The base 1SV Regal starts with 18-inch alloy wheels, automatic xenon headlights, foglights, remote keyless entry, heated power mirrors, cruise control, dual-zone automatic climate control, leather upholstery, heated front seats, an eight-way power driver seat (with two-way power lumbar), a power, height-adjustable passenger seat (with manual adjustments), split-folding rear seats, a tilt-and-telescoping leather-wrapped steering wheel and an auto-dimming rearview mirror. Also standard are Buick's IntelliLink infotainment system (with an 8-inch touchscreen), a rearview camera, Bluetooth phone and audio connectivity, Siri Eyes Free (giving iPhone users voice control over a range of functions via the Bluetooth microphone), Apple CarPlay and Android Auto for enhanced smartphone functionality, a Wi-Fi hot spot with 4G LTE data, OnStar emergency communications, and a seven-speaker audio system with a CD player, satellite radio and two USB ports.
The Sport Touring trim adds a more powerful turbocharged engine and dual exhaust outlets as well as unique 18-inch wheels with black-painted pockets and a rear spoiler.
The Premium II adds front LED signature lighting, rear parking sensors, rear-seat side airbags, keyless entry and push-button ignition, remote start, a heated steering wheel, an eight-way power passenger seat (with two-way power lumbar), a 110-volt power outlet, a navigation system and a nine-speaker Bose audio system.
The range topping Regal GS comes with 19-inch wheels (20-inch wheels with summer tires are optional), unique front and rear fascias, front and rear parking sensors, a sport-tuned suspension with adaptive dampers, two selectable drive modes (influencing suspension, steering and shift calibration), Brembo front brakes, body-color sport rocker panels, an enlarged and configurable gauge-cluster information display, unique pedals, sport front seats and a three-spoke sport steering wheel.
Most of these GS features are exclusive, but the sport-tuned suspension (minus the adaptive dampers) is also specified on non-GS Regals with AWD. Optional on the Premium II and GS are two Driver Confidence packages. The first adds numerous safety technologies (including a blind-spot monitor, lane departure warning, rear cross-traffic alert and forward collision alert) as well as driver memory settings, while the second — which requires the first — adds adaptive cruise control and a forward collision mitigation system with automatic emergency braking.
Stand-alone options, depending on trim, include some of the higher trims' standard features plus a sunroof and 18-inch chrome-clad wheels.
The base 2017 Buick Regal 1SV employs a 2.4-liter four-cylinder engine that generates 182 horsepower and 172 lb-ft of torque to the front wheels through a six-speed automatic transmission. EPA fuel economy ratings, 23 mpg combined (19 city/30 highway), are disappointingly low given the modest output and comparison to the competition.
In Edmunds testing of a Regal with the 2.4-liter powertrain, we recorded a substandard 0-60-mph time of 9.8 seconds. That's by far the slowest time we've recorded for a midsize sedan, let alone a sedan like the Regal with premium pretensions.
The remaining Regal trims rely on a turbocharged 2.0-liter four-cylinder engine rated at 259 hp and 295 lb-ft of torque. Front-wheel drive is standard, with all-wheel drive optional. A six-speed automatic transmission is also standard across the board.
The EPA rates the turbocharged Regal at 24 mpg combined (21 city/29 highway) with front-wheel drive and the automatic, and 22 mpg combined (19 city/27 highway) with AWD.
In Edmunds testing, an all-wheel-drive Regal with the 2.0-liter turbo accelerated from zero to 60 mph in 7.2 seconds, which is slower than many choices in this price range. It's also one of the slowest among midsize sedans with an upgraded engine.
