INSIGNIA ecoFLEX Sports Tourer with less than 140g/Km CO2

Vauxhall didn't miss to make the Sports Tourer greener, too. More power, less fuel consumption, less CO₂ . Looks like these engines don't have limits and everything is inside the software. We are much eager to see how an enormous 2.0 liter 160bhp estate car will manage to make 826 miles with one tank of fuel.

Following the success of the Insignia ecoFLEX hatch and saloon, the Insignia Sports Tourer now takes the green-hued limelight with an ecoFLEX version providing company and private buyers with significant reductions in running costs, without sacrificing performance or practicality.

With a combined CO₂ figure of just 139g/km, the ecoFLEX Sports Tourer drops four BIK tax bands to 18 per cent for company car drivers, compared with the regular CDTi Sports Tourer. And with a 12.3 per cent improvement in combined fuel consumption (53.7mpg vs 47.1 for the regular model) drivers can enjoy a filling station-free range of up to 826 miles.

But as with all Insignia ecoFLEX models, parsimony has not affected its performance and driveability.  Retaining the 160hp, 2.0-litre CDTi diesel seen elsewhere in the range, the ecoFLEX Sports Tourer still achieves a top speed of 134mph and will sprint from 0-60mph in just 9.3 seconds. A healthy slug of torque (up to 380Nm with overboost, to be precise) also allows it to pull slightly higher gearing, thanks to a revised final drive ratio.

A raft of aerodynamic changes is responsible for the ecoFLEX Sports Tourer's enhanced efficiency. Modified front air inlets feature, as do two under-body spoilers which direct air over the rear axle, reducing drag and lift. The upper front grille has also been closed, while the ride height has been reduced by 3mm at the front and 14mm at the rear. Specially developed low-resistance tyres and aero fins fitted to the rear screen complete the package.

None of this has dented the ecoFLEX Sports Tourer's practicality, of course. A capacious, 540-litre luggage area (rear seats up) matches the best in class, and is complemented by 40:60 split rear seats incorporating a ski-hatch, which fold to liberate a maximum capacity of 1530-litres.

ecoFLEX Sports Tourer prices start at £21,515 for the generously equipped Exclusiv model, and extend through S and SE trims to the Elite Nav at £27,750.
