With a schedule that includes road courses and ovals of all shapes and sizes, the INDYCAR Series emphasizes the ability of drivers and teams to adapt to a vast array of different circumstances from sweeping, banked, baby’s-bottom-smooth 220 mph turns to corrugated hairpins that rattle your molars at 35 mph. Fortunately, those drivers and teams have the infinitely adaptable Dallara IR18 at their disposal. With 700 horsepower on tap and a wide selection of downforce options, short oval, speedway and road course chassis setups—with us picking the right one for you for each race so you can focus on the driving—the Dallara is just the car to handle the multi-faceted challenges of this series.
