Compare the Audi RS3 vs Mercedes-Benz AMG A45
AI generated from our expert reviews
If outright practicality matters, the Mercedes-Benz AMG A45 delivers more power as well as a larger boot, offering extra capacity both with the rear seats up and with them folded. Even so, carrying three passengers across the rear bench is a squeeze in both cars. Both feature slick infotainment systems that are simple to navigate on the move, but you will notice differences from behind the wheel. The Audi RS3 proves a bit more fun in the bends on twisty roads than the Mercedes-Benz, balancing its smaller luggage area with an especially entertaining drive.
