Opel and Buick traded places for the latest round of sport sedans. The 2018 Buick Regal GS will roll out with a naturally-aspirated 3.6-liter V6 engine, while the old Buick Regal GS’ 2.0-liter four-cylinder turbocharged engine will power Opel’s Insignia GSi. The lovely 2.8-liter turbocharged V6, found in the old Insignia OPC, is finally laid to rest.
Despite Opel ditching the blown V6, the new Insignia GSi is no slouch. Opel says the new Insignia GSi lapped the Nürburgring 12 seconds quicker than the old Insignia OPC. Opel Director of Performance Cars and Motor Sport, Volker Strycek, says the Insignia GSi is easier to control, which helped make the car faster around the demanding circuit.
It helps Opel shaved just over 350 pounds from the Insignia GSi over the OPC and a set of sticky Michelin Pilot Sport 4 S tires are at each corner. “The lightweight architecture, the excellent chassis configuration with uprated damper hydraulics and software adjustment, the unique all-wheel drive along with the performance tires make the GSi as precise and sharp as we wanted it to be,” said Strycek.
If Opel’s first tests are anything to go by, we’re looking forward to getting our hands on the 2018 Regal GS.
