The Phil Knox fleet - 34 years of aeromodding
I talked to Phil on Saturday - I was hoping to meet up with him in Texas this weekend, but unfortunately my trip was cancelled, so it'll have to be another time.

I didn't realize until I read the piece featuring several ecomodders from this forum that he's been doing this stuff for so long!

Anyway, we talked about a bunch of stuff, including many of his vehicles, and I thought it would be interesting to present his "aero fleet" in a single thread. So, with Phil's blessing, here it is:

The first one he aeromodded was his...

'64 VW Karmann Ghia
  • bought to replace a thirsty El Camino with a v8 that could get 18 mpg at best
  • the Ghia was purchased wrecked - the previous owner had smacked into the back of a big Caddy, braking on a wet road.
  • Phil put the front clip from another Ghia on it, and then started modding it after reading about Car & Driver magazine's Crisis Fighter Pinto
  • Reshaped the front to mimic a Porsche Carerra
  • was good for 41 mpg @ 70 mph

'62 Dodge D-100 pickup
  • this was his grandad's truck (still has it!)
  • the shape of things to come?

'70 VW bus
  • link to thread with more details of this project:
  • Modding this VW was Phil's thesis project, and he used many of the same techniques NASA did for its van testing:
  • full belly pan
  • skirts on rear wheels
  • 18 inch tapered rear extension

1984 Honda CRX
  • ultimately, the mod set included: nose, hatchwing, gap-fillers,wheel skirts,wheelcovers,bellypan,and boattail
  • 18% improvement in mpg, 36% drag reduction, 9mph improvement in top speed
  • Estimated Cd: 0.23
  • tested at Bonneville, and systematically at Chrysler Proving Grounds, in Michigan in 1991.
  • Still has it! (On guard duty - long story)

'94 Toyota T-100
  • what *hasn't* Phil tried on this famous truck? :)
  • @ 75 miles per hour, with aero mods fuel economy improved to 32 miles per gallon from stock 23.3 mpg.

Custom mini hypercar

  • under construction
  • motorcycle based
  • VW front end?

Thanks for the inspiration and the education!

Love the CRX and the Ghia

I always loved the look of the KG. An e-KG would be a nice project.

Heh, all I could think of is electrocardiogram. An EV conversion on that car could only be called "The EKG Machine" in my eyes. :thumbup:

Hyper car!!! I've wanted to build something like this for 20 years!!!! I might have to now. I always thought it would be best to use a 700cc or larger shaft drive (or belt drive) motorcycle for the rear. But always thought using a Mustang II style front suspension would be better and help to keep a lower profile.

Is that a Goldwing fairing turned upside down on the front of that?
