Mercedes AMG GT (2014-2022) review – MPG and running costs
AMG’s engine has proven to be solid over the years, but running costs will be higher than a comparable 911
Strangely, all GT variants including Coupe, Roadster, GT C and GT R have an identical 22.2mpg combined rating on the WLTP cycle. Drive with restraint and these numbers will be achievable too, given the comparatively low-strung nature of the M178 compared to the 600bhp-plus applications in larger and heavier AMG models.
All models also have similar 290g/km CO2 ratings give or take one or two grams, which puts it in the same top road tax bracket as a Jaguar F-Type R and crucially, most Porsche 911s. A three-year unlimited warranty along with service intervals of 12,500 miles or every 12 months, makes the AMG GT a fairly easy to live with ownership proposition.
