True fleet sales of Vauxhall’s Insignia were up by more than 50% in the second half of 2013 over the first half of 2013.
Vauxhall launched its new Insignia in June, with a sector leading revised 2.0 CDTi diesel offering CO2 emissions from 98g/km.
True fleet sales are to company car drivers at end user companies and exclude other fleet segments such as rental and Motability.
"It is fantastic to see this growth," said James Taylor, Vauxhall’s fleet sales director.
"We took some very bold decisions when launching this car and how we’ve approached tackling the challenges of reducing whole life costs, SMR costs and National Insurance contributions, plus minimising the benefit-in-kind taxation for company car drivers.
"It wasn’t easy to do, but it was the right strategy and I’m encouraged by the sales results we’ve achieved and the very positive feedback from our customers and the new business we have brought in.
"With the new whisper quiet 1.6-litre diesel now launched in Astra, and much-improved availability of Mokka, we expect another strong year for Vauxhall in true fleet."
