Penske's 1994 IndyCar World Series Championship was one of, if not the most dominating performance from a race team in history of American open wheel racing. Roger Penske had found the key to win but also found a way to run from the competition. The new Penske PC-23 chassis with the Ilmor- Indy V8 engine would power the Penske drivers of Al Unser, Jr., Paul Tracy, and Emerson Fittipaldi. The team racked up 12 wins out of 16 races, collecting 10 poles and 28 podium finishes on their way to the championship. The team also dominated a controversial May at Indianapolis. Penske debuted a radical new Mercedes-Benz engine at Indy, the 500I. This engine used a provision in the rules intended for stock block pushrod engines such as the V-6 Buick engines that allowed an extra 650 cm³ and 10 inches (4.9 psi/33.8 kPa) of boost. This extra power (at least 900 horsepower, and rumored to be in excess of 1000) allowed the Penskes to run significantly faster, giving them the pole and outside front row on the grid for the 78th Indianapolis 500. Al Unser, Jr. and Emerson Fittipaldi dominated the race, eventually lapping the field with 16 laps to go in the 200 lap race when Fittipaldi made contact with the wall coming out of Turn 4, giving Al Unser, Jr. the lead and win. The only driver who finished on the lead lap was rookie Jacques Villeneuve. This one season gave Penske the Driver's Championship with Al Unser, Jr., Constructor's Cup with the Penske PC-23, and Manufacturer's Cup with the Ilmor-Indy V8 engine. (In the 1995 Indy 500 Penske failed to qualify any cars for the race)
