I do a lot of coasting with my cars
It works better for gasoline stick shift cars than my diesel automatic car With stick shift i often get three untis of distance to one unit of acceleration typicaly on flat road I will accelerate to 60MPH and then coast back down to 40 MPH making the average speed about 45MPH In My SX 1400 Fiat Bravo car the differences are approx driving steady state ~40MPH best case is about ~43MPG Using coasting best case is about ~40MPG doing 60mph down to 40MPH average ~45MPH More normally I tend to do 70Mph coasting down to 50MPH and get 35MPG versus steady state 60MPH where MPG will be more like ~30MPGhods I still haven't figured why higher speed costing tends to be better than steady state driving at higher speeds and the opposite seems is true at lower speeds I suspect the gear ratios are the issues and am looking to convert the final drive to higher gear rate . Then I figure i can get 10% better MPG overall and better MPG with coasting methods across the full range Around town commutes costing increases the MPG ~25MPG to about ~30MPG its marginal stuff but still 5 MPG on 25 MPG in town driving is nearly 20% gain using coasting methods On the automatic it only coast at high speeds when it goes into the 3rd th gear not overdrive like 4th so is only coasting between 50 down to 30MPH with not a lot of noticeable saving from normal 40MPG when on the highway operating at speeds from 40 to 80MPH the MPG hardly changes much coasting on roads across flat plains where there is gentle undulations with gradual climbs and gradual down slopes seems to return better results to MPG than pure flat roads . Coasting in mountain roads with steep climbs and steep down slopes doesn't seem to work well as so much fuel is used climbing and the engine has to tick over to supply brakes and power for the down slope that it is all marginal stuff Ralf |

Then one day her dad drove me, her and the mom to a restaurant. If the speed limit was 35, he would speed up to 40, coast down to 30, and repeat. I've never suffered from motion sickness, but that was close! |

I'll settle for 10% of that mileage in a decent sized sedan like my Mazda 3.
Problem I'm having right now is I just got new tires. Quieter, smoother, less rolling resistance, better grip ... my average MPG just went down 3. |

All that work building that car and the best advice they can give to drivers is "if you have to slam on your brakes coming to a stop sign you're probably using too much fuel to get there" ? Duh.....no kidding. Someone figured that out decades ago. Problem is more than half of all drivers drive like that today. You will never retrain them to drive a car using this technology.
