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.

2018 Nissan 370Z Summary

Road testing the Nissan 370Z in 2011, I noted it was getting on. Yes, the rear-wheel drive two-seater had been given a design freshen up and a bigger engine a couple of years prior, but the 350Z it was based on had hit the local market way back in 2003. And it wasn't unreasonable to expect replacement or retirement in the not-too-distant future.

Okay, so that was seven years ago, which means if you (like many) consider the 370Z to be an update of the 350Z (the transition happening in 2009), this car has been on sale for 15 years straight. Can you imagine Apple trying to sell any one product without entirely reinventing it for that long?

You might say that makes it a modern classic; so good it's only required an occasional touch up to keep it on the Sports Car Most Wanted list. And in recent years, a consistent average of 30 Aussies a month have slotted a shiny new 370Z in their driveway.

But a less-charitable type will tell you time waits for no car, and with arch rival Toyota about to lob a Supra-shaped hand grenade over the parapet, this enduring campaigner is under the pump.

So, Nissan's reached into its bag of tricks and given the 370Z yet another cosmetic tszuj-up and added a high-performance clutch to the manual version.

Is it enough to keep Nissan's eternal Z-car flame burning?

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

It's hard not to be ageist when it comes to the current Nissan Zed, because 15 years in market (nine if we're generous) is a lengthy stretch in anyone's book. But somehow the 370Z is more than the sum of its parts. It has fantastic front-engine/rear-drive balance, an increasingly rare atmo engine, and a beautiful manual 'box. The value equation is decent, and it's nicely put together. Just don't expect to be dazzled with the latest safety, driver-assist and multimedia technology.
