The CarGurus verdict

The fourth generation of Mercedes A-Class is its best yet, a stylish and well-made hatchback (and saloon), with some cutting-edge technology and a genuinely luxurious interior. It’s maybe not the most involving car of its type to drive, even when compared to cheaper cars like the Ford Focus or Volkswagen Golf, but that won’t matter to a large majority of its buyers.

It’s comfortable and economical, and there’s enough variety in the range to ensure that there’s a model to suit any one of a wide range of needs, from those wanting a monstrous hot hatch to those who prefer a plug-in hybrid, and everyone in between. It’s well worth checking out.

What is the Mercedes A-Class?

The A-Class has evolved over its life, from its introduction as an unusual hatchback-cum-MPV back in the 1990s to the smart, svelte hatchback and saloon you can buy today in this fourth-generation model.

Mercedes has tried hard to ensure that A-Class customers get the full Merc treatment, so its style is heavily inspired by larger models, and the interior too has a focus on very modern style and high quality materials.

Inside, you get an interior that mirrored Mercedes’ more expensive models when it was first launched. Despite a mid-life facelift in 2023, the interior has now started to fall behind the design aesthetic of newer models in the Mercedes line-up, although the tablet-like setup of infotainment system screens still looks impressive.

Rivals for this car include the BMW 1 Series and Audi A3, as well as higher spec versions of the VW Golf. Like the A3, the A-Class is available in five-door hatchback and four-door saloon body styles.

  • The current A-Class might seem like an entirely conventional (dare we even say generic) hatchback, that wasn't always the case. The original A-Class of 1997 was an entirely different kind of small car, with an innovative 'sandwich floor construction' that housed many of the car's major components in order to free up interior space.

  • The A250e plug-in hybrid promises, on paper at least, incredible fuel economy, but how much you get in the real world will depend how you use it. If you have somewhere to plug it in and keep the battery charged, and do mostly shorter journeys on purely electric power, then you can hardly use any petrol at all. But if you’re slogging up and down the motorway, or don’t plug it in to charge regularly, you’ll end up using the petrol engine to haul heavy electric equipment around and get a pretty poor mpg figure.
  • The A-Class Saloon looks, at first glance, very similar to the Mercedes CLA, and in fact the two are mechanically closely related. But while the Saloon lacks the coupe-like styling of the CLA, it has more practicality, with better rear headroom and more boot space than the hatchback A-Class. That said, if you want maximum practicality AND the bonus of style as well, check out the CLA Shooting Brake estate. Although be prepared to pay more for it.

  • If you want the best fuel economy: The A250e plug-in hybrid has an official fuel economy of up to 282mpg (WLTP), which is streets ahead of anything else in the range. But, how you drive it will depend how close you get to that figure. If a plug-in isn’t a realistic option for you, then an A180d will give you up to 62.8mpg.
  • If you’re a company car driver: The A250e hybrid has an official CO2 emissions figure as low as 23g/km (WLTP), which puts it dozens of Benefit in Kind tax brackets below other models in the range. And for regular users, it’s exempt from Vehicle Excise Duty. If that’s not an option, the diesel models are compliant with the latest RDE2 emissions regulations, which means they avoid the 4% diesel BIK surcharge.
  • If you want outright performance: The AMG A45 S is an absolute monster of a hot hatch, with 415bhp; power that rivals supercars from not that long ago. It’ll do the 0-62mph sprint in less than four seconds. For smiles and adrenaline in equal measure, this is the one to have.
  • If you want still-excellent performance but for considerably less money: The AMG A35 isn’t too far away from the A45 S in terms of fun, and it’s a darn sight cheaper. With 302bhp it’s far from lethargic, and it’s clinical in the way it deals with corners.
