What is the Buick Regal?

The Regal is a Buick nameplate that took several forms over the years, from coupes and sedans to the later Sportback liftback and TourX wagon. Those last body styles gave the car a more flexible rear opening and load space than a conventional sedan.

Buick is part of General Motors. The final Regal generation was based on the Opel Insignia and sat in Buick’s mid-size range, with both comfort-focused and sportier versions. It was listed in the United States and Canada through 2020.

Regal generations

The generations represented in North American history are the second (1984–1987), third (1988–1996), fourth (1997–2004), fifth (2010–2017) and sixth (2018–2020). After a gap, the fifth generation brought the Regal back on the Epsilon II platform. The sixth generation used the E2XX platform and moved beyond the traditional sedan shape: the Sportback had a rear hatch, while the TourX was a wagon.

Engines and fuel consumption

The engine range varied by year and market. US EPA listings span 2.0 L to 5.7 L and include petrol, hybrid, flex-fuel E85 and diesel versions. The best combined EPA rating is 29 MPG; the lowest listed consumption is 8.1 L/100 km. Canada’s NRCan listings span 2.0 L to 3.8 L and include petrol and E85 versions, with a lowest figure of 8.2 L/100 km on the 5-cycle test.

In official EU registration figures, one 2019 petrol version appears: a 2.0 L engine producing 187 kW (254 PS), with 20 registrations. European WLTP and older NEDC results, US EPA ratings and Canada’s 5-cycle results use different test procedures, so figures across markets are not directly equivalent.
