Sales Spotlight: Porsche 911 Carrera 3.0 RSR IROC

The brainchild of Roger Penske – one of US motorsport’s most influential (and successful) team owners – the International Race of Champions, also known as IROC, was conceived as an off-season competition designed to bring together the world’s best racing drivers.

For the first season, held during the winter of 1973-74, racers from Formula One, IndyCar, NASCAR and Can-Am came together at Riverside Raceway and Daytona for four events and a $175,000 prize pot.

All 12 drivers found themselves at the wheel of bespoke Porsche 911 Carrera RSRs. Built by Weissach specifically for the televised race series, the 15 cars were painted in a variety of TV-friendly lurid colours, from Bright Yellow to Acid Blue.


One of the rarest of all the motorsport Neunelfers, a genuine Porsche 911 Carrera RSR IROC has just come up for sale at Maxted-Page, a specialist known for dealing in some of the most historically important Porsche racing cars.

Chassis no. 911 460 0042, finished in Bright Green, competed in the first three IROC races at Riverside, driven by NASCAR legend, Richard Petty, A.J Foyt and F1 star, Denny Hulme respectively, before it was kept on the sidelines at the Daytona finale.

As aforementioned, the IROC RSRs are truly unique creations. A hybrid of the 2.8 and 3.0-litre RSRs, the 15 cars were built at the end of 1973 using G-Series RSR bumpers and the then-new 3.0-litre 911/74 flat six, however the cars left the factory wearing the iconic ducktail rear spoiler and Fuchs alloys.

After the inaugural IROC series had ended, Penske sold the 15 cars to private race drivers and teams with chassis 0042 finding its way to Don Wester and Werner Schoch (both from California) during 1974.

Interestingly, in 1997, appeared for sale with Dr George Konradsheim – author of the definitive 2.7 Carrera RS guide book – who sold the car (then in Austria) back to the USA, where it resided until passing to the UK, via Australia, in 2013.

Sold that year for the first time by Maxted-Page, the esteemed specialist now has the car back in stock and looking for a new home. Understandably, it is listed POA. For more information on the genuine IROC RSR, check out their website now.
