Re: Jetta Hybrid Conert?

The drive shaft to a rear drive axle will turn about the engine speed in 4th
gear [manual] or Drive [for an automatic]. For most "small" cars this will
be at least 4000 RPM at 60 mph

13 inch tires turn about 950 revolutions per mile, while large [235/75R15]
tires are about 720 revs/mi. The "final drive" ratios are up to 5:1 in a
small engined car, with down to 2:1 for a large V8, without overdrive

I would think the easiest "hybrid" to construct would take a 84-92 Honda
Civic wagon, or a Toyota Tercel, or Corolla wagon. All these were available
as 4WD. [I'm sure there're other similar combinations, Subaru comes to mind
also]

Install the "4wd" rear axle in your 2wd car, it bolts up to the chassis.
Install a small [6.7" ADC for example] motor in the tunnel, and follow it
with a small manual trans, like a pre 76 Volvo. Now depending on how many
batteries, and how you set up the controls, you can go all electric, all IC,
or any combination. Adding 5 electric horsepower, at cruising speed would
REALLY cut fuel consumption.

Obviously this would require "lumps" in the floor/tunnel, but easily
dooable.
