Andy Wallace talks us through the engineering that went into creating the Bugatti Chiron.
The Bugatti Chiron is one of the fastest, most expensive and the most luxurious hypercars ever built. The car was first unveiled in 2016 and half of the production run has already been sold out. But, this is our first look at the engineering that went to creating this car. Carfection’s Henry Catchpole met up with Andy Wallace – Le Mans winner and the man who set the production car world record for the highest top speed in a McLaren F1 in 1998 for a quick chat about the Chiron.
The video was filmed at Bugatti’s HQ in Molsheim, France. The site includes the factory where the Chiron is built, also known as the Atelier and other buildings from Ettore Bugatti’s era. Wallace and Catchpole talk about the factory’s history and then make their way towards an actual W16 engine and gearbox from a Chiron placed in one of the rooms. Wallace gets into the nitty-gritties of the enormous engine which is an extensive evolution of the Veyron’s power unit. There are two turbochargers for low rpm operation, supplanted by two others that take over at 3100 rpm, he explains.
The exhaust system is made of titanium and weighs only 21 kilos (46 pounds). The catalytic converter is six times the size of one on a midsize car and provides a total exhaust scrubbing area as big as 30 soccer fields. The entire engine is adorned with visible carbon fiber parts, some even patented. Further, Wallace explains how the aerodynamics on the Chiron work. He also talks about its brakes and that famous ‘Speed Key’.
