Mercedes-Benz > E-class Coupe E 220d (194 Hp) Ficha técnica

I recently purchased my e220 bluetec coupe 2015 with 20k miles and very pleased with the car. Apart from the fuel economy my own click to click test combined motoring keeping within the speed limits returned 38.7 mpg. I complained to Marshalls Mercedes Preston Lancs, they kindly, under warranty did there own click to click test over 65 miles there return was an astonishing 64mpg with receipts for start and finish fuel and pics of the speedometer. The timing between the receipts was 1 and a half hours an average speed of 43mph The service manager assured me that the controlled test was extra urban within speed limits . Why can`t Mercedes and there franchised service depts. be honest and declare mpg figures on normal relaxed driving kept within speed limits. Very misleading and dishonest. Trading standard should be alerted. I was also told by the service manager not to trust the cars computer mpg readout. I do hope the speedometer is correct.

Well its 3 years since my first comment. I have kept spreadsheet log of fuel mileage click to click. no speeding offences driven the as you would any car within speed limits. 12334 miles 1491 litres 327 gallons £1832 cost per mile .149p The only way Marshalls could achieve 67mpg would be to leave it on a ramp free wheeling at 43 mph maybe disconnecting the aux belts. my motoring is mixed. Marshalls any comments other than you first comment 3 years ago "not to trust the instrument panel.
