Bugatti unveils fully dressed Chiron Sport at 2018 Geneva Motor Show

Article by Christian A., on March 7, 2018

The Bugatti Chiron is probably one of the sportiest cars in the planet, thanks to its overwhelming power output of 1,500 hp and its hypercar design. If there is one car who could claim to be sportier than the Chiron, it is another creation from the French manufacturer – the new Bugatti Chiron Sport.

Bugatti’s formula for creating a sportier version of the Chiron doesn’t entail any increase or boost in power output or torque. The French high-performance carmaker didn’t need to tinker with the quad-turbo, 8.0-liter W16 engine to come up with the Chiron Sport. This means that power ratings for the Chiron Sport remain at 1,500 hp of max output and 1,180 lb.-ft. (1,600 Nm) of peak torque as transmitted to all wheels. Likewise, this means that Chiron Sport could complete a sprint from zero to 60 mph in just 2.4 seconds, and achieve a top speed of up to 260 mph (420 km/h) – the same as the Chiron.

Aside from retaining the superb power and performance of the Chiron, the new Chiron Sport also features the same ease and convenience of driving. Instead of focusing on these elements, Bugatti decided to dramatically improve the handling of the new Chiron Sport and enhance its lateral dynamics on winding roads. To achieve this goal, the new Chiron Sport is fitted with a dynamic handling package and has been made lighter than the original model.

The new dynamic handling package for the new Chiron Sport includes a stiffer suspension, a new control strategy for the shock absorbers and a modified steering. This package is only activated when the Chiron Sport goes into Handling mode, as distinguished from the EB mode. Aside from an optimized rear-axle differential, the new Chiron Sport features a Dynamic Torque Vectoring function that individually sends torque to the wheels on each side.

Moreover, the new Chiron Sport is lighter than the Chiron by 18 kilograms, as achieved by employing new lightweight wheels and the more extensive use of carbon fiber on parts like the stabilizer, the newly developed aerodynamic windscreen wipers and the intercooler cover. In addition, the Chiron Sport comes with lighter rear glass window and lighter exhaust deflector.

The Chiron Sport is distinguished from the Chiron through details like the new “Course” alloy wheel rims and the new exhaust deflector with four round tailpipes. The Chiron Sport also has a number of elements finished in anodized black, like the engine starter button, the driving mode selector knob on the steering wheel and the marketing plate. The “Sport” logo is found on the door sill strips while the “Chiron Sport” logo is embroidered on the insert on the central console.

To give the Chiron Sport a sportier appearance, Bugatti’s design team developed a package of color and trim options. This allows customers to suit the appearance of the new Chiron Sport according to their taste and preferences.

Interestingly, the Bugatti Chiron Sport on display at the 2018 Geneva Motor Show is clothed with all the available options. This is why this particular Chiron Sport has a value of €2.98 million net (US$3.672 million gross), possibly making it the most expensive production car shown at the event this year.

“We have developed the Chiron Sport for customers wanting an even sportier driving experience with their Chiron, with improved lateral dynamics on winding roads,” says Stephan Winkelmann, President of Bugatti Automobiles S.A.S. “What was important for us was to leave unchanged the unique character of the Chiron, its combination of ultimate performance, longitudinal acceleration and maximum speed with luxury, comfort and everyday usability.”

This is why the extreme power and performance data of the Chiron as well as the ease and convenience of driving remain unchanged. There is however a significant improvement in the handling of the Chiron Sport.

“The Chiron Sport has become perceptibly more nimble and its new agility, especially in tight corners makes for a much more emotional experience for the driver on winding roads and handling circuits,” Winkelmann continues.

Dynamic handling package and lighter weight make Chiron Sport faster

The Chiron Sport benefits from a new dynamic handling package. The Bugatti developers have defined a stiffer suspension. This includes a new control strategy for the shock absorbers, which react 10 percent more stiffly than on the Chiron on average. The steering has also been modified without sacrificing its outstanding direct feel and its calculable performance. These new settings only take effect in the Handling mode of the Chiron Sport, which is therefore distinguished from the EB mode more clearly for the driver.

In addition to these changes, the rear-axle differential has been optimised and the car now features a Dynamic Torque Vectoring function that distributes torque individually to the wheels on each side, significantly improving the steering behaviour and agility of the vehicle, especially in tight curves. This change is effective in all driving modes.

One of the modifications which make the Chiron Sport more nimble is a weight reduction of about 18 kilograms, thanks to the use of new lightweight parts. The greatest savings were possible as a result of the new lightweight wheels, together with increased use of carbon fibre, for example for the stabiliser, the intercooler cover or the newly developed windscreen wipers. The Chiron Sport also features lighter glass in the rear window and a new, lighter exhaust deflector.

As a result, the Chiron Sport has become even more responsive and corners even faster. On the handling course of the Nardò test circuit, Bugatti developers recorded a lap time which is five seconds faster than the base Chiron model. Due to its design the Nardò circuit is especially well-suited as a reference track for the Chiron, as the super sports car can reach its full handling potential even at cornering speeds in excess of 200 km/h.

Bugatti is the first manufacturer to develop a carbon fibre windscreen wiper

The windscreen wiper arms developed by Bugatti for the Chiron Sport are an interesting technical detail. This is the first production car to feature windscreen wiper arms made from carbon fibre. This new development means that Bugatti no longer needs the articulated joints which normally feature on conventional wipers. The function of these joints has been integrated into the carbon fibre structure of the wiper arms. In addition, the wiper arm tips, which are made from aluminium, are produced by a weight-saving 3-D printing process. This means that the new carbon fibre wipers are 77 percent or 1.4 kg lighter than their predecessors.

In addition, thanks to the new material, the wiper arms have a new profile that allows improved aerodynamic properties.

New wheel rims and exhaust deflector distinguish Chiron Sport from Chiron

At first glance, the Chiron Sport can be recognised by its new “Course” alloy wheel rims and the new exhaust deflector, which has four round tailpipes instead of the rectangular design used on the Chiron. In addition, the Sport version has a number of design features that underline its identity as a Chiron Sport. For example, the engine starter button and the driving mode selector knob on the steering wheel as well as the marketing plate have an anodised black finish, the “Sport” logo is in evidence on the door sill strips and there is an insert on the central console with an embroidered “Chiron Sport” logo.

More colour and trim options available for an even sportier look

In addition, Bugatti’s design team has created a package of colour and trim options for the Chiron Sport allowing customers to give their vehicles the sportiest look possible. The Chiron Sport on show in Geneva features all the options available.

The vehicle body has a classic duo-tone colour scheme. The A-colour at the rear of the vehicle is determined by visible grey carbon; Italian Red paintwork at the front represents the B-colour. Apart from red, the colours available are “French Racing Blue”, the silver tone “Gris Rafale” and a dark grey “Gun Powder”.

The distinctive Bugatti side line, a C-shaped trim strip made from aluminium alloy, is painted in the B-colour, in this case “Italian Red”. This red tone is also to be found on the brake calipers, the EB logo on the hubcaps, the underside of the rear spoiler and in the labelling on the intercooler cover. Here, it creates an exciting contrast with the “Gun Powder” grey of the carbon fibre intercooler cover and the same tone which is used for paintwork on the wheel rims, the aluminium bezel of the Chiron’s iconic rear lights, the EB logo on the rear and the famous Bugatti horseshoe on the radiator grille.

A red “16” is positioned prominently on the black-painted grid of the radiator grille – referring to the number of cylinders which gives the Chiron engine its unique position.

Black is the dominant colour of the interior. All the controls of the car have a black anodised finish. The steering wheel and selector lever are covered with suede leather. In addition, Bugatti has used three materials for the styling of the interior: Alcantara for the roof liner including the A-pillar and sun blinds, the rear wall trim, the sill trims, the lower part of the central console, the insides of the seat side cushions and the boot lining. Smooth leather is used for the seats, the inside door trims, the islands on the dashboard including the instrument cluster trim, the airbag container on the steering wheel and the armrest and insert of the central console. Finally, the dashboard itself, the door trims, the rears of the backrests and the steering column housing are made from exposed carbon fibre.

The B-colour of the exterior, “Italian Red” on the Geneva show car, is used to create restrained but distinctive accents in the interior, for example on the stitching, the safety belt, the surround of the C-shaped light bar in the centre of the vehicle, the back of the rear-view mirror and the lining of the central console stowage compartment.

Including this optional colour and trim package, the Chiron Sport on show in Geneva costs €2.98 million net (US market: US$3.672 million gross), which probably makes it the most expensive production car on display at this year’s show.

The International Motor Show is being held at the Palexpo exhibition centre in Geneva from 8 to 18 March 2018. The Bugatti stand is in Hall 1.
