GME said that, unlike its many competitors, the new Insignia variant is not a low-end model, but “a car that combines powerful propulsion and driving fun with ultimate efficiency”.
The standard model already has a drag coefficient of only 0.27 but the ecoFLEX model has modifications to reduce road and wind resistance giving a cleaner .26 coefficient and a quieter cabin, said to be the quietest Opel ever. The new model has fuel-efficient Michelin Primacy HP tyres developed specifically for the car.
A two-litre, 160hp, single turbo diesel with innovative ‘clean tech process’ to maintain the lowest possible emissions over its life span is fitted. The zero to 100km/h (62mph) acceleration time is 9.5sec and top speed is 218km/h.
Maximum torque of 350Nm is available from 1,750 rpm, and can be increased for 15sec to 380Nm via an ‘overboost’ function.
