What is it?
This is the flagship of the Insignia range. Power comes from the same turbocharged V6 that does duty in the Saab 9-3, with the Vauxhall getting 257bhp and 258lb ft of torque, rising to 280lb ft on overboost.
The daddy Insignia also gets four-wheel drive as standard, using a Haldex clutch to divert torque rearwards. It also shares the Saab's 'torque vectoring' differential to shunt drive left to right for maximum traction.
A six-speed automatic is standard; Opel buyers get the option of a six-speed manual, but it won't be sold in the UK.
The car also gets GM's 'FlexRide' adaptive damping system, with the 'sport' suspension setting also turning the instrument pack illumination from white to red.
What's it like?
It's a good-looking car, with a wide-track stance distinguishing it from lesser versions of the Insignia. The V6 motor delivers plenty of punch, with a 7.1 second 0-62mph time and a top speed limited to 155mph.
