Spied: Insignia OPC at the Ring

Now the final iteration has been spotted prowling the Nurburgring during a stint of performance testing.

Whilst on paper, the Insignia may seem out of place of the world's most infamous circuit; this is actually our first glimpse of the performance flagship OPC model.

No doubt hiding some new performance flare behind the duct tape, the OPC variant is expected to boast a new front skirt with bigger air intakes, wider sills and wheel arches, and a moulded rear lip spoiler.

Under the hood is a new turbocharged V6 power plant which should deliver over 220kW, likely mated to a performance version of the lesser model's all-wheel drive system.
