The upgraded 5.1 surround sound system delivered an immersive audio experience with a robust baseline, although we did notice a lack of clarity and separation when playing music that mixed high and low ranges on XM's classical channel.
Our SRX was motivated by the base-level 255-horsepower V-6 engine, which handled the SRX's 4,000lb-plus bulk adequately around the city, and gave it adequate pickup on the freeway, albeit with a whining sound track. As maximum torque is reached at 2,800rpm, the SRX feels nippy in urban situations, but mid- to high end performance is more sedate. For those willing to spend an extra $6,000 to haul the family around with a bit more gusto, Cadillac offers the option of a Northstar V8 engine, which puts an extra 65 horses in the stable. SRX Drivers can take the five-speed transmission into their own hands thanks to the SRX's Driver Shift Control, which is activated by a flip of the shifter to the right and enables clutchless manual shifting.
Our tester came with the Performance Package, which gave it a limited slip differential; Michelin all-season tires; alloy wheels; Xenon, High-Intensity Discharge headlamps; and a headlamp washer system. As an additional $1,650 option, our car also came with Magnetic Ride Control, a system that uses a magnetic coil to regulate the flow of magnetically charged damper fluid to stiffen or soften the suspension response. In practice, the SRX coasts over uneven roads with the minimal amount of jarring transferred into the cabin. Throwing the car into sharp turns results in the expected body roll and pulling up to a sharp stop caused the cabin to lunge forward.
Fuel economy for the 2007 Cadillac SRX is rated by the EPA at 16mpg city/ 24mpg highway. Our observed economy over 317 miles of mixed city and (mainly bumper-to-bumper) highway driving gave a pretty dismal overall average gas mileage of 15.5mpg. The 2007 Cadillac SRX comes with a four-star frontal-impact rating and a five-star side-impact rating. Each SRX comes with six air bags as standard, including frontal- and side-impact airbags for driver and front passenger and side curtain airbags for first- and second-row passengers. Active safety systems include ABS, Stabilitrack, traction control, and a limited-slip differential. An LED-based rear ultrasonic parking sensor is an elegant and cheap alternative to a back-up camera, although the latter would have been nice to help maneuver the SRX's rear end when parallel parking.
Potential buyers of the SRX are likely to find the number of options packages bewildering. Our tester came with the V-6 premium luxury collection package for a whopping $7,150 extra. For this, we got all of the goodies from a variety of other lesser packages including the Performance package (limited slip differential, Michelin all-season tires, alloy wheels, Xenon, High-Intensity Discharge headlamps, and a headlamp washer system); the Luxury package (rear cargo area storage system, Universal Home Remote, wood trim, upgraded six-disc in-dash CD changer, tire pressure monitor and auto-reticulating air filter); and the Premium Seating package (heated driver and front passenger seats, driver and front passenger power lumbar control, eight-way power front passenger seat adjuster, outside heated power-adjustable and driver-side auto-dimming mirrors); as well as power-adjustable pedals, DVD-based navigation, and the 5.1 surround system.
The 2007 Cadillac SRX is a car for those who want some upscale trimmings to their family hauler. An impressive array of optional cabin tech makes the SRX a wired ride, and a number of unique interior design elements such as the UltraView roof, and the tiered seating mean that the cabin comfort wealth is shared with those in the rear. Competitors to the SRX include the Mercedes-Benz R350, the Chrysler Pacifica, and the Mazda CX7.
