The Bugatti Chiron Sport. £2.85 million pounds of precision engineering and carbon fibre wiper blades, all driven by an 8-litre quad turbo W16 engine. With 1,479bhp on tap, it’s got a theoretical top speed of 420kmh. Or 261mph in British. Theoretical… because no one outside Bugatti has ever hit it. Well, until they let Charlie Turner (Top Gear’s Editor-in-Chief) have a go.
