Mercedes GLE Coupe SUV (2015-2018) - MPG, running costs & CO2

The diesel engine returns the best fuel economy, but it’s not as efficient as a BMW X6

MPG, running costs & CO2 Rating

3.0 out of 5

In the UK we’re provided with a narrower GLE Coupe range than elsewhere in Europe, but we do get the GLE 350d version, which is the most economical model in the range. However, no model is what we’d call cheap to run.

Mercedes GLE Coupe MPG & CO2

The 3.0-litre diesel is no different mechanically to that in the regular GLE and returns up to 39.2mpg, with CO2 emissions of 187g/km, which means it sits in the top 37% Benefit-in-Kind (BiK) band for company-car drivers This may not seem unreasonable for a car of this bulk and power, but it is beaten by the equivalent BMW X6, which can return around 45mpg.

Unfortunately, there’s no option to buy the GLE Coupe in 2.0-litre 250d form – an engine that works very well in the regular GLE. There is one other engine that both versions of the GLE have in common, though: the range-topping 5.5-litre V8 in the AMG GLE 63.

Although the brochure states 23.7mpg as achievable in the V8, we suspect that few will ever see this in real life, such is the temptation of revelling in all that power. A return of 15mpg is rather more likely, and the AMG GLE 63 emits a huge 278g/km of CO2 as well, so it also sits in the top BiK band.

The middle ground is occupied by the AMG GLE 43, returning a far more palatable 30mpg, with CO2 emissions of 215g/km or 225 g/km, depending on whether 21- or 22-inch alloy wheels are fitted.
