Audi RS Q3 vs Mercedes-Benz GLA35

What's the difference?

Is 10 years long enough for a special birthday celebration? When you're a kid, hitting 'double figures' is a pretty big deal, and Audi's obviously in the mood to make some noise because it has lit the candles on a limited 10th anniversary version of its compact SUV rocket ship, the RS Q3.

Only 555 examples of the 'RS Q3 Sportback edition 10 years' will be produced for worldwide consumption, with Audi Australia capturing a batch of them and sending one our way for a brief blast as the fiery five-cylinder starts filtering into dealerships.

Fast SUVs, we can't get enough of them. The fastest of the small SUV set was the previous-generation GLA 45, a high-riding version of AMG's bonkers A-Class hatchback. Tons of power, more ride height (and, by extension, a better ride) and an obnoxious soundtrack.

It had its problems - the GLA was literally just a jacked up A-Class, so it had tight rear legroom and a chintzy interior but for me it was the pick of the two cars because it didn't rearrange your spine and, perversely, was more fun to drive.

This year, we got the second generation GLA which built on the success of the first GLA. While, yes, it is a jacked-up A-Class, it is much more of an actual SUV and with it comes more space, more of its own personality and, like its hatchback sibling, there's a new high-performance version, the GLA 35 to sit under the even more bonkers GLA 45.
