Buick just took the wraps off the 2018 Regal last week, but rumors are already flying. The only official powertrain option announced for the new Regal Sportback and TourX is GM’s 2.0-liter turbocharged inline-four, but TTAC noticed on Buick’s Canadian website that a V-6 may be coming.
According to the report and the subsequent screenshot of Buick’s site, a Regal GS is referenced featuring a 3.6-liter V-6 engine. Given the fact that GM’s well-known 3.6-liter V-6 ranges in horsepower from 315 to 335, it is a very realistic option for a GS performance model.
This would mark the first time Buick has put a V-6 in the Regal since it returned to the market back in 2010. For those old enough to remember, prior to the launch of the Regal in 2010, rumors surfaced that a GS model was going to be powered by the 3.6-liter V-6 as well. It turned out that the Regal GS yielded only a higher output version of the car’s 2.0-liter turbo, to the disappointment of many enthusiasts.
There’s no word yet on if or when a Regal GS could launch, much less a confirmation of its powertrain. Thus far Buick has not officially commented on the leak and probably won’t until there’s GS news to share.
