After looking at the price of AGM-31 batteries I bet my car won't stay under the $7000 price range for long. But it should easily beat 70mpg and the 0-60 time

Edit:
About the $7000 budget I'd bet that alot of it will go to their Italian stylist + body work. Just speculation

I couldn't agree more!

Looks like TG is late to the party after all.

1984 Rabbit GTI TDI-M

Ok it's not exactly the same as what TG will be doing as this one was mechanically converted, but it's pretty close.

Nice find, Tas. I'm surprised he didn't post fuel economy figures. But then it sounds like it's not quite finished either.

Look for some slick aerodynamic tweaks - designed with help from UCLA aerodynamics professor John McNulty - that will include vortex generators and a flat undertray.

Oh no, not VGs please. I guess that's the bling part of aero, as there are way lower hanging fruits than VGs, but don't they look cool do they? They probably won't have a way of accurately testing them, not with their budget. Prof McNulty got access to a full scale wind tunnel though. So maybe, with some free wind tunnel time, we can dream of seeing a rabbit with VGs being tested in a wind tunnel on Top Gear. I highly doubt that will happen though. Wind tunnels just cost too much to run to give away time for free.

Haha, no surprise there. From what I've seen of TG, they always go for the shock factor (flashy stuff, or the exact opposite). Why would this be any different?

If EM does go this route and Basjoos agrees, I will donate my spare D15Z1 and some time over the summer to this project to get his car setup with a VX motor. It would be possible to push him over the 100MPG mark easily while still retaining an OEM drivetrain.

This was first done a lonnnnng time ago, search the vwdiesel.net forums using tdi-m for more info. That said, a tuned/intercooled 1.6L can make as much power as a stock TDI for way less cash. Honestly, they could've slapped a VNT/intercooler/Turbo IP for ~$500-1000, spent another $2k on a motor/controller/hardware to see electric rear wheel drive, and bought about 9kWh of Lithium Iron Phosphate that can put out a max sustained power of ~25kW and peak power of ~75kW. Since this initial $500-1000 would net ~50-60mpg driven "normally" and a ~8.5s 0-60, more than doubling the HP, along with the massive torque created at the rear wheels by an electric motor would allow for a sub 5s 0-60mph and ~35-50 miles of all electric range.

For the hell of it, yank the glow plugs, toss some spark plugs in there, along with a mesh heater and a TBI setup run offa MS&S for another grand, then rig it to add E85/water progressively as the diesel injected drops around ~5-6k rpm. Should be good for another 30-40hp up to ~7.5k rpm, and it would be the world's only plug-in hybrid electric turbo giesel, or dasser if ya like, powered car. All for $8k!
