Stylish, agile, and quiet, the Cadillac SRX is a competitive choice among upscale compact SUVs. The interior is richly appointed and nicely detailed. Updated for 2012 with a more powerful V6 that replaced both previously offered engines, this version of the SRX delivered slightly improved acceleration and fuel economy. Despite the added power, it still felt sluggish and underpowered in everyday driving, especially compared to rival luxury SUVs.
