High tech development, market launch and retreat

Because its 1,175-pound pack of 27 advanced lead-acid (PbA) batteries - 26 propulsion, one for accessories - held a mere half-gallon of gasoline-equivalent energy, the production EV1 would have to be an incredibly efficient teardrop-shaped two-seater to achieve even barely acceptable range. Stretching it to accommodate four passengers would have reduced its already very modest range some 25 percent due to added weight and aero drag.

"The fundamental variables are mass, aerodynamics, rolling resistance, accessory loads and driveline efficiency," says Bob Purcell, who was our Advanced Technology Vehicles (ATV) Div. Executive Director. "So the exercise was to ensure that we would meet all customer requirements using the least possible energy in each of those areas."

When GM Vice Chairman Bob Lutz speaks, controversy usually follows closely behind. Unlike many high ranking executives Lutz often wanders off the defined script such as when he recently commented on global warming being a crock of .... I sure wouldn't want to be one of the PR handlers having to spin his words. In his latest chat with Detroit News columnist Manny Lopez, the electrification of vehicles was obviously front and center as it often is these days at GM. The EV1, of course, comes up and the accuracy of Lutz's claims will certainly seem open to debate. As recounted by Lutz via Lopez, GM tried and tried to find buyers for the EV1 but no matter how much they dropped the price, only about 800 people were willing to step forward. That was the reason for leasing the vehicles, according to Lutz. That statement seems highly dubious if EV1 fans are to be believed.

Certainly the market for the EV1 was extremely limited because of its practical limitations and the high cost, but it sure seems like more than 800 people were interested. Or maybe its a case of the hindsight that revealed there were actually 40 million people at Woodstock. Lopez and Lutz apparently also talked about how out of touch some (actually most, based on my own experience) people are with the realities of building a car. That's an area we try to address here on ABG regularly by discussing the technology that makes these modern machines go and what it takes to make it happen. One-off prototypes are easy to build but they aren't going to cut it when you have to meet modern customer and regulatory expectations. On a final note, Lutz revealed that the first Volt mule is now running with a lithium battery pack in it.
