Watch: 740 HP Golf R Has One Too Many (or Too Few) Cylinders Share Comments Depending on your perspective, this Golf R has either one too many or one too few cylinders. Either way, the 2.5-liter’s 5 cylinders is more familiar in an RS3 than a Golf R (oh, what could have been). Still, there’s a good reason for the RS3’s engine to find its way into this Golf R. In fact, there are 740 good reasons for this engine to be in the Golf R. Built by TheTurboEngineers, the engine achieves its lofty power goals thanks to a TTE700 turbo. All of which makes it powerful enough to hold its own against its bigger Audi siblings at the Race 1000 event in Germany. It may not sound quite as nice as a VR6, but those launches more than make up for that.
