The Penske PC-27 was a CART racing car designed by John Travis and manufactured by Penske Cars in Poole, Dorset. The design was based around the team's 1997 car, the PC-26. It competed in the 1998 CART season and, as the PC-27B, in part of the 1999 season. In the 30 races that it took part in, its best finish was second at the 1998 Budweiser 500k in Japan. The PC-27 was the last CART racing car built by Penske, before the team switched permanently to customer chassis.
