Two things leak more than the bathroom faucet at your Great Aunt Martha’s cottage in Saugatuck.

The White House.

And Buick.

It seemed fairly clear three months ago that something was afoot when GM Canada’s Buick.ca website momentarily revealed the 2018 Buick Regal GS’s powertrain: a 3.6-liter V6 and all-wheel drive. But Buick declined to comment, removing from the Canadian website the section that mentioned a V6 offering.

Once again, however, Buick appears to have let the horses out of the barn. Buick’s in-house magazine, B, revealed details ahead of schedule, GM Authority has learned. Rather than the 259-horsepower 2.0-liter turbocharged four-cylinder of current GSs that too often feels underwhelmed, B magazine says the 2018 Regal GS, “employs a high-feature V6 engine that furnishes an estimated 310 horsepower.”

The V6 liveth.

With every automaker going all-in on cavernous crossovers and SUVs, Buick certainly hasn’t ignored the trend. The traditional, big-car brand even went so far as to bring us a crossover from China. Still, there’s a legacy nameplate in the lineup in need of nurturing, and it seems only natural (and prudent) that the next-generation Regal ratchets up the versatility.

For 2018, the Regal splits into two body styles, with the traditional variant offering more cargo room than before. Thanks to the midsize model’s Opel Insignia architecture, we’re here to announce a funeral for a longtime member of the automotive world — the Regal’s trunk lid. Yes, this sedan sports a liftback.

If it doesn’t seem like this newly enlarged cargo space will swallow your family’s lifestyle debris, Buick would also like to offer you an all-wheel-drive wagon.
