Buick Announces 2018 Regal Wagon at Annual Dealer Meeting? by Michael Accardi May 30, 2016May 30, 2016 Share Comments Thread Buick has confirmed to dealers there will be a 2018 Buick Regal Wagon available in the US. The news comes from one of our own who attended the annual Buick-GMC dealer meeting last week in Austin, Texas– in addition dealers were shown the 2018 Enclave, 2018 Regal and Regal GS. The model is expected in North America as a rebadged Opel Insignia Sports Tourer. No powertrain info was offered, but don’t expect it to stray too far from the regular Regal. If GM’s trademark applications are anything to go off, it could wear the Buick Regal TourX name, indicating AWD is likely.
