His victory at Michigan was his first career win on an oval and he joined Jacques Villeneuve as the only PPG CART World series drivers to win Rookie of the Year honours and the PPG Cup championship in their first two seasons in the series. Zanardi also became the first Italian-born driver to win the PPG Cup championship since Mario Andretti in 1984. He started on the pole at Homestead, Australia, Cleveland and Vancouver establishing a PPG CART World Series record for consecutive pole positions at Homestead and Australia. He also became the eighth driver to win three consecutive PPG CART World Series events with his victories at Michigan, Mid-Ohio and Road America and the seventh to win the championship during that same season.
1996 Registered three victories and a series-leading six poles en route to the Jim Trueman Rookie of the Year award. Driving for Target/Chip Ganassi Racing, he finished third in the PPG Cup points (132), the highest showing by a rookie since Nigel Mansell won the title in 1993. All three of his triumphs came from the pole (Portland, Mid-Ohio and Laguna Seca). Other poles came at Rio, his career first in CART, Road America and Vancouver. He established new track qualifying records at Mid-Ohio, Vancouver and Laguna Seca. He was the most dominant driver in the second half of the season with three victories and three other podium finishes in the final eight races. Led the series in times led (26) and laps led (610). The 610 laps led established a new single-season rookie record, eclipsing the mark of 603 set by Mansell in 1993. The total ranks in a tie for seventh all-time with Mario Andretti (1987). Started on the front row in the final eight races to tie a series record for most consecutive front-row starts held by Bobby Unser (1979-80) and Bobby Rahal (1985).
