HPD ARX-01e LMP1 Sportscar

Wirth Research was requested to produce a new LMP1 prototype for HPD in less than four months, and enter its first race without any pre-event testing. The resulting ARX-01e epitomises the digital, fast response engineering that Wirth Research can deliver. The car ran faultlessly at the Sebring 12-hour race, finishing in second place to a factory supported LMP1 opposition.


Honda Performance Development (HPD) is the centre for American Honda’s high performance racing engine development.


This project had a tight schedule, with a limited budget and high expectations. HPD approached Wirth Research with a challenging request: to produce a new Le Mans Prototype to enter the premier LMP1 class in the Sebring 12-hour race, in less than four months. The client’s budget was limited, with a deadline of just 20 weeks for design, FEA analysis, composite design, procurement and production. Car build time before the race was only 18 days.


The Sebring 12-hour race is one of the world’s toughest endurance races. The Wirth Research designed car ran faultlessly for the duration, finishing second overall against the factory supported LMP1 opposition. Without any pre-event testing, the result was a tribute to Wirth Research’s digital fast response engineering.
