After a teaser video was released a couple weeks ago, the formal, full unveil of Acura’s new ARX-05 prototype for the IMSA WeatherTech SportsCar Championship, to be fielded by Team Penske, took place today at The Quail, A Motorsports Gathering, in Monterey.

A photo from a private, VIP event emerged on social media on Thursday night ahead of the proper unveil, but now the car is officially out in the open for all to see.

A striking nose assembly section to the ARX-05, on top of the base Oreca 07 chassis, is perhaps the most notable visual identifier on the car.

The full release and a handful of photos are below.

Acura today unveiled the new Acura ARX-05 prototype race car at The Quail, A Motorsports Gathering. Acura Motorsports will join forces with the legendary Team Penske organization to field a pair of the new Daytona Prototype International (DPi) entries in the 2018 IMSA WeatherTech SportsCar Championship.  

The Acura ARX-05 (Acura Racing eXperimental, generation 5) is the latest in a line of endurance prototypes to be fielded by the brand dating to 1991, just five years after the 1986 launch of the Acura marque. Based on the very successful ORECA 07 chassis, the new ARX-05 prototype showcases Acura-specific bodywork and design features, including Acura’s signature Jewel Eye™ headlights, and utilizes the race-proven AR35TT twin-turbocharged engine, based on the production 3.5-liter V-6 that powers the Acura MDX, RDX, TLX and RLX models.

“At Acura, Precision Crafted Performance is at the heart of everything we do.” said Jon Ikeda, Acura vice-president and general manager. “Whether it is our production cars or a prototype race car, if you want to be a performance brand you need to perform.”

The multi-year DPi program will be administered by Honda Performance Development (HPD), the racing arm for both Acura Motorsports and Honda Racing in North America. The competition debut of the Team Penske Acura prototypes will take place at the season-opening Rolex 24 in January, 2018. One of the team’s two ARX-05 entries will be piloted by the legendary Juan Pablo Montoya along with sports car champion Dane Cameron. The second driver pairing will be announced at a later date.

“Right from the start, Acura has raced – and done so successfully,” said Art St. Cyr, President of HPD and Acura Motorsports. “We’ve won with the Acura Integra Type R, the RSX, the first-generation NSX and with the Le Mans prototypes. Most recently, we’ve won with the new Acura NSX GT3. The ARX-05 is our fifth-generation prototype, and we expect great things from our partnership with Team Penske.”

DPi rules require manufacturers to use one of four approved prototype chassis, fitted with IMSA-homologated, manufacturer-designed and branded bodywork and engines. In the case of the ARX-05, the bodywork was developed by a team led by Acura Global Creative Director Dave Marek.

“We created a variety of initial sketches, then pared those down a handful of potential designs. Next came aero and wind tunnel model testing, and time for the engineers to have their say,” Marek recounted. “The design continued to be refined throughout the testing and evaluation process, until we came up with a final treatment that met our performance goals while maintaining Acura styling cues. It’s been an exciting process.”

The Acura ARX-05 will add to a rich legacy of Acura sports car racing successes, including the 1991-93 IMSA Camel Lights manufacturer and driver championships; 50 IMSA and American Le Mans Series class or overall race victories (through Watkins Glen 2017); and the 2009 American Le Mans Series manufacturer, driver and team championships, in both the LMP1 and LMP2 classes.

Based on the “J35” family of engines found in Acura MDX, RDX, TLX and RLX production vehicles, the Acura AR35TT engine has powered class winners at the 12 Hours of Sebring (2011-13); the 24 Hours of Le Mans and LMP2 World Endurance Championship (2012).  The engine also powered entries to American Le Mans Series LMP2 titles in 2012-13; and the overall winners at the Rolex 24, 12 Hours of Sebring and Petit Le Mans in 2016.

Acura Motorsports currently campaigns the Acura NSX GT3 in the IMSA GTD category with Michael Shank Racing – where it has already won at Detroit and Watkins Glen this season – as well as with Real Time Racing in the Pirelli World Challenge GT division.

Following today’s official unveiling, the Acura ARX-05 will also be on display at the Rolex Monterey Motorsports Reunion (August 19) and on the Concept Lawn at the Pebble Beach Concours d’Elegance (August 20).

Mazda Motorsports partners with Team Joest from 2018

A rather stunning, surprise announcement has occurred on Tuesday morning with Mazda Motorsports confirming a new partnership with Team Joest, the longtime successful prototype entrant that was available following the end of Audi Sport’s LMP1 program at 2016.

Joest replaces SpeedSource as Mazda’s factory entrant for its IMSA WeatherTech SportsCar Championship program, starting next year.

This follows reports of Joest’s exploring an entry earlier this year, with Ralf Juttner among others on site in Daytona for the Rolex 24 at Daytona.

The full release is below.

Mazda Motorsports begins a new era today with the creation of Mazda Team Joest, which will be the factory Mazda Prototype race team competing in the North American IMSA WeatherTech SportsCar Championship under Daytona Prototype international (DPi) rules. The team will make its racing debut at the 2018 Rolex 24 at Daytona in January.

Joest Racing is one of the most successful endurance sports car teams in history, with 16 victories at the 24 Hours of Le Mans plus multiple wins in prestigious North American races such as the Rolex 24 at Daytona, ten wins at the 12 Hours of Sebring and six titles at Petit Le Mans. Joest found much of its success as the factory team for Audi from 1999 until the manufacturer ended the program after the 2016 season. Prior to that, Joest Racing had multiple Le Mans victories with Porsche, and was the factory team for Opel in DTM, the German touring car series. The German company was created in 1978 by then-factory Porsche driver Reinhold Joest.

Mazda’s racing heritage includes being the only Asian manufacturer to win overall at Le Mans, plus 22 class victories at the Rolex 24 at Daytona, 13 class wins at the 12 Hours of Sebring and 11 major season championships. According to IMSA statistics, Mazda is the third-most successful manufacturer in the history of North American professional sports car racing, powering 155 major-series victories.

“Since Mazda first took to the race track in 1964, our ‘Never Stop Challenging’ spirit means that every time we race, we strive for victories and championships,” said Masahiro Moro, president and CEO of Mazda North American Operations (MNAO) and managing executive officer, Mazda Motor Corporation (MMC). “The creation of Mazda Team Joest provides us a unique opportunity to partner with a team with proven success in the prototype ranks, and gives us the best chance to return Mazda to the top step of the podium. I welcome the Joest family to the Mazda family, and I’m convinced that, together, we will write many more pages in the book of Mazda racing successes.”

“We are excited and proud about this new opportunity with Mazda,” said Ralf Jüttner, managing director of Joest Racing. “Mazda has such a long tradition in motorsport and, especially in America, has created a huge platform for racing enthusiasts. For us, this is not only a return to American racing, which we have always enjoyed, but also great news to the big group of our Japanese fans, who have always warmly embraced us.”

John Doonan, director of motorsports for Mazda North American Operations, recognizes the new pairing as a “once in a lifetime opportunity.”

“This is an important moment in Mazda Motorsports history as we align our brand’s top-level sports car racing program with one of the best sports car teams of all time,” said Doonan. “What Mr. Joest, Ralf Jüttner and the entire Joest Racing organization have accomplished is not likely to ever be matched. We are very excited to work with them to put Mazda in victory lane and to strive for more championship trophies, adding to the substantial Mazda and Joest Racing legacies in the years ahead.”

With the full focus turning to 2018, Mazda’s current Prototype team will not compete in the three remaining IMSA races this season.

“I want to thank our long-time partners at SpeedSource Race Engineering and owner, Sylvain Tremblay,” said Doonan. “We accomplished a great deal with their organization at all levels of the sport for more than two decades. They are a perfect example of a team that has grown through our Mazda system: from grassroots club racing, to Rolex 24 race-winning efforts in GT and then on to the Prototype program. Friendships in our sport run deep and we certainly don’t see that changing.”

Mazda Team Joest will soon begin testing the Mazda RT24-P in preparation for next season. The production-inspired bodywork treatment developed in concert with Mazda designers will remain, as will the turbocharged four-cylinder, 2.0-liter inline Mazda MZ-2.0T engine which produces approximately 600 horsepower, developed by Advanced Engine Research (AER).

Multimatic Motorsports, of Markham, Ontario, Canada, which was heavily involved in the creation of the Mazda RT24-P, has taken the lead to refine and improve the chassis, and will work closely with Joest in testing and simulation work. The four current Mazda Prototype drivers will participate in the testing and development, but the 2018 driver lineup is yet to be determined.

Joest Racing, based in Wald-Michelbach, Germany, will establish a North American headquarters for the race team in the Atlanta area.

Penske vs. Acura now shifts to Penske with Acura for IMSA return

The halcyon years of the American Le Mans Series, from 2006 through 2008, saw Team Penske’s last major factory effort with the Porsche RS Spyder in the LMP2 class debut the 2005 season finale and the full 2006 season, then witness Acura ramp up its efforts for a 2007 debut with the first iteration of the ARX chassis, the ARX-01a LMP2 car.

Much has changed since. The economic crisis of 2008 had a major impact into 2009 and by that year, the Penske and Acura factory efforts were out, and the ALMS needed to create a spec, lower cost prototype class called Prototype Challenge to keep its car count afloat.

A merger happened in 2014, bringing together ALMS and the GRAND-AM Rolex Series into the IMSA WeatherTech SportsCar Championship (then called the TUDOR United SportsCar Championship), and the late 2015 reveal of the new Daytona Prototype international (DPi) format promised a new rebirth for the top flight of prototype racing in North America.

That period has seen Cadillac, Mazda and Nissan debut DPi programs this year and with Acura’s fully fledged return in 2018 with Penske, it brings together the two past rivals in a united goal for overall glory, and an attempt to topple the existing manufacturers.

“Back then really the interest we had as Penske in getting involved wasn’t so much the P2 class, but it was Porsche was working towards a customer program at the time,” Team Penske president Tim Cindric told reporters on a Tuesday teleconference.

“What we were interested was competing towards overall wins… and we could compete against Audi for those overall wins. And that was before Acura got in. Once Acura got in, that raised the bar – before that, we just were P2 versus Zytek cars, in a privateer setting.

“We were fortunate to race against the Audis and I think that made it fun to try to understand when the underdog could compete. Once Acura got in, it was super competitive, with that second year. Unfortunately that type of racing, that class (at the time) fell apart.

“For us, we see three other manufacturers in. The DPis do allow the privateers to compete with P2 in WEC-type form. There’s a lot of competition. I’m really surprised that only one manufacturer (Cadillac) has won, but that will change as others catch up. For us, it’s not a slam dunk we’ll be winning races right in the beginning.”

Honda Performance Development Art St. Cyr backed up that assessment.

“That’s a great thing about working with Team Penske – there’s a uniform sense of purpose to win overall races,” he said.

“In P2, we had a P2 car that won overall victories. But in P2 we were about winning P2… then moving to P1 was everything we had, with the Muscle Milk Pickett days. It was about how could get stay in front.”

HPD’s recent decade of top flight sports car racing sees the new ARX-05, set to be developed in-house at HPD and based off the successful Oreca 07 chassis, comes after a period of four prior models that raced from 2007 through 2015.

The previous generation ARX-01 had a five-year life span from 2007 to 2011 with various iterations primarily in LMP2 spec and then a one-off LMP1 spec at the 2011 Mobil 1 Twelve Hours of Sebring – where ironically, it finished second to an Oreca-run privateer Peugeot 908 HDi FAP. The HPD ARX-03 achieved success in both LMP1 and LMP2 specifications, primarily with Muscle Milk Pickett in ALMS as mentioned and also with Tequila Patron ESM, Level 5 Motorsports and Starworks Motorsport (won the LMP2 title in the first FIA World Endurance Championship season of 2012), but the ARX-04b, a new LMP2 car developed by Wirth Research for the 2015 season, raced only once at that year’s Rolex 24 at Daytona before being tossed aside following significant weight and teething issues.

With the news officially released that the program is happening will come a summer and fall of preparation before the DPi car’s race debut at the 2018 Rolex 24 at Daytona. Details were sparse today, but here’s the bullet points from today’s call:

  • No drivers have yet been signed, nor was a timeline given for their reveal. But if we’re thinking logically, the Verizon IndyCar Series season ends in mid-September, and Roger Penske said at the Iowa weekend he decides on (or reveals) his lineup once a season is over. We’ll know by then whether Helio Castroneves has won his elusive first championship or not, and Juan Pablo Montoya’s excited Instagram post with the combined Penske and Acura logos today was as good of a confirmation of his expected role. Between current Acura sports car drivers and talented sports car veterans who may be available, there’s a lot of intrigue to come here.
  • Full testing begins next month. Cindric confirmed the first shakedown at Paul Ricard at the end of the month before the car is shipped Stateside, ahead of its Monterey reveal in mid-August. Cindric said the car he hopes will be on track by the end of August. St. Cyr also said the engine will be slightly different than its previous prototype run.
  • What does this mean for other Acura/HPD programs? St. Cyr wouldn’t entirely bite there but did tease there will be “some announcements in the near future.” Full factory support/branding from Acura to its pair of NSX GT3 teams, Michael Shank Racing and RealTime Racing, is expected to be drawn down at year’s end. He also said it was premature to talk about customer programs for the Acura DPi.
  • How does Penske balance Acura/HPD (sports cars), Chevrolet (IndyCar) and Ford (NASCAR)? Like always. “For us it’s old hat,” said Cindric, who described all the internal safeguards that are set up to preserve IP and keep a clear separation of church and state.
  • Does Petit Le Mans happen with a separate car? Possibly, maybe, potentially. Cindric wouldn’t rule out the potential of running a standard LMP2 spec car at this year’s Petit Le Mans but only if the preparation and testing goes well enough with the DPi. “We wouldn’t rule it out, but we’re a long way from confirming it or saying it would happen.”

Overall though today’s announcement brings to an end the saga over how long the return has been in the pipeline and concludes the waiting for the official news to drop.

“During this iteration of the Acura Motorsports programs, it’s been a three-step revival,” St. Cyr said. “It started with the TLX GT car, the NSX GT3 this year and now the DPi program we’re announcing today.

“It started really when the DPi formula was released, we started talking about this vehicle and making it part of Acura’s precision crafted message to align everything… and to have Acura Motorsports be the capital P of performance. Roger Penske being one of our largest Acura dealers created the synergy.”

Cindric added, “On behalf of Roger and everyone at Team Penske, we appreciate the confidence Acura and HPD have in our organization. Sports car racing is where our heritage began. We enjoy competing in it. We haven’t been since 2009.

“When the DPi formula was announced it looked to revive the prototype racing formula in the U.S. It was a natural fit to find the manufacturers in the future. We were interested from day one… now it’s happened. It’s a good format for us. It’ll be competitive and a good challenge for us.”

After months of speculation and anticipation, Team Penske’s return to top flight sports car racing has been made official on Tuesday.

The Penske and Acura Daytona Prototype international (DPi) program will premiere in the IMSA WeatherTech SportsCar Championship with a two-car effort.

The full release is below.

Acura Motorsports today announced it will join forces with Team Penske to field a prototype effort in the 2018 IMSA WeatherTech SportsCar Championship.  The program will include a pair of new Acura ARX-05 Daytona Prototype International (DPi) entries, fielded under the legendary Team Penske banner.

The official competition debut will take place at the season-opening Rolex 24 in January, 2018.  Testing of the Acura DPi will begin soon, with a formal unveiling of the ARX-05 slated for Monterey Car Week in August.  The driver lineup will be announced at a future date.

“Roger Penske is already an important part of the Acura family as one of our great Acura dealers, and now it is a thrill to have him as part of the Acura Motorsports family as well,” said Jon Ikeda, Acura senior vice president and general manager.  “We look forward to building on the success of the race-winning NSX GT3 program, and couldn’t be more thrilled to return to the prototype category of the WeatherTech SportsCar Championship with a partner like Team Penske.”

“We are excited to join forces with the Honda Performance Development family and represent the Acura brand with two prototypes starting in 2018,” said Team Penske Founder Roger Penske.  “Sports car racing has been an integral part of Team Penske’s heritage, from our first race at the 24 Hours of Daytona in 1966 to running the American Le Mans Series in the late 2000s.  Reviving a Team Penske sports car program has always been a goal for us, but to do so required strong and successful partners like Honda and Acura. It’s great to extend our relationship from the dealership to the race track and we are excited to come back to IMSA and the WeatherTech SportsCar Championship.”

The Acura ARX-05 [Acura Racing eXperimental, generation 5] is the latest in a line of endurance prototypes to be fielded by the company dating back to 1991, just five years after the 1986 launch of the Acura brand.  Based on the very successful ORECA 07 chassis, the new ARX-05 prototype features Acura-specific bodywork and utilizes the race-proven, production-based Acura AR35TT twin-turbocharged 3.5-liter V6 engine.

The multi-year program will be administered by Honda Performance Development, the racing arm for both Acura Motorsports and Honda Racing in North America.

“We had a very spirited competition with Team Penske during our previous ALMS Acura prototype programs, and we are looking forward to working with, instead of against, Team Penske as the ideal partner for our return to the prototype ranks,” said Art St. Cyr, HPD president.  “We also had a great deal of success together in CART and IndyCar competition, and Team Penske’s overall record in all forms of racing is unrivaled in our sport.”

The Acura ARX-05 will add to a rich legacy of Acura sports car racing campaigns and championships, including the 1991-93 IMSA Camel Lights manufacturer and driver championships; 50 IMSA and American Le Mans Series class or overall race victories [through Watkins Glen 2017]; and the 2009 American Le Mans Series manufacturer, driver and team championships in both the LMP1 and LMP2 classes.

Acura Motorsports currently campaigns the Acura NSX GT3 in the IMSA GTD category with Michael Shank Racing – where it has already won IMSA GTD races at Detroit and Watkins Glen this season – as well as with Real Time Racing in the Pirelli World Challenge GT division.

One of the most recognizable names in motorsports, Team Penske has scored victories in nearly every series in which the team has competed. With more than 460 major race wins and 29 national championships, including 14 in INDYCAR and 10 in sports car competition, Team Penske is among the most successful teams in the history of professional sports.

More than 30 years after first winning at the highest levels of sports car racing, Team Penske returned to its roots with a successful LMP2-class effort in the American Le Mans Series from 2005-08, winning class championships between 2006 and 2008.

HPD was affiliated with Team Penske in Championship Auto Racing Teams Competition (CART) in 2000 and 2001.  The partnership resulted in 10 race wins, two drivers’ championships (both for Gil de Ferran), and the 2001 CART Manufacturers’ Championship.

More recently, during the single-supplier era in IndyCar Series competition, Penske and HPD combined for two Indianapolis 500 victories (Sam Hornish Jr. in 2006 and Helio Castroneves in 2009), plus the drivers’ title for Hornish in 2006.

Born out of founder Hugues de Chaunac’s passion for racing, ORECA began life in 1972 and has visited Victory Circle in a variety of motorsports disciplines, ranging from prototype endurance events to open-wheel to touring car and rallycross competition.  Teams using ORECA chassis have won more than 350 races, to go with more than 40 national and international titles.

Based on the “J35” family of engines found in Acura RDX, MDX, RLX and TLX production vehicles, the Acura AR35TT engine to be used in the ARX-05 was initially adapted for racing in a joint effort between HPD and Honda R&D Americas.  Used in a variety of prototype chassis, the engine has powered class winners at the 12 Hours of Sebring (2011-13); the 24 Hours of Le Mans and LMP2 World Endurance Championship (2012); the American Le Mans Series LMP2 titles (2012-13); and the overall winners at the Rolex 24, 12 Hours of Sebring and Petit Le Mans in 2016.

Mazda is the first manufacturer to formally reveal its Daytona Prototype international (DPi) platform for 2017, having done so today at the Los Angeles Auto Show.

The full details are below:

The new Mazda RT24-P race car was unveiled today at the Los Angeles Auto Show, ushering a new era in the prominent history of Mazda Motorsports’ flagship endeavors in North America. The new car will compete under Daytona Prototype international (DPi) rules in the Prototype class, the top level of the IMSA WeatherTech SportsCar Championship. After significant on-track testing, it will make its racing debut at the 2017 Rolex 24 at Daytona in late January.

KODO Design

Mazda is known globally for the engineering and design excellence of its vehicles, and the new Prototype is no exception. The bodywork of the race car was developed by Mazda designers utilizing the KODO—Soul of Motion design philosophy. KODO represents the instant that energy becomes motion, such as the muscular beauty as an animal pounces or a human leaps into action. The KODO design cues on the Mazda RT24-P include the sleek body contours and the five-point Mazda grille.

“KODO design is at the heart of any vehicle that carries a Mazda badge, and that is very evident in the design of the 2017 Prototype,” said Ken Saward, senior manager of Design at Mazda Design Americas, which falls under the Mazda North American Operations umbrella. “We considered the two main parameters of designing a successful race car for this series:aerodynamic performance and the new-for-2017 technical regulations. Working with Multimatic’s aerodynamicist and engineers, we discovered that applying the KODO design philosophy to the surfaces and the silhouette of the car enabled us to create a dynamic, purposeful-looking design and a very aerodynamically efficient one.”

Managing the two-car Mazda Prototype factory race team is Florida-based SpeedSource Race Engineering. The team will race the new Riley Mk. 30 chassis, developed by Riley Technologies in relationship with Multimatic. Riley Technologies is a prominent chassis design and development company with 99 race wins and nine Prototype season championships in North American endurance racing since 2004. Canadian-based Multimatic has worked with Mazda since 2014 in the Prototype category, and has developed and built some of the world’s premier on-road supercars and successful sports cars for the race track. The Mazda team will be the first to test the Riley Mk. 30 chassis later this month.

The Mazda RT24-P will be powered by the Mazda MZ-2.0T engine which raced during the 2016 IMSA season. The approximately 600-horsepower engine, developed and raced with Advanced Engine Research (AER), is a 2.0-liter, inline four-cylinder turbocharged engine.

“This is a huge moment for Mazda Motorsports and the entire Mazda family,” said John Doonan, director of Mazda Motorsports North America. “To have a car which features Mazda design language at the top level of our motorsports program is meaningful for us as a brand. We believe we have the right team, the right drivers and the right chassis to win races and championships.

“Mazda has good, long-standing relationships with Riley and Multimatic, and is happy to be the first to test their new chassis. We look forward to seeing it make its racing debut at Daytona with Mazda bodywork and the Mazda MZ-2.0T engine. The strategic vision of IMSA to give auto manufacturers this opportunity to integrate our branding —to better engage our passionate fans— is unique and we’re proud to be the first to unveil what is possible.”

What’s in a Name?

The Mazda RT24-P name echoes the Mazda Road to 24, a driver development program that provides scholarships to help championship-winning drivers progress from grassroots into the upper categories of professional sports car racing. The “24” also represents the two-liter, four-cylinder race engine. The “P” signifies Prototype.

Mazda currently holds a more-than-55-percent market share in grassroots racing, and the Mazda Road to 24 helps provide championship-winning drivers an opportunity to earn scholarships to compete in pro categories such as the Battery Tender Global Mazda MX-5 Cup presented by BF Goodrich Tires. Mazda’s similar scholarship system in open-wheel racing is known as the Mazda Road to Indy. By the start of the 2017 season, Mazda will have provided $14.9 million in driver development scholarships to 53 drivers since 2007.
