The large, three-row Buick Enclave crossover is being treated to its first redesign in about a decade. The 2018 model promises improved fuel economy, increased interior space, and a technology smorgasbord. A 3.6-liter V6 teamed with a nine-speed automatic transmission sees output increase 14 hp to 302. Combined with a start/stop system, this powertrain should bolster efficiency over the 15 mpg we recorded with the outgoing model. This setup has a towing capacity of 5,000 pounds and is available in front-wheel drive or all-wheel drive. Buick says significant attention has been paid to quieting the cabin, and second- and third-row seats fold flat for loading cargo. Advanced safety features such as automatic emergency braking and forward-collision warning are available, though not on all of the trim levels. Full-speed AEB is available only on the top-level Avenir.
