Hybridizing A TDI?

[CowPatty]

Are there any options for hybridizing a MK4 Jetta? it seems like something someone would have tried at some point...
I couldn't find any kits (not surprised) but I wonder if you could gut a junk yard hybrid and figure something out...
crazy idea...
any thoughts?

 

[T1MMBOJONES]

put a tesla badge on it maybe?

 

[CowPatty]

lol it'd be a start...

I've often thought of a hub motor in both rear wheels, with a battery and controller in the trunk. The controller would, for simplicity, independently sense acceleration and braking, then apply additive or regenerative braking forces respectively. Alternatively, it could be tapped into the wheel speed sensors to determine how much input is needed. This would also allow for anti-skid functions, although I'm sure with GPS in the controller and motor sensors, lots of functions could be figured out without having to connect to the ECU.

Same here, but with the controller sitting in the driver's seat. Just an extra throttle stick, kill the engine during shiddy traffic, and bump start when the road clears up. Battery range would only need to be 20-30mi i figure.

The 48v alternator/hybrid motor could be an option. There's a guy on here who is using one of them in a swap,and there are some people who have controllers set up for them.
It would take some creativity to get it done well.

Ummmmm...y'all are not going to get away without speaking over CAN between the EV part and the TDI part. A control code set is going to be needed. It jus' is not quite that simple.

Probably best to take an aero, light hybrid car and remove all the battery schtuff, and install a TDI. A Gen1 Insight comes to mind.

I've seen someone with a tdi insight swap before. I think this is it: https://www.insightcentral.net/threads/swapping-a-tdi-engine-into-a-1st-gen-insight.24196/

 

[braddies]

Mmm, TDI swapped Prius..

I've got one, not diesel, but factory built, and has the worst of both worlds.
Haul around a few hundred pounds of battery, charger, coolant pumps, thermocouples, heaters, thick gauge wires for the high amperage and thick insulation on those due to the high voltage, all for 40 miles of summer range, 25 in the winter before running as a "CVT" transmissioned, internal combustion engine powered Corolla sized econobox with a small gasoline tank (space eaten by batteries), complexity of dual motor/generators, and the clutch packs needed to transition from one to the other, plus the evap controls, cat converter, engine wear due to constant stop-start cycles.

Nah, pick one or pick the other. This mugwump, can't-make-up-my-mind, compromise of hybrid (whether series or parallel) isn't worth the fantasy day-dreaming.
Yeah, I'm looking at getting into diesels again.

Or go even lighter with a slightly more entertaining car...B5.5/BHW in an Esprit.

ive long thought about mounting a tesla rear drive motor from like a standard RWD model 3 in my car (in the rear subframe), then fitting the battery pack to my floorboard or using a battery pack from the jetta hybrid or something. plus it would make it AWD

if i won the lottery im sure i could make something work...

if you win the lottery you could import one of these instead. licensing it may be an issue but hey you won the lottery right??

if im reading that correctly, it isnt a TDI hybrid, but rather a plugin hybrid AND then a TDI. both wagons.... but still we get none of them here. a real shame

i didnt read it to be honest, but breifing it im thinking you may be right. to me when i see kW i assume electric but thats how they measure ponies aint it? i thought the audi q7 e tron or whatever its called had a tdi/plugin option but the articles i find pertaining to it all almost seem like ai wrote them....i also stumbled upon a e/tdi golf concept from 08 but not sure how credible it is either....

VW has experimented with hybridizing the TDI's before, look at the XL1 for the only production example afaik. there have been test mules with golf's etc otherwise i believe

but yes, they measure HP in KW over there, also in ps sometimes

i know what im buying once i win the lottery now....

 

[lemoncurd]

i know what im buying once i win the lottery now....

dont forget what we could have had..... im quite upset we never got the XL1 as a full fat production econobox. even a watered down version. it's a damn shame imo

anyways, ducati wanted to take a swing at it too, and made this beauty

[lemoncurd]

yeah if i won the lotto, i would spend every last dollar making the VW XLsport a thing for me to drive around, and buying an XL1

You'd probably run out of space. I've seen some hybrid engine bays and the motor is CRAMPED! My knuckles twitched just from looking at it. Not to mention all the extra weight. Why not try shooting for the world's first fully electric MK4 jetta instead?

 

[CowPatty]

it wouldn't sound as good

I've often wondered why we don't see diesel hybrids. I love the idea. A few things:

Electric power steering rack would simplify the conversion.
An accusump or similar might be a good idea if the engine starts/ stops frequently.
The main benefit of a hybrid is regen braking - with that in mind, on decel, you'd want to de couple and shut off the tdi (don't need compression braking stealing the main benefit).
A coolant thermos from a Prius might be good to keep the coolant hot - I even wonder if an electric coolant heater just to keep the engine near operating temp would be necessary - on cold enough days if watched the temp gauge drop in stop and go on my ALH.

I love the rear motor and bump start idea, would save replacing starter motors every 6 months. Ideally a DSG could take care of this automatically however I suspect they need to be running to have hydraulic pressure for the clutches.

It would be a cool project. Probably the easiest way as others have mentioned is to swap an existing hybrid.
