AC Propulsion Power Sweeps Arizona Electrics

---

March 21, 1999
Chandler, AZ

AC Propulsion electric drive systems finished 1-2 in the Arizona Electrics today at Firebird Raceway near Phoenix, Arizona. In the feature event for Formula Lightning electric racecars, Billy Roe drove the AC Propulsion-powered University of Oklahoma entry to the win after qualifying on the pole and setting fastest lap during the race. AC Propulsion also powered Craig Taylor to second place in the Ohio State car.

The 28-lap feature race around Firebird Raceway's road-racing course requires a combination of driving skill, race strategy, and rugged performance. On race day, Oklahoma had the right combination as Billy Roe pulled out a lead while maximizing distance on the first two battery packs. "On our third pack, we were able to push hard because we had plenty of juice", said team leader, Professor John Fagan, "The AC Propulsion motor was ready to go, we never ran hot and Billy could push hard right to the end."

Oklahoma and Ohio State use the AC-150 drive system which is manufactured by AC Propulsion for use in road-going electric vehicles. With 150 kW (200 horspower) produced from a motor that weighs only 110 pounds, the AC-150 gives racecars the same thing it gives passenger cars: superior performance. Both teams have found that the air-cooled AC-150 requires surprisingly few modifications to adapt to the rigors of competition. Over the years, Oklahoma and Ohio State, the only teams powered by AC Propulsion, have often ended up racing between themselves for the win because the AC-150's high power, light weight, and good durability deliver an unbeatable combination.
