About 2016 Buick Regal Buick Regal offers a distinctive approach to spirited performance, while delivering the brand's signature quietness and the latest technologies -- including enhancements to Buick IntelliLink for 2016 and the return of OnStar 4G LTE connectivity with a Wi-Fi hotspot. Regal is offered with three powertrain combinations: a 2.4L four-cylinder rated at 182 horsepower, a standard 2.0L turbo four-cylinder engine rated at 259 horsepower, and the optional 2.4L engine paired with eAssist light electrification technology. The Regal's chassis and structural systems were developed globally, enabling the handling and dynamics of a luxury import sport sedan with the quiet, refined ride expected of a Buick. Regal wears the appearance of a contemporary Buick, with cues that reinforce its low, wide proportion and convey an upscale ambience through technology. The prominent, sweptback headlamps are available in two versions, including halogen projector beams and Xenon high-intensity discharge. The 2016 Regal's interior blends sculptural beauty and refinement with technology, centered on Buick's next-generation IntelliLink infotainment system. The instrument panel "center stack" houses the system's eight-inch color touch screen. It is designed for easy operation with intuitive controls and smartphone-influenced swipe recognition for easier navigation. Radar- and camera-based active safety features, including Lane Change Alert, Lane Departure Warning, Forward Collision Alert and Collision Mitigation Braking, and Rear Cross Traffic Alert and Side Blind Zone Alert, are available. Adaptive cruise control is also offered. It senses traffic in front of the Regal to adjust vehicle speed, including stopping the vehicle in heavy traffic and accelerating again.
