GM is negotiating with PSA Group to sale Opel, Buick will stay out of 4 models four models that were taken from Opel: the Encore small crossover, Cascada convertible, Regal midsize sedan and Verano compact sedan, which ended production in October for the U.S.

The deal from 2009 delivered benefit to the GM more than it was ever expected, since american auto maker bough the German company. At that time decision to take over the company to get it out of the bankruptcy and to complement the Buick’s poor product lineup, from only 3 models: LaCrosse, Lucerne sedanas and Enclave crossover.

Buick spokesman Stuart Fowle said it was too early to comment on the potential impact of an Opel sale. ’’Right now, we’re moving forward as Buick, and we’ll cross that bridge if or when we come to it,” Fowl said.

Buick will not suffer is it stays without Opel’s models – brand’s focus has shifted to China

Dave Sullivan, an analyst with AutoPacific Inc., doesn’t believe Buick would be impacted heavily if the sale goes through, as the brand’s focus has shifted to China.

“I don’t think we’re going to feel it here in the U.S. in terms of product life cycles because I think China has taken the lead on Buick development,” Sullivan said.

The most successful Opel-Buick for the U.S. has been the five-passenger Encore, sold in Europe as the Mokka. The South Korea-built subcompact crossover blew past company and analyst expectations, with GM having trouble keeping up with demand.

The Enclave is expected to be on the same platform as the 2018 Chevrolet Traverse, which is a long-wheelbase variant of the platform for the 2017 Cadillac XT5 and 2017 GMC Acadia.

The next-generation Regal could be impacted by an Opel sale. GM recently released photos and some details of the Opel/Vauxhall Insignia Grand Sport, on which the Regal is based. The Insignia, up to 385 pounds lighter than the current version, suggests that the Regal will become slightly wider and lower, with a longer wheelbase.
