Vauxhall has confirmed prices for its Insignia Grand Sport will start at just over £17k OTR. Based on a completely new vehicle architecture, the 2017 model is 175kg lighter than the previous generation and features new technology such as the Head-up-Display and IntelliLux LED matrix headlights. A choice of six petrol and diesel engines are available with an all-new 1.5-litre petrol unit pumping out 250PS, while the 1.6-litre diesel returns up to 70.6mpg. Order books for the all-new Insignia Grand Sport are open now, with first deliveries beginning in May.
