Engineering plastics make inroads in EVs

07/25/2012

The impressive 351-km range of a high-performance electric car under development in Japan is credited to a unique "in-wheel" motor system and extensive use of lightweight materials according to project leader SIM-Drive Corp. (Kawasaki, Japan). These materials include several engineering plastics.

SIM-Drive is working with a team of 34 companies including DuPont (Wilmington, DE), Toray Industries (Tokyo), Bosch (Stuttgart, Germany) and Polyplastics (Tokyo), on the prototype SIM-WIL next-generation EV vehicle that features nearly 50 new technologies. It was unveiled in March this year.

The SIM-WIL's range is reportedly 30% farther than today's mass-produced EV vehicles. Yet it also delivers a maximum speed of 180 km/hr (110 mph), sports-car acceleration from 0-100 km/hr (0-60 mph) in 5.4 seconds, and offers a higher level of interior space and comfort....
