As no-one's picked up my comments in previous threads when comparing TDIs and TFSIs etc. over the past weeks... Does anyone know where I can find info on which gearbox is fitted to 140TDI, 170TDI , 2.0TFSI and S3 with respective ratios and final drives? I'd like to try and do some calculations to once and for all work out the on-the-road comparison of these cars, because the endless debate about torque curves and power output of the engines especially comparing TDI to TFSI is getting on my nerves. What matters is torque/power to the wheels, that's what makes the car move forward. We did the same calculations at University, but it was more than 10 years ago now so it may take me a while (days/weeks) to get them right but I'd be happy to post some graphs when complete. Cheers.
