BT has ordered 242 additional vehicles from Vauxhall following its order of 692 vehicles the manufacturer supplied to the communications company in 2013.

The deal largely consists of the new Insignia in Design trim, powered by the 2.0CDTi 138bhp.

Alongside the Insignias, the rest of the fleet will be made up of a mixture of Corsas powered by the 1.3CDTi 93bhp ecoFLEX engine, the Astra hatch and the British-built Astra Sports Tourer.

The Astra variants will be powered by either the 1.3CDTi 93bhp engine with fuel consumption of 68.9mpg, or the 1.7CDTi 108bhp engine with a fuel consumption of 62.8mpg.
