Interesting tow cars
Re: Interesting tow cars
On the rather shaky premise that a Defender and a old-shape Wrangler are probably equally well assembled and have similarly advanced mechanicals (i.e. not at all and prehistoric) think more like 50% loss - yes really. A mate of mine ran a workshop modifying Wranglers and the 200 bhp crank figure was more like 100 bhp at the wheels on the dyno.
Re: Interesting tow cars
There is a towing channel on YouTube where they tow 6 horse horse boxes and other such big stuff. It’s amazing how much some of the dually equipped trucks can tow in America. If you are doing 40mph full throttle in a 450hp diesel pick-up, it seems a bit too portly to me
Towing with a 5th wheel must feel completely different though.

Re: Interesting tow cars
I’ve read a 33% measured loss for a V8 petrol with the same gearboxes as mine but I don’t know what axles it had, probably standard Rover axles.JLv3.0 wrote: ↑Thu Sep 26, 2019 9:33 am On the rather shaky premise that a Defender and a old-shape Wrangler are probably equally well assembled and have similarly advanced mechanicals (i.e. not at all and prehistoric) think more like 50% loss - yes really.

I’m intrigued now so I’ll find a graph from somewhere.
The Humvee went from 230hp to less than 100ho at the tyres.

Re: Interesting tow cars
What about an XC90 V8, I believe a certain member of this establishment used to have one.
Not sure if Mr Yu still has his or not, would probably make light work of a car trailer and sound quite nice whilst doing so.

Re: Interesting tow cars
Changing the drivetrain loss to 30% I get 88mph as theoretical top speed. For comparison, plugging in numbers for the Touareg, I get 141mph vs. VW's quoted figure of 144mph. So that part of the calc all feels about right within a couple of percent.
Re: Interesting tow cars
That seems far more likely speed wise.

I can't believe I didn't think of that. It's on my list.

They also did the Touareg with the W12 for a while, but only LHD sadly.

NIce, from someone looking at the SQ7 recently.
As per one of the PH comments on that link, what about https://www.autotrader.co.uk/classified ... 9051899048 with a towbar?

for £8.5k less from the same dealer, with only the 240bhp and 400lb ft to push you along.
Actually, that's almost exactly half the power of the V12

I remember being a Wrangler 4.0, made a lot of noise on kickdown but didn't really move.

Well, the V12 is just two A4 engines cellotaped together.
If rarity (potential costs/aggro) puts you off the V12 but the V6 doesn't have enough oomph, how about this?

Re: Interesting tow cars
If you want a silly engined VAG and a V8 is too small but a V12 is too big, and a normal V10 is not enough, how about a Touareg R50 https://www.autotrader.co.uk/classified ... 8080942023
Frankly the Q7 V8 TDI is far more appealing though, and I don't like Q7s. Back to the Allroad BiTDI for me.

Would that 2015 Q7 have the Porsche Diesel engine by any chance ?Jobbo wrote: ↑Fri Sep 27, 2019 9:05 am If you want a silly engined VAG and a V8 is too small but a V12 is too big, and a normal V10 is not enough, how about a Touareg R50 https://www.autotrader.co.uk/classified ... 8080942023

Re: Interesting tow cars
I have no idea - I didn't even realise they kept making a V8 TDI that late. This Autocar article from 2009 (when the Q7 was facelifted) says the 4.2 got a power increase, so it may simply be that they kept fitting the same slightly tweaked Audi engine from 2009-2016: https://www.autocar.co.uk/car-review/au ... -v8-tdi-seNathan wrote: ↑Fri Sep 27, 2019 9:42 amWould that 2015 Q7 have the Porsche Diesel engine by any chance ?Jobbo wrote: ↑Fri Sep 27, 2019 9:05 am If you want a silly engined VAG and a V8 is too small but a V12 is too big, and a normal V10 is not enough, how about a Touareg R50 https://www.autotrader.co.uk/classified ... 8080942023

ETA: Porsche used the Audi engine anyway, not sure how they modified it themselves so it's possible Porsche's mods made it into the Audi version I guess...

Re: Interesting tow cars
Looks quite subtle compared to a Q7...

Re: Interesting tow cars
Panamera V8 tdi was supposed to be quite special. There was an owner on readers cars in Pistonheads.

When did the current panamera appear, 2016 was it?
