ParkingWhere possible try to park facing downhill, and in spaces where you don't have to reverse in or out.

So I'll kick off with a few. I know some are obvious ParkingWhere possible try to park facing downhill, and in spaces where you don't have to reverse in or out.DrivingDon't brake. Well of course you are going to have to brake, but every time you do you are wasting energy and increasing your fuel consumption. Think ahead, get your foot of the gas sooner.Slowing downRemember the fuel pump cut-off. If you don't have a scanguage this is not obvious, but then you are decelerating don't dip the clutch and coast, keep the car in gear because the ECU turns off the fuel pump.

As a result, I'm lost confused. This is apply only to slowing down from a hill or does this include slowing down into lights when you got your foot on the brake as well? Sorry, but could you explain this a bit more for me? =/ Sorry!
I wonder what is more efficient - driving in, e.g., 5th gear at ~1500rpm, or 4th gear at ~1900rpm (same speed). In theory there shouldn't be any difference for fuel consumption, since in both cases you are moving the same mass having same overall resistance at the same speed. But it's only when we do not take into account at what RPM engine is most effective.If we are talking about 1.6 CRDI, I think that max torque is at ~1900. So it appears that it should be better to keep RPM close to this number (i.e. drive in 4th gear). But almost every "eco-driving" advice says "change gears as soon as possible". So I wonder if it's good advise...
Thats' what I usually do - let RPM climb to 2000-2500 then change gear.Also, one more point - if you drive at low speed (e.g. 20km/h), overall resistance is rather small and there is very little difference in fuel consumption if you keep RPM at 1500 or at 2000 (not much power is required to move the car). But things change when speed goes up, as air resistance is function of speed v3. Much more power is required to move the car...
I think more correctly air-resistance varies with the square of the velocity, not cube.
lol we have uber fuel efficent cars... i think we are doing enough!
