UNSER SETS RECORD ON HOOSIERS
AT PIKES PEAK INTERNATIONAL HILL CLIMB

7-16-03

The winning combination: Hoosier tires+Unser+CPI Battery TechnologyCOLORADO SPRINGS, CO (July 9) -- While setting records is nothing new to the Hoosier brand, setting them in an electric powered car with a member of the famed Unser family driving is. The record setting performance occurred at the annual Pikes Peak International Hill Climb in beautiful Colorado. The historic 12.42-mile run was a result of the combination of Hoosier race tires, a battery-powered race car, and the skill of driver Jeri Unser, daughter of famous race car driver Bobby Unser. When it was all over, the previous record mark was crushed by over 45 seconds. 

The credit for the record setting run was a collective effort and can be shared by many--not least of which was the car, named the Electric Racecar 3 (ER3). The ER3 is powered by 450 lithium ion battery cells and was jointly developed by LG Chem in Korea and Compact Power Inc in Colorado. 

The ER3 actually smashed its own record set in last year's race. The red, white and blue #92 climbed the Pikes Peak Hill in 14 minutes and 33.12 seconds breaking the old pure-electric record by more than 45 seconds. The race tests the latest battery technology under extreme driving conditions. LG Chem's Battery R&D team, under the guidance of Dr. M.H. Kim also develops low weight, high capacity, and high power batteries for laptop and cell phone applications. Success on Pikes Peak also serves notice that LG Chem is a legitimate competitor in the automotive advanced battery market required by hybrid electric vehicles requiring batteries that last up to 15 years. 

The driver Jeri Unser, daughter of 3-time Indy 500 winner (1968, 1975, 1981) Bobby Unser, masterfully navigated the electric racer up the 156 turns climbing over 4,708 feet in just 12.42 miles en route to the record setting run. 

The tires were selected with the input of Hoosier Road Racing Product Manager Bruce Foss and Randy Ruyle of Ruyle Racing Services who helped prep the car for competition. The two decided upon Hoosier's 20.0 x 6.5 -13 WET (Catalog # 44140) race tires for the front and 22.0 x 9.0-13 WET (Catalog #44217) race tires for the rear. Mr. Foss commented, "While we didn't have anything specifically designed for this application, we felt the aggressive WET tread design and the softer compound would be well suited to the rigors of the Pikes Peak climb and the record setting run speaks for itself."   

The Pikes Peak International Hill Climb is the second oldest car race in the United States going back some 80 years. Hoosier Racing Tire is proud to have played a part in the record-setting run of the ER3 at this year's Pikes Peak International Hill Climb.
