You'll immediately have seen what the problem is. As far as four door, hatchback saloons go, there's just the RS7 - the 560hp, £87,000 uber barge. But what if you want the same body style and sporty performance in a smaller, cheaper package? Until now, you've had to look at somewhat left field - and far less powerful - alternatives, cars like the Kia Stinger and BMW 440i Gran Coupe - or maybe even Audi's own S5 Sportback - but that's all about to change.
The permanent all-wheel drive will have something to do with it too, the system distributing power 40:60 front to rear under normal driving, though also capable of up to 85:15 or 30:70 to counter any "slippage", should it occur. An optional sport differential adds the ability to channel torque between the rear wheels (though expect it to be standard again for the UK, like the two-door), while Audi Sport's RS Sport Suspension Plus with Dynamic Ride Control, ceramic brakes, and RS-specific dynamic steering can also be included at extra cost.
Aesthetically, all of the usual Audi Sport cues are present; short overhangs, sinewy styling, honeycomb grilles and ovular tailpipes all make an appearance. While the sports suspension - resulting in a ride height 7mm lower than that of the standard S5 - and 15mm wider wheel arches ensure the stance is as it should be.
Speaking about the car Audi Sport MD, Michael-Julius Renz, said: "The Audi RS 5 Sportback is more than just an international trade fair novelty - it offers something new to our customers. Our innovative interpretation of a five-door high-performance coupe has neither predecessor models, nor a direct competitor," continuing: "we expect it to conquer all markets."
We'll have to wait until the autumn for it to conquer the UK market, though; the RS5 Sportback initially only set to be available in the US and Canada. When it does arrive here, it's expected to cost the same as the RS5 Coupe at £63,575, and it can be ordered from the summer. Much to the relief of RS fans everywhere.
