3.0 out of 5

Considering the GLE's size, fuel economy isn't too bad. It naturally performs better than the bulkier GL but maintenance costs remain typically Mercedes – in other words, pricey.

Mercedes GLE MPG & CO2

No large SUV will ever be truly economical, but the GLE tries its best to remain competitive with its closest rivals for efficiency.

The 350d returns a respectable fuel economy figure of 36.7mpg with CO2 emissions of 204g/km, but with rivals such as the (faster) BMW X5 3.0d M Sport offering 45mpg and 162g/km of CO2 the GLE really could do better. Oddly, the emissions for the GLE fall when this model is fitted with the larger 21-inch alloy wheels – dropping to 199g/km.

The GLE costs £140 per year to tax after the initial CO2-weighted payment at time of registration and as it has a list price of over £40,000 it is also subject to a yearly surcharge of £310, payable for five years. That'll bring your yearly bill to £450 for the five years following the first year's CO2-weighted payment.

Insurance group

The GLE 350d falls into group 45 for insurance purposes so will likely attract high premiums.


Mercedes provides a warranty that covers you for unlimited miles during the first three years of owning the car. It's a pretty standard affair that other German manufacturers offer, too.


Mercedes offers fixed-price servicing plans that can be paid up front in one go or spread over monthly instalments.
