Audi A5 vs Infiniti Q50

What's the difference?

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.

The Infiniti Q50 Red Sport sedan really wants you to love it, and this latest version is doing its best to impress the heck out of you with its looks and features.

So much so that you'll take it home... and live with it, forever. And then there's that engine – armed with a formidable twin-turbo petrol V6, the Q50 Red Sport's outpowers all its rivals.

But then there's the BMW 340i which is not that much more expensive... and it's a BMW. And what about the Lexus IS 350? That's more like the Infiniti, but also more popular.

Oh, and don't forget that we when first met the Q50 Red Sport last year we didn't exactly get off on the right foot. The engine's formidable grunt seemed too much for the car to handle. Then there was the jiggly ride, and the steering wasn't great either unless you were in Sport + mode. It's all coming back now...

Perhaps the Q50 Red Sport had changed. This is the new one, and Infiniti had assured us it's a different car now.

Do we give it another chance? Of course, and we do, in a quick 48-hour test. So, has it changed? Is it better? Would we live with it forever?
