HPD ARX-01c LMP2 Sports Prototype at iRacing.com

No Comment 55 Views

First the car won its class at the Le Mans 24-hour race in June, 2010; then less than four months later the HPD ARX-01c LMP2 capped a championship-winning campaign in the Honda HPD at iRacingAmerican Le Mans Series by Highcroft Racing with victory in the Petit Le Mans race at Road Atlanta.  Now the HPD ARX-01c is headed for glory at iRacing.com, where members of the world’s premier racing simulation and driving game will soon be able to experience for themselves the mind-boggling performance of this amazing racing car.

The production of the virtual version of the ARX-01c is a cooperative effort of HPD, Highcroft Racing and iRacing.com.  Following this weekend’s season-opening American Le Mans Series Mobil 1 Twelve Hours at Sebring, a team of iRacing.com engineers and technicians will join Highcroft for a special test session to gather performance and acoustic data. 

From the start the ARX-01c was a product of design in the digital domain.  It is therefore fitting that this record-breaking car should carry on in the virtual world of iRacing.com. HPD provided key technical information about the car to iRacing.com and at the company’s Bedford, MA headquarters construction of the virtual car’s chassis has already begun.

“Our members are going to be really impressed with the performance of the ARX-01c,” said Steve Myers, iRacing.com’s executive producer.  “When rumors about the car started showing up in our member forum, people got really excited.  We are bringing a lot of resources to bear on this project and plan to have the car ready by late summer, in time for our members to race it in our World Tour of iRacing Petit Le Mans tribute event at the end of September.  Given the ARX-01c’s performance, particularly cornering and braking, people are going to want plenty of time to practice before they start racing this car.”

Myers also noted that the car will also incorporate a new tire model – three years in the works – that will give the ARX-01c even more accurate and realistic performance in the simulation.

The HPD ARX-01c LMP2 will be the second Honda-powered vehicle to join iRacing.com’s fleet (currently 26 cars).  The Dallara IndyCar features a normally-aspirated V8 Honda engine.  iRacing.com’s members drive the Dallara-Honda in several regularly-scheduled series, including the IndyCar Series – Road, IndyCar Series – Oval, and the iRacing.com IZOD INDYCAR Premier Series.
