Original lunar tire
design by Ken Rieli 1963
First Non-pneumatic Tire Design

1960's ATV prototype with
hydrostatic drive.

Series hybrid, all-wheel drive vehicle.
Ken did the original concept design of this vehicle.
His Dad designed the drivetrain & sold the ATV concept to LTV.

Concept grew into the MACV -
built by LTV
Aerospace 1967-1968.
Ken's dad, Anthony Rieli, headed up the project.



A later version was produced
for agricultural use in Asia.
The world's first
volume-produced, all-purpose hybrid vehicle.

Ken Rieli was the KID Vehicle Special Projects/Materials
Manager -
LTV Aerospace 1969.
He also put the KID
through its paces as a test driver.

New combustion models, improved
geometry disk turbines, differential hydraulic systems, and novel long travel
suspension systems designs emerged from PNGinc's labs.

These technologies
were united in the Phoenix KE Drive™ design,
which was an improvement on the basic ATV drivetrain.
