IndyCar Returns to Phoenix Raceway for Tire and Technical Tests
IndyCar will conduct critical tire and technical specification tests at the one-mile Phoenix Raceway oval on October 26-27, ahead of its March 7 event. This marks a pivotal return for the series to the historic venue, where significant changes have been made since its last appearance in 2018.
Scott Dixon, a two-time Phoenix winner, will drive the No. 9 Chip Ganassi Racing Honda, while Alexander Rossi will utilize the No. 20 Ed Carpenter Racing Chevy during the tests. This session aims to evaluate tire performance and car dynamics on a newly configured track that includes notable modifications, such as the re-numbering of turns and the addition of a ‘Dogleg’ for NASCAR.
IndyCar’s prior race at Phoenix on April 7, 2018, saw Josef Newgarden take victory after starting from pole position. The track has since undergone extensive renovations, including a repaving that altered the banking and grip levels. These changes present unique challenges, particularly with vehicles now incorporating advanced safety technology such as the aeroscreen and hybrid powertrains, making the current DW12 the heaviest IndyCar ever at this venue.
Dixon and Rossi are expected to navigate the track above the newly established yellow line, unlike NASCAR drivers who have the option to utilize the lower line. The anticipated rapid tire degradation due to the track’s surface and banking will be a focal point during the sessions, with plans for shorter runs on Thursday and longer evaluations on Friday. Downforce adjustments will also be tested.
A follow-up test is scheduled for January, where insights gathered will inform final car specifications for the dual NASCAR and IndyCar event in March, ensuring both series are optimally prepared for competition.
