Parkers overall rating: 3.9 out of 5 3.9
  • Enough cabin space for four adults
  • Generous boot capacity now competitive with rivals
  • Easy-to-access Isofix points on outer rear seats

The lack of cabin space was a common complaint about the previous-generation A-Class, and is something that Mercedes has worked to improve in this model. Shoulder, elbow and headroom has been increased front and rear, and there’s now enough space for four average-sized adults.

Technically, it will even seat five, but the middle seat is best suited to children thanks to the chunky central tunnel robbing legroom. Legroom and headroom for the outer rear seats is ample for most, now, though. And certainly better than in the latest Audi A3.

Boot bigger than before but still lags behind VW Golf

Luggage room has grown to 370 litres in this A-Class, and although that's still shy of the 380 litres available in that latest A3 Sportback, BMW 1 Series and Volkswagen Golf, the squared shape of the boot in the Mercedes makes it very useable. Not only does it boast an extra 29 litres of storage space with the rear seats in place compared with the previous model, the load aperture is 20cm wider. This means it’s easier to get awkward, wide objects - such as pushchairs - inside; the lip should prove low enough for most, too.

For longer items, the rear seats fold down almost flat in a 40:20:40 split, while arch intrusion is kept to a minimum. The boot also contains power sockets and hooks for storing shopping bags.

One unnecessary irritation is that the oversized, one-piece rear headrests are fixed, not only dramatically reducing rear visibility but also making it impossible to fold the rear seats down unless the front seats are quite far forward.

If the front seats are anything other than close to the wheel, therefore, you’ll either have to slide the seats forward or tilt them forward to allow you to drop the rear ones.

Plenty of storage space

The A-Class has enough storage space for the needs of most drivers. Up front, the door pockets are a good size and there are two reasonably capacious cupholders in the centre console. The compartment under the armrest is fairly narrow but deep, while the glovebox is an average size. In the back, there are a couple of smaller door pockets, fold-out cupholders and twin air vents behind the front armrest. 

All cars come with a standard reversing camera, making it relatively easy to manoeuvre the A-Class into tight spots. It is 14mm wider than the previous-generation car however, so owners looking to upgrade their old A-Class should double check that the new one fits comfortably in their garage.

Mercedes-Benz A-Class safety

  • Five star Euro NCAP safety rating
  • A-Class boasts raft of accident-avoiding safety kit
  • Two easily accessible Isofix points fitted as standard

As we’ve come to expect from Mercedes, the A-Class is packed with what it calls Intelligent Drive systems designed to help the driver avoid potential accidents. The list of technology is comprehensive, and includes:

  • Active emergency brake assist – brakes the vehicle to a standstill within its lane if it detects no input on the steering wheel during a pre-defined time and after multiple visual and acoustic warnings
  • Active lane change assist – capable of automatically changing the vehicle’s lane when either of the indicators are activated
  • Active distance assist Distronic (adaptive cruise control) with active steering assist – maintains a set distance (and maximum speed) to the vehicle in front, while also providing in-lane active steering assist
  • Active blindspot assist – warns the driver of the presence of another vehicle in the car’s blindspots. Also capable of alerting the driver to vehicles and bicycles approaching from behind as they are about to open their door
  • Autonomous emergency braking
  • Active speed limit assist - automatically adjusts the adaptive cruise control speed with the help of the traffic sign recognition function

The Active lane change assist works well when using the adaptive cruise control, taking its time to check for traffic before making the manoeuvre. The active speed limit assist works with the cruise control but we found it to be quite abrupt when adjusting to speed changes - driving into a lower speed limit often resulted in the sudden application of the brakes, making for a less relaxed experience.

The same is true of some of the operation of some of the other safety systems. The active lane keeping is very aggressive, for example, and will tug hard on the brakes if you even try to pull out behind a car that's passed you without leaving enough room for the system's satisfaction. One you learn that the car is going to react like this you can account for it, but the first few times its intervention can come as quite a shock.

How many Isofix points are there?

There are two Isofix points fitted as standard on the outer rear seats of the A-Class. Easily accessible, parents shouldn’t have any trouble attaching the car seats - certainly the parents on the Parkers team have found them straightforward to use.

The A-Class scored a maximum five star rating from Euro NCAP when tested in late 2018, performing well in all categories.

Euro NCAP Rating – 5 stars

The Mercedes-Benz A-Class Hatchback was tested by Euro NCAP in 2018 and was awarded a 5 star overall rating. This overall rating is calculated from the following individual ratings:

5 star rating
Test 2018
Individual safety ratings
Adult Occupant: 96%
Child Occupant: 91%
Vulnerable Road Users: 92%
Safety Assist: 75%

Euro NCAP provides motoring consumers with a realistic and independent assessment of the safety performance of some of the most popular cars sold in Europe. The safety ratings are determined from a series of vehicle tests, designed and carried out by Euro NCAP. These tests represent, in a simplified way, important real life accident scenarios that could result in injured or killed car occupants or other road users.
