Laydown (5051 & 5062) For several years, Chief Mechanic George Salih had worked with the idea of building a roadster with the Offy motor installed horizontally to achieve the lowest possible center of gravity. Accommodating the exhaust header and oiling problems led Salih to lay down the engine 72 degrees from vertical rather than 90 degrees. Quin Epperly fabricated the body for the Salih Roadster, and veteran driver Sam Hanks qualified the radical new car for the 1957 Indianapolis 500. Hanks won the race and announced his retirement from racing in Victory Lane. The same car was driven to victory in 1958 by Jimmy Bryan, a feat achieved by three cars previously but none since. This started a fad for laydown roadsters that lasted until the rear-engine revolution in the mid 1960's Driver A. J. Foyt and Chief Mechanic George Bignotti won the 1960 USAC National Championship with a laydown roadster running a portion of the schedule of races.

Rick Mears won the 2nd of his 4 Indianapolis victories for Penske Racing in 1984. The March Chassis
was a favored choice by several racing teams at Indy during the 1980's, winning from 1983 through 1987.
Penske Racing captured 3 of those wins with Mears, Danny Sullivan (1985) and Al Unser, Sr. (1987).
