Porsche 963 Le Mans Racer Gains One-Off Roadcar Version

Porsche may not be in the best of positions now. However, the good news is that the brand now has a thriving endurance racing programme once again that’s arguably on the verge of charting success again, and it still has a knack for building special and limited-run models too.

Lately, the latter two have merged to birth the one-off Porsche 963 RSP pictured. Essentially, this is a 1-of-1 special street-legal roadcar version of the Porsche 963 LMDh Le Mans prototype race machine.

Porsche has built a one-off 963 RSP based off its 963 LMDh Le Mans prototype endurance racer.

Notable too is who now owns this one-off - Roger S. Penske. Yes, the very same founder and owner of Team Penske, knwon as "the Captain" in the motorsports circle.

Equally special too is who it’s built for, with the ‘RSP’ in this one-off’s name being the clearest hint. If you asked us, there’s arguably no one else more fitting to commission and take ownership of this special.

If you haven’t guessed it yet, ‘RSP’ are the actual initials of Roger S. Penske. Renowned as “the Captain” in the racing world, the former racer and founder of both the Penske Corporation and Team Penske is the proud owner of this special.

The Porsche 963 RSP build was reportedly inspired by the one-off road-legal Porsche 917 that the marque built and delivered to Count Gregorio Rossi di Montelera in 1975.

The 1975 Porsche 917 one-off mentioned and the 963 RSP share the same distinct 'Martini' silver paint.

This build was reportedly inspired by, and specified to match, the road-legal version of the legendary Porsche 917 that Porsche famously built and delivered to Italian aristocrat Count Gregorio Rossi di Montelera in 1975 – the very 917 unit pictured above.

This also perhaps explains the distinct ‘Martini’ silver paint that dresses the carbon fibre exterior of the Porsche 963 RSP.

Effectively, the Porsche 963 RSP rekindles the spirit of the road-going Le Mans legend detailed that it built some 50 years ago. Notably, like the one-off 917 mentioned, the 963 RSP is also technically identical to the 963 LMDh racecar mentioned.

For the uninitiated, the Porsche 963 LMDh competes in both the World Endurance Championship (WEC) and the annual Le Mans 24 Hours. The latter is where said racecar is vying for glory once again – rivals Ferrari have dominated in 2023 and 2024.

At the core of the Porsche 963 LMDh  is a chassis based on an LMP2-spec chassis built by Canadian firm Multimatic. Powering it is a 4.6-litre V8 twin-turbo hybrid powertrain derived from the Porsche 918 Spyder hypercar that puts our roughly 671 HP.

Officially, Porsche skirted away from revealing any official performance data. For reference though the Porsche 963 LMDh racer has a claimed 0-100 KM/H sprint time of roughly 3 secs whilst enroute towards a supposed V-max well beyond 330 KM/H.

Despite being 'softened' for road use, much of the original 963 racecar's essences and bits remain.

Also, instead of adapting an ex-racecar unit, the Porsche 963 RSP was built by the Atlanta-based American division of Porsche’s Sonderwunsch bespoke arm. The homologation from racecar to street-legal road car saw plenty of additions and tweaks too.

Key amongst which include head- and taillights plus indicators, suspension set at its highest setting, subtly reworked bodywork, as well as the fitment of less extreme wet-weather tyres – evident by the added grooves in its tread pattern.

Inside, the racecar’s spartan cabin still only seats one, but it’s now covered plush tan leather and what appears to be suede. What’s interesting here too is the addition of a special cupholder and the presence of what appears to be a radio comms headset unit.

Inside, the Porsche 963 RSP continues to be a single-seater, but it has been 'softened' too with plush leather and suede covers. Notable additions include a special cupholder and radio comms headset.

Notably, instead of a conventional turn-key process, the Porsche 963 RSP still requires a laptop to start – perhaps this is not a problem for racing team owner Mr Penske.

Lastly, price officially remains undisclosed, but reputable sources online have reportedly understood that the Porsche 963 RSP build’s costs in the region of US$5 million – or approx. RM21.14 million.

For now, the Porsche 963 RSP remains a one-off for now. However, Porsche has reportedly not ruled out building another, especially if approached by the right kind of customer, galactic-sized bank account not withstanding…
