Driven by hypermiler Felix Egolf, a former Airbus pilot, the car achieved an average consumption of 3.46l/100km; around 10% below the official figures.

Mr Egolf’s tour started in Lucerne on 6 April from where he travelled to the Opel headquarters in Rüsselsheim via the Black Forest. In Rüsselsheim, he stopped for a chat with Vice President GM Global Propulsion Systems – Europe, Christian Müller.

“The fuel gauge in the Insignia still showed that the tank was almost full when Felix Egolf arrived in Rüsselsheim. He managed to complete the first 429 kilometers with an average consumption of only 3.2 litres. It is great that he managed to crack the 2,000-kilometer mark,” said Mr Müller.

The hypermiling tour then took Egolf to Münster, Oldenburg and up to Cuxhaven on the North Sea coast. The return leg saw him pass Hanover, Kassel, St. Gallen before coming to a successful end in Zurich on 8 April.

“I have wanted to crack the 2,000-kilometer barrier for some time now but I couldn’t find the car to do it. The excellent aerodynamics of the Opel Insignia combined with the Eco Contact 5 low-rolling resistance tyres contributed to this outstanding result. This hypermiling tour with the Opel Insignia also shows that anybody who has an anticipatory driving style can easily equal or better the official consumption figures. Anybody can be a hypermiler,” said Mr Egolf.
