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

The new Bugatti Chiron, the successor to the original Veyron, was revealed the Geneva motor show this week.

It has a colossal 1479bhp, can reach 62mph in less than 2.5sec - despite weighing 1995kg - and has a maximum top speed of 261mph.

Previewed by the Vision Gran Turismo concept car at last year’s Frankfurt motor show, the immensely powerful Chiron aims to occupy the position its highly celebrated predecessor held at the very top of the supercar ladder, one rung above the McLaren P1, Ferrari LaFerrari and Porsche 918 Spyder – all of which have now ceased production.

Bugatti describes the second of its modern day models as the most powerful road car to ever reach series production. However, with volumes set to be limited to 500 and a price to match its extreme performance at an eye watering €2.4 million (about £1.9 million) it will remain out of reach for all but the seriously rich. 

Bugatti boss Wolfgang Dürheimer portrays the quad-turbocharged 8.0-litre W16 powered Chiron as an all-new car that uses little from the Veyron. 

But while the new Bugatti has been comprehensively re-engineered and now features a full carbonfibre construction, it adopts a similar mechanical package to its record-breaking predecessor. 

At its heart is a heavily revised version of the quad-turbocharged 8.0-litre W16 configured petrol engine used by the Veyron. With a faintly absurd 1479bhp developed at 6750rpm, the mid-mounted unit delivers 492bhp more than the engine used by the Veyron – in the process providing the Chiron with a power-to-weight ratio of 741bhp per tonne. Torque has also risen by a substantial 257lb ft, peaking at 1179lb ft on a band of revs between 2000 and 6000rpm.

According to Bugatti's official figures, the Chiron achieves fuel economy of 12.5mpg on a combined cycle - that's 8.0mpg urban and 18.6mpg extra-urban. CO2 emissions stand at 516g/km. For comparison, the original Veyron emitted 586g/km CO2, and achieved 11.3mpg on a combined cycle; 6.7mpg urban and 18.1mpg extra-urban.

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.

“Our customers form an exclusive group of automobile collectors who are searching for the very best. With the Veyron, they have the best production sports car of the past 10 years. This is why their demands and expectations for our next step – the Chiron – were so high.

“With the Chiron we will not only be providing a key emotional element for the image of the Volkswagen Group but will also be making a positive contribution to Group results.”

Interestingly, Bugatti says that the Chiron’s 261mph top speed is “by no means the end of the road” for the car – hinting that even more may be possible in the future.

"Where others have stepped Bugatti has gone one step further. We have taken the boundaries even further - there are no boundaries we haven't pushed. The Chiron is a new superlative in the automotive world.

The new model racked more than 310,500 miles in development testing. A total of 30 test mules were build while the car was honed. Officials have admitted that the Gran Turismo concept car was a direct preview of the new model.
