At 45mph, with moderately careful driving, a 1990s Solectria Force could achieve 150 Wh/mi - 6.7 mi / kWh. Solectria claimed 137 Wh/mi or 7.3 mi/kWh, which is probably what James Worden could get. And that was a conventional steel-bodied Geo Metro. I've also done 160 Wh/mi (9.9 kWh / 100km or 6.25 mi / kWh) in a Dacia Spring at an average of about 60 km/h (37 mph). And that's only slightly more aero than a cinderblock. But as Bill pointed out, wind drag rises as the square of the speed. I'm too lazy to compute it, but the difference between 40 or 45mph and the Renault streamliner's 63mph average is pretty substantial. My question: why couldn't Renault do better than a 0.3 drag coefficient? Engineers know how; remember the slippery solar racers from the 1990s. My guess is that Renault were too focused on making the car pretty and exotic- looking. David Roden, EVDL moderator & general lackey To reach me, don't reply to this message; I won't get it.
