Even after almost a decade on the market, the large Enclave remains a competitive three-row SUV. We liked its firm, comfortable ride and secure handling. The cabin is quiet, the interior is nicely finished, and the seats are comfortable. But the Enclave is beginning to show its age through some of the outdated controls and limited feature content. The 3.6-liter V6 engine and six-speed automatic transmission are smooth and unobtrusive, but the engine feels taxed and at times the powertrain has to work hard to move this large SUV. We got a paltry 15 mpg overall in our tests. Adults can fit in the roomy third row, a plus. Forward-collision and lane-departure warning systems are available.
