Powerful Bi-Turbo engine to give Vauxhall Insignia all-new driving dynamic

By / 10 years ago / Latest News / No Comments

Vauxhall has launched a new high performance edition of its top selling Insignia. Known as the Insignia BiTurbo, it’s available as a five-door Hatch and and Sports Tourer estate, offering a choice of front and four-wheel drive.

Trims on offer include SRi, SRi VX-line and Elite, on the road prices start from £27,120.

The car will be supported by the same initiatives aimed at fleet customers that helped the car to honours in the 2011 Fleet World awards – including a three-day test drive scheme and 100,000 mile lifetime warranty programme.

More power, improved economy
The potent, twin-sequential turbocharged diesel is based on the existing 1956cc unit already available in key models in the Insignia, Astra and new Zafira Tourer range. However, in BiTurbo form the engine produces up to 35PS more power and a significant 50Nm of extra torque, reducing the 0-60mph time by nearly one second, to 8.2 seconds (Insignia FWD Hatch).

But thanks to a package of eco features – including standard Start/Stop across the range – the FWD Hatch achieves a combined 57.6mpg, 2.2mpg better than the single-turbo 2.0 CDTi 160PS model.

Vauxhall's use of stop/start technology is highly acclaimed, and recently helped the the firm's high performance VXR8 to a class win in the 2011 Fleet World MPG Marathon.

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.

Flexride active suspension as standard
Complementing this power gain, Vauxhall’s clever FlexRide adaptive damping is standard on all Insignia BiTurbos (normally a £790 option on front-wheel drive Insignias). The system reacts within milliseconds to driver inputs and can ‘learn’ how the car is being driven and adapt damper settings accordingly. Drivers can also select Tour and Sport buttons, and configure the throttle, steering and damper settings in Sport mode separately.

On four-wheel drive models, FlexRide is integrated with the car’s Torque Transfer Device (TTD) and the rear axle’s electronically controlled Limited Slip Differential (e-LSD). These features allow torque to be automatically transferred between front and rear wheels, and between left and right wheels on the rear axle, offering exceptional levels of traction, grip and control.

Enhanced safety systems
In common with other models in the Insignia range, the BiTurbo has the option of Vauxhall’s new Front Camera System, with traffic sign recognition and lane departure warning, and Adaptive Cruise Control, which allows the driver to maintain a set distance from the car in front.
