".......Meanwhile, GM will be phasing in the hybrid gas-electric system, a fuel-saving powertrain option. In the spring of 2006, the Saturn VUE, and in 2007, the Chevrolet Malibu will get GM's Belt Alternator Starter (BAS) hybrid system coupled to a CVT, which will get an estimated fuel-economy improvement of 12-15 percent.
Mid-year in 2007 and soon after in comparably sized pickup trucks, GM's full-size SUVs will be offered with the Advanced Hybrid System II mated to a Vortec 5300 V-8 with Displacement on Demand. This combination will achieve a 25-35 percent fuel-economy improvement.
These changes are just the beginning of what will be a revolution in powertrain development. Various estimates suggest that by 2020, the conventional gasoline engine will be well on its way to being phased out, replaced ultimately by hydrogen-driven fuel cell systems. "
