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.
Estimated fuel cost per year
|Fuel type||Pence per litre||Estimated cost per year *|
|Unleaded||109p||£1,652 - £2,065 *|
* The estimated fuel cost figure is based on an annual mileage of 10,000 miles and is a guide to how much this model will cost in fuel each year. It's calculated using the model's average MPG (calculated from both town centre and motorway driving) and the average fuel price from around the country. Actual fuel costs will vary based on driving style and road conditions. Fuel prices are updated daily.

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.
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.
Highest and lowest CO2 emissions
|Engine||CO2 emissions||Road tax (12 months)|
|4.0 Petrol||216 g/km (Min)||£305 - £450|
|4.0 Petrol||259 g/km (Max)||£450 - £535|
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.
