Active Fuel Management
For the first time in many years, the engineers at Holden, GM's Down Under division, have cut the power of a V8 engine in the big Commodore sedan. The 6.0L V8 automatic transmission combination in the Commodore is now equipped with Active Fuel Management, GM's terminology for cylinder deactivation. The system allows four cylinders to be shut off at light load conditions. In the Commodore (which is sold in North America as the Pontiac G8) the power drops from 362 hp to 349 hp while combined fuel
Australia's Holden, a unit from General Motors, has announced a new badge for all vehicles that it equips with some sort of alternative fuel or gas-saving technology: ecoline. Holden faces a bit of an uphill climb when it comes to environmentally-friendly technology, as the marque is best known for its large, rear-wheel drive, V8-powered coupes, sedans and utes.

The powerplants span the gamut of technologies available today and include hybrids, traditional gasoline-powered engines, ethanol powerplants and everything in between. The claim to fame for every last one is better fuel economy, reduced emissions and more choice, the automaker says.
