The Envision comes with only one available engine, a powerful, turbocharged 2.0L 4-cylinder. Making 252 horsepower and 260 lb-ft of torque, the Envision boasts strong acceleration for its class, even if it's not sports car quick. The only transmission option is a 6-speed automatic, while all-wheel drive comes standard across the entire model range. The Envision is only offered in two trims, Premium and Premium II. While the trim names are somewhat unimaginative, they are never the less accurate, with high levels of features on even the "base" Premium trim. Standard features include leather seating surfaces, heated front and rear seats, a heated steering wheel, 8-way power adjustable front seats, a driver memory system for the seats and mirrors, tri-zone climate control, a Bose sound system, keyless entry, 19" alloy wheels and a park assist system. The Premium II trim adds HID headlights, cooled front seats, automatic high-beams, a heads-up display system projected onto the windshield, an automatic parking assistance system and a navigation system. Options on the Buick Envision include a programmable power liftgate, a power sliding panoramic moonroof and adaptive cruise control. Buick has paid particular attention to the safety features available on the Envision. Beyond the now expected airbags, anti-lock brakes, traction control and stability control, the Envision features some sophisticated safety systems, most of which come standard on either trim level. Standard safety features include a lane keep assist feature, a blind spot warning system, a rear cross traffic alert system, a rearview camera and what Buick is calling a "Safety Alert Seat" which will pulse to alert the driver of a possible crash. The Buick Envision is also available with a surround vision system which uses various cameras mounted around the vehicle to give the driver an unobstructed view of their surroundings.
