Earlier in this thread Lutz touched on VW going Hybrid in the new series Toaureg (due 2010).
Initially I thought that like Lexus, VW's maximum towing figures would be reduced due to the weight of the batteries eating up the payload and that we would end up with a 2000kg max tow (like the 450H), rather than the current 3500kg.
It appears however that the range is to keep it's 3500kg rating, as well as being better performing during acceleration, top end speed, fuel consumption and CO2 emissions, when compared to the current range.
If the figures prove to be correct, that is technology moving in the right direction, however I don't do enough town/city driving in mine to justify the change over.
