Confirmed today, the three cars will enter at the flagship end of their respective model lines, marking the Australian debut of the OPC brand.
“Since we confirmed the Astra OPC at the Sydney show, dealers have reported back strong customer enquiry with many customer orders being placed already," Opel Australia boss Bill Mott said.
OPC has always been on the top of our local wish list and we’re very excited to confirm that when the Astra OPC arrives in March, it will be joined by the Corsa OPC and Insignia OPC."
The Insignia OPC made its global debut in 2009, taking out Auto Bild magazine's Sports Car of the Year award.
Power in the Insignia OPC is drawn from a 2.8 litre turbocharged petrol V6, producing 239kW and 435Nm.
In Australia, the engine will skip the overseas manual option, getting instead the the six-speed auto. An adaptive all-wheel-drive system is also featured.
Opel lists a 0-100km/h time of 6.0 seconds flat for the midsized performance sedan.
As with the Astra OPC, the flagship Insignia gets Opel's HiPerStrut suspension system, along with revised bushing and damper settings at both end.
Big 19-inch wheels are standard, and 20-inch rims will also be available in Australia as an option. Brembo calipers and cross-drilled brake discs sit behind.
A new front bumper with vertical intakes either side of the center air dam beefs up the front end, while the rear bumper includes two large chrome exhaust tips. A boot lid spoiler and new side skirts finish off the look quite nicely.
Interior revisions include Recaro front seats, redesigned instrument cluster and a new three-spoke leather steering wheel.
The oldest of the trio, the Corsa OPC first debuted in 2007 - but there's enough here to make it a true player in its segment even now.
The top-shelf Corsa OPC packs a 1.6 litre turbo engine, delivering a Polo GTI-beating and Clio RS-rivalling 141kW.
Torque betters both, listed at 260Nm with the 'overboost' function in play (230Nm in regular operation).
Sharpening the whole package is a lowered and OPC-enhanced chassis with McPherson struts up front and a torsion beam arrangement at the rear.
Big 17-inch alloy wheels are standard, and braking is managed by a Brembo setup at the front end.
Exterior tweaks include the requisite styling and aero upgrades and a central-mount chrome exhaust tip.
The most recent addition to the current performance line-up is the latest Astra OPC, revealed in November last year.
Sitting above the already-available 132kW GTC three-door, the Astra OPC gets a 2.0 litre turbo four delivering 206kW and 400Nm.
As with the production GTC, Astra OPC uses Opel’s HiPerStrut front suspension design, but adds FlexRide multi-mode dampers, a mechanical LSD and Brembo brakes to help deal with the 2.0 litre’s performance.
Watch for all three models to hit Australia in March, 2013.
