In 1994 Della Penna signed Richie Hearn to drive in Toyota Atlantic with the hopes of moving up to CART by 1997. Hearn finished second in points that season and won the championship the following season. Della Penna joined the upstart Indy Racing League in 1996 with the goal of transitioning into CART the following year. In five races between 1996 and 1997, Hearn placed 3rd at the Indianapolis 500, scored a pole position at New Hampshire, and won at Las Vegas. That same year Della Penna ran three races during the 1996 CART season using the same equipment as during the 1996 IRL season.
