Mercedes GLE Coupe SUV - MPG, running costs & CO2
Both engines are thirsty and costly to insure
Regardless of which engine you choose, the Mercedes GLE Coupe is a big, heavy and fast SUV that will require deep pockets to run. A plug-in hybrid powertrain could make it cheaper to run day-to-day, but it's not yet known if the GLE Coupe will be benefit from this technology in the future.
Mercedes GLE Coupe MPG & CO2
Because of its niche status and high-performance billing, only six-cylinder petrol and diesel 3.0-litre engines are offered in the GLE Coupe, making it expensive to run. The GLE 400d diesel returns up to 38mpg and emits 195g/km of CO2, putting it in the highest company-car tax band. The less-powerful BMW X6 30d is slightly easier on the wallet, returning up to 46mpg.
Mercedes' mild-hybrid technology means the economy drop for the AMG GLE 53 version isn't as big as you might expect because it can coast at higher speeds when you ease off the accelerator, and the electric motor lends a hand under acceleration. Road tax for every GLE Coupe costs £465 in the first five renewal years, after which it reduces to £145 annually.
Expect high ratings when official groups are announced - even the entry-level standard GLE starts from group 44 out of 50.
All Mercedes models come with a standard three-year/unlimited mileage warranty in the UK. This can be extended for an extra cost, and matches the cover offered by BMW.
Don't expect Mercedes maintenance to be cheap, but there is at least a fixed-price system so you can check in advance how much you'll need to fork out for servicing and parts. Entering into a servicing deal for two, three or four services makes budgeting easier, as you can pay up front or monthly.
