New standard features include LED headlights, LED taillights, rearview camera and rear park assist. The all-wheel-drive system is a twin-clutch design and is Buick’s first switchable AWD system. There are available high-tech features like Buick’s new QuietTuning system, a 360-degree view camera and ventilated front seats. Heated front seats are standard.
