After scores of spy shots, the facelifted Opel Insignia OPC, otherwise known as the Vauxhall Insignia VXR in Britain, has been officially revealed in advance of its world premiere at the International Automobile Exhibition (IAA) in Frankfurt next month.

To get the first piece of information that everyone is interested in out of the way, there are no changes to the Insignia OPC’s powertrain. The latter links a 320hp (325PS) and 435Nm (321 lb-ft) turbocharged 2.8-liter V6 to a standard six-speed manual (auto is optional) and all-wheel drive for a 0-100km/h (62mph) sprint in 6.0 seconds (Sports Tourer in 6.3 seconds) and a top speed of 250km/h (155mph) in standard form and 270km/h (168mph) in unrestricted specification (Sports Tourer 265 km/h).

What is different about the 2014MY Insignia OPC in terms of performance is the chassis and especially the re-worked rear axle where Opel engineers have modified around 60 percent of the componentry. Furthermore, there’s a re-programmed ESP, and modified damper software for the FlexRide chassis with its adjustable shock absorbers. The German company says these changes will make the high-performance Insignia “more fun to drive”.

On the outside, the OPC sports the new headlamp and taillight designs of the rest of the series along with a revised front grille and tailgate trim, while inside, Opel gifted the top Insignia with a brand new instrument panel, center console, gearshift knob and steering wheel controls.
