Insignia customers can now opt for the radar-based Adaptive Cruise Control (ACC). The new system maintains the selected speed during cruising, yet automatically adjusts the vehicle speed according to traffic conditions to secure a pre-set safety distance with vehicles ahead.

Further functionalities are available in conjunction with the radar system: The Following Distance Indication (FDI) informs the driver visually about the distance to the car ahead; the Forward Collision Alert (FCA) provides a visual and an audible signal to warn the driver of an imminent collision with the car ahead; and the Collision Imminent Braking (CIB) automatically decelerates the vehicle if the risk of a collision is detected.

The new 2.0-liter BiTurbo power unit delivers 143 kW (195 hp) and 400 N·m (295 lb-ft) of torque; the four-door sedan with front wheel drive and manual transmission consumes 4.9 liters per 100 km (48 mpg US), equivalent to 129 g/km CO₂. All versions with manual transmission are equipped with Start/Stop.

The Insignia front-wheel drive (FWD) sedan with six-gear manual transmission accelerates from 0 to 100 km/h in 8.7 seconds and has a top speed of 230 km/h (143 mph).

In this class of power and torque, six-cylinder diesel engines with around three liter displacements are the usual choice. With our BiTurbo technology smaller engines produce even more output while enabling 30 percent lower fuel consumption and emissions. This is a very good example of successful downsizing by Opel.

The highlight of the four-cylinder common rail engine is the sequential double turbo system with two charging stages. (Earlier post.) Buyers have the option to combine the new engine with front or all-wheel drive (AWD). The Insignia 2.0 BiTurbo CDTI is available in all body styles.

Further, starting in spring 2012, the all-wheel drive (AWD) variants can additionally be ordered with the SuperSport Chassis that comes complete with the front-wheel suspension of the Insignia OPC (Opel Performance Center). This suspension is fitted with high performance struts (HiPerStruts), further enhancing driving dynamics.
