What is it?
According to its creators, the Insignia VXR is three things: the 155 mph flagship version of Vauxhall’s thriving Insignia executive car range, the car that finally lifts its 10-year run of VXR-badged performance models above the raucous, boy-racer tag that has always stuck to them, and a performance car from GM Europe that honestly deserves to turn a BMW buyer’s head.
These are big claims — and assessing each one depends on a dispassionate examination of the driving experience, so we drove a car as fast as we could legally go from Frankfurt to London, to discover the worth of them.
What's it like?
Well, it certainly has the on-paper credentials.
The 2.8-litre turbo V6 has hotter camshaft profiles, bigger injection nozzles and more aggressive engine management parameters so it produces 321 bhp at 5250 rpm instead of the standard V6’s 255.
It gets a high performance 4wd system with electronically managed torque splits, adaptive electronic traction controls depending on how you drive, plus lightweight Brembo brakes with four-piston calipers and hybrid alloy discs with cast-iron centres.
You get a specially tuned chassis, 20mm lower than standard, including special, low-friction “hyperstruts” that cut steering friction and improve feel. You get a three-level ride control system (firm, hard, harder), which also adjusts things like steering weight and accelerator “alertness” as it goes.
There’s a magnificent set of specially adapted Recaro seats and just about every interior nicety you can imagine, short of on-board TV and radar cruise control.
The VXR is relatively quiet but sounds lovely when you give it the beans. It is governed at 155 mph (could probably crack 170), can run a 0-60 mph sprint in 5.8 seconds, and accelerates 50-75 mph in 7.1 seconds.
That’s big performance in a cross-Europe grand touring sense, but not quite enough to match true tyre-burners like the BMW M5 or Audi RS6. But few owners will think it too slow.
