Defending series champion and defending Indy 500 winner Bobby Rahal and his Truesports team made a highly publicized switch from the March chassis to the up-and-coming Lola chassis. Truesports, however, stayed with the proven Cosworth engine. For 1987, the Ilmor Chevrolet Indy V-8 expanded its participation, fielding cars with Penske Racing, &lt;a href="Newman/Haas%20Racing"&gt;Newman/Haas&lt;/a&gt; and Patrick. Mario Andretti scored the engine's first Indy car victory in the season opener at Long Beach. Also joining the series full-time was the Judd AV V-8 (badged initially as the Brabham-Honda), and later in the season Porsche made their Indy car debut. Penske resumed their in-house chassis program, but after dismal results with the PC-16, the cars were parked during practice at Indy in favor of the March 86C.
