Mmmm, D5 V6 or P400 to replace D4?
I'm interested in any experiences too.
I know that it's very early days but no harm in asking. Anyone out there with a P400 done any towing yet?
What were you towing, (size and mass) how did it cope and did you measure fuel consumption.
Thanks

+ 2016 D4 TDV6
a few on the FB All new defender owners group in the US using them for towing, some horrendous figures being quoted
in terms of fuel return .. to late for me however as i now have my P400, but if you are ordering now i would place my
money on the D300 MHEV with the straight six as most probably the right tool with at least some reasonable fuel economy
Yanks worrying about fuel use🤣
..what sort of figures are they quoting??...
I don't do farcebook...
..ok I did a search and yes some high figures are being cited for heavy towing..up to 3.7t.
Seems a bit odd as our 250kw D4 has never exeeded 16l/100klms when towing up to 3.5t....and on hilly terrain too. Mind you the 290kw Defender has 3l/100klms better lowest fuel consumption so I guess in the end it averages out cause you don't tow all the time.
Yeah that's part of the dilemma though I think I have ruled out the D5. Then there's the P400 or P300, with DPF and AdBlue.
I will have a look at the video later and do some conversion on the values quoted. I never doubted that the P400 has the power and torque, it's just a case of eyes open as far as the fuel burn is concerned.

My D4 does 18 to 20l/100 towing just over 3T,pretty windy that day,but it did similar on the return trip,over 700K.
I would expect P400 to use more.
I did see a tow test using the D240 in the lighter D5,and it wasn't impressive at all,but i believe that engine has gone.
The real issue for the petrol is the small fuel tank,a real nuisance when towing.
As the spare tyre is on the rear,hopefully the aftermarket guys will sort out a larger tank.
Carrying petrol in jerry cans and decanting is not the safest thing to do.
The 6cyl diesel would be the best towing option,no doubt,by far.
Some may say the Diesel is complicated,but so is the petrol,it isn't something like the Y62 engine,as an example.

Y62 is a pretty sophisticated engine:
The*VK56VD*is a 5,552*cc (5.6*L; 338.8*cu*in) 32-valve, DOHC, Direct Injection Gasoline (DIG) aluminum-alloy V8 and features*Nissan's advanced*VVEL*(Variable Valve Event & Lift System). The direct injection system provides better wide-open throttle performance and improved fuel economy and emissions performance by reducing engine knock, improving combustion stability and controlling injection more precisely.
Block..piston and bores also have special chemical treatments etc.
One good aspect is that like the 200s V8 it is vastly understressed aka American style no 'subs for cubs' so there's huge capacity for more power.
