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.

2019 Alfa Romeo 4C Summary

Nothing could’ve better prepared me for my drive in the 2019 Alfa Romeo 4C than a trip to Sydney’s Luna Park.

There’s a rollercoaster there called Wild Mouse - an old-school, single carriage coaster with no loop-the-loops, no high-tech trickery, and with each ride limited to just with two seats apiece.

The Wild Mouse throws you around with very little regard for your comfort, gently impinging your fear factor by making you consider the physics of what is happening underneath your backside.

It’s an unbridled adrenaline rush, and genuinely scary at times. You get off the ride thinking to yourself, “how the hell did I survive that?”.

The same can be said with this Italian sports car. It’s blisteringly quick, it’s superbly agile, it handles like it has rails attached to its underbody, and it could potentially do brown things to your underpants.

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

People might wonder if there’s a reason to buy an Alfa Romeo 4C. It has some great dollar-for-dollar competitors - the Alpine A110 does most of the things the Alfa does, but in a more polished way. And then there’s the Porsche 718 Cayman, which is a considerably more, well, considered option.

But there is no doubt the 4C stands alone, a sort-of cut-price alternative to a Maserati or Ferrari, and nearly as rare to spot on the road as those cars, too. And just like the rollercoaster at Luna Park, it’s the sort of car that’ll leave you wanting another go.
