Audi continues the development of the range-topping RS4 model, with Carscoops spies spotting them during some cold-weather testing.

Audi will continue using the gorgeous wide fenders in the RS4, with the rest of the bodywork getting the usual updates for a more menacing look, including new bumpers, a rear spoiler and a diffuser along with a nice big set of wheels.


RS4 will use the twin-turbo 2.9-litre V6 petrol unit that debuted in the Porsche Panamera. This particular engine makes 434 hp in the case of the Panamera 4S but Audi is expected to give it their own tune for an output of more than 450 hp. 0-100 km/h is expected to be dealt with in less than 4 seconds before hitting the top speed limiter at 250 km/h.

Audi will of course offer the option of raising the limiter to 280k m/h if you want your Autobahn trips to be a tad shorter in duration. The 2018 Audi RS4 is expected to debut at this year’s Frankfurt Motor Show, with the first cars to hit the road near the end of 2017.
