2026 BMW i Series Summary

We’re in the new BMW iX3, the first production model to arrive on BMW’s Neue Klasse (new class) EV architecture. We’re testing the flagship 50 xDrive, and it begs the question: has BMW actually managed to make its next generation of EVs feel like a proper Bimmer? Buyers expect a lot from that badge when it comes to ride and handling, so does this electric SUV actually deliver?

2021 Audi RS5 Summary

Audi's A5 Coupe and Sportback have always been good looking cars. Yes, yes, beauty is in the eye of the beholder and all that, but seriously, just look at one and tell me it's not handsome.

Happily, the just-updated RS5 doesn't just build on the looks of its more sedate sibling, but on the performance, too, adding near-supercar speed to those supermodel looks.

Sounds like a pretty good match, right? Let's find out, shall we?

Verdict

The BMW iX3 50 xDrive is a seriously quick electric SUV that earns points for its family practicality, while its impressive range could go a long way towards easing range anxiety. The ride isn’t always as settled as I’d like, but for the most part, this is a well-executed premium EV.

Verdict

Good looking, good to drive, and good to simply sit in, the Audi RS5 range ticks plenty of premium boxes. Whether you can live with the practicality pitfalls of the Coupe is up to you, but if you can't, might I suggest taking a wander over to our RS4 Avant review?
