Consider this an open invitation to get on the plug-in hybrid bandwagon. Plug-in hybrids, for those not in the know, are hybrids whose batteries can be recharged by the grid. By running in electric-only mode as much as possible, emissions are reduced and efficiencies gained.
The other week, I visited Prof. Andrew Frank at UC Davis, the popularly acclaimed father of the plug-in hybrid. Impressive stuff.
Among the many vehicles his students have built, he's got a Chevy Equinox -- a smallish SUV -- retrofitted with a 1.6L engine with a continuously variable drive transmission and a lithium ion battery pack that holds about 15 kWh of juice. It can go 60 miles on battery-only, and 100 mpg in all-day driving conditions. If you recharged every night, it could go across the country on one tank of gasoline (runs on e85). Performance? 320 horsepower, 0-60 in 6.5 seconds (vs 9.5 sec stock).
The benefits of plugging in are many.
