The next-generation high performance wagon will once more sport a wider track, and flared front and rear wheel arches. Lowered suspension, all-wheel drive, and subtly aggressive front and rear bumpers will also part of the deal.
Gone is the old model's naturally-aspirated 4.2-litre V8, replaced with a new 2.9-litre twin-turbo V6 that develops 600Nm of torque between 1900 and 5000rpm, as well as 331kW of power.
That means that the new RS5 and RS4 will have 170Nm more torque than their predecessors.
Equipped with the V6, the new RS5 coupe is able to race from 0-100km/h in 3.9 seconds, or 0.8 seconds quicker than before. The new RS4 Avant may a bit little slower to the performance milestone due to its larger body and longer wheelbase.
It's likely that the new RS4 Avant will make its debut at the Frankfurt motor show in September. If that turns out to be the case, the fast wagon won't go on sale in Australia until some time in 2018.
