Mitsubishi
Too bad the Concept-RA has "concept" in the model name, because this sport coupe sounds like an incredible package. It has a 2.2L 4-cylinder diesel engine that makes more than 200 hp and 310 lb-ft of torque that's fed into the super-fast Twin Clutch SST automated manual transmission and then into the S-AWC all-wheel-drive system that's used in the Evolution X sedan. The Concept-RA also uses active steering and suspension dampening along with active yaw control and stability programming to keep the chassis glued to the road. How do we get on the waiting list?
Saturn
The Saturn Flextreme has also been seen on the auto show circuit wearing a Vauxhall/Opel badge, and it shares most of its drivetrain with the Chevy Volt concept. Regardless of its family history, the Saturn Flextreme is a diesel-powered electric hybrid that can travel up to 34 miles on just electric power. It also has two built-in Segway auto-gyroscopic electric scooters to increase the zero-emissions cool factor.

Toyota
Toyota Motor Company President Katsuaki Watanabe surprised some people by announcing that a clean diesel V-8 will be offered in both the Tundra and Sequoia "in the near future." The engine will probably be a variant of the 4.5L twin-turbo V-8 that's currently offered in the Land Cruiser overseas. That engine makes more than 260 hp, nearly 480 lb-ft of torque, is good for 22 mpg, and can push the big L200 from 0-62 mph in a respectable 8.2 seconds.
