Why Volt? After 48 months' development, the 2011 Chevrolet Volt has enetered series production. The pioneering "E-REV" is as important to the mobility industry as it is to GM. Creating the heart of Volt GM's battery requirements meant creating new state-of-the-art in-vehicle engery storage - and doing it in less than four years. Top GM and supplier engineers reveal how they did it. Engineering with maniacal focus A dedicated, cohesive team and a conservative engineering approach put this innovative vehicle into production at moon-shot speed. A unique electrified transaxle Hybrid or not? Definitions aside, what really matters is GM wisely leveraged its next-generation Two Mode propulsion technology to give Volt greater overall efficiency. Sweating the body details Extensive wind-tunnel work gave Volt a shape that's slicker than it looks. But engineers aren't happy with the curb weight.
