Back in February, reports started circling that Cadillac would be doing away with the previous 3.0-liter V-6 and replacing it with the 3.6-liter V-6 in the 2012 SRX, and today, it's official: the 300-horsepower LFX engine will be available.

The larger V-6 adds 35 horsepower and 37 pound feet of torque (now up to 260 pound-feet) to the old V-6's figures, while still delivering similar fuel economy. The first of the new 3.6-liter SRXs will arrive at dealerships later this summer, but pricing won't be announced until closer to launch date.

Mechanically, the SRX will remain otherwise unchanged for the 2012 model year, but the new SRX will see standard Bluetooth phone connections on all models, additional door lock switches on the driver and passenger doors, a heated steering wheel on the higher-end packages, and a choice of new 20-inch machined-finish wheels, included in the performance and premium trim SRXs.
