GM's Urban Car for China (continue)

GM Concept Car
2010 GM EN-V Concept

With the trunk-less EN-V, GM has jettisoned the traditional "three box" system and gasoline-fueled engine in place of a pure-electric minivehicle meant strictly for city driving. Five fit in the parking space needed for one conventional vehicle, says Kevin Wale, president and managing director for GM China Group.

"GM's vision with SAIC is petroleum-free, emission-free, accident-free and congestion-free," said Wale. "We think we can do that by combining the benefits of electricity and connectivity."

By 2040, GM says, there will be 1.2 billion cars on Earth, and 60 percent of humanity will be living in cities. For megacity countries like China, the explosion in use of conventional automobiles has already turned into a nightmare of smog, jammed roadways, and nonexistent parking.

The 1.5 meter by 1.5 meter (about 5 foot by 5 foot) EN-V appears to build on GM's earlier work with Segway Inc. in developing the PUMA, or Personal Urban Mobility and Accessibility, vehicle. It will use the same types of battery cells as the Segway and the same battery supplier, Valence Technology Inc., said Christopher Borroni-Bird, GM's director of advanced technology vehicle concepts.

With the EN-V, GM proposes to reconstruct the automobile's "DNA."

The EN-V's maximum speed of only 40 kilometers per hour (24 mph) — even now city roads average only 20 kilometers per hour (12 mph) and often less — and other high-tech features reduce the need for heavy, high-stress steel, bumpers, air bags and crumple zones, says Albano.

Apart from its diminutive size and light weight — 400 kilograms (880 pounds) including the passengers — the vehicle would offer drivers the option of "autonomous driving:" letting the car drive itself via an elaborate system of GPS systems, digital maps, roadway and vehicle sensors, cameras and other devices.

"None of this is beyond the technology that exists today," Wale says.
