CHEVROLET CORVETTE: The 2014 model is the first all-new version of the iconic sports car in nine years. It has a dramatic styling that picks up cues from the 1963 Sting Ray and newer Corvettes. GM promised it would perform better than the current model yet will get better gas mileage. The two-seater arrives at showrooms in the fall. A 6.2-liter small-block V-8 with 450 horsepower takes the car from zero to 60 mph in under four seconds.
JEEP GRAND CHEROKEE DIESEL: The top-selling Grand Cherokee is making the jump to diesel power. It marks the first major expansion into diesel in the U.S. by a mainstream SUV maker, showing the potential for boosting power and fuel economy. The SUV's 3.0-liter, EcoDiesel V-6 engine promises 240 horsepower and the ability to tow up to 7,400 pounds. It's expected to get 21 mpg in the city and 30 mpg on the highway in 4x2 models, and 20 mpg city and 28 mpg highway for 4x4 models.
VOLKSWAGEN CROSSBLUE: Volkswagen may be getting into the midsize SUV market. It rolled out a concept SUV called the CrossBlue at the show. It would be a first in the U.S. market: a plug-in hybrid SUV with a diesel engine and two electric motors. In electric mode, it would get the equivalent of 89 miles per gallon, a measurement reached by estimating the energy it uses. In hybrid mode, it would get an estimated 35 mpg. VW will decide whether to make the vehicle in the next few months, based partly on reaction of show visitors.
