2021 Audi RS5 Summary

Audi's A5 Coupe and Sportback have always been good looking cars. Yes, yes, beauty is in the eye of the beholder and all that, but seriously, just look at one and tell me it's not handsome.

Happily, the just-updated RS5 doesn't just build on the looks of its more sedate sibling, but on the performance, too, adding near-supercar speed to those supermodel looks.

Sounds like a pretty good match, right? Let's find out, shall we?

2025 Porsche 911 Summary

The icon is electric. Well, kind of.

This is the new Porsche 911 Carrera GTS, which ushers in a facelift for the brand’s most famous model — and it’s one that introduces a pretty major change.

That faint whistling you hear is most likely the distant wails of the Porsche purists, because this new 911 is now a hybrid.

Yes, the Carrera GTS features Porsche’s clever T-Hybrid engine, which is the brand’s take on electrifying the world’s most famous sports car.

It’s faster than the model it replaces, but it also fundamentally alters the formula that has made the 911 the world’s most iconic sports car.

The question is, does it alter it for the better?

Verdict

Good looking, good to drive, and good to simply sit in, the Audi RS5 range ticks plenty of premium boxes. Whether you can live with the practicality pitfalls of the Coupe is up to you, but if you can't, might I suggest taking a wander over to our RS4 Avant review?

Verdict

The more things change, the more they stay the same. The t-hybrid might be an entirely new propulsion system for the 911, but the net result is unchanged – power, poise and performance on tap.
