Differing little from the GSI on first glance with the Holden lion and Buick tri-shield logos mainly replacing the Opel blitz, the biggest changes are reserved for underneath the bonnet where both drop the turbocharged four-cylinder engine for a normally aspirated V6.
Displacing 3.6-litres as opposed to the GSI's 2.0-litres, the unit in the Regal and Commodore produce 235 kW and 381 Nm of torque, up a massive 44 kW but down 19 Nm, mated to a brand new nine-speed automatic gearbox and a Twinster all-wheel drive system similar to that of the Ford Focus RS.
Like the GSI, the Commodore VXR receives 20-inch alloy wheels, Brembo brake calipers, three mode (Standard, Tour, Sport) FlexRide adaptive damping, Torque Vectoring, Matrix IntelliLux LED headlights and on the side inside, branded door sills, heated and ventilated sport seats, flat bottom steering wheel and a faux diffuser. On the Regal GS, 19-inch alloys are standard with the aforementioned LEDs and 20-inch rims optional.
While neither the Regal or Commodore are expected to arrive on local dealership floors, the availability of the GSI, including the standard Insignia Grand Sport, are open to speculation following Opel's announcement last month that it had signed an agreement with Williams Hunt to import vehicles from next year after its sale to the PSA Group. At present though, the Grand Sport and GSI are a no-no.
