The DW12 IR18 was introduced in 2018 as a replacement for the previous DW12 chassis, and is designed specifically for road courses and street circuits. It features a lower center of gravity, improved aerodynamics, and a more efficient cooling system compared to its predecessor.

The car also includes the Advanced Frontal Protection (AFP) device, a small titanium piece mounted in front of the cockpit that helps to deflect debris away from the driver’s head.
Overall, the Dallara DW12 IR18 is a state-of-the-art race car designed for maximum performance and safety on road courses and street circuits. Its advanced engineering and design make it one of the fastest and most competitive cars in the IndyCar Series.
