Costs & verdict
Everyday costs, plus how reliable and safe it is
If you think that buying a 444bhp coupé is a good way to save money, you’ve probably got your calculator the wrong way up. Even so, the RS5 compares well with rivals from BMW and Mercedes. The C63 Coupé is pricier to buy but the similarly powerful M4 with an automatic gearbox is more expensive. The Sportback, meanwhile, is pretty evenly matched to the C63 Saloon and Alfa Romeo Giulia Quadrifoglio, price-wise.
Carbon emissions are par for the course in this class; as is the case for its rivals, it falls into the top 37% benefit-in-kind company car tax bracket. Claimed economy is much better than the previous V8 RS5 but still lags slightly behind the competition.
