Speaking to news agency Headlineauto, he said: ‘Insignia is our flagship car and is by some distance the leader in its class and we expect to perpetuate this with new the model which sees some significant changes inside and out. More important there is a significant price decrease, between £3,000 and £5,000 on some models and we also have a new engine which emits just 99 g/km of CO2. When you look at the benefit in kind bands based on cost and CO2 then we will have an industry-leading proposition for company car users.

‘As well as new and refreshed models coming through we are making a big push on engine technologies which will bring down emissions even further.’
