Executive Summary

Hybrids, plug-in hybrids, and battery electrics are conservatively estimated to reach a 5 percent national

car park by 2030. Drastic increases in the price of gasoline resulting from oil shocks or major shifts in

national energy and environmental policy, however, may push Electric Vehicles (EV) quickly beyond this

small share. Should such critical changes occur, EVs will be poised to move beyond their current niche to

gain wider scale acceptance and integration into transportation and energy infrastructure.

EV battery technology has not improved to the degree needed to achieve the same range mobility as

conventionally fueled vehicles. Electric powertrain hybridization and incorporation of regenerative

systems such as braking and flywheels are steadily, but only incrementally, improving EV fuel efficiency

and range performance. New Corporate Average Fuel Economy (CAFE) regulations in the next decade

may ŘNJƛǾŜ ǘƘŜ άƭƛƎƘǘ-ǿŜƛƎƘǘƛƴƎέ ƻNJ ŘƻǿƴǎƛȊƛƴƎ ƻŦ ǎƻƳŜ ǾŜƘƛŎƭŜ categories to achieve more aggressive

fuel economy requirements, especially absent a breakthrough in vehicle battery technology. Light-

weighting for battery electrics may be critical. Studies indicate that if primary vehicle mass is reduced

between 40-59percent, battery size and cost may be cut by nearly half without reductions in

performance.

Currently a number of automobile manufacturers are considering use of higher cost composite materials

and other strategies to reduce the weight and improve the mobility range and performance of EVs.

Light-weight vehicles may be more fuel efficient, but it remains to be seen whether they will be able to

afford as much protection for occupants in the event of a crash. To prepare for larger scale production

of electric vehicles,
