My chart - 2010 Mercedes C200 CDI diesel estate, manual gearbox



Hi,

this is my first post here. I have been building my own chart since I bought this car (2010 Mercedes C200 CDI diesel estate, manual gearbox). What I am presenting is a series of values I sometimes gather during my highway trips. Each point represents 50 km (30 miles) of travel. Some trips have 250km, other are shorter (say, 50km) and therefore longer trips results have a bigger weight on the definition of the regression curve (made with Excel with standard parameters). Speeds are retrieved from the computer, which is very accurate in this respect. MPG data are also from the computer, which is, in average, 6% optimistic in relation to tank fill data. The car is absolutely stock and is using Michelin Energy Saver 205/55 R 16. I live in Portugal, so please apologize my English!

Obrigado, fcporto.

Are you using imperial (English) gallons or American gallons in your graph?

MetroMPG, thanks for the Portuguese salute
All data are US gallons, since I found people here use it more often.

fcporto, you really get 55 mpg at 65 mph with only lrr tires and hypermiling?

I looked at the .png you posted 'Benz C200 CDI mpg vs speed.png' and it is impressive if true. 65 miles a gallon at 55 miles an hour! 45 miles a gallon at 78 miles an hour! Am I reading it right? Is it possible you still had a kph / kpg issue in your data that you and the rest of us haven't seen? Heck of a car if this data is true. Any advice for when to shift to get the best mileage e.g. mid point of each gear, etc.

A youtube video (which I cannot post because I have no posts) seems to confirm the potential of the car. The title is '2010 Mercedes Benz C200 CDI Fuel Consumption Test'.

EDIT: video posted by admin




It doesn't appear that the C200 is available in the States....how much does one cost in Europe?

Hi Calry,

yes, I think I have made the right calculations to convert my original data (l/100km) to MPG (US)! Anyway, I am posting two of my photos of the car's computer display (no I am not, I am not allowed to due to low post count, sorry!!!). The car is indeed very economical, you can also check this youtube video also (also not allowed... but you can browse on Youtube with this expression "mercedes c200 cdi road eater" and it will be the first on the retrieved list).
The runs I used to calculate this data are long (between 50 and 300km) so these values could be improved in shorter distances (less traffic, flatter roads). The roads I used are seldom flat, so this involves some coasting in neutral in descents, but all data were taken between points with the same geographical altitude (usually, sea level).
Prices of this car in Europe vary, because of different tax incidence between countries. Over here, a similarly specified car would cost around 45000 , but I guess it would be cheaper in Spain or France, for example.
Similar cars like the BMW 318d or the Audi A4 2.0 TDI yield very similar results. Diesel engines are very frugal! Mine is the estate version, so the 4 door saloon, lighter and more aerodynamical, will be even better.
