The Insignia is the latest Vauxhall to receive the new 1.6-litre 'Whisper Diesel' engine.
The new version of the mid-size turbo engine replaces the current 2.0-litre units and was developed. says Vauxhall, to deliver "exemplary responsiveness and low consumption with exceptional running smoothness".
The 1.6 CDTi (136PS) ecoFLEX version achieves a top speed of 130mph and 0-60mph in 10.9 seconds. When specified with 17-inch alloy wheels and ultra-low rolling resistance tyres (Design, SE, Tech Line and SRi models only) it emits 99g/km of CO2 and returns up to 74.3mpg on the combined cycle.
Also new to the Insignia range is the OnStar system which delivers a Wi-Fi hotspot for up to seven devices, emergency response notification if the airbag deploys and stolen vehicle recovery technology. Connecting drivers directly with a call centre advisor, it provides owners with a personal assistant 24/7. For example, with Destination Download, you can call your OnStar advisor in-car and they'll pinpoint your desired destination and send the address to your vehicle's navigation system. OnStar is available as standard on Elite, Limited Edition and VXR trims and as a £395 option on other models.
In addition, the second generation Navi 900 IntelliLink that utilises Apple CarPlay, offers fast access to many entertainment apps for music and news, via the eight-inch colour touchscreen interface.
IntelliLink reads out incoming text messages and enables audio streaming, voice control and the watching of films and videos - when the car is stationary, of course. The navigation system features maps of more than 30 European countries and can be displayed two or three-dimensionally and controlled by voice command.
The Vauxhall Insignia powered by the 1.6 CDTi engine is priced from £19,534 to £26,114 on-the-road.
