The RS Spyder (known internally as Type 9R6) is a racing car designed by Porsche to compete in Le Mans Prototype Class 2 (LMP2) racing.[2] The car takes its name from the legendary 550 Spyder of the 1950s (combined with Porsche's common "Renn Sport" designation). The car marked Porsche's first return to the top level of sports prototype racing since the firm abandoned its Porsche 911 GT1 Le Mans prototype in 1999.

The RS Spyder made its debut in the final event of the 2005 American Le Mans Series (ALMS) at Laguna Seca winning its class. Since then the RS Spyder has won the ALMS LMP2 Championship in 2006, 2007 and 2008 and took class honours at Le Mans in 2008 and 2009. The outright victory at the 2008 12 Hours of Sebring was the first major victory for Porsche in endurance racing for five years and it was also the first time in 24 years that the non-premier class won the 12 Hours of Sebring overall.

Design

The RS Spyder was designed completely in-house by Porsche engineers. The chassis is a rigid carbon fibre monocoque with both the engine and transmission being integral stressed members. The 3.4 litre 90-degree V8 racing engine was designed from scratch as was the six-speed electro-pneumatic sequential gearbox. Braking is via six-piston caliper carbon-fibre brake mounted on suspension controlled by four-way, spring/damper units activated by pushrods with adjustable torsion-bar springs. The car has a dry weight of 825 kilograms (1,819 lb)in 2010 specification but was initially 750 kilograms (1,650 lb).

Since its introduction in 2005 the engine, which initially produced 478 horsepower (356 kW) has been developed and modified to meet the changing regulations of both the ALMS and the ACO. For 2008 the engine developed 503 horsepower (375 kW) using direct fuel injection and 440 horsepower (330 kW) in 2009-spec with air restrictor limitations.[2]

Race results

2005

The RS Spyder made its race debut at the final round of the 2005 American Le Mans Series, the Monterey Sports Car Championship at Mazda Raceway Laguna Seca, entered by Penske Racing and driven by Lucas Luhr and Sascha Maassen from the Porsche Junioren factory team. The sole RS Spyder finished first in class and fifth overall.[3]

2006

During 2006, Penske entered two RS Spyders in the ALMS and won seven class victories including outright victory at the Mid-Ohio race.[4] This was the first LMP2 victory in a race since 2003 and the first major result for Porsche since the 1998 24 Hours of Le Mans. The results ensure victory for Penske in the LMP2 Championship and also for Sascha Maassen in the drivers standings.[5]

2007

For 2007, Porsche unveiled the 2007-spec RS Spyder (known as the RS Spyder Evo), which included an increase in power to 503 horsepower (375 kW). Dyson Racing joined Penske in the ALMS. 2007 would be the most successful year for the RS Spyder with Penske repeating their outright victory in the ALMS series a further eight times and also securing an additional three class victories. Penske again won the LMP2 class in ALMS and Romain Dumas won the LMP2 Drivers Championship. During the season the RS Spyder won eight races while the Audi R10 TDI from the largest P1 class won only four.[6] Penske had also took 11 class victories from 12 races.

2008

Facing competition from the multiple Acura teams, Porsche made improvements to the RS Spyder for the 2008 season, mainly in the area of aerodynamics. Larger front diveplanes are now used to claw back on downforce deficits to the Acura. Direct Injection was introduced at Long Beach. Rule changes increased the RS Spyder's weight to 825kg. A Penske car driven by Timo Bernhard, Romain Dumas, and Emmanuel Collard, secured the overall victory at the 2008 12 Hours of Sebring, winning it on the 20th anniversary of Porsche's last overall win at the race.[7] Penske had another outright victory at the Utah Grand Prix and also recorded an additional three class wins. At Petit Le Mans a 3rd RS Spyder was entered by Penske in an attempt to lock out the manufacturers championship against Acura. Penske won both the LMP2 Team and drivers championship for Timo Bernhard and Romain Dumas. Porsche won the manufacturers championship by 1 point ahead of Acura.[8]

Danish Team Essex together with Van Merksteijn Motorsport of The Netherlands and Horag Racing of Switzerland participate in the Le Mans Series (LMS) all with 2008-spec RS Spyder. Team Essex and Van Merksteijn also entered the 24 Hours of Le Mans, marking the debut for the RS Spyder at the event. A RS Spyder from Van Merksteijn Motorsport driven by Jeroen Bleekemolen, Peter van Merksteijn and Jos Verstappen, came first in class and 10th overall with the Essex team coming second in class (12th overall).[9] A RS Spyder won its class in every LMS race giving it a 1-2-3 in the LMP2 standing and also securing the drivers championship for Jos Verstappen.

2009

New restrictor rules brought the RS Spyder's power down to 440 bhp, and the wingspan was limited by the rules, effectively decreasing downforce.

Penske did not compete in the ALMS in 2009 but Team CytoSport, who had previously competed in LMP1 in 2007, purchased an ex-Dyson Racing RS Spyder[10] and took part in four races with a best result of second in class at Road America.[11]

In LMS, Team Essex only competed in the 1000 km race at Spa taking the class victory and also at Le Mans again securing the class victory and finishing 10th overall with Casper Elgaard, Kristian Poulsen and Emmanuel Collard at the wheel.Team Goh also took part in the race with an ex-Van Merksteijn Motorsport car[12] and was running a strong second in class when it crashed with less than an hour of the race remaining.[13]

2010

CytoSport announced in February 2010 that it would contest the full ALMS in a RS Spyder.[14] It was also announced that Sascha Maassen would join the regular drivers Klaus Graf and Greg Pickett at the longer races at Sebring, Laguna Seca and Road Atlanta.[15] Cytosport used a full-width rear wing for the entire season, unlike arch-rivals Highcroft HPD. The CytoSport RS Spyder won the LMP2 class at the 12 Hours of Sebring[16] and took their first outright victory at Northeast Grand Prix at Lime Rock.[17] CytoSport continued their winning success by taking outright victory at a shorten race at Mosport.[18] They also finished the season second behind Patrón Highcroft Racing in the championship and Klaus Graf finished second in the drivers standings.[19]

No RS Spyders were entered in the 2010 24 Hours of Le Mans. The new 2011 LMP regulations are likely to render the RS Spyder obsolete, as the current car does not have a fin above the engine cover nor an integrated hybrid system, and the costs exceeds the LMP2 budget limit.
