Mercedes GLA review - MPG, CO2 and running costs
The GLA petrol plug-in hybrid version is the most efficient choice, but make no mistake, running any Mercedes isn’t cheap.
Mercedes has given customers a choice of refined petrol and diesel engines for its smallest SUV, but for those seeking the lowest running costs, the GLA 250 e plug-in hybrid model should be at the top of the list.
Priced from around £40,000, the 250 e offers a claimed all-electric range of 37 miles, with combined fuel consumption of up to 201.8mpg. However, to achieve this impressive figure, you’ll need to ensure you keep the battery topped up and plug-in to recharge whenever possible. CO2 emissions of just 32g/km also mean there’s no first-year road tax to pay, while company car drivers will benefit from a BiK tax rate of just 11%.
Since the GLA was launched, Mercedes has also introduced the EQA. It’s a similar size and has many of the same styling cues as the GLA, and costs about as much as the plug-in hybrid too. The EQA manages up to 263 miles between charges and accelerates up to 62mph from a standstill in a reasonably brisk 8.9 seconds. Tax is free for private buyers and BiK stands at just 1% in 2021/22.
The petrol GLA 180 and 200 models both offer a maximum 42.8mpg on the combined cycle, with CO2 emissions from 151g/km. Opting for the more powerful GLA 250 means more time spent at the fuel station, as it only returns 37.2mpg. It’s CO2 emissions are also higher at 172g/km.
The diesel versions obviously perform better than their petrol counterparts in terms of economy - the 200 d achieves 52.3mpg, while the four-wheel-drive variant delivers a best of 50.4mpg. The 220 d is still reasonably competitive with a maximum of 49.6mpg, and CO2 emissions range from 140g/km to 151g/km.
The entry-level GLA 180 Sport is in insurance group 27, so premiums are going to be on the high side. The 250 petrol variant is in group 36, while the Mercedes-AMG cars occupy groups 41 to 44.
Equally, there’ll be no insurance bargains if you opt for an oil-burner, with the base 200 d Sport in group 31. The top-spec 220 d AMG Line Premium Plus sits in group 37.
You’d expect sound residual values from a premium manufacturer such as Mercedes, and the GLA performs reasonably well. Over an average ownership period of three-years and 36,000 miles, the GLA holds onto around 50% of its original value. However, the Volvo XC40 fares slightly better, with 55% of its list price retained over the same period.
