Mercedes GLA SUV - MPG, running costs & CO2
The Mercedes GLA range offers conventional petrol and diesel engines, plus a plug-in hybrid
GLA buyers can choose between three petrol engines and two diesels, with fuel consumption spanning from 36mpg to just over 50mpg; reasonable figures for a small SUV, if nothing groundbreaking.
Two high-performance AMG versions are also tempting but cost significantly more to run. Those looking to save fuel or reduce their company-car tax bills should look at the GLA 250 e plug-in hybrid. Thanks to a 15.6kWh battery pack and electric motor, this will be able to drive around 34 miles before the 1.3-litre petrol engine is required.
Mercedes GLA MPG & CO2
The entry-level GLA 180 and GLA 200 both use a 1.3-litre turbo petrol engine that's designed for efficiency but has to work fairly hard to lug around an SUV, so manage up to 42mpg. The GLA 250 gets a larger 2.0-litre petrol with more power and fuel-efficiency drops to 37.2mpg.
Switch to diesel, and the GLA 200 d with front-wheel drive can return up to 52.3mpg. Impressively, this figure only drops by around 2mpg with 4MATIC four-wheel drive fitted because the system is clever enough to only drive all four wheels when extra traction is needed. The range-topping GLA 220d 4MATIC uses the same engine but with more power and returns up to 49.6mpg.
CO2 tailpipe emissions span from 140g/km for the GLA 220 d to just over 170g/km for the GLA 250. If you're a company-car driver, and that sounds on the high side, there's also the GLA 250 e plug-in hybrid to consider. Thanks to an electric motor and 13.5kWh battery pack, this can drive for up to 37 miles without using any petrol. This results in official efficiency figures of more than 180mpg and 32g/km of CO2, radically reducing running costs for a significant swathe of buyers.
Fitted with 2.0-litre turbocharged petrol engines and four-wheel drive, the GLA 35 and 45 S performance versions will be the most costly to drive. Fuel economy of up to 34.5mpg for the 35 doesn't appear too ruinous but is likely to be hard to match in reality. This drops to 29.7mpg for more powerful 45 S, while CO2 emissions of over 180g/km put both hot GLAs firmly in the top BiK band for business drivers.
Insurance groups for the latest GLA haven't been announced yet, but regular versions should span groups between 20-30 out of 50, putting them in the same ballpark as rival SUVs. The AMG versions will be a different story, with insurance groups of around 40 making them amongst the most expensive small SUVs to cover.
Every Mercedes model has a three-year, unlimited mileage warranty that's identical to BMW's and slightly more generous than the 60,000-mile policy from Audi and Volkswagen. There's also up to 30 years of European breakdown cover, so long as you maintain the car's service schedule with Mercedes.
Mercedes servicing isn't the cheapest but customers have the option of paying for maintenance in monthly instalments.
