Like the automotive professionals at TheCarConnection.com, most reviewers find the on-road handling of the 2008 Cadillac SRX above reproach, but better when accompanied by the expensive Magnetic Ride Control feature.
A 5-speed automatic couples with a 260-hp, 3.6-liter V-6 in the base SRX. The duo offers ordinary acceleration and average fuel economy. We prefer the upgrade: a 320-hp 4.6-liter V-8. This year, it gains a 6-speed automatic. It's capable of much more impressive acceleration of about 6.5 seconds to 60 mph, but gas mileage isn't great.
Car and Driver thinks the base engine is "merely adequate." Autoblog says with either engine, the SRX puts out "smooth operation and responsiveness.". Edmunds likes the combination of the V-8 and the automatic, for its strong acceleration" but thinks the V-6 offers enough power for most. MyRide.com notes the six-speed transmission as shifting "smoothly at all times."
With either rear-wheel or all-wheel drive, the 4,000-pound-plus SRX gets low fuel economy: 13/20 mpg for V-8 models, only 15/22 mpg for the V-6, rear-drive model. The V-6 impresses ConsumerGuide since it uses "regular-grade gas," though Cadillac recommends "premium for the V8."
The SRX's magnetic shocks are an option, and ConsumerGuide thinks they're nearly essential. Without them, the SRX undergoes "lots of bounding" they report, "even on mildly rippled pavement." Autoblog calls the SRX "nothing short of excellent." "Steering feel is light at first," Kelley Blue Book says, but the vehicle is "easy to park." Car and Driver calls it "a sports car among SUVs."
