During the General Motors press conference at the North American International Auto Show, it was announced that two fuel efficient Chevrolets will hit North America in 2011—The Chevrolet Spark mini-car and the seven-seater Orlanda multi-purpose compact vehicle.

The Chevrolet Spark was formerly introduced as the Chevrolet Beat Concept at the New York Auto Show in 2007. While most of the Beat’s concept was adapted, the implementation of larger windows is the most notable change. The fog lamps, headlights, and grille have been changed; the front has been altered to appear less sporty; and the Spark also looks as if it has been raised higher off the ground.

“Chevrolet Spark will bring great style, roominess and versatility to the segment of extremely fuel-efficient small cars in the U.S.,” Troy Clarke, president of GM North America, said. “The decision to add the Spark to Chevrolet’s portfolio reflects the brand’s commitment to being a fuel efficiency leader in the country.” The full production form of the Chevrolet Spark will be shown in March 2009 at the Geneva Auto Show. Europe will get the first glimpse of its sales in 2010.

On the other hand, Chevrolet Orlando is a sports-utility, family van and wagon rolled into one, which was recently revealed at the Paris Auto Show. It will join fellow Chevrolet models in U.S. showrooms sometime in 2011.

Chevrolet is confident that both cars will get a 40 mpg. North America Chevrolet Vice President Ed Peper is convinced that these small Chevys will make a big impact in the market particularly to those who are adamant in their demand for fuel efficiency, vehicle functionality and aesthetics.
