1. Bugatti Chiron: The 2005 Veyron was a game-changer but rather than drop the mic and walk off stage, content, Bugatti raised the bar in 2016 with the Chiron. It carried over the Veyron’s 8.0-litre quad-turbocharged W16 engine and produced 1,479 horses and had a top speed of 420kph. So in terms of envelope-pushing performance it is without a doubt one of the most important cars of the decade.
