VW says its new Polo BlueGT, unveiled today at the Geneva Motor Show, combines dynamic performance with extreme fuel efficiency.

On sale in Europe from July, it uses ACT cylinder deactivation, the first time this technology has been adopted in a production Volkswagen.

The turbocharged 1.4-litre four-cylinder engine produces 140 PS, yet returns a combined cycle fuel consumption figure of just 4.7 litres per 100 km (around 60mpg) with a forecasted 108g/km of CO2.

On the seven-speed DSG transmission, fuel consumption drops to a forecasted 4.5 litres per 100 km (62.8mpg) with CO2 emissions of 105g/km. Top speed is 130mph and zero to 62mph takes 7.9 seconds.

At the heart of the Polo BlueGT is the first of the new EA211 series of engines. It also boasts multi-spoke 17-inch alloys and suspension lowered by around 15mm.

In the cabin, both driver and passenger sit on bespoke BlueGT sports seats.
