Here are some of the new cars and experimental concept vehicles unveiled at the show:

— INFINITI Q60 CONCEPT: Infiniti is previewing the design of its upcoming Q60 coupe with a concept car unveiled Sunday evening. It's got sharper, more precise styling than the current Q60, along with a more aggressive grille and narrowed headlights. Under the hood will be Infiniti's new turbocharged 3.0-liter V6. This is no design study; Infinit says the Q60 that will go on sale next year will be strongly influenced by the Q60 concept. Nissan's luxury brand could use the boost. U.S. Infiniti sales have fallen over the last two years as the brand announced plans to revamp and rename its models and struggled with low quality rankings.

— BUICK CASCADA: General Motors is introducing the Cascada, a Buick version of a stylish Opel convertible from Europe. The four-seat Buick is the brand's first convertible in 25 years. It has an insulated soft top that can be opened in 17 seconds with the car traveling at up to 31 miles per hour. It also has a turbocharged 200 horsepower engine and a safety system that deploys rollover protection bars behind the rear seats if the car detects that a crash is possible. The car goes on sale during this year's first quarter.
