For 2014, the Regal gets freshened front and rear styling, updated interiors, enhanced connectivity and infotainment, new safety features, a new version of the standard 2.0-liter turbocharged engines, a new electric power steering system, and the addition of an all-wheel-drive option.
For 2013, the Regal line packaging is simplified slightly, with the 2.4-liter eAssist mild hybrid 4-cylinder becoming the base engine. Buick's IntelliLink smart-phone integration system is now standard on all Regals. A few new paint colors join the palette, though color choices on the GS remain limited.
Two new variants join the 2012 Buick Regal sedan lineup. First is the Regal eAssist hybrid that uses a small electric motor attached to a lithium-ion battery pack to assist the 2.4-liter gasoline engine. The second addition is the stellar opposite of the hybrid, taking the form of a 270-horsepower sport sedan dubbed the Buick Regal GS (Grand Sport). Other changes of note include E85 capability on the 2.4-liter engine and the addition of Buick's IntelliLink Bluetooth-enabled infotainment system (late availability) to all Regal models.
The 2015 Buick Regal comes standard with an upgraded version of OnStar that includes 4G LTE connectivity, plus the ability to turn the Regal into a Wi-Fi hotspot for a monthly fee. In addition, there's now Siri Eyes Free technology for better integration with the voice-recognition technology on Apple's iPhone. The tech upgrades make a difference, giving the Buick a more competitive footing against competitors like the Audi A4, Volkswagen CC, and the all-new Acura TLX. Tracing its roots to Europe's Opel brand, the Buick Regal offers a distinctly Old World driving character that permeates the whole lineup, whether you choose the eAssist mild hybrid model, the mid-level model with the more-powerful 2.0-liter turbocharged engine and all-wheel drive, or the sporty Regal GS.
