The Buick Regal returns for its sixth generation with two new, unconventional profiles: a “Sportback” fastback sedan and a TourX station wagon version.

Perhaps Buick’s most recognizable nameplate, the Regal has been a staple of the tri-shield’s stable for more than four decades. More than that, it’s been one of GM’s more successful attempts to attract new buyers to the brand, with the company claiming more than 40% of Regal buyers in the previous generation came from non-GM brands. For this new generation, Buick is trying something different with the Regal, offering fastback sedan and wagon variants, as well as a performance GS version that sees the Regal boasting V6 power for the first time in 13 years.
