Named in honor of the late Dan Wheldon who conducted its initial development, the Dallara DW12 is the spec chassis utilized by the Verizon IndyCar Series. Dallara was selected to supply chassis to the IndyCar Series by a blue ribbon panel of drivers, designers, promoters and administrators as part of the ICONIC Plan (Innovative, Competitive, Open-wheel, New, Industry-relevant, Cost-effective). In keeping with the ICONIC principles, the DW12 incorporates a host of features designed to enhance both the competition and safety of IndyCar racing including partially-enclosed rear wheels, a bumper/nerf bar and robust nose wing construction, along with a fixed cost of $349,000 per chassis. In addition, the chassis is intended to support multiple aerodynamic kits, the introduction of which is still pending. Currently, Chevrolet and Honda supply 2.2 liter, turbocharged V6 engines for the DW12. The engines produce up to 700 bhp and are equipped with push-to-pass functions on selected road and street courses.
