Cadillac will debut the next-generation 2010 SRX Crossover next week at the North American International Auto Show in Detroit. This mid-size luxury crossover will feature a completely new design and more-efficient, high-technology engine choices. Fuel economy in the mid-20s on the highway is expected, but testing isn’t complete. The 2010 SRX seats five and can tow up to 3,500 pounds.
