Chronology
PredecessorBugatti Veyron

The Bugatti Chiron is a mid-engine two-seater sports car developed and manufactured in Molsheim, France by French automobile manufacturer Bugatti Automobiles S.A.S.. The successor to the Bugatti Veyron,[6] the Chiron was first shown at the Geneva Motor Show on 1 March 2016.[7][8] The car is based on the Bugatti Vision Gran Turismo concept car.

The car is named after the Monegasque driver Louis Chiron.[9] The car shares the name with the 1999 Bugatti 18/3 Chiron concept car.

Specifications and performance

Two-tone paint is a distinctive option
The quad-turbocharged W16 engine of the Chiron with attached dual-clutch transmission

The main carry over component from the Veyron is the 7,993 cc (8.0 L) quad-turbocharged W16 engine, though it is heavily updated. The engine in the Chiron has a peak power output of 1,103 kW (1,479 hp; 1,500 PS) at 6,700 rpm and 1,600 N⋅m (1,180 lb⋅ft) of torque starting from 2,000 to 6,000 rpm.[10] The engine in the most powerful variant of its predecessor, the Veyron Super Sport generates 220 kW (295 hp; 299 PS) less than the new Chiron, while the engine in the original Veyron generates 367 kW (492 hp; 499 PS) less power.[11][12]

Like its predecessor, the Veyron, the Chiron utilises a carbon fibre body structure, independent suspension and a Haldex All-wheel drive system.[13][14][15] The carbon fibre body has a stiffness of 50,000 Nm per degree.[16]

The Chiron can accelerate from 0–100 km/h (0–62 mph) in 2.4 seconds according to the manufacturer, 0–200 km/h (0–124 mph) in 6.5 seconds and 0–300 km/h (0–186 mph) in 13.6 seconds. In a world-record-setting test at the time in 2017, the Chiron reached 400 km/h (249 mph) in 32.6 seconds, after which it needed 9.4 seconds to brake to standstill.[17]

The Chiron's top speed is electronically limited to 420 km/h (261 mph), or 375–380 km/h (233–236 mph) without the specific key, for safety reasons, mainly arising from the tyres as the manufacturer concluded that no tyre currently manufactured would be able to handle the stress at the top speed the Chiron is capable of achieving.[2][18] Independent testing by an owner has indicated that the Chiron can easily attain its limited top speed.[19] Mixed fuel consumption is 22.5 L/100 km (12.55 mpg‑imp; 10.45 mpg‑US).[20]

Sales

The first 200 cars were sold before the first was delivered.[21] The base price is €2,400,000[22][21] and buyers were required to place a €200,000 deposit before their purchase.[21]

Variants

Chiron Sport (2018–present)

Bugatti Chiron Sport at the 2018 Geneva Motor Show

At the 2018 Geneva Motor Show, Bugatti unveiled the track focused version of the Chiron, named the Chiron Sport. Mechanically the car is identical to the regular version, generating 1,103 kW (1,479 hp; 1,500 PS) from a quad-turbocharged W16 engine but is 18 kg (40 lb) lighter due to the extensive use of carbon fibre and has a stiffer suspension in order to increase the cornering ability of the car while maintaining its grand touring characteristics. The steering wheel of the car has also received modifications and a torque vectoring system to control the power sent to each wheel of the car for improved handling in tight corners has been added. Aerodynamic improvements and light weight have been given special consideration in order to keep the car competitive on the race track. The Chiron Sport became available in late 2018 for an additional US$400,000 on the standard Chiron.[23][5]

110 Ans Bugatti (2019–present)

Introduced in February 2019, the 110 Ans Bugatti is a limited edition variant of the Chiron Sport developed to celebrate 110 years of Bugatti. The car features carbon fibre body work finished in matte Steel Blue exterior colour. The body is also accented with Steel Blue bare carbon fibre. The exhaust system of the car is finished in matte black colour.

The colours of the French flag are present on the wing mirrors, fuel filler cap and on the underside of the rear wing. The brake callipers are finished in blue colour.

The interior of the car is upholstered in blue Alcantara and also has the colours of the French flag present on the headrests of the seats, on the back of the seats and on top of the steering wheel. Production will be limited to 20 units.[24][25]

Chiron Super Sport 300+ (2020–present)

On 2 August 2019[26] Bugatti presented a limited production high performance variant of the Chiron called the Chiron Super Sport 300+ to owners taking part in the company's 110th-anniversary tour in Europe. The variant is limited to 30 examples and closely resembles the prototype performing the top speed record run. Changes from the standard Chiron include a more powerful engine, increased top speed and a characteristic paint scheme featuring a lacquer coated carbon fibre body with orange stripes, echoing the aesthetics of company's previous top speed record breaking car, the Veyron Super Sport.

The car is powered by a 1,176 kW (1,577 hp; 1,599 PS) quad-turbocharged W16 engine shared with the Bugatti Centodieci, nicknamed "Thor". This car has a grey Bugatti logo made of black enamel and silver, the exhaust system from the Centodieci, a modified gearbox with longer ratios and front and rear bumpers optimised for aerodynamics at high speed, resulting in the overall length increase of the car by 248.9 mm (9.8 in).

The Super Sport will also be equipped with a top speed limiter, akin to the one found in the standard Chiron. Without the limiter, Bugatti claims that the car can attain a maximum speed in excess of 483 km/h (300 mph). Bugatti will also prepare the cars of owners who want to take the car to its full potential at the Ehra-Lessien test track.[27][28][29][30][31]

Chiron Pur Sport (2020–present)

On March 3, 2020, Bugatti introduced the Chiron Pur Sport, a handling-focused model which will be limited to 60 units. The tachometer has an additional 200 rpm, increasing the redline to 6,900 rpm. 80 percent of the transmission has been revised for a 15 percent closer gear-ratio spread benefiting the power band. The Pur Sport is 50 kg (110 lb) lighter than the standard Chiron due to a lightweight 3D printed titanium exhaust, a fixed rear spoiler and extensive use of alcantara, anodized aluminium and titanium on the interior. The wheels have special spokes called "aero blades" which are designed to channel turbulent air near the wheel down the side of the vehicle to the rear diffuser. The tyres are Michelin Sport Cup 2R increasing lateral grip by 10 percent, and were co-developed with Michelin. To improve handling, the springs were made 65 percent stiffer at the front and 33 percent at the rear, aided by revised damper tuning and wheel camber along with additional front and rear carbon-fibre anti-roll bars and a new Sport+ drive mode. Production of the Pur Sport is expected to start in late 2020.[32][33]

Chiron Noire (2020–present)

Bugatti announced a special-edition Chiron Noire model based on the $12.5 million La Voiture Noire. The special edition comes in two versions, the Noire Élégance and Noire Sportive, and only 20 will be made. The Noire starts at around $3.3 million, and deliveries are expected to begin in mid-2020[34]

Bugatti La Voiture Noire

The La Voiture Noire is a one-off special introduced at the 2019 Geneva Motor Show. Based on the Chiron, the design of the car harkens back to the Type 57 SC Atlantic and is a celebration of the company's distinctive design history. The car has a hand-built body made from carbon fibre designed by Bugatti designer Etienne Salomé which has an elongated nose (similar to that on the Divo) and an elongated rear section. Other notable features include unique wing mirrors, LED taillight strip and wheels. Unlike the original, the car retains the mid-engine layout.

A trim piece running from the front of the car to the rear spoiler recalls the dorsal fin present on the Type 57 SC. The car features a floating windscreen and has masked A pillars.

The La Voiture Noire will be powered by the same 8.0-litre quad turbocharged W16 engine from the Chiron having the same power output figures but the 7-speed dual-clutch gearbox and the all-wheel-drive system are heavily revised in order to allow for a more relaxed driving experience. Softer dampers and a revised chassis contribute to the factor. The car features six exhaust pipes recalling the innovative design of the past.

Performance figures remain unknown but the company states that the car is likely to have a lower top speed and acceleration times as compared to the Chiron due to its Grand Touring nature. The car was sold for a price of €11 million, making it one of the most expensive cars built to date.[35][36]

A statement made later by the company confirmed that the car on display was a concept car and that the final product would take two and a half years more to complete. The show car had electric motors instead of an engine for easy maneuverability.[37][38]

The Bugatti Chiron record car on display at the 2017 IAA show. Note that the number 42 on the grille signifies the overall rounded off time of the 0-400-0 acceleration and braking record

At the 2017 IAA show in Frankfurt, Bugatti announced that the Chiron broke the record of fastest 0–400–0 km/h (0–249–0 mph) acceleration time, completing it in 41.96 seconds in a span of 3.2 kilometres (2 miles) at the Ehra-Lessien high-speed oval. The car was driven by Colombian racing driver Juan Pablo Montoya.[39][40][41]

Bugatti also added an extra livery to the Chiron on display to confirm that it was the same car that broke the 0–400–0 km/h record.[42] During the show, Bugatti also mentioned that during the run, the car accelerated from 0–100 km/h (0–62 mph) in 2.4 seconds, 0–200 km/h (0–124 mph) in 6.1 seconds, 0–300 km/h (0–186 mph) in 13.1 seconds, and 0–400 km/h (0–248.5 mph) in 32.6 seconds, which altogether, also makes the Chiron faster than its predecessor, the Veyron.[42]

Top speed achievement

On 2 August 2019, Bugatti test driver Andy Wallace achieved a speed of 490.48 km/h (304.77 mph) in a pre-production Chiron Super Sport 300+ prototype at Volkswagen's test facility in Ehra-Lessien. The speed was verified by the TÜV, Germany's Technical Inspection Association, making it the first time a production vehicle has broken the 300 mph barrier.[43]

The car was developed under Bugatti head exterior designer Frank Heyl in collaboration with Italian automobile engineering firm Dallara and tyre manufacturer Michelin over the course of six months. The overall length of the car was increased by 248.9 mm (9.8 in) and it is fitted by a laser controlled ride height system in order to reduce drag. To further reduce drag and aid aerodynamics, the electronically controlled rear wing was removed and was replaced with a long tail incorporating a rear wing with a short cross section. A full roll cage was added for safety reasons, and the passenger seat was removed to make way for data recording equipment used to validate the record run. The car incorporates an exhaust system first introduced on the Bugatti Centodieci in order to further reduce aerodynamic drag. Mechanically, the engine was modified to generate 1,177 kW (1,578 hp; 1,600 PS) of power output with no changes to the gearbox and all-wheel-drive system.[44][45]

Marketing

The Chiron was recreated in Lego as 2018's annual Technic sports car. It was released on 1 June 2018 as a 1:8 scale model with 3,600 individual parts.[46]

On 30 August 2018, Lego unveiled a working full sized model of the Chiron. It was constructed almost entirely with Lego Technic elements (339 unique types, over 1,000,000 pieces in total) with exceptions for the Bugatti badge, the wheels, a steel frame, a steel roll cage, a steel drive chain and the seat belts. The engine was created from 2,304 Lego Power Function motors found in standard models; it was estimated to produce 4 kW (5.4 hp; 5.4 PS) and 92 N⋅m (68 lb⋅ft) of torque. The car was test driven by Andy Wallace, Bugatti's official test driver, at Volkswagen's Ehra-Lessien test track.[47][48]
