Mercedes GLE review - MPG, CO2 and Running Costs

Expensive to buy and expensive to run – the Mercedes GLE is not a cheap SUV

Predictably, the 300 d will offer the lowest running costs, but the GLE won’t be a cheap car to run. Prices start from around £55,500, increasing to a not inconsiderable £64,500 for the 400 d, although the cost is offset by the standard kit, up to a point.

Compared with its predecessor, there are some incremental fuel economy improvements, with Mercedes improving the car’s aerodynamic properties in order to improve efficiency. These changes extend to revised door mirrors, redesigned rear lights, changes to the underside and aerodynamic wheels.

The result is a 300 d that will return between 33.6mpg and 39.2mpg, depending on the choice of wheels and optional extras. The 350 d drops to between 29.1mpg and 36.2mpg, while the 400 d could return 29.4mpg to 35.3mpg.

Thanks to mild hybrid technology, the six-cylinder GLE 450 petrol isn’t quite the inefficient monster you’d expect, although it’s by far the thirstiest in the range. Figures of between 26.2mpg and 32.5mpg might be achievable with a light foot, but we still expect this to be a niche seller in the UK.

With CO2 emissions ranging from 162-169g/km for the 300 d, to 191-214g/km for the 450 petrol, VED will take a chunk out of your household budget, especially when you factor in the £310 supplement for cars costing more than £40,000.

The first year rate for the diesel models is £830, with the petrol costing an eye-watering £1,240. All GLE models will then cost £450 a year for the next five years before dropping to the standard £140 rate for cars with a list price of less than £40,000.

Insurance groups

The Mercedes GLE is not a cheap car to insure, with even the entry-level 300 d slotting into group 44. Things get more costly as you progress through the range, with Premium and Premium Plus models moving up a group, with the 450 d sitting in groups 47 and 48.


Premium SUVs usually have strong residual values, but the GLE is decidedly average when compared to some models. Buyers can expect to lose around 50-53 per cent of the GLE’s list price in three years, but the more expensive G-Class has residuals in the 60 per cent region, while the slightly older Range Rover Sport is also slightly ahead of the new Mercedes.
