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.
