Buick’s largest crossover is getting a first round of updates since a complete redesign for 2018. A new, monochromatic Sport Touring package adds another dimension to the Enclave’s styling. A few technologies make their debut including HD rear-view camera and HD surround view systems, plus a next-gen infotainment system with a new eight-inch touchscreen. A four-way power lumbar seat adjuster with massage is available, too. The 3.6-litre V6 does not change and still delivers 310 horsepower.
