BTW, if you have any thoughts about how a TDI should be driven, go down to a VW dealership that has a 2014 Touareg TDI in stock with the new 8 speed automatic.
Get in, turn on the ignition, don't start the motor, and hold the throtttle to the floor for 10 seconds. Turn the ignition off. Now start the car by putting your foot on the brake and turning the ignition on. You have now reset the transmission to learn how you shift and drive.
Drive and accelerate the 2014 with the 8 speed automatic as gently on the throttle as possible, and I do mean gently. Lift the throttle at 1800rpm for 1st gear, 1900 for 2nd gear, and about 1700 for 3rd, 4th, 5th, 1700 for 6th, 7th, and 8th gear. You are force shifting that automatic transmission on level ground by doing this.
It should shift into 7th gear (overdrive) at 41 to 42 mph and 8th gear (another overdrive gear) at 53mph.
Note the rpms drop. That VW engineers enable this car to shift at such low RPM's is a testament to how they planned this SUV to be capable of being driven in such an efficient manner. Fuel is very, very expensive in Continental Europe. They engineer and drive accordingly.
