DEAR  iRACING USER,

Congratulations on your purchase of the Dallara IR-01! From all of us at iRacing, we appreciate your support 
and your commitment to our product. We aim to deliver the ultimate sim racing experience, and we hope 
that you’ll find plenty of excitement with us behind the wheel of your new car!
The Dallara IR-01 is iRacing and Dallara’s answer to the challenges of premier international open-wheel 
motorsport. Designed to blend together the best elements of grand prix racing’s past, present, and future, 
this fast and agile machine is easy to pick up, but limited electronics and driver aids make it challenging to 
master.
The IR-01 is powered by a naturally aspirated, 3.0-liter V10 reminiscent of the engines that dominated 
the sport in the early and mid 1990s. Producing upwards of 900 horsepower at a dry weight of just 600 
kilograms, the result is an aggressive car that races well in traffic and is a pure thrill ride to drive.
The following guide explains how to get the most out of your new car, from how to adjust its settings off of 
the track to what you’ll see inside of the cockpit while driving. We hope that you’ll find it useful in getting up 
to speed.
Thanks again for your purchase, and we’ll see you on the track!
