2021 BMW M2 vs 2023 Audi RS3

What's the difference?

When BMW’s M2 first landed on Australian shores in 2016, one of the biggest criticisms levelled at it was a lack of grunt, which must have hurt its feelings.

With 272kW and 465Nm from the 3.0-litre single-turbo ‘N55’ six-cylinder engine, it was hardly tame, but the question it raised was whether it was special enough to be christened a full-fat M car? And the answer from enthusiasts was "perhaps not".

Fast forward to 2018 and BMW had rectified that criticism with the M2 Competition, powered by a 3.0-litre twin-turbo ‘S55’ engine from the M3 and M4 to punch out a more exciting and appropriate 302kW/550Nm.

For anyone crazed enough to think that was still not enough, the M2 CS is now available in showrooms, and turns the wick up to 331kW and 550Nm, thanks to some tweaks to the engine. It's now available with a six-speed manual gearbox, too. That sound you hear is purists rejoicing.

So, does this now make the 2021 M2 CS the ultimate BMW for the enthusiast driver?

After teasing us with the S3, all-wheel-drive version of its A3 sedan and hatch (Sportback in Audi-speak), Audi has finally given us the full-fat, RS3 variant of the same car. Any time you see an `R’ and an `S’ on the badge of an Audi, you know it’s the full nine yards in terms of all-wheel-drive grip and engine performance. And the RS3 is no different.

The power is enormous, the grip prodigious and the attitude is way tougher than any other A3 variant. It’s also well equipped, safe and nicely put together. But is that extra `R’ worth the added price of admission? And is this more Audi A-Series than you really need?

The other question is, given that the S3 is such a resolved package with its own shot of high-performance, do the numbers stack up for the RS3 version? How much is too much?
