The Bugatti Chiron is a mid-engine two-seater sports car developed and manufactured in Molsheim, France by French automobile manufacturer Bugatti Automobiles, as the successor to the Bugatti Veyron. The Chiron was first shown at the Geneva Motor Show on 1 March 2016. The car is based on the Bugatti Vision Gran Turismo concept car. The car is named after the Monegasque driver Louis Chiron. The car shares the name with the 1999 Bugatti 18/3 Chiron concept car. 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) at 6,700 rpm and 1,600 Nm (1,180 lb ft) of torque starting from 2,000 to 6,000 rpm. The engine in the most powerful variant of its predecessor, the Veyron Super Sport generates 220 kW (295 bhp) less than the new Chiron, while the engine in the original Veyron generates 367 kW (492 hp) less power. Like its predecessor, the Veyron, the Chiron utilises a carbon fibre body structure, independent suspension and a Haldex All-wheel drive system. The carbon fibre body has a stiffness of 50,000 Nm per degree. The Chiron can accelerate from 0-97 km/h (0-60 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. 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. Independent testing by an owner has indicated that the Chiron can easily attain its limited top speed. Mixed fuel consumption is 22.5 L/100 km (12.55 mpg imp; 10.45 mpg US). The first 200 cars were sold before the first delivery of the car. At the 2018 Geneva Motor Show, Bugatti unveiled the track focused iteration of the Chiron dubbed the Chiron Sport. Mechanically, the car is identical to its regular counterpart generating 1,103 kW (1,479 hp) from a quad-turbocharged W16 engine but is 18 kg (40 lb) lighter due to the extensive use of carbon fibre and utilises 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 along with the introduction of a torque vectoring system to control the power sent to each wheel of the car for improved handling in tight corners. Aerodynamic improvements and light weight have been given special consideration in order to keep the car competitive on the race track. On August 2, 2019, 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 include a more powerful engine, increased top speed and a characteristic paint scheme featuring raw 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 1,177 kW (1,578 hp) quad-turbocharged W16 engine shared with the Bugatti Centodieci, nicknamed "Thor". This car has a grey Bugatti logo, 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 say the car can hit 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 Leissen test track. 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. 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. 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. On August 2, 2019, Bugatti test driver Andy Wallace reached 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 TUV, Germany's Technical Inspection Association, making it the first time a production vehicle has broken the 300 mph barrier. 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 along with a minimalist driver focused interior and the removal of a passenger seat reduce weight. 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) of power output with no changes to the gearbox and all-wheel-drive system. The Chiron was recreated in LEGO as 2018's annual Technic sports car. It was originally going to be released on August 1, 2018, but it was pushed to June 1, 2018. It is a 1:8 scale model with 3,600 individual parts. On 30 August 2018, LEGO unveiled a working life-size 1:1 scale 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) and 92 Nm (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.
