Title: Biturbo
Post by: mikeok on 19 October 2014, 20:09
Iv ordered R the other week to replace my GTI..threads been done I know but also ordered a new Passat estate Biturbo tdi last Friday to replace my wifes Alltrack.  Cant wait to drive this 4 pot twin turbo Tdi with 240bhp and 500 nm. There was alot of chatter at the dealers that they are hoping VW would drop the engine in to a GTD at some point..what a Golf that would make..im not sure my self that vw would do this however...big leap..

They couldn't feasably drop this engine into a Golf and still call it a GTD. With the wrong tyres (Bridgestones), traction is already piss-poor from a standstill in a GTD, adding more power and torque without giving 4WD isn't going to change the 0-62 time (that is always quoted) significantly for the better.

It would also be significantly more expensive than the GTI and be a bit more powerful - have you seen the price difference between 2WD Passat 190TDI ultra and the 4WD Bi-turbo variant? Its about £5100.

It needs to be 4WD to put that power and torque down in anything less than 4th gear, and at the price it'll cost it will end up being a diesel companion to the R and not the GTI (which is exactly what is rumoured to be happening in the not too distant future). It'll be an R-D, a GTD-R or something similar.

Yes spot on im in total agreement with that torque it would not get the power down.
There is a large jump in price as you said but some of that is the equipment level is higher in the 240 such as full LED head lights etc..almost went for the 190R line but just knew I would be driving it thinking...I wonder what the 240 is like.
Its a heck of a engine though. ? Its in line with the 330d and c350cdi but only a 4 pot so lighter. I dont think theres another one like it as far as im aware. I guess with the constant chase for emissions its the way to go.?

Yes, it may be about the emissions. My DTUK boxed GTD is supposedly 240PS (will be thereabouts), and it is a sod to get the power down in anything below 4th in the wet or 3rd in the dry. My mpg hasn't appreciably dipped since adding it, so CO2 should be about the same, but who knows what the NOx or SOx are doing when you push on and see the oil temp climb.

Perhaps if it's not the emissions, but more to do with VW being supremely confident that even an abused GTD with 240ps will still have a clutch, injectors and turbo that last the distance in the Biturbo variant.

You are planning on remapping the passat I hope, for scientific purposes at least see what you can get out of the beast for use old black pump people who may one day return... :smiley:

I do think a 4WD GTD would be a winner. Faster than a GTI and 40mpg if driven hard, 52mpg doing 80mph on the motorway. It would make far more sense to company drivers as I can't see the residuals on it beating the 60% GFV after 3 years of the current R - purely because nothing gets above 60% unless it's severely limited in it's manufacture, it's unsustainable.

At that point you'd have 3 year old models selling for 80-85% of RRP by the time the dealership gets their cut, and who wants to buy a 3 year old car for 2 grand less than a new one can cost with discount?

I think once we are at that level of retained value at 3 years you'd kiss goodbye to any discount on a new one as demand would just be huge.

I think if it doesn't happen, that will be the reason...

Not planning on really but with 2x turbos it will have lots of possibilities.
Got a email from my dealer today to say the brand manager has just got back from the launch in Greece and said the biturbo was "amazing" got sli order number today also so roll on March..

Not even a cheeky dtuk box? Lol
Title: Re: Biturbo
Post by: mikeok on 20 October 2014, 20:21
Ok ok ...maybe lol.
I did find it a bit of a pain on my GTI tho due to the sensor underneath. ? Will depend on the location of everything I guess.
On another positive note the R I ordered 2 wks ago has come forward 7 wks to first week of feb for build....so im happy. :laugh:

Yes admittedly thin arms are a prerequisite of the tuning box lol but I think the diesels have less sensor points I think. You mapping the R?

Yes, plugging in the DTUK TDI box is a doddle, everything is on top, under the plastic engine cover. I probably won't get the R box, i'll be happy enough just to get some decent traction*.

* I sent an email to German VW customer services today asking why they haven't learnt the lessons of 4 cars ago for me - Bridgestones offering poor traction and grip (my MK5 also tramped badly as it had Bridgestones), and smeary wiper blades suffered on the last 4 cars until a Bosch Aerotwin option was available. I provided my R order number and asked if there was any tag they could apply to my order to ensure I don't get Bridgestones.

Let us know if you get a reply from then on that 1..do the Bridgestone come on the 18" or 19"...or both do you know?

Thanks for the info on that. May be a while b4 dtuk bring out a box as its so new so will see. But should be easier yes.
And with the 4Motion it will take the extra no problem.

Bridgestones are possible on both wheels, but on 19" wheels it is almost a cert you will get Bridgestones it seems (from the R forum). Whether Bridgestones have been a favourite 19" since we were able to get GTD and GTI with Santiagos I don't know (maybe a few people on here with them can shed some light?), perhaps Bridgestones becoming more common (as VWs preferred rubber supplier) is a recent development since the R was made available?

I'll not suffer Bridgestones this time around. If neither the dealer nor VW can help me avoid them getting on my R, i'll be putting my hand in my pocket and getting some Michelins from Costco put on (you can order in Supersports, not sure how much they charge for those over PS3s) and the Bridgestones will be going on Gumtree or the buy and sell section here.

Yeah Bridgestone not great. I have P zeros on my GTI and happy with them. 19" btw.

My 19s came with Pirelli P Zeros too. Grip wasn't amazing but the worst thing was the fronts were worn after 14k! The Dunlop sport maxx rts that I replaced them with are much better at gripping.

@MH someone made a good comment about getting the dealer to swap before you pick up the car. I'm sure if you have a good relationship with them its something they would do. Saves all that hassle.

Yes, it was mcmaddy - we both use the same dealer (and even the same salesman). If there's 2 Rs in around the same time on 18" wheels then it's a possibility to get the wheels swapped if one has Bridgestones and the other doesn't. Just trying to stop their fitment in the first place if I can, by letting VW know that Bridgestones are crap and so are the wipers they fit OEM.

btw I can recommend pilot super sports had them on my 335i and they were great..

I bought the Bosch aerotwins soon after taking delivery of the car last September and they are still in the box. I got the screen coated in gtechniq stuff and just persevered with the original wiper. It's only the passenger one that's starting to go.
