2012 Cadillac SRX gains the LFX

For 2012 Cadillac is dumping the smooth but overwhelmed 3.0 liter V6 and replacing it with the new LFX 308 horsepower V6 giving it a jump of 43 horsepower over the 2011 model. While the 308 horsepower is a good marketing bump, where consumers will feel the biggest change is in the torque rating. The outgoing 3.0 V6 produced just 223 lb-ft of torque at a lofty 5,100rpm. This meant that the driver would have to keep the engine rev higher even just for regular city driving. Indeed, the lack of torque was noted in our earlier review of the 2011 Cadillac SRX 3.0 and 2.8 Turbo. Cadillac remedies this deficiency by increasing torque output to 265 lb-ft and making that torque peak available at just 2,400 rpm. In city driving, this should make the SRX feel substantially faster than the 3.0 model.
In fact, this new torque rating pushes the SRX above the base engines of the BMW X3, Lexus RX350, Audi Q5 and Mercedes Benz GLK. The only luxury crossovers on the radar that offer more torque (Lincoln MKX and Acura MDX) make you rev the engine much higher to get it.
Along with the new engine, Cadillac is including a revised 6-speed automatic transmission with an Eco mode that lowers the rpm for each shift point, there by increasing fuel efficiency. With all of this increased power, fuel economy does get dinged by 1mpg in each rating to 17/24 cty/hwy for the front wheel drive model and 16/23 cty/hwy for the all wheel drive one. However, my guess is that with the availability of more torque at lower rpm, achiving those numbers will be more realistic.... something that couldn't be said for last year's model.
Cadillac claims that 71% of SRX buyers come from other brands. This has helped the SRX to take number 2 spot in the entry luxury crossover segment. With the above changes plus some other baubles and bright work, Cadillac is clear that they are not standing still.
