Car Forum / Mercedes-Benz Cars / March 2005MPG tips
When it comes to gas mileage, what is the ideal speed for highway driving in a Mercedes? Also, what are some good tips to improve mileage? (In addition to the usual things like no hard acceleration, etc). Thanks! > When it comes to gas mileage, what is the ideal speed for highway > driving in a Mercedes?

Make sure tires are properly inflated and all filters in good shape. cp Keep your car/boot (trunk) clear of unnecessary loads. Apparently every 100 kg add a litre per hundred km.

Thanks! 95km/h in highest gear (Driving km/h gives much more mileage;-) Takes 9 liters/ 100 km nearly independent of engine but on open windows and roofs. << Miscellaneous`Units` Convert[1/(9 Liter/(100 1000 Meter)), Mile/Gallon] 26.134927578497134 *Mile/Gallon Yes and don't change the speed. Even modest accelaration nearly doubles the hold consumption level. With a pressure of 37 lbs/inch^2 you will gain some additional 10%. Good for another 10% is a surfing board on the roof. No joke! -- Roland Franzius Forget all the other tips, I'm just going to put a surfboard on the roof! How far is the beach?

Also, what are some good tips to improve mileage? - of course keep air restistance down, no roof rack with skis, bikes or surfboards, - don?t push the engine to high rev/m before it is varm and smoothly running, - let it run on an even speed (rv/m), some additionals depend on the make you drive, - lower the suspension, - set the car in comfort mode - use distronic, radar dependent, speed control, as much as it is possible to do safely, We usually get between 9 l to 10.1 l /100 km from our E500T. Would most probably get more if we disconnected, phone, navigation, music, and most important the AC, whid takes a lot of energy to run. Per If your fuel economy suffers from using electronics (i.e radio, Phone, GPS, etc), then you have some serious problems in the car. The alternator turns all the time, only the AC should put a load on the car and cause an economy drop. You can cruise all day long with the Radio and GPS on, it will not affect the milage. > If your fuel economy suffers from using electronics (i.e radio, Phone, > GPS, etc), then you have some serious problems in the car.

Actually this is wrong (somewhat)... Although the alternator turns all the time, it has more resistance when it is needing more juice. Still this effect is negligible.

Nevertheless, when Mercedes claims it does 100 km on 8.4 - 8.6 litre, I am convinced they turn everything off that is not essential for keeping the car moving. In any case between 9 and 10 litres is not bad for a 5 litre V8. Per >When it comes to gas mileage, what is the ideal speed for >highway driving in a Mercedes? As slow as you can get away with, and at a constant speed. It's boring, but I can get really great milage in my E320 4-matic when I take it easy. During the latest price hikes here I kept to the speed limits and accellerated as cautiously as possible and saved a significant number of miles per dollar. (But that's boring, so I usually get around 21MPG...) Alternatively, if you want good mileage and excitement get the smallest engine available and floor it every chance you get. Also get the extended warranty. . As an American might put it, it ain't necessarily so... Or, why would some larger engines return similar mpgs to smaller ones?

The larger ones don't have to work as hard as the smaller ones... cp
