I'd guess that as it is turbo charged, the torque curve will be reasonably flat, the "tba" quote on the VW configurator gives you a lot of confidence - not, especially if like me it looked like I would end up with that engine - ie buying a car with "tba" engine parameters! I have not fully investigated the impact generally when reducing the displacement of a turbo charged engine while retaining its maximum power output, but I'd guess torque might suffer.
