The next three Verizon IndyCar Series races are on oval racetracks, but that’s where similarities end.

Rounds 11-13 of the schedule further showcase the series’ diversity – a 2-mile superspeedway, a 1-mile flat track and a .894-mile, variably-banked speedway where 17-second laps are the norm – to challenge drivers and their teams.
