- 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.
Estimated fuel cost per year
|Fuel type||Pence per litre||Estimated cost per year *|
|Unleaded||128p||£1,763 - £3,063 *|
* 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.

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.
