Now THIS is innovation! It's not an engine that suffers from the serious inefficiencies of running at 20% throttle. It's an engine that runs at it's most efficient setting to do one thing: Recharge that battery.
What we need now are on/off engines built into the car and right-sized to be mostly on to recharge the battery during extended driving, but which run at their most efficient fuel COST to kW-hr ratio.
The 45 mpg Prius got it fairly right, but the 100 mpg (gas only) 300 mpg (electric only equivalent) Aptera NAILED it. Too bad consumers balked. Armed with one of those puppies, I could drive and see my son in California several times a year, for less than $200, and that includes one hotel stop on the way, and another on the way back!
Thing is, my 1979 VW Rabbit Diesel got 49 mpg on the highway, all day long. It's 10 gal tank would take me further than I'd want to drive! Just fill 'er up at the start of a long, cross-country trip, and about 8 hours later, do it again. I'd be done long before the second fillup came close to running empty.
So... How is it possible to achieve better efficiency from a 1979 vehicle that sat four people than we can achieve with a 2000+ era vehicle that's supposed to be cutting edge?
Why did the Aptera drop offline? No, really - what was really behind its demise?
Why was VW able to achieve a 214 mpg vehicle back in the mid-1970s on their European test track, yet such a vehicle has never seen the light of day?
