Vauxhall has unveiled further details about its facelifted version of its Insignia upper medium model, ahead of it going on sale next month.
According to Vauxhall the revised version is 18% more efficient than the outgoing model, thanks to low-friction gearboxes, an electro-hydraulic brake booster, mechatronic suspension and four-wheel drive with torque vectoring.
The new Vauxhall Insignia engine range features three- and four-cylinder units, beginning with a 1.4-litre (145hp) petrol engine and a 1.5-litre (122hp) diesel. The three-cylinder engines are 50kg lighter than their predecessors in the outgoing model. Above these are two 2.0-litre petrol engines with 200hp and 230hp, as well as a 2.0-litre four-cylinder diesel, which will be introduced later this year, the company said.
The most efficient model in the range is the 1.5-litre diesel unit; it emits 121-130g/km of CO2 depending on the specification and returns between 57.6mpg and 61.4mpg, according to the new WLTP vehicle testing regime.
Vauxhall added the model features a full-face active shutter for the first time to boost efficiency. Located around the front grille, the shutter closes at the top as well as the bottom. Taking thermal, electrical and aerodynamic factors into account, the upper and lower portions of the grille open and close to make the Vauxhall Insignia even more economical to run, the company said, adding that in addition, the full-face shutter can also delay cooldown after switching off the engine or accelerate warm-up after a cold start – particularly useful in winter, offering significant benefits to fuel consumption and cabin heating comfort.
