[14][15] Like its predecessor, the Veyron, the Chiron utilises a carbon fibre body structure, independent suspension and a Haldex All-wheel drive system.

Mechanically the car is identical to the regular version, generating 1,500 PS (1,105 kW; 1,480 hp) from a quad-turbocharged W16 engine but is 18 kg (40 lb) lighter due to a lighter, more unrestricted exhaust system, the extensive use of carbon fibre, and a stiffer suspension in order to increase the cornering ability of the car while maintaining its grand touring characteristics.

In April 2022, Bugatti issued a factory recall for a 2018 Chiron, built 16 November 2017, due to a loose front frame support screw.

The car features carbon fibre bodywork finished in matte Steel Blue exterior colour.

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 the company's previous top speed record-breaking cars, the Veyron Super Sport World Record Edition and the Veyron Grand Sport Vitesse World Record Car.

The car is powered by a 1,600 PS (1,175 kW; 1,580 hp) quad-turbocharged W16 engine shared with the Bugatti Centodieci, nicknamed "Thor".

The car features a new grill, a French flag behind the front wheels, a matte grey ("Gris Serpent") exterior colour with a gloss white stripe in the centre.

It is the first project of Bugatti's new ‘Sur Mesure’ (meaning tailored in French) customization program, so it is a one-off car.

The number 32 was displayed in bold letters on their racing car and is now hand painted on the doors of the Chiron Pur Sport 'Grand Prix'.

Bugatti also made changes to the steering and suspension systems, and it gave the seven-speed, dual-clutch automatic transmission 15% shorter gear ratios.

[59] Bugatti had planned to build 30 units, but as the production of its pre-series vehicle started, all 500 Chiron slots were already assigned.

The project was cancelled and the car never entered production thus only one example was built and it is fully street-legal in European markets.

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 La Voiture Noire's shares large design similarities from the Bugatti Rembrandt, a cancelled front-engine grand tourer powered by the Chiron's W16 engine.

Performance figures remain unknown but the company states that the car is likely to have lower top speed and acceleration times as compared to the Chiron due to its Grand Touring nature.

[64][65] Differing from the show car, the real La Voiture Noire has a Cognac (Brown) Leather Interior and a fully-functioning drivetrain with its W16 engine sourced from the Chiron.

[66] La Voiture Noire is owned by a member of the family of the late Ferdinand Piëch, the man for whom the car was initially commissioned (though he died before receiving it).

A number of newspapers, tabloids, and online blogs created and spread false claims that Portuguese footballer Cristiano Ronaldo was the owner of the vehicle.

[67][68] This rumour, which is believed to have originated with a report from Spanish sports newspaper Marca[69] was denied by a spokesperson for Ronaldo.

[70] 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 on a weekend in August 2017.

[72][73][74] 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 (0–249–0 mph) record.

In its final production form, the Chiron SS 300+ has different seats, no roll-cage, standard ride height and an electronically limited top speed of 440 km/h (273.4 mph).

[76][77] 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.

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.

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) and 92 N⋅m (68 lb⋅ft) of torque.
