What is usually left by the wayside in these conversions, however, is fuel economy. High performance tuning company 9ff has decided to tackle that angle, in addition to their stable of power modifications. When you think about it, many of the same modifications done to increase the acceleration of a vehicle can also increase its efficiency, mostly by reducing weight. 9ff has started with a Golf 1.9 TDI, then fitted lightweight components wherever possible and changing out the wheels and tires for low-rolling-resistance models. The progress of the vehicle can be tracked as part a ten-part segment on Auto Motor und Sport TV, which begins airing on May 6th. Click here for their own page dedicated to the project.
