Mercedes A-Class dimensions
All the figures you need including the Mercedes A-Class boot size, plus length, width and interior dimensions

Despite being replaced by an all-new Mercedes A-Class, this previous-generation car is still in demand, thanks to its popular design and high specification.
it's also a little more compact than the new car, which might be an advantage when parking, but does have an effect on the amount of passenger and boot space.
To see whether the A-Class is the right size for you, scroll down for dimensions, luggage space, towing capabilities and more.
There are also full details of the car in our Used Mercedes A-Class buying guide.
Mercedes A-Class dimensions: exterior
The formula for a family hatchback is fairly standard and the Mercedes A-Class doesn’t break the mould. It’s short enough for a standard parking space and well under 2m (6ft 7in) wide - excluding he side mirrors - making it narrow enough for tight multi-storey car parks.
The wheelbase is the distance between the front and back wheels - usually the bigger this is, the more interior space you have.

Mercedes A-Class boot space
Mercedes sells the A-Class as a premium hatchback, marketing it as having an upmarket interior, German engineering and more style than its rivals. But its heavily styled design compromises the amount of luggage space in the car. The 342-litre boot is 38 litres smaller than the alternative Audi A3 Sportback, while a Peugeot 308 offers 128 litres more than the Mercedes.
Even when you fold down the seats, the space in the Mercedes lags behind the average for family hatchbacks. The A-Class’ boot opening is also smaller than its rivals, making it trickier to load with bulky items.

Boot space with seats down | 1157 litres | Smaller than average |
Mercedes A-Class dimensions: interior
The interior of the Mercedes A-Class can feel a bit cramped because of its low roof, but there’s actually a good amount of headroom for taller passengers in the front and back. However, the car isn’t as spacious as the Audi A3 Sportback.

Mercedes A-Class towing capacity
If you’re looking for a towcar, then the Mercedes A-Class is unlikely to be it. You’ll more likely want a heavier vehicle that can pull greater loads. However, if you do decide to hitch a trailer or small caravan to your family hatchback, then the A-Class is little different to other cars in its class. Depending on the model, you’ll be able to tow between 685 and 750kg. This rises to 1200 to 1500kg if you’re pulling a trailer or caravan that's fitted with brakes.

Mercedes A-Class weight
Lighter cars tend to be more efficient and nimble to drive, but the A-Class is one of the heavier hatchbacks on the market, with even the lightest coming close to 1400kg.
This is its kerbweight, a measurement that gives you an estimation of how heavy the car will be when you’re driving it, because it includes a virtually full fuel tank, as well as the weight of a driver and luggage

Mercedes A-Class fuel tank capacity
Buy a diesel A-Class and the tank should hold enough fuel to take you at least 600 miles between fill-ups, even if fuel economy is far below the official figures.
Petrol-powered A-Classes use considerably more fuel, so you’re unlikely to get more than 500 miles from a tank. Four-wheel drive versions - called 4 Matic - are the thirstiest models, so have tanks that are six litres larger.

Mercedes A-Class turning circle
In common with most family hatchbacks, the Mercedes A-Class needs an area that's 11m wide to turn around without the need for a three-point turn.
