The profile photos also show a roof spoiler and a new set of wheels. Like the sedan, the Insignia OPC Sports Tourer will ride on 19-inch alloys shod in 245/40 high performance tires while 20-inch lightweight forged wheels with 255/35 tires will be available as an option.
As you probably have already guessed by now, under the skin you'll find the same hardware used in the Insignia OPC sedan. In other words, a four-wheel drive chassis mated to a 2.8-liter V6 fitted with a twin-scroll turbo that generates an output of 325 horsepower and 400Nm or 295-lbs/ft of torque. Power is channeled to all wheels through a six speed manual gearbox. As with the sedan, the transmission is coupled to an electronic limited-slip differential (eLSD) that can feed torque to individual wheels.
Since it's almost certain that the Insignia OPC Sports Tourer will be a bit heavier than its sedan sibling, don't be surprised if you see slightly worst acceleration figures. For the record, the OPC-ized Insignia saloon hits the 100km/h mark in 6.0 seconds (0 to 60mph in 5.8 seconds). Top speed should remain the same at 250km/h or 155mph (electronically limited).
