Buying a £100,000+ car doesn’t normally suggest it’ll be cheap to own, but Mercedes-AMG GT Coupe running costs are more palatable than you might expect. This is where downsizing really plays its part, since economy and efficiency of this 4.0-litre turbocharged V8 is legions ahead of the large capacity V8 engines from AMGs of old.

Choose the standard GT and officially it’ll achieve 30.4mpg, with CO2 emissions of 216gkm, while the 48bhp more powerful AMG GT S returns just 0.4mpg less and emits only 3g/km more (so it’s in the same tax bracket). Driven accordingly briskly though, those numbers are going to be closer to 20mpg than 30mpg.

In terms of insurance all sit in the top bracket, though the more powerful GT S will likely attract a larger annual premium.

Servicing needs to be carried out at one of the 52 Mercedes-AMG Performance Centres. 

There’s actually little difference between models when it comes to Mercedes-AMG GT Coupe CO2 emissions, as they use the same engine, just in different states of tune.

Opt for the base-spec GT and it puts out 216g/km of CO2. That’s not too far off the slightly less potent Porsche 911 Carrera S with PDK gearbox, which emits 205g/km.

At the other end of the scale, the GT R emits 259g/km, which is exactly the same as the similarly mad Jaguar F-Type SVR. 

A brief internet search shows some owners have suffered issues with the oil system, transmission failures and even engine problems. While we suspect some of this is down to usage, the reality is that the GT is a fairly highly strung sports car and will require diligent servicing and maintenance.
