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 BMW I4 Summary

BMW has been incredibly smart with its electric vehicle (EV) offerings in Australia to date.

Ever since the Fringe Benefits Tax (FBT) exemption was introduced for novated lease buyers of EVs under the Luxury Car Tax (LCT) threshold, the German brand strategically introduced versions of its EVs that qualify.

The BMW i4 eDrive35 electric liftback, which is based on the locally defunct 4 Series Gran Coupe, is one of these cars.

It recently received a mid-life update that brought more range and features, while remaining under the LCT threshold for fuel-efficient vehicles.

However, the plot thickens. BMW is soon set to launch its new i3 electric sedan which is based on the company’s Neue Klasse dedicated electric architecture.

BMW hasn’t given the i4 an official production end date, however overseas reports indicate it’ll end as soon as next year to make way for the new i3.

Should you hold out for this new-generation car, or does the i4 still hold up? Read on to find out.
