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.

2020 Lexus RC Summary

If it wasn’t for this review appearing on your screen right now, would you have even remembered the Lexus RC was a thing?

At the time of writing, the RC is actually the fifth most popular model in its sports car segment. Yep, only the two-door versions of the Mercedes-Benz C-Class and E-Class, and BMW 4 Series and Z4 sell better.

So, why is the RC seemingly invisible? But more importantly, does it deserve to be? Let’s test the RC 350 F Sport to find out.

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

If you’re a buyer that thinks with their head, the RC 350 F Sport is the obvious choice when compared to its direct rivals.

After all, it looks great (at least to these eyes), feels luxurious in more ways than one, and is unrivalled when considering value-for-money.

But, if you think with your heart instead, it’s clear it is isn’t on the same level dynamically and therefore doesn’t feel as sporty to drive as its name suggests.

So, don’t let its sports car classification fool you, the RC 350 F Sport is more of a grand tourer, or a comfortable cruiser, to be precise, and an underrated one at that.
