The Buick Regal is a mid-size sedan produced by American automaker Buick from 2011 to 2017, marking a significant departure from its previous iteration. The 2011-2013 models, the focus of the Factory Workshop Service Repair Manual, marked the first generation of the redesigned Regal and introduced a more European-inspired aesthetic with sleek lines, a spacious interior, and a sporty driving experience. Built on the Epsilon II platform shared with its Opel Insignia counterpart, the Regal offered a range of powertrain options, including a 2.4L four-cylinder engine, a 2.0L turbocharged four-cylinder, and a 3.6L V6 engine, all paired with six-speed automatic transmissions. Notable features included a standard six-speaker sound system, Bluetooth connectivity, and a touchscreen infotainment system. Higher trims like the Turbo and GS added features like leather upholstery, heated and ventilated seats, a sunroof, and a sport-tuned suspension.
