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.

2021 Audi S8 Summary

Big sedans are not in vogue at the moment and huge luxury sedans were on the way down before the humble Commodore and Falcon departed the upper end of the sales charts. The Germans, who have always done a spectacular job of these flagship sedans, cheerfully persist with these cars.

Absolutely loaded with fascinating technology that bleeds its way down to the more mainstream models, they represent the zenith of the brand's innovation and style. The A8 is certainly that.

What it isn't, is particularly sporty, but after two years since its launch, V8 power has reached the fourth-generation super-sedan to deliver the latest iteration of the iconic S8.

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 S8's existence is a source of joy for me because it's not a huge SUV. Yes, it's a huge sedan but it's a reminder that the technological flagship is alive and well, at least in Germany. And the important thing about these cars is the way the toys filter down through the rest of the range. That used to take years but we're seeing this cool stuff a lot more quickly, right down to the A1.

The S8 punches, and punches hard in this rarefied part of an already shrunken section of the market - the twin-turbo V8 matches its German rivals, it's lighter and it's as well-stacked as any of the three. What it doesn't do, however, is shout about itself the way the other two do. It's the incognito choice.
