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.

2026 Mercedes-Benz CLA-Class Summary

Mercedes-Benz has shifted its CLA compact coupe-style sedan from support player to headline act with the introduction of this all-new, third-generation version.

It exemplifies the German giant’s multi-powertrain approach with an expansion of the local line-up from two pure-combustion variants to a five-model range comprising three hybrid and two pure-electric options.       

CarsGuide was invited to sample the hybrid version of the newcomer (the EVs arrive in July), so stay with us to see if this sleek four-door is your kind of premium European compact sedan.
