What is it?
Massaging every single extra kilometer of travel out of a litre of diesel is increasingly the name of the game for European carmakers. So every trick in the aero book is being exploited to help cars slither down the road in a more Co2-friendly fashion.
So, like its hatchback sister, the Insignia EcoFlex Tourer wears a full complement of wind tunnel bling, including under-body spoiler. These direct air over the rear axle, which Vauxhall says reduces drag and reduces rear end lift.
The car’s upper front grille has also been blanked off, the rear screen fitted with ‘aero fins’ and the ride height lowered (by 14mm at the rear and 3mm at the front). Low-rolling resistance tyres complete the external package.
Mechanically, not much has changed bar slightly longer gearing and the Insignia gets the full-fat 158bhp 2.0-litre diesel unit, in contrast to other ‘eco’ models, which usually get de-tuned engines.
What is it like?
While the Insignia is a handsome machine, especially in Sports Tourer form, and has a stylish and well-made interior, its chassis really lacks a final polish, especially on broken British roads.
