Now that the 2021 Audi A3 Sportback has debuted, it's only a matter of time before America's sedan version arrives. Beyond the standard A3, Audi is also cooking up hot new versions of the S3 and RS3. Last year, Audi was caught testing a mule for the RS3, but this is the real deal. Our spies have caught prototypes of the production Audi RS3 Sportback and sedan facelifts being put through their paces in the snow preparing to battle the Mercedes-AMG CLA 45.

Both prototypes are covered in camouflage, but we have a clear idea of what they will look like since the A3 Sportback has already debuted.

In terms of styling, the 2021 Audi A3 has been updated with a wider grille and digital daytime running lights featuring 15 LEDs.

Compared to the regular A3, the new RS3 looks more aggressive thanks to its wider fenders and a more menacing-looking front bumper. Like the regular A3, the new RS3 will only be sold as a sedan in America. We get a clear look at the RS3 Sportback from all angles, but our spies only managed to capture the RS3 sedan from the rear flaunting Audi Sport's signature oval tailpipes.

Inside, the new Audi A3's cabin has been updated with a 10.1-inch touch display and a 10.25-inch digital instrument cluster as standard, which will carry over to the RS3.

Under the hood, the Audi A3 is offered with a choice of three engine options including a 1.5-liter TFSI gasoline engine with 150 horsepower and a 2.0-liter TDI diesel with up to 150 hp. The new Audi RS3, on the other hand, will pack an updated version of Audi's 2.5-liter five-cylinder turbo engine. In the current RS3, this unit develops 400 hp, but the new RS3 could get a small power boost. An official debut date hasn't been announced, but the 2021 Audi S3 and RS3 should break cover later this year.
