General Motors has woven an intricate vehicle in the 2018 Buick Regal. Not only will it be sold here in North America, but also in Europe as the 2018 Opel Insignia Grand Sport and in Australia as the 2018 Holden NG Commodore. That means information coming out of Europe and Australia is just as valuable as reports originating here.
In this case, it involves the 2018 Opel Insignia OPC, which will likely feature very similar appointments to our next 2018 Buick Regal GS. Car Advice reports Opel will kill off the 2.8-liter turbocharged V6 engine (which dates back to Saab days) and replace it with a turbocharged four-cylinder unit instead.
“The VXR will only be for Australia [referring to the use of the 3.6-liter LGX V6]. We call it an OPC and we will not have a V6 in this one,” General Motors Europe technical integration engineer Andreas Liljekvist said. “Yes, it will be all-wheel drive and probably a four-cylinder.”
The statement dashes hopes of the 3.6-liter twin-turbo LF3 V6 engine finding its way to the 2018 Buick Regal GS, as Buick hinted previously. The twin-turbo V6 produces 410 hp and 369 lb-ft of torque in the Regal’s closest sibling, the Cadillac XTS V-Sport.
It also provides little clarity to what Buick has planned for powertrains in North America. The current Regal is sold with either the 2.4-liter naturally aspirated four-cylinder or 2.0-liter LTG turbocharged four-cylinder. The current GS receives the same turbo-four as other Regal models.
Therefore, we’re left in the dark as to if the 2018 Regal GS will feature the same 2.0-liter LTG turbo four once again, or if reports of the LGX V6 coming are in fact for the performance-oriented Regal GS.
