Mercedes-AMG GT review - MPG, CO2 and running costs

A high performance V8-engined sports car with a near six-figure price tag is never going to be cheap to run, but the GT gives you the image, sound and thrills of the spectacular SLS model for a lot less money.

The entry GT model emits 289g/km, with the GTC variant only slightly higher at 291g/km. Under WLTP testing procedures, all Mercedes-AMG GT cars are expected to achieve an average of around 22mpg, although you can expect this figure to drop significantly if you explore the full performance that's on tap.

Insurance groups

As with mpg and CO2 emissions, insurance costs for the AMG GT are extremely high. Every model sits in group 50, which is as high as it’s possible to get.

However, you can’t really single the Mercedes out in this area, as the majority of rivals at a similar price point and with equivalent levels of performance also sit right at the top end of the insurance scale, so it’s the same situation across the board.

Depreciation

Cars with a premium badge on the bonnet are usually off to a good start when it comes to used values and, while the AMG GT's stock has softened a little, it should still be worth around 50% of its original cost after three years. 

It’s worth bearing in mind how much it costs in the first place, though, as there’s more outright value to lose than with cheaper cars.
