BlueMotion is VW's new ultra-economical brand that will be applied to all of the most fuel-efficient cars in its range.Not just a boot badge, the Polo BlueMotion's 1.4-litre turbodiesel has been modified to give greater torque at lower revs.
The gearbox has also been altered with longer gearing so the engine spins at lower revs when cruising.
VW has been busy lightening the Polo to get its overall weight down to 1,084kg, while some aerodynamic modifications to the front bumper make it more slippery through the air.
The result is Polo that returns 72.4mpg and produces 102g/km of carbon dioxide.
Performance is not unduly compromised, and the Polo BlueMotion manages 0-62mph in 12.8 seconds and 109mph.
VW will unveil the Polo BlueMotion at next month's Geneva motor show before it goes on sale in the UK this summer.
