2025 Audi A3 Summary

Can a hatchback still be a fun and fashionable way to get around when the SUV has become such a status trend?

The facelifted Audi A3 certainly makes a case for it.

The refreshed 2025 A3 is, as Audi puts it, more competitive than before when it comes to not only value but also, you might agree, style.

Last year, before the update even arrived, the A3 sold almost as well as its Volkswagen Golf corporate sibling. In fact, it’s Audi’s third most popular model behind the Q3 and Q5 SUVs.

It’s also third in its segment of ‘Small cars under $40,000’, behind only the MG4 electric car and, you guessed it, the VW Golf.

As such, it also outsells its actual closest rivals the BMW 1 Series and Mercedes-Benz A-Class, both of which are close to the A3 on price.

Now that it’s been given a bit more razzle dazzle, let’s see if the A3 can keep that momentum going.

2018 Infiniti Q50 Summary

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?

Verdict

Closing in on $60,000 for a small car isn’t cheap. Ask a car dealer and they might even say the hatchback is a good way to get someone into a showroom to eventually look at an SUV.

But I reckon you’d be doing the A3 a disservice to count it out. It’s always been one of those cars that does everything well, and with this current facelift manages to keep its practicality without becoming boring.

It looks good on the outside, it’s smart on the inside and it’s fun to drive while remaining sensible. Even if you get it in bright yellow.

Verdict

The Q50 Red Sport is a premium sedan that's great value, with a cracker of an engine. While Infiniti has improved the ride and steering, it still feels to me that the engine is too powerful for the wheels and chassis to handle. But if you're looking for something of an untamed beast, this car could be for you. Just don't say we didn't warn you.
