VIDEO: Opel Insignia OPC Unleashes its 300HP+ on the Nurburgring

While not as powerful as the BMW M3 Sedan, the new Opel Insignia OPC with its bi-turbocharged 2.8-liter V6 engine that is slated to develop anywhere between 300 and 320HP could give Audi's S4 sports sedan a good run for its money. The high-performance version of the Insignia which is due to be officially revealed this month, also comes with GM's latest all-wheel drive system featuring an electronically-controlled, rear limited slip differential.

In this new spy video -courtesy of Car Magazine- the Insignia OPC was caught in action on the Nurburgring race track. Once you have finished watching the video, click here for more details and high-res photos of the Insignia OPC.
