The XC90 is a highly capable and competitive three-row SUV. Base models use a 250-hp, 2.0-liter four-cylinder turbo, offered with front- or all-wheel drive. We tested the T6 with its 316-hp, turbocharged and supercharged version. It delivers decent punch and returned 20 mpg overall. but has a raspy sound. A plug-in hybrid with an electric range of about 14 miles is available. All versions use an eight-speed automatic. Handling is commendable, but the ride is stiff, though the optional air suspension makes it more comfortable. The interior is quiet, plush, and modern, with supercomfortable seats. But audio, phone, and navigation functions are controlled through an unintuitive touch-screen infotainment system. Many electronic safety features are available.
