Nissan is just now forming the Engineering group and Dodge and Toyota are making promises.

DETROIT, Jan 13 (Reuters) - Toyota Motor Corp President Katsuaki Watanabe said on Sunday the Japanese automaker will launch a diesel-powered Tundra pickup truck and Sequoia SUV in the United States soon, in an about-face to its hybrid-centred product strategy.
Toyota, which likely unseated General Motors Corp as the world's biggest automaker last year, has repeatedly hesitated to committing a diesel vehicle for the U.S. market, which is slowly warming to the fuel-efficient drivetrain, especially for use in larger vehicles.
"I am happy to confirm that a new clean-diesel V8 engine will be offered in both the Tundra and the Sequoia in the near future," Watanabe told a news conference at the North American International Auto Show.
The diesel vehicles were one way to meet new fuel economy regulations agreed by the U.S. Congress that require a fleet average of 35 miles per gallon by 2020, Watanabe said.
