The Dallara DW12 is a racing car developed and produced by Italian manufacturer Dallara for use in the IndyCar Series. It was developed for use in the 2012 IndyCar Series season, replacing the aging Dallara IR5 chassis and would be used for the next six seasons until its successor is introduced in 2018 due to series' philosophy of upgrading its chassis every six years since 2012. The DW12 was introduced after 2011 IZOD IndyCar World Championships. The chassis named after Dan Wheldon, who was killed at Las Vegas Motor Speedway on October 16, 2011.
