Audi doesn't appear to have big aesthetic changes ready for its hot TT.

The Audi TT RS is a fairly recent addition to the model range, but new spy shots indicate that a little refresh is already on the way for the range-topping variant of the small sports car. 

At the front, Audi is getting ready to whack on a new front end with a different design for the air intakes, including a number of slits near the centre of the spoiler. The headlights are also a little bit different – rather than the existing design where the LED running lights sit along the lower portion of the headlamp unit, the updated styling puts the strip at the top of the headlights. See, it's going to be completely different, you won't recognise the new car.

Audi has put heavy camouflage on the rear end of the revised car, and the swirly design does a good job of hiding the changes. A new set of rear lights is among the tweaks, though. The diffuser also appears somewhat less prominent than on the current TT RS. Which is probably a good thing.

In addition, the side sills appear to be a little thicker, particularly towards the rear of the vehicle. It lends the whole thing a suitably muscular air. You can have a look at the spy shots side-by-side with the current version of the car and decide for yourself, though.

These photos don't provide a good look at the cabin, but expect Audi to use the upgrade to make some infotainment system upgrades. Minor trim changes are likely, too.

The powertrain of the refreshed TT RS remains a complete mystery. However, the existing 2.5-litre turbocharged inline five-cylinder engine is already quite potent. It pumps out 400bhp and 354lb ft of torque. A seven-speed dual-clutch gearbox and all-wheel-drive system handle the job of getting all that power to the road. No idea when we might see the revised car – our next motor show opportunities will be the Detroit show in January and then Geneva in March 2018.
