GM engineer says dozens of issues must be resolved before vehicle rolls in 2010

TRAVERSE CITY, MICH.: Early versions of the Chevrolet Volt's battery packs are powerful enough to run the high-stakes rechargeable car, but dozens of issues remain before General Motors Corp. can start selling the revolutionary vehicle in 2010 as planned.
The Volt's chief engineer is on a tight schedule to figure out how the car will handle the batteries' weight, dissipate their heat and mechanically transfer their power to the wheels. That's not to mention the list of issues that have nothing to do with the car plugging in to the wall for recharging.
But the veteran GM engineer who was recruited from a GM post in Germany to run the high-profile project is driven by knowing the entire company's future could rest with it.
''At this point, there's nothing standing in our way of continuing to do what we said we're going to do,'' said Andrew Farah, 47, the Volt's chief engineer.
Work on the Volt, introduced as a concept car at the 2007 Detroit auto show, has taken on a more urgent pace with gasoline hovering near $4 per gallon and the U.S. auto market dramatically shifting from trucks to cars.
The car is designed to run on an electric motor powered by a battery pack. Drivers will recharge the vehicle from a standard home wall outlet.
The Volt will be able to travel 40 miles on a full charge, and a small gasoline engine will recharge the batteries to keep it rolling on longer trips. GM says the vehicle will get the equivalent of 150 miles per gallon.
But for now, as a new commercial airing during the Olympics touts the Volt as the pinnacle of GM's fuel economy improvements and hybrid lineup, Farah and hundreds of other engineers are working quickly to deal with the inevitable glitches from new technology.
They must figure out how to keep the battery cool and adjust the car's suspension so it performs well while carrying a 400-pound battery
pack.
''All those things result in lots of other mechanical parts and bits and pieces that have nothing to do with electrical energy,'' Farah said. ''So we've had some issues there.''
Simultaneously, other GM workers are testing batteries to make sure they last at least 10 years or 150,000 miles. It would cost more than $10,000 to replace them.
Still other workers are making the Volt more functional, giving it the room and feel of a regular car ''such that the vehicle is not just a battery on wheels,'' Farah said.
The early concept, a low-riding, sleek silver hatchback, was uncomfortable to sit in and not very functional, Farah said. The new five-door hatchback version more resembles a normal car, a little larger than a Honda Civic.
''It'll have a similar set of visual cues and some of the features that were on the concept car,'' Farah said.
