The difference between the VW T6 TDI340 and TDI400

Getting a new VW T6 and don’t know what all the jargon is about? Hopefully we can help!

Background: the 2.0Litre turbo-diesel engine is available in two ‘output level’s’ (VW calls them ‘output levels’ but from what I can ascertain this relates to the amount of power in the engine).

The TDI340, 103kw, 340Nm

Average fuel consumption from 7.2L/100km.

The Bi-turbo TDI400, 132kw, 400Nm.

Average fuel consumption from 7.6L/100km.

Basically, the TDI400 has an extra turbo giving it more power, which means it also uses a TINY bit more diesel.

Which do you need for your campervan? Either! The TDI340 is perfectly fine. “You would get the TDI400 if you want some extra “oomph””. (straight from the mouth of our VW contact!)

      Hi Brian, I did not know the answer to this so have just asked our contact at VW who has said: “Judging by VW’s service program, not too much difference – over the first 5 services (which are every 15,000kms or 12 months) the TDI400 is only $16 or $17 more per service than the TDI340 engine.”

    There are not two T6 Transporter vans. There are three. My Achtung Camper is a T6 but it is a TDI250. Although it is a diesel with a turbo, it produces only 75kW of power and 250Nm of torque. VW claim an average fuel consumption of 7.0L/100km. In Germany there is an even less powerful diesel T6 van available and several petrol models or “TSI” vans. Here in Australia we get only the three vans: TDI250, TDI340 and the TDI400. (The Multivans are also available with a TDI450 engine.)
    In Australia Volkswagen market the TDI250 as the “Runner”. My 2016 model TDI250 “Runner” cost only $32,990 new last year. It has everything that the TDI340 has except for the electronic locking differential and the power of the TDI340. Yet, it is around $10,000 cheaper and only comes with a 5-speed manual transmission, not the 7-speed DSG automatic.
    Around town it is perfectly capable. When I drove to Geelong to have it fitted out by Achtung it was fine on the open road. On the way home to Toowoomba with all the Achtung camping fit-out in it, I was able to cruise at 120km/h and I still had power to overtake 36m road trains north of Goondiwindi. (I used to have a 1973 1600 Kombi camper and that would have been impossible.)
