![]() ![]() At the Feb. 20, 1999 EV1 Club meeting, Geoff Sommer unveiled a surprise EV1 "accessory" project he'd been working on. This is a trunk-mounted, twin jet engine subsystem (for model planes) meant to assist the EV1 when cruising on the freeway, creating a unique kind of hybrid vehicle. Here's his tour of his "e-jet" car for those who missed the meeting...
I prop the trunk lid open (rather than buy a new lid &
cut holes in it) mostly because of the no-modification
clause of the lease. Disadvantages include higher drag
and the fear that one day I'll forget to open the trunk
before firing up!! Benefits of the propped-open trunk
include less concern about foreign object damage ("bug
strikes") to the engines, and less worry about people
vandalizing the exhaust nozzles when parked. And I
didn't have to worry about fabricating inlets.
The engines provide 85 lb of thrust, enough to cruise at 67 mph on the level if my calculations are right. Mileage should be about 4 mpg, which gives a range of about 90 miles/tankful. Before you recoil in horror, that's actually incredibly good for a jet-powered car, and is only made possible by the EV1's efficiency. Anyway, I'm not advocating this for the masses - if I had my druthers, I'd use a small, non-recuperated turbogenerator, which could be quiet, clean, and get about 15 mpg instead: with a deadweight penalty of maybe 20 lbs with no fuel. Which is the OPPOSITE DIRECTION from that taken by automakers currently working on hybrids. Their hybrid approach cripples the EV. Mine doesn't.
