• Not a cheap car to run
• Performance models worse still
• You get great enjoyment, though

The Mercedes-Benz S-Class Coupe sits in insurance group 50A and emits a significant amount of CO2 so this isn’t going to be a cheap car to run.

The S 500’s claimed fuel economy is 33.2mpg (though we saw just 18mpg during our time with the car). Fortunately,  it does sport a relatively large fuel tank of 80 litres with a further eight in reserve; if you manage to get close to Mercedes’ figures you can expect a range of over 600 miles per fill-up.

However, the S 63’s figure is a lowly 28.0mpg and the S 65 is 23.7mpg on average, but we did manage 21mpg in the latter on a long drive back from Germany without trying.

The rate of depreciation of the S-Class Coupe is inversely proportional to the cost of the car, meaning S 500 fares best and S 65 loses a terrific amount of money rather quickly.

The CO2 emissions the Mercedes-Benz S-Class Coupe produces range from 197g/km for an S 500 Coupe with the smallest 19-inch alloys to 279g/km for an S 65 on 20-inchers.

• Company’s reputation improved…
• …but there’s a lot to go wrong

While Mercedes-Benz reliability in general has improved markedly over recent years, there’s no escaping the sheer amount to go wrong on the S-Class Coupe.

But with that said, the only major recalls so far for the whole S-Class range have been to do with the stop/start system. Considering how many cars the firm has sold, that’s not bad going at all.
