Mercedes GLA (2014-2020) review - MPG, CO2 and Running Costs
The entry-level GLA is cheap to run, although it's more expensive to buy than its rivals
With a range of petrol engines being the only ones on offer until spring 2020, the Mercedes GLA has to give second best to its rivals for fuel efficiency. Under the latest WLTP test procedure, the GLA 180 manages up to 40.4mpg with the manual gearbox, while the auto-equipped version manages up to 39.2mpg. Go for the GLA 200, and these figures are 39.8mpg and 38.2mpg respectively. Move up to the 2.0-litre turbo petrol GLA 250, and it manages up to 35.8mpg, as it's pegged back by its standard-fit 4MATIC four-wheel drive and auto gearbox.
The best performing GLA models for fuel economy were the diesels. Whether you go for a manual or automatic gearbox, the front-wheel-drive Mercedes GLA 200 d is a cheap car to run, with a claimed 46.3mpg under the WLTP tests, while CO2 emissions stand at around 150g/km irrespective of whether you go for an automatic or manual.
The GLA 220 d features a more powerful version of the same engine, with 175bhp, but still shouldn’t break the bank when it comes to running costs. The official economy figure is quoted at 47.9mpg for the standard car and 47.1 for the AMG Line, although these figures are the older NEDC rates, and you're more likely to achieve the claimed WLTP figures in the GLA 200 d in the real world.
Insurance is another area in which the Mercedes is potentially going to be more expensive than its key competitors.
You’re looking at groups 22 and 23 for the GLA 180 and 200 models, while the GLA 250 sits in groups 28-30, depending on specification. However, entry-level versions of the Audi Q3 and BMW X1 start lower in the 20s and, with the exception of the flagship Audi RS Q3, neither rival exceeds insurance group 30, regardless of the model.
Mercedes has put a lot of work into improving its residual values lately, and small SUVs with premium badges are known for holding their money well, so the GLA will be less prone to depreciation than rivals.
