The official race debut of the 963 was at the2023 24 Hours of Daytona,the season-opening round of the2023 IMSA SportsCar Championship.The car was originally slated for a non-competitive dress rehearsal at the 20228 Hours of Bahrain,[10]however, Porsche decided later that they would not race at Bahrain in favour of more private testing time.[11]Porsche later announced that the first customer 963s would not be delivered until April 2023 due to delays caused by supply chain disruptions, forcing customer teams to miss the opening races of the IMSA SportsCar Championship and WEC, something that the teams understood when engaging in talks with Porsche to take delivery.[12]

Background

edit

Porsche last competed in theFIA World Endurance Championship's top class, LMP1, back in 2017 with thePorsche 919 Hybrid,and in theIMSA SportsCar Championshipwith thePorsche RS Spyderin the LMP2 class, with the 919 taking outright championship victory in its final year of competition, and the RS Spyder taking outright championship victory in theAmerican Le Mans Seriesand class championship victory in theEuropean Le Mans Series.[13][14]Following the withdrawal of Porsche's factory LMP1 and LMP2 teams from the World Endurance Championship and American Le Mans Series, Porsche maintained a presence in the lower classes with continued factory support for the911 RSRin the American Le Mans Series'GT2(later GTLM) class, and in the World Endurance Championship's GTE class.[15][16]TheAutomobile Club de l'Ouest,the organiser of the24 Hours of Le Mans,issued a statement regarding the matter, saying that the club "regrets this precipitous departure, as it does the abruptness of the decision from one of endurance racing’s most successful and lauded manufacturers".[17]

As part of the LMDh regulations, interested parties can choose four constructors to partner with to construct the chassis upon to which design the car, those four constructors beingOreca,Ligier,MultimaticandDallara.[18]Head of Porsche Motorsport Pascal Zurlinden announced in March 2020 that Porsche would be evaluating an entry into LMDh, saying "Porsche is seriously looking into it, but there is no decision yet".[19]This was followed up with an announcement in December that year that development of a LMDh project would commence, meaning Porsche would be the first manufacturer to commit to the LMDh class.[20]

A multi-year partnership withTeam Pensketo run the factory team under the banner of Porsche Penske Motorsport was announced in May 2021. The announcement marked the commencement of third major collaboration with between Porsche and Team Penske, continuing a decades old relationship that began with thePorsche 917/30inCan-Amand blossomed again with thePorsche RS Spyderin LMP2 class of theALMS.The collaboration aimed to debut with two entries each in the top classes of the2023 FIA World Endurance Championshipand2023 IMSA SportsCar Championship.[21]

Vice President of Porsche Motorsport Fritz Enzinger commented that "Porsche and Penske shared a proven track record of success" and that "In the long list of victories to date, however, the name Le Mans has been missing. I hope that we will finally be able to chalk up this success as of 2023 with Porsche Penske Motorsport. This would then mark Porsche's 20th overall victory at the Sarthe - a dream come true."[21]

In the same month,Multimaticwas revealed to be the constructor that would supply the chassis for which Porsche would design bodywork, with Enzinger saying that "Multimatic is the most obvious and logical solution for us", and that "We have known this highly respected company and its team of experienced professionals for many years and are absolutely convinced of the quality of their work".[22]

Testing commenced at the beginning of 2022, with the first tests being at Porsche's test track at Weissach,[23]where the car's engine choice was also revealed, that being atwin-turbochargedV8,which is developed from the engine found in thePorsche 918which in turn was developed from the 3,397 cc (207.3 cu in) V8 found in thePorsche RS Spyder,paired with the standardised hybrid parts provided byWilliams Advanced Engineering,BoschandXtrac.[24][25]This was followed by an extensive testing program at theCircuit de Barcelona-Catalunyaand theCircuit de Spa-Francorchamps,where the car covered over 6,000 km (3,728 mi).[26][27][28]

Porsche also announced in May 2022 that four 963s would be allocated to customers for 2023, at the cost of $2.9 million per car, with full factory support.[29][30]JDC–Miller MotorsportsandJOTA Sportboth announced on the 25th of June that they would take delivery of one car each, with JDC MotorSport campaigning the 963 in theIMSA SportsCar Championshipand JOTA fielding the car in theFIA World Endurance Championship.In November 2022,Proton Competitionwas revealed to have purchased the remaining 2 customer entries, fielding a single entry in each in theWECandIMSAin 2023.[31][32][33]

Racing history

The No. 5 963 at the2023 Sahlen's Six Hours of The Glen

Due to supply-chain constraints,Porsche Penske Motorsport,the factory team, was the only team that could field the 963 at its debut at the2023 24 Hours of Daytona.[34]

The 963 made its first appearance in the practice sessions of the2023 24 Hours of Daytonaalongside the other newGTPcars., theBMW M Hybrid V8,theAcura ARX-06,and theCadillac V-LMDh.The 963 was often right behind the ARX-06s ofMeyer Shank RacingandWayne Taylor Racing,with the former leading all five practice sessions, bar the last one.[35][36]During the race, both Porsches were beset by reliability issues, with significant time spent in the garages: No. 7 was the first to come in, losing 35 laps to replace a faultybattery,[37]and Tandy – in No. 6 – had been running in contention for overall victory in the morning until a gearbox failure ended his race.[38]

The Porsche 963 took its first victory in IMSA competition on theStreets of Long BeachwithMathieu JaminetandNick Tandydriving.[39]In the season's fourth round, theMotul Course de Monterey,Matt Campbelltook the car's first pole position while Tandy's No. 6 started second and van der Helm's No. 5JDC–Miller Motorsportscar qualified ninth.[40]The No. 6 car recovered to second after a slow start. Campbell hit the No. 94Andretti AutosportAston Martin Vantage AMR GT3,losing time as he served a drive-through penalty. A crash at turn 10 after Nasr relieved Campbell relegated the No. 7 car to ninth.Tijmen van der HelmandMike Rockenfellerfinished seventh inJDC–Miller Motorsportsfirst race with the car.[41][42][43]At Watkins Glen, Tandy and Jaminet started from pole position after qualifying was cancelled.[44]Porsche Penske Motorsport's No. 6 car battled for the win. Through a better pit-stop strategy, the No. 6 Porsche overtook the No. 31 Cadillac and the No. 60 Acura and rejoined in second with 40 minutes remaining.[45][46]Jaminet overtookConnor De Phillippiin the final minutes before the race ended behind the safety car.[47]The No. 7 car was in contention until Nasr sustained an issue with the hybrid system and spent 2 hours replacing the battery, gearbox and rear axle.[48]It later emerged onto the track and finished 52nd overall. Later, the No. 6 Porsche was disqualified for illegalskid blockwear.[49]

In 2024, the Porsche 963 took its first major endurance race victory with a win in the24 Hours of Daytona,withPorsche Penske Motorsportwinning with driversDane Cameron,Matt Campbell,Felipe Nasr,andJosef Newgarden.[50]In the2024 Qatar 1812 km,the opening round of the2024 FIA World Endurance Championship,Porsche 963s swept the podium positions, with the Porsche Penske Motorsport cars taking 1st and 3rd and aJOTAentered car taking 2nd.[51]
