All of the engines in the new Golf now use less fuel than before. With 3.8 liters of diesel per 100 kilometers, the Golf BlueMotion is even the most economical car in its class. However, those interested have to wait a little longer for the true avarice golf. The first Golf with liquefied gas is planned for 2009.

E.There are miscalculations that are not that bad. When VW began, its models were particularly fuel-efficient "To launch BlueMotion ”models, the managers planned small numbers. After all, not only did consumption drop, the price also rose, and changes to aerodynamics and gear ratios were necessary. But that didn’t bother the customers, on the contrary: After the Polo and Passat BlueMotion, the Golf and Touran were added, and VW boss Martin Winterkorn still says: "We can’t keep up with the delivery. "

A BlueMotion version was firmly planned from the outset for the sixth generation of the Golf. Although it will not be at dealerships with the other models on October 10, it will set a record when it goes on sale in summer 2009: With 3.8 liters of diesel per 100 kilometers, the Golf BlueMotion will be the most economical car in its class. The carbon dioxide emissions are 99 grams per kilometer and thus well below the EU upper limit of 130 grams, which every manufacturer must achieve on average from 2012 onwards.

As with the predecessor, a longer gear ratio, which lowers the engine speed, and low-friction tires, which reduce rolling resistance, are responsible for the modest thirst for diesel. In addition, the Spar-Golf VI has a newly developed common rail diesel engine. Not only does it run much quieter, with a displacement of 1.6 liters it is also smaller than the previous 1.9-liter model. With 105 PS, however, the same power is available, and the value for the greatest torque has also remained the same at 250 Newton meters.

The fact that the new Golf BlueMotion consumes 0.5 liters or 11.3 percent less than its predecessor is primarily due to the automatic start-stop system that VW is installing in a car for the first time. As with some BMW and Mercedes models In future, the Golf engine will simply stop at the red light and start again automatically as soon as the driver depresses the clutch.

There will only be a 2.5 liter consumption in the Golf VII

At the moment it is not yet possible to try out how comfortably this works – Mercedes still does without the automatic start-stop system in its diesel engines, because the diesel is more rough than a petrol engine when it starts. You don’t want to expect that from customers – BMW has no problem with that, and the difference between diesel and gasoline engines in the cars from Munich doesn’t matter.

VW will also install the new four-cylinder diesel in 2009 in the normal Golf without the BlueMotion package. In addition, the engine is supposed to provide the basis for a new three-cylinder with a displacement of 1.2 liters, which will definitely be used as an economical engine in the VW small cars, and later perhaps also in the Golf. Martin Winterkorn believes that drivers can get used to the three before the decimal point in the long term. “There will be plenty of these types of cars, whether they consume 3.2 or 3.7 liters.” And that without the support of an electric motor, as provided by the hybrid technology favored by Toyota.

VW is also working on a solution like this, a few months ago Winterkorn presented the VW Golf Twin Drive, which 20 customers will try out in Berlin next year. This Golf can drive electrically up to 50 km / h; if it needs to go faster, the conventional motor is switched on. VW expects an average fuel consumption of 2.5 liters, but the technology will not be ready for series production until the seventh generation of the Golf.

VW uses that for gasoline engines "Downsizing ”continues, reducing the size of the engines while maintaining or increasing output. The 1.4-liter TSI engines will soon shrink to 1.2-liter displacement. Even the Golf R32 feels the new modesty. Instead of a 3.2-liter six-cylinder, an extra powerful version of the two-liter four-cylinder from the GTI with turbo and 265 hp will be used in the top model.

The new GTI, which will be unveiled at the Paris Motor Show at the beginning of October, will be awarded a surcharge of ten to 210 hp and will be available at dealerships in spring 2009. Anyone who wants to drive particularly cheaply with gasoline vehicles will also receive an offer in 2009. Then VW will bring the first Golf to use liquid gas. Price per liter currently: 70 cents.
