General Motors will add a pushrod 3.9-liter V-6 engine to its lineup in the 2006 model year, the automaker said on Friday. The engine will be built at the automaker's Tonawanda, N.Y., engine plant.

The new V-6 and a 3.5-liter version using the same architecture will be equipped with GM's fuel-saving cylinder-deactivation technology that shuts down cylinders based on vehicle speed and engine load. GM says the system delivers an 8 percent gain in fuel economy.

GM is investing $300 million in the plant for new machinery and production lines. The upgrades are expected to be completed by the fourth quarter of 2004. The Tonawanda plant produces GM's 2.2-liter Ecotech four-cylinder; 3.1- and 3.4-liter V-6s; 8.1-liter V-8; 2.8-liter four-cylinder; and 3.5-liter five-cylinder engines. Employment is 3,340.

I don't know if I'd trust a system like that. If you had a V8 that was running on 4 cylinders, sure it would save fuel, but wouldn't it add a lot of powertrain loss, or "drag" to the system?

Sounds like the old Caddilace 8-6-4, I hope this one is better!

GM claims it is way better. We'll see, but I believe them. No room for serious mistakes right now for them. Even small mistakes actually.

Yes but it will work on half the cylinders only when cruising, etc. Only when LOAD is at low or constant form/intensity.

It was a flop before when Caddilac tried it.

That was back in 1981 folks. Give the guys the benefit of the doubt.
