Porsche has taken the wraps off the new 911 RSR at the Los Angeles Auto Show.

The full release and all technical details of Porsche’s latest, and perhaps most revolutionary GTE challenger to-date, are below:

Porsche will tackle the 2017 racing season with an all-out newly developed GT racer. The new 911 RSR makes full use of the breadth of the Le Mans 24 Hours GT regulations, and in addition to systematic lightweight design, features the ultra-modern, flat-six engine positioned in front of the rear axle. The extremely light four-liter powerplant is highlighted by direct fuel injection as well as a rigid valve drive and is characterized by outstanding fuel efficiency. The new 911 RSR will make its debut at the 24 Hours of Daytona race in January 2017.

“While retaining the typical 911 design, this is the biggest evolution in the history of our top GT model,” says Head of Porsche Motorsport Dr. Frank-Steffen Walliser.

The new 911 RSR is a completely new development: the suspension, body structure, aerodynamic concept, engine and transmission have all been designed from scratch. The engine concept has enabled the designers to install a larger rear diffuser. Combined with a top-mounted rear wing adopted from Porsche’s LMP1 prototype racecar, the 919 Hybrid, the level of downforce and the aerodynamic efficiency has been significantly improved.

“For the 911 RSR, we deliberately focused on a particularly modern and light normally-aspirated engine, as this gave our engineers immense latitude in developing the vehicle,” explains Dr. Walliser. “Apart from that, in principle, the LM-GTE and GT Le Mans class regulations stipulate the absolute equality of various drive concepts, as the torque characteristics of turbo and normally aspirated engines are aligned.”

The changeover to the new engine generation is now complete. After the 911 GT3 R and the 911 GT3 Cup, the spearhead of Porsche GT racing cars is now also powered by the same cutting-edge six-cylinder boxer engine family. Depending on the size of the restrictor, the new normally aspirated unit develops approximately 510 hp (375 kW). Shift paddles on the steering wheel actuate the sequential six-speed gearbox with a magnesium housing, which delivers power to the 12.2 inch-wide rear wheels.

In the past, Porsche also thoroughly pushed the limits with the concept of the 911, for example, in 1996 with the 911 GT1. In 1998, the 911 GT1 achieved the 16th overall victory for Porsche at the Le Mans 24-hour race. In 2016, Porsche furthered its record by earning an 18th overall class victory with the 919 Hybrid at the most famous of all endurance races.

For the first time, a Porsche GT racecar features state-of-the-art assistance systems. The new 911 RSR is equipped with a radar-supported collision warning system, the popularly-called “Collision Avoidance System”. Even in the dark, the faster prototypes are detected early enough that misunderstandings can be avoided. A new safety cage concept and a new, rigidly mounted racing seat enhance driver safety. With the seat fixed to the chassis, the pedals can now be moved and adjusted to fit the driver.

The new 911 RSR’s serviceability has also been significantly improved. Entire elements of the carbon-fiber body can be completely exchanged in a very short time thanks to clever quick-release fasteners. Moreover, changes to the suspension setup can be performed much more quickly and easily.

With the look of the body wrapping, the 911 RSR is striking out in a new direction. For the first time, the GT racer bears the new factory design that has further developed the clear and dynamic design language of Porsche Motorsport. From a bird’s eye view, a hint of the Porsche emblem silhouette can be seen. The basic colors remain white, red and black.

In the 2017 season, the factory is expected to run the new 911 RSR at 19 outings equating to more than 140 hours of racing. With two factory-entries, Porsche will tackle the FIA World Endurance Championship (WEC) including the 24 Hours of Le Mans as well as the North American IMSA WeatherTech SportsCar Championship. The new racer will celebrate its debut under the toughest conditions at the IMSA season opener in Daytona on January 28-29.

“We’re very well prepared for this,” says Marco Ujhasi, Head of GT Works Sport. “Since its first rollout in Weissach in March this year, we’ve covered more than 21,000 test miles (35,000 kilometers) on racetracks in Europe and North America – that’s more than in the development of any other previous Porsche GT racer.”

Final 2023 Rolex 24 at Daytona results, stats

DAYTONA BEACH, Fla. — The 2023 Rolex 24 at Daytona overall results were all streaks: two consecutive victories in the endurance classic for Meyer Shank Racing and three in a row for Acura.

And Helio Castroneves became the second driver to win three consecutive Rolex 24s and the first to win in three straight years (Peter Gregg won in 1973, ’75 and ’76; the race wasn’t held in ’74 because of a global oil crisis).

Starting from the pole position, Tom Blomqvist took the checkered flag in the No. 60 ARX-06 that led a race-high 365 of 783 laps with co-drivers Castroneves, Simon Pagenaud and Colin Braun.

Meyer Shank Racing now has two Rolex 24 victories and the 2022 championship since entering the premier prototype category of the IMSA WeatherTech SportsCar Championship in 2021.

“I think what’s so special about this team is we are a small team compared to some of our opponents, but the atmosphere, the way we work, enables people to get the best out of themselves, and I think that’s why we’re such high achievers,” Blomqvist said. “I think there’s no egos. It’s a very open book, and that just enables each and every one of us to reach our potential. I think that’s why we’ve achieved so much success in really a short time at this level of competition.”

It’s the 16th IMSA victory for MSR.

The 61st running of the Rolex 24 at Daytona marked the debut of the Grand Touring Prototype category that brought hybrid engine technology to IMSA’s top level.

In other categories:

LMP2: James Allen passed Ben Hanley on the final lap and delivered a victory in the No. 55 ORECA by 0.016 seconds. It’s the second IMSA victory for Proton Competition, which last won at Sebring in 2012. It was the first Rolex 24 victory for Allen and co-drivers Gianmaria Bruni, Fred Poordad and Francesco Pizzi.

GTD Pro: Cooper MacNeil won in the last start of his IMSA career as the No. 79 Mercedes-AMG GT3 scored the first Rolex 24 at Daytona for WeatherTech Racing and the team’s fourth career victory.

MacNeil, who co-drove with Maro Engel, Jules Gounon and Daniel Juncadella, earned his 12th career victory and first at the Rolex 24.

“Winning by last IMSA race is tremendous,” MacNeil said.

GTD: The No. 27 Heart of Racing Team delivered the first Rolex 24 at Daytona for Aston Martin, which has been competing in endurance races at Daytona International Speedway since 1964. Drivers Marco Sorensen, Roman De Angelis, Darren Turner and Ian James (also the team principal) earned the victory in the English brand’s 13th attempt.

It’s also the first Rolex 24 at Daytona win for Heart of Racing, which has seven IMSA wins.

LMP3: Anthony Mantella, Wayne Boyd, Nico Varrone and Thomas Merrill drove the No. 17 AWA Duqueine D08 to victory by 12 laps for the team’s first class win in IMSA.
