I'm also wondering if the 5spd 2.4 will be adequate particularly so as I live at five thousand feet. But, it appears the 2.0 turbo diesel closes the torque gap with the 4.0 so I may end up waiting a year for the 6spd diesel; I've driven the current VW 1.9 TDI through the mountain passes here and it will dust my 4.0 5spd. Interesting VW press release: "Wolfsburg, 04 January 2007 - Volkswagen unveiled the cleanest ever TDI engine. First test drives demonstrate the high potential of Volkswagen technology, which consequently reduce nitrogen oxide. In the VW Jetta a new 2.0 litre Common Rail diesel engine with a nitrogen oxide reservoir catalytic converter was used, which complies to the Californian emission standard "Tier 2 / Bin 5". These requirements are considered the most stringent worldwide. The first production run of the "Clean TDI" with nitrogen oxide post-treatment system will be made during 2008 in the USA. ..." Since DC is also part of the joint BlueTec diesel initiative, I am assuming DC will also be offering the 2.0 a year from now.
