How much does the Mercedes-Benz GLS cost to run?
- Diesel the best performer for fuel consumption
- Unlikely to be cheap to maintain
- Things like tyres will be expensive
The GLS 400 d is capable of 29.7-30.9mpg, according to Mercedes-Benz. As the engine is fairly effortless, this shouldn’t be too difficult to achieve if you take it easy.
These are the only figure available for now for cars arriving in the UK ahead of the rest of the range.
How eco-friendly is the Mercedes-Benz GLS?
Go for the GLS 400 d and CO2 emissions are rated at 208g/km. There are no figures as yet for upcoming GLS 450 and AMG GLS 63 variants, but you can certainly expect the hot AMG version won't be that kind to the environment.
However, the GLS 450 comes with what Mercedes calls EQ Boost. It's a 48v mild-hybrid system that not only boosts performance, but it also makes the car quicker and more efficient to start up and switch off when the engine is warm.
Is it reliable?
The GLS is covered by Merc’s standard three-year/60,000-mile warranty if anything goes wrong. The previous model was the subject of just one recall regarding the power steering, and no others. This latest GLS is all-new however, with new components shared with the latest GLE. There are a lot of systems to go wrong, but it all feels solidly put together and would have been tested thoroughly to put up with the rigours of life as a luxury SUV.

How much is it to insure?
Vehicle excise duty (VED) varies according to the CO2 emissions and the fuel type of the vehicle. For cars registered before 01 March 2001 it is based on engine size. For cars registered on or after 01 March 2001 the VED or road tax is based on the car's CO2 emissions.
