"Our strategy [at first] is to focus on efficient fundamentals, on the traditional vehicle and trying to get improvements on aerodynamics, mass reduction, rolling resistance, and getting electrical loads off the vehicle. … we are not going to see history repeat itself, meaning you are not going to see one dominant fuel for the next 100 years like we have seen in the past, its going to be a variety of fuels... incorporating bio-fuels, whether it is ethanol or bio-diesel, then we look at gaseous fuels either CNG or LPG, and then we move into the electrified side of the equation focusing on hybrids, pure electrics, and then eventually moving onto fuel-cell type technologies.
