OPC cars typically feature minor engine and handling mods as well as styling and performance upgrades such as bigger wheels and sporty bodykits. In the UK, the car will likely be known as the Vauxhall Insignia Sports Tourer VXR.
The oversized wheels and cross-drilled brake discs of this latest prototype suggest that this is a new performance variant of the standard Insignia. The latest images also reveal the car will feature a Brembo developed brake package. A V6 badge at the rear of the car, meanwhile, confirms that the 260hp (194kW) 2.8L engine from the standard model will also be used in the OPC, however, the addition of a turbocharger system could boost power levels beyond 300hp (225kW).
Previous reports suggest that a new AWD system will be fitted to the car to improve handling, while stiffer suspension and an uprated steering system will also improve track performance. The expected AWD system is the same torque-splitting electronic differential used by Saab for its 9-3 Turbo X.
With rumors the Insignia could be heading Stateside as the 2010 Buick Regal, there’s now a chance that this high-performance OPC Sports Tourer, as well as its sedan sibling, could be offered in the U.S. as well.
