The Audi RS5 is the fastest car we have tested this year. With a 0-100kmph time of 4.29 seconds, it undercuts the BMW 530d M Sport by 1.44 seconds, which is a lot in the racing world. It is also 0.91 seconds faster than the Ford Mustang, which was the fastest car we tested in 2017. The Audi RS5 is the maddest and the most powerful member of the A5 brat pack which includes the A5, S5 and the A5 Cabriolet. It’s a very capable car and an all-rounder. It’s fast, it’s comfortable in the city and can munch miles all day long while consuming relatively less fuel. In essence, it is the perfect car for someone who likes his weekend trips but doesn’t want something too serious like the BMW M4. The RS5 is powered by a 2.9-litre bi-turbo V6 petrol engine that makes 456PS/600Nm. Power is sent to all four wheels via Audi’s quattro all-wheel-drive system and an 8-speed gearbox.
