2024 Audi RS4 Summary

It's the end of the line for that Audi A4 as we know it. In saying goodbye to the ‘B9’ generation A4 that launched in 2015, we welcome the Audi RS4 Competition Plus. 

It is the most hardcore example of the breed yet, sitting lower to the floor with hard-edged gear changes, lightweight wheels and snuggly bucket seats. You can also get it in swoopy RS5 Sportback guise. 

Audi is only bringing 75 units of each down under as a swan song for the B9 generation RS4 and RS5 before the even-numbered model moves into its all-electric future.

As we’ll go on to discover, these two special models see the A4 and A5 bow out in style.

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.
