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 Lexus CT Summary

There are two ways to look at the Lexus CT200h; as either the cheapest model in the Japanese company’s range, or as a planet-saving hybrid.

Either way, the four-door, five-seat CT200h hatch – which has been updated for 2018 – differs from the rest of the Japanese luxury brand’s lineup for a number of different reasons.

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

The cheapest Lexus of them all isn’t chasing badge snobs with the CT200h as blatantly as Mercedes-Benz, BMW and Audi do with their entry level cars… but it’s perhaps not quite the Lexus you’d expect it to be.

It has a lovely front-of-cabin, for example, but there’s a lot of last-gen Prius in plain sight in the rear of the cabin.

The hybrid powertrain, too, is noble in concept, but the day-to-day reality is that it’s not as nice to drive, especially town to town, as a regular petrol-powered car of similar size.

The foot brake, silly multimedia joystick and odd gearshifter also spoilt the party a bit.

Empty nesters who are looking for a nice city runaround with a tinge of greenwash about it will love it… and if the current Prius is anything to go by, the next CT will be a very good thing indeed.
