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.

Making sense of autonomy Industry offers a range of sensors that will free humans from many tasks while also improving reliability, though devising strategies that meet demanding requirements without breaking the bank is no easy challenge. Life-cycle planning-Design and calibration for ultimate efficiency The ultimate power of Big Data technologies relies on the implementation of new strategies. Unlike a traditional engine calibration process, in which only calibration test data and model simulation data are used, multiple source data introduced into the adaptive engine calibration process contributes to efficiency and cost reduction. The complicated future of off-highway engines Developing an optimum engine is getting tricky now that the European Union has established a Stage V for off-highway engines, and the U.S. has not. What effect will this have on future engine designs?
