As in its application in Audi's S3, the 2.0-litre has been detuned for Australian conditions. The Audi's mill was putting out 195kW and 350Nm overseas but was launched here in 188kW and 330Nm guise. The Golf R is said to share the same power, being released here with 188kW but as yet a torque figure hasn't been announced.
Our extreme conditions mean reliability is the concern, but you'd have to guess that poor quality fuel might also have something to do with it. Fuel consumption may also be affected, but reports are that it won't be a great jump in fuel use. With a 0-100km/h time of 5.5 seconds when mated to the DSG for the 199kW version, we might see a few tenths added with the power loss.
CarAdvice will keep you updated on the torque figure as soon as it's announced.
