The 2013 North American International Auto Show also called Detroit Auto Show starts today and will run until the 27th of January. This year’s Detroit auto show, which opens Monday, has a decidedly “green” theme. Green as in the color of money, that is. Upbeat Detroit auto show will also feature introduction of 50 new vehicles. Also, BMW will show its new 4-series cars, Lexus will introduce its IS saloon, and Infiniti will unveil the Q50, which analysts say will be the next G37 saloon.

Also on view will be the potent 2014 BMW M6 Gran Coupe, a sporty four-door with a twin-turbo 560-horsepower V8 that hits dealers this summer, and the 2014 Bentley Continental GT Speed Convertible, from Volkswagen AG’s British Uber-luxury brand. The soft-top Bentley, which goes on sale in late summer, claims to be “the world’s fastest convertible,” thanks to a 616-horsepower 12-cylinder engine that pushes the all-wheel-drive two-door to a top speed of 202 miles per hour.
