s seven-speed dual clutch gearbox and multi-plate clutch four-wheel-drive system; the latter has an electronically controlled differential that provides a torque-vectoring function to vary the amount of drive apportioned to each of the rear wheels and the basis for what Bugatti dubs an “easy to drift” function.

While it is yet to undergo final certification testing, Bugatti has released preliminary performance figures suggesting it has achieved its stated aim of making the Chiron faster than the Veyron with claims of 0-to-62mph in under 2.5sec, 0 to 124mph in less than 6.5sec and 0 to 186mph below 13.6sec.

By comparison, the Veyron posted official times of 2.5sec, 7.3sec and 16.7sec respectively.

As before, top speed is limited in two stages; the so-called handling mode allows 236mph before the electrics step in, and the top-speed mode provides a maximum of 261mph, eclipsing the Veyron by 7mph. 

The chassis of the Chiron is a clear development of the Veyron’s. In a bid to improve ride quality without compromising body control, it adopts an adaptive suspension system, providing variable ride height and damping control.

In combination with variable characteristics for a new electro-mechanical steering system and the four-wheel-drive system, the driver can choose between five driving modes: Lift, Auto, Autobahn, Handling and Top Speed.

The Lift mode increases the ride height for speed bumps, while in Auto, Autobahn and Handling modes the top speed is limited to 236mph. To engage Top Speed mode, the Chiron requires a ‘Speed Key’, which alters the engine management system to provide the claimed 261mph maximum.

Reining in the vast performance are 420mm front and 400mm rear carbon-ceramic discs grabbed by eight-pot and six-pot calipers respectively. They provide the Chiron with a claimed 62 to 0mph in 31.3m, 124 to 0mph in 125m and 186 to 0mph in 275m – in each case eclipsing the various claimed braking distances of its predecessor.

Borrowing strong visual cues from the earlier Veyron, the new Chiron features an even more dramatic design with tauter surfacing, bolder details and added aerodynamic efficiency than that of the car it replaces. The man credited with the new appearance, Bugatti design boss Achim Anscheidt, says it was developed in close collaboration with Bugatti’s engineering team to ensure greater functionality without any loss in overall impact.

Key design elements include a race-grade front splitter, large horizontal air ducts, a traditional horseshoe-shaped grille sporting a Bugatti badge fashioned from silver and enamel, distinctive LED headlamps – each with four individual lenses and integrated air ducts that feed cooling air to the front brakes, shapely front wings and a flamboyant semicircular sweep of bodywork extending from the trailing edge of its front wheelarches back towards the rear and into the A-pillars – the latter flourish clearly inspired by the look originally established by Jean Bugatti on the iconic Type 57.

As on the Type 57, there is also a prominent centre fin running from the top of the grille across the bonnet and into the heavily rounded roof, providing an important contribution to the Chiron’s longitudinal stability, according to Bugatti. A NACA duct formed by shapely rear pillars replaces the individual air scoops used by the Veyron, channeling air into the engine bay more efficiently and with less turbulence than on its predecessor. 

It is at the rear where the more significant differences in appearance between the Veyron and Chiron are apparent, with a strong trailing edge, fully integrated rear spoiler, full width LED light band housing the tail lamps, indicators and reserving lamp, sizeable air ducts, large central mounted exhaust and race grade diffuser providing the new Bugatti with a particularly purposeful appearance from behind. 

Dimensionally, the Chiron remains close to its predecessor. At 4544mm long, 2038mm wide and 1212mm tall, it is 82mm longer, 40mm wider and 53mm higher than the Veyron. The similarities also extend to the wheelbase, which is just 1mm longer, at 2711mm. The Chiron sits on 285/30 R20 ZR tyres at the front, with 355/25 R21 ZR rubber at the rear.

The basis for the new Bugatti is provided by a newly developed carbonfibre monocoque structure of the same standard as that used in Audi and Porsche's LMP1 cars. In a departure from that used by the Veyron, it adopts a sandwich construction for the floor and a carbonfibre-reinforced plastic engine cradle at the rear for added stiffness and lower structure weight. Yet achieving the sort of stiffness achieved by the latest LMP1 race cars, the Chiron is155kg heavier than its predecessor at 1995kg.

The increase in width has brought greater space to the two-seat interior and in particular the front wheel wells of the Chiron, according to Bugatti. Greater height has also liberated 12mm extra headroom compared with the Veyron.

The cabin is trimmed in a combination of leather, carbonfibre and brushed aluminium. Among the new developments is a passenger airbag that deploys through carbonfibre – a first for a production vehicle.

The Chiron will be assembled at Bugatti’s headquarters in Mosheim, France. So far, Bugatti has received more than 150 orders for the new car, and deliveries will begin in October.

Further variants of the Chiron are planned to be launched, including successor models to the Veyron Grand Sport, Veyron SuperSport and Veyron Grand Vitesse.

The Chiron name is taken from the 1920s and 1930s grand prix racer Louis Chiron, whose notable results included victory in the 1931 French Grand Prix at the wheel of a Bugatti Type 51.

Announcing the new model, Dürheimer said: “The Chiron is the quintessential ultimate super sports car: ultra-modern, incredibly fast, agile and powerful with a stylistically demanding design and the highest possible levels of comfort. This combination is not offered by any other market player and gives Bugatti its unique market position.
