A 2.0-litre diesel is coming but the emphasis here is very much on the petrol motors. The four-cylinder unit is the first Vauxhall to come with cylinder deactivation. So unless you need maximum power, a lot of driving can be done on just two cylinders, further enhancing the new model’s economy credentials.
All the new engines are mated to low-friction gearboxes – six-speed manual and eight and nine-speed autos are available, depending on the engine. All models also get active front grille shutters that open and close automatically depending on temperature, allowing the car to warm up more quickly.
The result across the new Insignia range is CO2 emissions that start as low as 100g/km in the entry diesel manual, which also records 61mpg in the new WLTP fuel consumption test. The GSi model gets 34mpg.
The latest Insignias already look crisp and smart thanks to a recent styling update centred around the availability of IntelliLux LED headlights, with a camera-connected control unit constantly adjusting the 84 LED bulbs in each headlight to every traffic and weather situation.
