Opel says its new Insignia breaks the barrier across a number of categories such as fuel efficiency, aerodynamics and connectivity with 'IntelliLink'.
There is a new two-litre diesel with 140hp that replaces the 130hp.
Fuel consumption falls to 3.7l/100km and CO2 emissions drop to a very credible 99g/km.
New Insignia has low Cd values of just below 0.25 and 0.28 for the Insignia hatchback and Sports Tourer respectively.
Opel says this makes Insignia the most aerodynamic car in its class – in the world!
Insignia's IntelliLink features two visual display screens and four modes of operation: eight-inch colour touchscreen; steering wheel-mounted controls; voice recognition and via the revolutionary touchpad, which supports handwriting recognition and haptic feedback.
'S', 'SC', 'SE', 'SRi' and 'Elite' are the specification grades from launch.
