Study focuses on reducing battery costs for plug-ins and hybrid vehicles

I just read some news about a study conducted by the Aluminum Association and Ricardo, a technical research outfit, that states using high strength, low weight aluminum over heavier steel structures for plug-in electric and hybrid cars can cut vehical price by reducing the battery energy requirements and associated costs. The purpose of the study was to evaluate the impact of vehicle weight reductions on electric vehicle performance, range, and battery size. The study also tested the role of vehicle mass on regenerative braking.

It listed a few car models that support the study's findings: They are Tesla Motor's Roadster, Fisker Automotive's luxury vehicle, and Bright Automotive's van. (I've never heard of these brands.) All are using lightweight aluminum platforms for their vehicles.
