Summary


The Mercedes-Benz A-Class is a medium-sized hatchback and saloon model. The current generation was launched in the middle of 2018 and has quickly become one of the best-selling cars in the UK.

A saloon version joined the range in the middle of 2019, which has not been offered in previous generations. There is also a pair of hot-hatch performance model available called the Mercedes-AMG A 35 and the even-faster Mercedes-AMG A 45.

The Mercedes-Benz A-Class has received generally good scores from most UK media sources, with most rating the entry-level models slightly higher and performance-oriented titles slightly lower. Scores for the hatchback and saloon models are very similar, which is not surprising.

A facelifted A-Class range arrived in the UK in late 2022. It consists of minor visual and trim updates, as well as improvements to the car’s infotaiment system.

As of February 2024, the A-Class has an Expert Rating of A, with a score of 75%. That puts it towards the top end of the medium car class in our Expert Rating Index.

Green NCAP has tested two versions of the Mercedes-Benz A-Class to date – one petrol and one diesel. The petrol scored a creditable three stars, which is one of the best results seen for a fossil-fuel car, while the diesel was not far behind on two-and-a-half stars.

These scores only apply to the specific engines and gearboxes shown above. You can’t draw any conclusions about other models in the range.

Reliability rating

Reliability data provided exclusively for The Car Expert by MotorEasy

All data based on MotorEasy average workshop costs for extended car warranty claims

The Mercedes-Benz A-Class is higher than average in its reliability score, according to warranty data provided exclusively to The Car Expert by our partner MotorEasy. This score and data cover both the current A-Class and previous (pre-2018) models.

The average repair cost of more than £550 is rather average for a mid-sized car but considerably more than the cost of a used car warranty, which is worth bearing in mind.

The most commonly reported faults to date have been with the car’s electrical system, which is a relatively cheap fix at less than £300. However, there have been a reasonable number of claims for engine and gearbox faults, which have an average repair bill of around £1,000 and £2,000 respectively.

Running costs for the Mercedes-Benz A-Class are reasonable for the price of the vehicle, but more expensive than similarly-sized cars from other brands. This is based on data provided exclusively to The Car Expert by our commercial partner, Clear Vehicle Data.

Fuel consumption for petrol models is average, although diesels are better. The plug-in hybrid looks good on paper, but this is deceptive – every plug-in hybrid looks great in theory, but this is because of rubbish EU/UK government lab testing. You certainly won’t get 316 miles of driving from one gallon (4.5 litres) of fuel and a bit of electricity…

The battery range of the plug-in hybrid is surprisingly good, at 50 miles according to the official tests. That’s better than most plug-in hybrids, but you’ll still need to charge it almost daily to get best use out of the electric motor and battery. By comparison, an equivalent mid-size full EV would get more than 200 miles out of its battery so most households would only need to charge it once a week.

Scheduled servicing costs are quite good for the first five years, so you shouldn’t have to fork out too much for your annual service.
