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?

2015 Audi S1 Summary

Spoilt. That's what we are. If you're in the market for a hot hatch, you can have your pick of German-built and French ones from as little as $27,000. There isn't a dud among them now that the VW Polo GTI has had a bit of an update and you can pick and choose your style. Audi's S1 is aiming to be king of the kids with its stiffly-priced S1.

Set the finances aside and consider for a moment what's on offer. As it turns out, a lot.

Deep dive comparison

2026 BMW i Series 2015 Audi S1

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

Cars this small shouldn't be this fast and useable at the same time, but the Audi S1 is. It isn't without its problems - the ride is harder even than the Fiesta ST which might weary some prospective buyers.

It's also a bit difficult to justify the price - in its basic form it's missing a few creature comforts that you'd expect in a $50,000 car - reversing camera, high-res screen, that sort of thing.

However, in the hot hatch world, those things don't matter. It has the bragging rights, the tech and the outright blinding speed to take on the bonkers Focus ST and equally zany Megane RS. And even the Audi S3.
