GM: Eight-Speeds on the Way

General Motors isn't giving away any of the specifics just yet, but it does have a seven- and even an eight-speed automatic transmission tucked away in its product development cycle, according to thecarconnection.com

Jim Lanzon, executive director of GM Powertrain's Transmission Engineering, acknowledged last week GM is looking at the transmissions that have begun showing up on luxury models such as the BMW M5.

"I can't give away any new product news but we're looking at everything," he said.

One of the issues GM is wrestling with now is whether a seven- or eight-speed transmission will produce the kind of gains in fuel economy that would justify the cost of engineering them into a vehicle, Lanzon said.
