The 991-generation 911 RSR was Porsche's works GTE weapon — from 2017 famously mid-engined — winning Le Mans GTE-Pro in 2018 with the 'Pink Pig', plus IMSA and WEC championships, before GTE's end made it the last purpose-built factory racing 911.

## History

The RSR name returned to the 991 platform in 2013 as a rear-engined GTE car, but the 2017 RSR was the revolution: Porsche moved the 4.0-litre naturally aspirated flat-six ahead of the rear axle — effectively mid-engined, a first for a racing 911 — to free diffuser volume and centralize mass. The RSR-19 evolution of 2019 refined cooling, aero and serviceability around the same philosophy.

The results justified the heresy: Le Mans GTE-Pro victory in 2018 for the #92 'Pink Pig' — the retro livery instantly selling out merchandise worldwide — alongside the #91 Rothmans-tribute car's podium; WEC GTE drivers' and manufacturers' titles in the 2018–19 superseason; IMSA GTLM championships (2019); and GTE-Am titles for customer RSRs through the class' 2023 sunset.

With GTE dead and the 992 generation racing only in GT3 form, the 991 RSRs stand as the final factory-built, non-customer racing 911s. Works cars are museum-bound or placed; customer RSR-19s from the GTE-Am years circulate quietly at the top of the collector-racer market, eligible for the growing GTE 'legends' grids that Peter Auto and Le Mans Classic are assembling.

## Palmarès

Le Mans GTE-Pro winner 2018 (#92 Christensen/Estre/Vanthoor 'Pink Pig'); WEC GTE manufacturers' and drivers' champion 2018–19; IMSA GTLM titles 2019; GTE-Am world championships and Le Mans class wins with customer RSR-19s through 2023; Sebring, Petit Le Mans and Spa class victories across both generations.

## What to check before you buy

Sort generation first: 2013–16 rear-engined RSRs, 2017 mid-engined cars, and RSR-19s are three distinct machines sharing a name — parts, values and eligibility differ. Porsche Motorsport chassis files authenticate everything; the 4.0 GTE engines are factory-controlled items whose rebuild status must come documented. Works cars essentially never trade; the market is customer GTE-Am RSR-19s, priced on race history (a Le Mans class win multiplies value), spares packages and Weissach service continuity. Confirm emerging GTE-legends grid eligibility — it is becoming the reason to own one.

## Did you know

- Porsche never called the 2017 RSR 'mid-engined' in press material — engineers preferred 'rear mid-engine'; the paddock just called it the fastest 911 heresy ever built.
- The 2018 Pink Pig livery reprised the 1971 917/20 'Truffle Hunter' — the winning car's merchandise sold out before the race ended.
- With no exhaust behind the axle, the 2017 RSR gained side-exit pipes whose bark made it the loudest GTE car of its era by trackside consensus.
