Unchanged from the 2014 version, the SRX is back this year with very modern lines. Although it’s the same size as some of GM’s crossovers, the SRX has a platform all its own. There’s a dynamic 3.6L V6 engine purring under the hood, paired with a six-speed automatic transmission and optional all-wheel drive. The luxurious passenger compartment abounds with gadgets and driving aides.
