The Los Angeles Auto Show opens to the public tomorrow and one of the most anticipated cars is the 2013 Cadillac XTS. The sleek XTS features a 3.6L direct injection engine and advanced all-wheel drive system, marking a shift to more-efficient performance in a spacious luxury sedan. Sports Car Illustrated: says: The advanced 3.6L V-6, known by its “LFX” engine code, is rated at an estimated 300 horsepower (224 kW). Lightweight features help reduce overall weight for greater efficiency and a more favorable front-to-rear weight balance.. The LFX engine is matched with the Hydra-Matic 6T70 six-speed automatic transmission with tap-shift control. The XTS rides on a smart Haldex all-wheel-drive system – with an electronic limited-slip differential that splits torque between the rear wheels – complements an advanced HiPer Strut front suspension and standard Magnetic Ride Control real-time damping to give the XTS sure-footed, confident and comfortable ride and handling traits.
