Reflecting the troubles of the automotive industry, the 2009 LA Auto Show was notable for the predominantly production-ready vehicles that were unveiled. Subaru and Mitsubishi revealed a couple of concept cars, but the majority of the other manufacturers were content to show upcoming vehicles ready for the showroom. Among the significant introductions were the Honda Accord Crosstour wagon and Acura ZDX hatchback. Over at the Mercedes-Benz stand, the new SLS sports car made its US debut. Toyota showed the revised Sienna and 4Runner, and the production version of the LF-A sports car. Buick brought back the popular Regal, now based closely on the Opel Insignia. BMW had the X6 M SUV and the 550i GT hatchback at their stand, and diesel versions of the 3-Series and X5 SUV. Rolls-Royce showed the new Ghost, which fits below the flagship Phantom. Nissan and Infiniti were notable in their absence, while Ferrari and Lamborghini neglected to appear as well. Despite a depressed market in the US, the LA Auto Show proves that automakers are still engineering new and innovative vehicles for their customers.
