2021 Mercedes-Benz GLA35 Summary

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.

2026 Cadillac Optiq Summary

The lonely Cadillac Lyriq finally has some company, with the iconic US brand tripling its range down under with the launch of the much bigger Vistiq (which we've already tested) and this entry-level Optiq, which Cadillac describes as the gateway to its electric family.

It's a medium all-electric SUV with plenty of equipment and – depending on whether you see it as an established premium player or another newcomer brand – pretty sharp pricing.

Cadillac says it has the German big three in its sights with the Optiq, so how does it stack up?
