A twin-sequential turbocharger is what sets this diesel-powered Insignia apart from normal models, gives it 195 PS and 57.6 mpg.

Vauxhall Insignia BiTurbo is based on the existing 1956cc unit which powers key models in the Insignia, Astra and new Zafira Tourer range. But thanks to the clever turbo system, it makes 35PS more power and a significant 50Nm of extra torque, up to 400 Nm.

So it does 0 to 60mph in 8.2 seconds (Insignia FWD Hatch), while averaging 57.6mpg, 2.2mpg better than the single-turbo 2.0 CDTi 160PS model and emitting no more than 129g/km.

Equipped with Torque Transfer Device (TTD) and the rear axle’s electronically controlled Limited Slip Differential (e-LSD), the car is available with either front or all-wheel-drive system and can even be specified with high-end technologies such as Front Camera System, with traffic sign recognition and lane departure warning, and Adaptive Cruise Control.

The Insignia BiTurbo is available with a choice of five-door Hatch and Sports Tourer bodies in SRi, SRi Vx-line and Elite trims, priced from £27,120 on the road.

Now, if you want to know how this system works, buckle up for some boring technical details:

What makes the Insignia BiTurbo unique in this class is its use of sequential turbocharging, with the smaller turbo accelerating quickly at lower engine speeds to eliminate ‘lag’, providing 350Nm of torque from just 1500rpm. In the mid-range, both turbochargers work together, with a bypass valve allowing gases to flow from the small to large unit; during this phase, maximum torque of 400Nm is produced between 1750-2500rpm. From 3000rpm, all gases flow directly to the larger turbo, ensuring performance is maintained at higher engine speeds.
