Roger Penske was always looking for ways to gain the 'Unfair Advantage' with his cars. The Penske PC23 Mercedes, debuted at the 1994 Indy 500, bent the rules very close to the breaking point. Created in absolute secrecy, the new engine from Ilmor gave Team Penske 200 more horsepower than any other car in the race. The race was a turning point in American open wheel racing and for Team Penske, beating big names like Mario Andretti. The innovative redesign included a custom push-rod system and restyled rear deck. Of the eleven victories with this car, five were complete podium sweeps for Team Penske. No car rivaled the Penske PC23 and the engine was later ruled illegal. In a story that reads like a spy novel, the dramatic journey from recognizing the loophole to winning the Indy 500 is recounted in great detail with behind-the-scenes reporting.
