VAUXHALL has launched a new petrol engine in the Vectra and Signum ranges, offering lower company car tax bills and more power.

The new 1.8-litre VVT (for Variable Valve Timing) unit offers 137bhp – 15% up on the 1.8-litre engine it replaces, yet CO2 emissions have fallen a benefit-in-kind tax band from 175g/km to 173.

In the case of the SRi version, emissions have fallen from 182g/km to 173. For the SRi, this means a £311 saving in company car tax over three years for a 22% taxpayer.
