Buick Regal GS
Buick’s new 2014 Regal is a sportier and smarter evolution of the brand’s dynamic midsize sedan. New, purposeful technologies enhance safety and the driving experience with a more refined turbo engine – along with the introduction of all-wheel drive.
The new Regal also introduces new radar- and camera-based safety features – including Rear Cross Traffic Alert, Lane Change Alert, Side Blind Zone Alert, Lane Departure Warning, Forward Collision Alert and Collision Mitigation Braking – for surround protection. In-vehicle connectivity is enhanced with next-generation IntelliLink, featuring simpler, more intuitive controls and natural speech recognition.
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.
“The new 2014 Regal is more expressive, more connected and more technologically advanced,” said Tony DiSalle, U.S. vice president of Buick Marketing. “ The new Regal gives those discerning buyers more of the technologically advanced features they want in a modern luxury sedan, all with the style and refinement they expect from Buick.”
New front and rear styling, with available wing-shape LED daytime running lamps and standard LED taillamps, were designed to give Regal a more contemporary and premium presence. The interior features a redesigned central instrument panel and console.
The new 2.0L turbo four-cylinder engine is standard on Regal and delivers 18 percent more horsepower than the 2013 Regal Turbo for a greater feeling of on-demand power. It also contributes to greater efficiency, with city mileage for Regal increasing 17 percent to an EPA-estimated 21 mpg (FWD and automatic transmission). Estimated highway mileage for FWD automatic models also increases to 30 mpg. With Regal GS automatic models, the EPA mileage estimates increase more than 10 percent in the city, to 21 mpg, and about 11 percent on the highway, to 30 mpg (FWD models). With Regal GS and the six-speed manual, the highway mileage estimate increases 15 percent, to 31 mpg.
Regal’s available Haldex all-wheel-drive system helps make the most of traction in all driving conditions and also enhances the cornering capability of the Regal GS when driven in the GS mode of the Interactive Drive Control System. A new H-arm rear suspension design is standard on all Regal AWD models. FWD models employ a four-link rear suspension.
A 2.4L engine with eAssist light electrification technology is also available on the 2014 Regal (FWD only), delivering EPA-estimated ratings of 25 city and 36 highway. Six-speed automatic transmissions are matched with both engines and a six-speed manual is available exclusively in the Regal GS. Electric power steering is now featured on all models.
Regal is available in four trim levels, including GS. They are: Regal (1SL), Premium I (1SN), Premium II (1SP) and GS (1SX). Buick IntelliLink is standard on all Regal audio systems, and uses Bluetooth wireless connectivity or USB to connect the driver’s smart phone to an eight-inch, high-resolution, full-color touch screen display radio.
The Regal GS is designed to deliver a dynamic driving experience through sophisticated suspension technologies, premium amenities and a more expressive presence.Along with its standard turbocharged powertrain, the GS features the exclusive application of Buick’s Interactive Drive Control system, which allows the driver to select different drive modes – including the GS mode and its track-oriented competitive setting.
In GS mode, the Regal increases steering efforts for more direct feedback to the driver. Increased damping levels ensure ultimate wheel control and reduced body roll for better agility. GS mode also is designed to alter the shift feel of the six-speed automatic transmission.
The GS’s HiPer Strut front suspension – standard on FWD and AWD models – enhances ride and handling by reducing torque steer; more linear and communicative steering through improved camber control; and improved impact isolation on bumps and rough surfaces. It is complemented by a four-wheel-disc brake system featuring front Brembo four-piston front calipers and larger rotors.
A four-link independent rear suspension on FWD models is designed to minimize unwanted toe and camber effects during spirited driving maneuvers, enhancing vehicle stability. Both front and rear dampers incorporate active Computer Damping Control, continuously changing damper characteristics that optimize ride comfort and handling capabilities over varying road surfaces and profiles. More aggressive, performance-oriented damping characteristics can also be selected by the driver through the Interactive Driver Control system.
Regal GS with AWD features a new H-arm rear suspension that uses the same attachment points as the four-link system, but with the cross member attached via isolated mounts. This system delivers excellent ride quality and handling, while minimizing road noise.
Additionally, the Regal GS features a lowered ride height and 19-inch aluminum wheels to project a sporty, purposeful stance. Twenty-inch wheels with summer-rated performance tires are available.
Unique front and rear fascias distinguish the GS. The front fascia incorporates prominent, vertical air intake slots. The rear fascia features a pair of integrated, satin-metallic trapezoidal exhaust outlets. Rocker panel extensions and a rear spoiler extension are also part of the package.
A new 2.0L turbo four-cylinder engine debuts as the standard powertrain in the 2014 Regal and Regal GS, advancing the legacy of an engine recognized as one of Ward’s 10 Best Engines in 2012. Although it shares the same displacement as the previous turbo engines offered in the Regal, it is a next-generation architecture with friction-reduction technologies designed to enhance refinements on a variety of levels.
Along with its SAE-certified 259 horsepower (193 kW), the new 2.0L turbo’s torque curve has been enhanced, delivering 90 percent (260 lb-ft / 353 Nm) of its peak torque from 1,700 rpm to 5,500 rpm and the full 295 lb-ft of peak torque (400 Nm) from 3,000 to 4,000 rpm in the Regal. For the Regal GS, peak torque is reached at 2,500 rpm and is maintained through 4,000 rpm. Those broad torque bands are supported by boost levels as high as 24 psi (1.65 bar) in the speed range, engineered to give the Regal and Regal GS assuring, exhilarating feelings of immediate power on demand.
The turbocharger features a twin-scroll design that uses exhaust tuning to generate balance between maximum power and excellent turbo response, enabling the engine to deliver a broad torque band. It also supports the responsiveness associated with larger-displacement, naturally aspirated performance engines. Boost is controlled electronically with a pressure-actuated wastegate and the airflow is controlled during transients with an electronic bypass valve. Those controls enable optimal performance, throttle response and efficiency.
