![]() I was suprised about the 22mpg from the ford.i originally put it done to sitting in traffic? do you have lots of hills you drive up? altho i do tend to crusie a bit more with the roof off as i like the fresh air and i like the feelling of my hair blowing in the wind.I refuse to chase it though!!!!!!!! to be honest i have really noticed much differenc in feul with the roof on or off.so i would assume it to be about correct. a soft top has drag with the roof up like any normal car.the only difference is when you remove the roof you get significant air turbulance generated where the roof should be, but that will only be a small amount greater than the drag generated from the roof being in place. if it was 20% worse you would cover a fifth less miles per tank which would prevent anyone buying them i think.10% maybe more realistic but i would still think that is on the high side.leaving the windows down on a saloon etc would create a an airbrake which would significantly affect the cleanliness of the car through the air. I wrote to merc as one of my collegues asked and i didnt know. ![]() i think the drag factor of the new shape is the same if i remember the wording.in fact it tells you what it is with the roof off somewhere.but i will have slung that out with the post. I achieved the above results with it switched OFF. One more thing, dont forget that the default setting for the Aircon is ON. Is this because the drag is increased somehow? I'm intrigued by a pervious post implying that the car uses more fuel with the top down, especially as the top was one of the reasons I bought the car. At 25 mpg that means I can cover another 70 miles or so before I conk out. The tank takes 53 Ltrs so that means when the light is on and I am half way down the lighted section I have something like 13 Ltrs (2.8 Gall) still in the tank. This time when I switched on, the gauge went all the way to the top. Then I continued to squirt the nozzle a few more times and managed to put in around 3 more Ltrs before it obviously wasn't going to take any more. This time I left the nozzle in until it cut out, this took 43 Ltrs, more or less the same as last time. To my alarm, it dropped a quarter of a tank in the next 42 miles! The next quarter took around 100 miles, and then it continued to drop until I reached the same point at which I had previously filled up (about halfway down the illuminated bit). ![]() When I switched on, the gauge went up to a fraction below the full mark. The first time I filled up, I just left the nozzle in until it cut out, then stopped at that. The fuel gauge however is very confusing. My driving style is mixed, sometimes I glide along, sometimes I floor it if I'm fed up with the (slow) driver in front and I get the opportunity. I have just calculated my mpg after a normal week of driving to work and back (around 50 miles per day mainly urban) and I find I am getting around 25/26 mpg. I am in my second week of ownership of a Jan 2000 slk230. So unless you have wedged your car in first gear we need further info. on the other hand it did 42mpg on A roads to blackpool and back.once!Īnd with a 1001 miles in a week around scotland it averaged 33mpg for the whole trip. and with real booting around the dales you could see of course would do less if you took it to a track and wrung its neck. it dropped to around 26mpg in heavy traffic. The subaru wrx i had, is not a economy engine and would easily reach 30mpg in normal driving. or maybes you have a fuel leak in the system. So give us more info on your driving style/conditons and what does the book say? You may need to give it a run up a smooth a road at 50ish for a few miles to generate whether the car is running fuel too rich for some reason. Unless you are really driving badly you should exceed that by a fair number of miles.anywhere above 25mpg-30mpg should cover urban driving from hard to smooth.īut it really depends on your exact driving conditions.lots of sitting in traffic or real slow creeping forward will lower you mpg but only beacsue you are not driving at fuel efficient speeds.to be honest, with the 230k you could almost see 18mpg on a track day.
