On to engines. In the petrol range, the entry-level A 180 variant is likely to be popular, featuring a 1.4-litre 136hp unit available with either 6-speed manual or 7G-DCT dual-clutch auto transmission. This same engine's offered in the A 200 with 163hp, which manages rest to 62mph (in the manual model) in 8.2s. Next up is the A 250, which uses a 2.0-litre petrol powerplant in a 224hp state of tune, manages rest to 62mph in 6.2s and is only offered with a 7G-DCT auto 'box. Mercedes also offers an A 250e petrol plug-in hybrid variant, which uses a 1.33-litre petrol engine mated to a 75kW electric motor linked to a 15.6kWh battery and offers 44 miles of WLTP-rated electrified driving range.
There are three diesel alternatives, all offered only as automatics. The first is the A 180d, which puts out 116hp and uses the 7G-DCT auto gearbox. Next up is the A 200d which has a 2.0-litre 150hp engine. Beyond that lies the top A 220d, which tunes the same unit up to 190hp. The A 200d and A 220 use an 8G-DCT auto. At the top of the range are the two Mercedes-AMG 2.0-litre petrol turbo hot hatch variants. There's the A 35 4MATIC which offers a potent 306hp. And the A 45 S 4MATIC+, which has 421hp.
What else do you need to know? Well the suspension is the usual torsion beam rear set-up on most models, but if you go for a variant with 4MATIC AWD, you'll get a more sophisticated multi-link rear set-up. The 'DYNAMIC SELECT' driving modes system is standard, as usual enabling you to tweak steering feel and throttle response. At extra cost, adjustable damping can be added into it. Some of the autonomous driving capability from larger Mercedes models has been built into this one, meaning that, in certain situations, you're a-Class, if appropriately equipped, will effectively be able to drive itself on dual carriageways at cruising speeds.
