Bugatti Chiron Super Sport 300+
The Bugatti Chiron is easily one of the fastest cars in the world, and last year the company proved it. With Bugatti test driver and 24 Hours of Le Mans winner Andy Wallace at the helm, the Chiron recorded a top speed of 304.773 mph (490.484 km/h), making it the first production car to break 300 mph. To better reach and exceed the 300-mph barrier, Bugatti needed to make some design changes to the Chiron. The most noticeable update to the record-breaking car is located out back. The rear end has been lengthened and narrowed — referred to as a Longtail — resulting in significant drag reduction since there is less surface area for air to cling to at speed. With a modified exhaust pipe configuration, the diffuser in the center of the rear end can generate almost enough negative lift by itself, allowing the rear wing to remain retracted during high-speed runs.
