The latest RS5 is no more powerful than before with 444bhp, but weight savings of 60kg mean it’s faster than its predecessor. For instance, the firm claims the 0-62mph sprint is covered in an electrifying 3.9 seconds, while we recorded our own 0-60mph time of 3.6 seconds – neither the M4 nor C63 can duck under the four second barrier. What’s more, the combination of launch control and four-wheel drive mean that this figure can be achieved come rain or shine.
However, it’s fair to say the RS5 never feels as dramatic as the figures suggest. Make no mistake; the Audi is a seriously quick car that can cover ground with truly indecent haste. Yet the extremely linear power delivery (peak torque of 442lb ft is delivered at 1,900rpm) means you’re treated to a smooth and relentless increase in pace, rather than the more exciting top end frenzy of, say, the M4.

Like all fast German machines, the RS5 is limited to a top speed of 155mph. Yet if you’re willing to fork out an extra £1,450 then Audi will raise this figure 174mph - useful if you live just down the road from an Autobahn.
