Performance V70 2.4D and 6-speed question

Hello everybody, I would be interested in your experience with the 2.4D machine at the V70 as a (so far) non-Volvo driver. If I look at the weight of the vehicle, I assume that acceleration and elasticity are rather to be desired. Should one definitely prefer the D5? Also : Is there a six-speed gearbox at all with the V70 or is one limited to five gears? Thanks and greetings, Rob
