GM Moves Cautiously Forward on Green Cars

General Motors is working on greener cars powered by diesel-electric powerplants, but is taking a cautious route to market.

Like many other industries, the car business is currently grappling with the need to be more green. The impetus for change is coming from the usual twin-pronged cattleprod of legislation and market forces.

In Europe, the regulatory pressure comes from the European Commission, which has proposed laws capping average fuel consumption at 130g/km for a manufacturer’s entire fleet by 2012. The rules have yet to be set in stone, but only the smallest and most efficient cars on sale today slink under the proposed limits.

Car buyers, meanwhile, are sending a less than clear signal to the makers. Rising petrol prices at the pumps create some incentive to choose a more fuel efficient model, and some buyers are reacting as a result, but most consumers and business customers remain focused on other attributes. Big is still better, and speed still sells.


The Vue Green Line 2-mode Hybrid SUV will be powered by GM's 3.6L V-6 gas engine, with direct injection and variable valve timing, a nickel-metal hydride battery pack and two active cooled permanent magnet motors.

The vehicle utilizes a hybrid power train based on a 1500cc, 3-cylinder turbo charged diesel engine coupled with two high-efficiency permanent-magnet electric motors.

The driver of the Zytek dual-mode diesel hybrid can choose from standard or high regenerative braking and can also select one of three driving styles: Economy, Drive or Sport.
