The original 1 liter concept had a cd of .159 with a 7.5 hp 300cc 1cyl N/A diesel and it managed 235 mpg. They have now changed it (for the worse) the cd is now .195 (the same as the EV1) it has a 2cyl 800cc TDI (half of a 1.6L TDI) that puts out 7 hp in eco mode and 25 hp in "Sport" mode and is a hybrid which added 201lbs to the car and it still manages 170 mpg. (Can I have the original please.)

Very good point. That could be another option for this thread where I said EV1 + 1st Gen Honda Insight drivetrain :

Looks pretty tiny to me.





I have the feeling that the guy with the insight is shorter than the guy with the EV1.

No, the two are very similar, IMO:

Insight:
Length  	3945 mm (155 1/8")
Height (excluding antenna) 	1355 mm (53 1/3")
Width     1695 mm (66 3/4")
Frontal Area:  20ft^2
CdA:  5.00ft^2

EV1:
Length  	169.7 in.  	4,309 mm
Width 	69.5 in. 	1,766 mm
Height 	50.5 in. 	1,281 mm
Frontal Area:  21ft^2
CdA:  3.96ft^2

Neil, did you use the dimensions on the drawing I clipped from YouTube to establish the scale for the EV1? They appear to be correct, except that track width's label is one tire too wide. Track is correctly measured from wheel center to wheel center.

Thanks. A beautiful car indeed. Way ahead of its time aero wise. The Insight 1 is nice but not to the same standard - and I own one. Tragic that GM had no foresight.

I do have one technical question for you aero experts. In profile, the rear window looks too steep to maintain attached flow. Must be 20-25 degrees. How did they get away with that angle?

Hi Jim,

You are referring to the rear window of the EV-1? This has been the subject of other threads here at EM.

The dimentions of the EV1 don't seem right to me, grantid its been 5-6 years but the EV1 I saw on campus wasn't much higher than my belt line, Im 6'4" and it couldn't have been more than 5' wide.

Maybe a height of 42" and a width of 60"

My pickup is supposed to be 66.5" wide, the EV was definetly narrower.

Its very unfortunate that GM was unwilling to make the EV-1 body style into a steel body gasser or hybred drive, its basic shape could easily be transposed into a 3 or 4 seater just by extending the car a tad and aero would remain the same.

Imagine a metro platform with an EV-1 body, sadly KISS wore off on GM with the blasted volt mess.

I have a feeling GM underestimated the EV-1s body style appeal, I still think it is neater looking than a prius and have a feeling many others would have agreed given the opportunity.

Also remember folks, both Dodge & Ford has EV-1 like hybrids designed for the US governments paid requirement as well, both of those body styles would be worth locating for comparison.

Don't forget they both got over 75mpg with the EV-1 around 90mpg as hybrid.

Too bad big auto wouldn't produce them.

The EV1 would probably make a popular fibreglass kit.

An aero kit was the goal of the "Sunrise EV2" project: see http://ecomodder.com/forum/showthrea...again-151.html

Hi Orangeboy,

That first picture is of Phil Karn with his EV-1. I have met Phil, and that picture was taken about 3 years later. I am 5'10" my head only comes up to about his nose - back then.

BTW, that EV-1 of Phil's is the one they gave the Smithsonian...
