GM presented the new 2010 Cadillac SRX Crossover, featuring a new design and more-efficient engine choices. The new SRX, a mid-sized luxury crossover, will debut at the North American International Auto Show in Detroit next week.
A new, 3.0L direct injected and E85 capable V6 engine is standard and a new, 2.8L turbocharged V6 is optional. Direct injection enables a 25% reduction in hydrocarbon emissions. Fuel economy in the mid-20s on the highway is expected, but testing isn’t yet complete.
The 260 hp (193 kW) 3.0L V6 is paired with a six-speed automatic transmission, and offers 221 lb-ft (300 Nm) of torque at 5600 rpm. The new direct-injected V6 engine is expected to raise the SRX’s standard power rating by 5 hp, while achieving an estimated 10-15% fuel economy improvement.
The 3.0L direct injection V6 is a smaller-displacement version of the 3.6L direct injection engine featured in the CTS sport sedan and named one of the world’s 10 Best Engines for 2009 by Ward’s Automotive. (Earlier post.) Along with direct injection technology, the 3.0-liter engine employs variable valve timing to optimize power and fuel efficiency and reduce emissions.
The Hydra-Matic 6T70 six-speed automatic transmission helps save fuel by lowering the engine’s revolutions per minute at constant highway speeds, while a manual shift lever control enables greater driver interaction when desired. The new SRX includes a driver-selectable “eco mode” that alters transmission shift points to maximize fuel economy.
The 2.8L turbo delivers 300 hp (224 kW) of power and 295 lb-ft (400 Nm of torque); it is paired with an AF40 Aisin Warner six-speed automatic transmission.
An available all-wheel-drive (AWD) system includes an electronic limited-slip differential (eLSD) that distributes torque as needed from side-to-side along the rear axle, in addition from the front to rear axle.
The new SRX will be available at European Cadillac dealerships in the fourth quarter of 2009.
