Buick has bestowed a clean-sheet redesign upon its three-row Enclave SUV, and it's scheduled to reach dealers towards the end of the summer. Power comes from a new turbocharged 2.5 liter inline-four, which produces more than the old V6 at 328 hp and 326 lb-ft of torque. Elsewhere, the new Enclave receives an overhauled exterior and a more upscale interior with a wide curved display and available Super Cruise hands-free driving.
