This is the new 2019 Audi RS5 Sportback, and it meets its elder, the 2013 Audi RS5 which costs less and offers V8 thrills. Both are fitted with the excellent 60:40 rear bias quattro system, and both fulfil the role of an Audi icon. The 2013 hits 60 mph in 4.5 seconds and the new one does it in 3.8 seconds. So can the old one stack up, and is the new one worth the massive premium? James and Thomas jump behind the wheel of both to experience them and discuss them inside and out. Watch and enjoy!
