Opel/Vauxhaul has already won Britain's car of the year award for the regular model.

Now the company is preparing an "ecoFLEX" 2.0L diesel version of the car that is rated for under 140 g/km of CO2, or 5.2 L/100 km (45.2 mpg US) on the NEDC (urban/sub-urban European drive cycle - see Wikipedia for details).

Mods include:

• adding panelling under the fuel tank

• lowering the body 10 mm

• adding a flexible front spoiler lip

• reducing upper cooling openings

• these aeromods result bring the CD value down to 0.26, making it one of the most aerodynamic sedans in the world

• optimized gearing and final drive ratio on this six-gear manual transmission

• specially-designed Michelin Primacy HP tires

• shift recommendation dashboard display

And it's not exactly a slouch of a car, either: "The Insignia ecoFLEX sprints from zero to 100 km/h in 9.5 seconds and reaches a top speed of up to 221 km/h."

And it shore is purty, if you ask me!
