The 10-day-long Los Angeles Auto Show began Friday at the Los Angeles Convention Center, with more than a thousand cars on display, including concept and ecofriendly vehicles.

According to reports, the cars on exhibit this year include a wide range of luxury and high-performance vehicles. In fact, more than one-half of the models making their debuts are believed to be in the luxury and performance categories, which may indicate the recovery of sales of automobiles in these classifications, following a market slump in 2009 and associated economic crises.

Some of the luxury and high-performance automobiles at the show are the Audi R8 GT Spyder, Jaguar XKR-S convertible, BMW i3 and i8 electric and hybrid concepts, Mercedes-Benz SLS AMG Roadster and C-X16 concept, Cadillac XTS luxury sedan, and Porsche 911.

Luxury means peace of mind, quoted General Motors North America President Mark Reuss as saying while unveiling the charcoal-metallic-colored XTS. Luxury also means more power.

The Los Angeles Daily News estimated about 20 vehicles on display average 40 miles per gallon of gasoline, including the new five-door Chevrolet Spark, which offers 55.4 miles per gallon. In addition, the Ford Escape, Honda CR-V, and Mazda CX-5 are also making their debuts.

There are also a number of cars being unveiled in the electric-vehicle space, including the CODA sedan, Nissan Leaf, and BMW i3.

The Los Angeles Auto Show's run will continue until Nov. 27.
