Buick Regal (modern)

The modern Buick Regal (2011-2020) was a complete reset of the model name — based on the Opel Insignia, federalised for the US market, and aimed at rejuvenating Buick's appeal to younger buyers. Two distinct generations: first gen (2011-2017) on the Epsilon II platform, four-door sedan only, with multiple engines including a 2.0L turbo I4 (220-270 hp on GS), 3.6L V6 (270 hp), and a 2.4L hybrid eAssist mild-hybrid system. Second gen (2018-2020) on E2XX platform with two body styles: five-door fastback Regal Sportback (replaced the conventional sedan) and Regal TourX five-door station wagon — the first Buick wagon since the 1996 Roadmaster Estate. Engines on second-gen: 2.0L turbo I4 (250-310 hp on GS V6), 3.6L V6 (310 hp on GS). Manual six-speed offered briefly on 2014-2017 GS — rare among 2010s American luxury sedans. Discontinued 2020 in North America when GM exited the Insignia partnership with the broader Opel sale. Now firmly affordable used; manual GS sedans and TourX wagons are the cult specs.
