The KI racer was built during the 2007-08-competition year.  Although this vehicle looks like our old XRV electric vehicle, it’s completely different.  The chassis of this vehicle was constructed from 1” mild steel tubing. The students did all the fiberglass work on this vehicle.  It utilized a solid front end with rack and pinion steering, with a rear swing arm suspended using pit bike rear shocks with modified springs.  The vehicle utilized a two-speed jackshaft assembly, custom hydraulic disk brakes and Briggs and Stratton World Formula engine.  This vehicle performed three “hot laps” at Wisconsin International Raceway.  The fastest lap average speed was 45.2 MPH.  It was not quite as fast as our 54-A car due to the difference in chassis weight and gear ratios.
