BlueMotion is Volkswagens branding of a new and economical series of engines. These engines represent the most efficient and economical vehicle in each of Volkswagen’s car ranges. Set to make its debut on the Polo, the BlueMotion brand will soon expand with the announcement that the Passat BlueMotion is to be unveiled at the Geneva Motor Show in March.

Applied to the Polo, BlueMotion comprises modifications to an already efficient diesel engine mated to a low kerb weight, improved aerodynamics and longer gearing. The result is an official fuel consumption figure of over 3.8 litres/100km (72mpg), a potential range in excess of 1100 km (700 miles) and a mere 102 g/km of CO2.

The Polo BlueMotion throws efficiency into sharp focus. At its heart is an advanced 80 PS 1.4-litre, three-cylinder TDI engine fitted with electronically controlled, high-pressure direct injection. A variable geometry turbocharger is added to provide high levels of torque from just above idling speeds and improve responses. The modifications increase the engine’s output and overall efficiency to allow greater performance while simultaneously using less fuel.

Despite its keen focus on efficiency, the Polo BlueMotion remains a usable everyday car. It will accelerate from 0 to 100km/hr in 12.8 seconds while returning an official 102 g/km of CO2.

Continuing the theme are the Polo BlueMotion’s external modifications. Evolved through work in the wind tunnel the unique alterations improve aerodynamic efficiency. Function effectively dictates the Polo’s form. A unique front bumper sits below a re-designed grille section to reduce drag. At the rear a pronounced spoiler mounted on the trailing edge of the rear window smoothes airflow further. Finally, a set of 14-inch ‘Jerez’ lightweight alloy wheels sit at each corner fitted with 165/70 tyres that reduce rolling resistance. In total the Polo BlueMotion weighs 1,084 kg.
