2025 Audi S5 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 Audi RS3 Summary

Five-cylinder fury is still kicking!

Audi has just launched the mid-life updated version of its RS3 hatch and sedan in Australia.

With new looks inside and out, the German carmaker has also made a number of subtle tweaks under the skin via software updates. Thankfully, however, the five-cylinder beast lurking under the bonnet remains untouched.

As the viability of pure internal combustion engines in the hot hatch segment dwindles in the age of ever-tightening emissions regulations, will this be the last hurrah for the five-banger RS3?

Read along to see how this latest version stacks up.

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.

Verdict

The Audi RS3 is a special hot hatch and sedan I’m so glad I experienced before its five-cylinder engine is inevitably retired due to emissions regulations. Full of character and charisma, this car is far from a rational purchase, pitched at boy racers who don’t want to grow up just yet.

From a value perspective, too, while the asking price has crossed the six-figure threshold and the option prices add thousands, it’s still much cheaper than the Mercedes-AMG A45 S. Make of that what you will.
