The Buick Regal takes a lot of inspiration from the Opel Insignia, GM's mainstream large family sedan in Europe. In fact, the Regal is such a close cousin that early models were built alongside the Insignia at the German plant. Sized similarly to rivals like the Acura TLX, Audi A4, Volkswagen CC and Volvo S60, the Regal holds four adults in comfort (or five in a pinch) and makes a case as a sportier and more premium rival to the mainstream family sedan.
Introduced for 2011, the Regal launched with a 2.4-liter four-cylinder engine and 182 horsepower mated to a six-speed automatic, available only in CXL trim. A turbocharged four-cylinder engine with 220 horsepower was made available later in the year with the launch of the CXL Turbo trim.
For 2012, a new performance GS model was added to the lineup. The GS featured a turbocharged 2.0-liter four-cylinder engine with 270 horsepower, a standard six-speed manual or optional six-speed automatic, as well as a special front fascia design, 19-inch wheels, a firmer suspension and bigger brakes. An eAssist model also launched in 2012, which features a 2.4-liter four-cylinder engine and a mild hybrid system for improved fuel economy. Buick's IntelliLink infotainment system replaced the old audio system. All Regals were produced in Canada from here on.
There were few changes for 2013, other than the base 2.4-liter engine being dropped and replaced by the eAssist powertrain as the base setup.
The Regal benefitted from a mild revision in 2014 that brought subtle changes to the exterior, but numerous ones inside and under the skin. Most models were now powered by a new 259 horsepower 2.0-liter turbo, which is brawnier than the previous turbo motor but less powerful than the version in the old Regal GS. The new engine could be had with all-wheel drive, which was a new option for the 2014 model year. Regal GS models continued with the no-cost option of a six-speed manual on front-wheel drive models. A new interior brought a simplified dash to go with a new 8-inch color touch screen, while the GS added an adaptive TFT display in the instrument panel. The eAssist version continued to be offered on non-GS front-wheel drive models.
For 2015, the Regal got a 4G LTE hotspot and Siri Eyes Free through the IntelliLink system.
