At next month's Frankfurt Motor Show, Volkswagen will be showing six of their high-mileage, low-emissions BlueMotion models and they have just released some details on the new Golf BlueMotion. Cutting right to the chase, the new Golf will be rated 52.3mpg (US) with CO2 emissions dropping to just 119g/km. Those figures compare to the standard Golf TDI's 46.1mpg and 135g/km of CO2.
Volkswagen accomplished this by modifying the engine management calibrations to reduce the idle speed, adding a particulate filter, and changing the gear ratios to lower the engine speed in third, fourth and fifth gears. The grille has been closed off, the underbody of the car has also been cleaned up and the whole body was lowered to reduce drag. Low rolling resistance, high pressure tires finish off the new configuration. The BlueMotion's base price of 20,615 euro is just a 315 euro premium over a comparable Golf TDI and German drivers will be able to pick one up before the end of the year.
First Facts on the Golf BlueMotion:
World premiere of the most economical Golf at the IAA
4.5 liter fuel consumption and 119 g/km CO2: New Golf BlueMotion sets environmentally-friendly benchmarks in the compact class Wolfsburg, 13 August 2007 - Volkswagen will be firing off the next salvo of its BlueMotion initiative at the International Motor Show (IAA) in Frankfurt. In total, six new models with technology that is as economical as it is environmentally friendly, will debut at the world's largest
car show. One of the highlights there: The new Golf BlueMotion. At just 4.5 liters of
diesel per 100 kilometers, its fuel consumption has been reduced by a full 0.6 liters compared to the original model. Similarly, CO2 emissions have been reduced from 135 g/km to 119 g/km. Actions taken on the BlueMotion make it so efficient that now distances of more than 1,200 kilometers are possible on just one Golf tank of fuel (55 liter). Market introduction of the Golf BlueMotion in Germany is scheduled for the end of this year.
BlueMotion fireworks: Besides the Golf, Volkswagen will be presenting five other BlueMotion models at the IAA
Details of the new Golf BlueMotion: After the Polo, Passat and Passat Variant, the Golf is now the fourth Volkswagen to wear the new BlueMotion environmental badge on its radiator grille and rear hatch that identifies it as the most economical model of the car series. The Golf BlueMotion is driven by a TDI with 77 kW / 105 PS and a hefty 250 Newton-meter of torque that has already achieved recognition as an efficient engine.
A software intervention in engine management reduces the idling speed of this diesel combined with a particulate filter and simultaneously improves its emission behavior. With longer gear ratios in third, fourth and fifth gears, engine speed levels are also lower while driving. These actions alone reduce consumption by about 0.2 liter.
Less apparent but no less necessary for a plus in economy are the thoroughly trimmed and thereby flow-optimized underbody as well as the nearly enclosed radiator grille. To ensure that the TDI engine still gets enough cooling air, the Golf BlueMotion has an effective dual fan. Thanks to aerodynamic design measures, including lowering of the chassis, the cW value of 0.32, which in itself is a good value, was further improved to 0.30.
In the hunt for every gram of CO2 Volkswagen is also relying on light-running tires, size 195 / 65 R 15, optimized for low rolling resistance; they are driven at higher air pressure, increased by 0.3 bar. When all of the modifications come together in the end product, the top speed of the Golf rises from 187 km/h to an electronically limited 190 km/h.
When it comes to equipment options, the Golf BlueMotion customer can choose between the Trendline and Comfortline. In addition to basic equipment, special Blue Motion specification is also on board. The base price of the Golf BlueMotion Trendline is 20,615 euro and this makes it just 315 euro more than the base price of a Golf 1.9 TDI Trendline. When adjustments are made for equipment options, the BlueMotion is even more economical than previous TDI versions with 105 PS and soot particulate filter. Besides the aerodynamic modifications already mentioned, standard equipment includes the Multifunctional Display Plus (MFA Plus) with gear recommendation arrow and a sports chassis. Thanks to its attractive price positioning, the purchase of a Golf BlueMotion already pays off from the first kilometer – and not just for the environment, but also for customers' budgets.
