Passenger & boot space
How it copes with people and clutter
To put it simply, the Mercedes-AMG A45 S is just as practical as any other Mercedes A Class. That means plenty of space up front for a couple of 6ft-plus adults – especially if you avoid the head room-stealing sunroof that comes on Plus versions – and decent oddment storage, too.
A couple of tall mates will fit in the back, but can expect to find their knees close to the front seatbacks and their heads near the roof. Still, the Audi RS3 isn’t much better. If you want a hot hatch and need to carry adults in the rear regularly, the generous rear leg room of the Civic Type R makes it a better bet, although it isn’t quite as fast.
