New Golf BlueMotion unveiled at Geneva Motorshow - 99g/km CO2

The BlueMotion version of the new Golf boasts significantly better fuel consumption and emissions figures than its predecessor, despite matching its performance. The new car, which made its debut in Geneva, is the first Golf BlueMotion to feature Stop-Start technology.
 
The BlueMotion version of the new Golf boasts significantly better fuel consumption and emissions figures than its predecessor, despite matching its performance. The new car, which made its debut in Geneva, is the first Golf BlueMotion to feature Stop-Start technology.

The automatic Stop-Start system operates through the clutch pedal. When coming to a halt at traffic lights, for example, the driver depresses the clutch and selects neutral. When the clutch is released the engine shuts down and a ‘Stop-Start’ symbol illuminates on the multifunction display. To move away the driver simply depresses the clutch again to select first gear and the engine automatically restarts. The system can be deactivated.

 
Regenerative braking is another feature of the Golf BlueMotion. It helps to use energy that would otherwise be lost during braking. In deceleration and braking phases, the alternator’s voltage is boosted and used for bulk recharging of the car’s battery. Thanks to alternator control, it is possible to lower alternator voltage, for example during acceleration or driving at a constant speed. It is even possible to switch off the alternator entirely which reduces engine load and improves fuel consumption.

 
All Golf BlueMotion models have a standard Diesel Particulate Filter (DPF) and comply with Euro V emissions legislation. Other aspects of the BlueMotion package include longer gear ratios (for third, fourth and fifth), very low rolling resistance tyres and aerodynamic refinements.
