Hobbiniho Posted January 22, 2011 Report Share Posted January 22, 2011 A lot of cars do have trip computers, which will give an indication of the MPG, but a lot of them are not 100% accurate, (citation needed?) as your indication of 999.9 MPG proves. My indication of 999.9 mpg proves what? That if you're travelling down a steep hill and not needing to accelerate, your car is merely ticking over and so using very little fuel?no if you are travelling down a hill in gear and not touching the accelerator if you have a modern car then you wil use absolutely no fuel at all hence why your mpg figure maxes out, on my leon the gauge just goes blank Quote Link to comment Share on other sites More sharing options...

Graeme_Storey Posted January 22, 2011 Report Share Posted January 22, 2011 Hobbiniho is correct. If you completely back off the throttle on many modern cars, the engine stops using any fuel at all, and is kept turning entirely by the momentum of the vehicle. I am not sure, but I think AUDI pioneered the technology. In other words, as long as you leave the car in car with the clutch in its normal position, the car keeps the engine turning when you take your foot right off the throttle (when 'coasting' downhill, or approaching a stop), and therefore you use no fuel at all in those circumstances. As soon as you dissengage the drivetrain (by depressing the clutch for instance), or touch the throttle then fuel is fed again to the engine and you never notice the difference. If you are stationary, with the engine turning, there is a small amount of fuel being used to keep the engine ticking over. Modern engine management systems are very complex and extremely clever. The stop/start technology is a different thing again. Quote Link to comment Share on other sites More sharing options...

Graeme_Storey Posted January 22, 2011 Report Share Posted January 22, 2011 ^^ Cheers for that GS - but what is classed as a "modern" car? Not sure what the technology is called, or who uses it, but maybe someone can help with a list. Only heard of it in the last 4 years or so.
