DETROIT - General Motors will produce a 7.5-liter V-12 engine to be used in future Cadillacs and will launch a family of overhead-cam, high output V-6 engines.

GM also is revamping its pushrod V-6 engine family to include displacements of up to 3.9 liters and equipping the engines with fuel-saving cylinder deactivation technology, the automaker said Friday, Oct. 4, during a press event at its proving grounds in Milford, Mich.

Another addition to the automaker'* portfolio is a six-speed, rear-wheel-drive automatic transmission that will go into production in 2005.

The powertrain changes will enable GM to reduce emissions and improve fuel economy of future vehicles while offering higher performance.

Cadillac was the last GM division to offer a V-12, back in the 1930s. The coming V-12 is a new design, GM said. It will have an aluminum block and cylinder heads, double overhead cam-shafts and four valves per cylinder.

GM said the V-12 would produce significantly more than 500 hp but would not be more specific. Production volumes will be limited to fewer than 5,000 units a year, said Thomas Stephens, group vice president of GM Powertrain. He would not say whether the engine will be built at a GM plant or by an outside contractor. A 7.5-liter V-12 concept engine in the Cadillac Cien concept car was rated at 750 hp.

The V-12 was designed to fit in the same space as the V-8 engines GM uses in full-sized trucks and sport-utilities, Stephens said. But it won't fit in the engine bay of the upcoming Cadillac XLR roadster, he said.

The new overhead-cam V-6 engine family will have displacements ranging from 2.8 liters to 3.8 liters, aluminum blocks and cylinder heads and four valves per cylinder. GM said the first engine from the family will be a 3.6-liter V-6 that makes 255 hp and 250 pounds-feet of torque through technologies such as variable valve timing. It did not disclose when the engine will be introduced or in which vehicle.

The first of the revamped pushrod V-6 engines, using cylinder deactivation technology, will be a 3.5-liter unit in the redesigned Chevrolet Malibu, which goes on sale next year. The engine will run on only three cylinders when power demands are light, such as cruising at highway speeds.

I already know of ONE Caddy NorthStar V8 FWD engine with twin turbos that pushes 1200 HP! As for the article, I don't like the idea of cylinder deactivation in the least, simply put it means if a problem arises it puts the car in "LIMP" mode or just enough cylinbders running to get you off the road! This Technology does save the engine though but does have it bugs too!
