The 3.0 L direct injection V6 is a smaller-displacement version of the 3.6 L, 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. Along with direct injection technology, the 3.0 L 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 rpm at constant highway speeds, while manual shift 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 2010 SRX will deliver excellent, balanced driving dynamics in all types of weather,” said Bob Reuter, global vehicle chief engineer. “The all-wheel-drive system with electronic limited slip effectively transfers torque not only from front to rear, but also along the rear axle. This system sets a new benchmark for all all-wheel-drive systems, giving the driver control and confidence on any road surface.”
Traction control is taken a step further on AWD models with the rear eLSD. In icy or wet conditions, the system can transfer up to 100 percent of torque to the wheel that has more grip. The eLSD also gives the driver enhanced control when cornering hard or completing a high-speed maneuver, such as a lane change, by momentarily applying more or less torque to either of the wheels to help the rear of the vehicle more closely follow the direction of the front wheels.
The suspension includes a real-time damping system in conjunction with AWD that adjusts shock damping rates in response to road conditions for a smooth ride quality.
SRX's safety features are designed to protect occupants before, during and after a crash. A strong body structure and chassis that absorbs crash energy is complemented by the use of martensitic steel in the fully enclosed rocker sections. Martensitic steel is one of the strongest available and its use in the rockers helps protect against intrusion during a side-impact crash, while also maintaining the structure during front and rear crashes.
Additional safety features include standard head curtain side air bags, standard front seat-mounted pelvic/thorax side air bags, front safety belts with dual pretensioners and load limiters, rollover mitigation sensors, a pedal release system, trailer stability assist and OnStar.
The SRX was also designed to meet European pedestrian protection standards; and the front bumper is positioned for greater compatibility with car bumpers.
Production begins in the second quarter of 2009, with dealer availability shortly thereafter.
