Volkswagen’s bread-and-butter Golf and Polo ranges get an efficiency update with BlueMotion.BlueMotion was first launched on Polos sold in Europe in 2006 and the technology made its debut in the local VW line-up with the launch of the new Touareg in October, 2006. The rollout of BlueMotion on Polo and Golf precedes a general introduction across the VWSA catalogue. The BlueMotion package on Polo and Golf include new common-rail TDI engines with modified engine management software and reduced idling speeds, regenerative braking, low rolling resistance tyres, lightweight wheels, a stop-start system, a gear-shift indicator and more efficient dynamics. The Golf BlueMotion’s ride height has been reduced, too. POLO BLUEMOTIONThe Polo BlueMotion 1.2 TDI has a combined fuel consumption of 3.4 litres per 100km. Volkswagen calls this the “most fuel efficient five-seater in the world”; its standard 45-litre fuel tank could allow you to cover up to 1200km, it claims. The three-cylinder engine generates 55kW at 4 200r/min and has a peak torque figure of 180Nm from 2000r/min. It goes from 0 – 100km in around 14 seconds and has a top speed of 176km/h, Volkswagen claims. CO2 emissions are 89g/km. By comparison, the “regular” 1.6TDI has an average fuel consumption rating of 4.2 litres per 100km and CO2 emissions of 109g/km. GOLF BLUEMOTIONThe Golf BlueMotion, with its 1.6 TDI engine, is equally economical, consuming 3.8 litres per 100 km and emitting a mere 99 g/km of CO2. Its 55-litre tank could allow you to go for 1300 before requiring a fuel stop. This 16-valve engine produces 77kW at 4400r/min and maximum torque of 250Nm from 1500r/min. It ambles from 0 - 100km/h in 11.3 seconds and has a top speed of 190km/h. FUEL SAVER: Stop/start technology is standard on Polo and Golf BlueMotion. A FEW DIFFERENCESApart from the new engines, the cars appearances have also been slightly altered to allow for the aerodynamic enhancements.The Polo’s radiator grille has been reduced to a slit, it has a new front spoiler, new side skirts, a new bumper and new spoiler. Underbody components are more aerodynamic and 15-inch alloys have been subjected to wind-tunnel treatment for optimal efficiency. Similarly, the Golf sports a modified grille, bumpers and side skirts, 15-inch alloys and a roof spoiler mimicking that seen on the Golf GTI.Additional features include cruise control, tyre pressure monitor, front centre armrest with storage box and rear cupholders and front fog lamps for the Polo and a multi-function display with gear-shift indicator and chrome accents for the Golf.
