2026 Audi A5 Summary

The Audi A5 has done something naughty. It’s replaced the Audi A4.

Or at least that’s the case for now after the Ingolstadt brand made a bit of a mess of its naming strategy.

Essentially, the Audi A5 is now available as a sedan or a wagon, and the next A4 coming soon will be electric. The previous A5 was a swoopier two-door coupe or four-door gran coupe style model. So the A5 is now effectively Audi’s main BMW 3 Series or Mercedes C-Class and CLA rival.

Plus, the Audi S5 is also here to cater to performance car fans.

Can a new platform, a sleek, fresh look and a techy interior do the job?

We’ve been pedalling around the Victorian countryside in the hopes of finding out.

Stick with me, and I reckon we’ll get to the bottom of it. The question about the car, that is, not the bottom of Victoria.

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?

Verdict

The Audi A5 remains a convincing option in the premium mid-size sedan category, even with the near-$10K price increase over its equivalent grade A4 predecessor.

Even in its base spec, it’s a lovely thing to drive and adds enough new kit to be a reasonable option when it comes to value. In terms of tech usability, it stands out from rivals. Practicality is still king for Audi.

But for the heart-over-head types, the S5 is fast and fun while remaining a comfortable cruiser and the price is decent. On a personal note, a six-cylinder wagon? That's a big yes from me.

For the time it’s available, it’s hard to go past the value on offer in the S5 Edition One. Getting an AWD V6 with that kind of capability for under $100K is something that's sure to tempt buyers. If it doesn’t, we need to take a good look at ourselves.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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.
