XLhybrids systems are being installed on some of our company service vans.
This is an aftermarket installation which is advertised to take less than six hours to complete.
Braking recharges the battery for later use.
The cost is supposed to be less than 10K US dollars.
Currently available for Ford and Chevy vans.
When I have excess cash, I'd like to be the first on my block with a hybrid Toyhome.
