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).

INDYCAR announces several rules and protocol changes for 2018 season

The 2018 Verizon IndyCar Series opener is still more than six weeks away (March 11, St. Petersburg, Florida).

But several rules and protocol changes that will impact much of the 17-race season were announced today by INDYCAR officials.

First is related to Indianapolis 500 qualifying on May 19-20, one week prior to the 102nd running of the Greatest Spectacle in Racing:

* Driver and entrant points will be awarded to the top nine qualifiers for the race. The pole winner earns nine points and the second-fastest qualifier eight points, with awarded points decreasing by one point for each position down to one point earned by the ninth-fastest qualifier.

* Race points for the Indianapolis 500 and the 2018 season-ending Grand Prix of Sonoma on Sept. 16, will still pay double the normal points for driver and entrant.

There are several other changes on tap for the season, as well.

Here’s a quick rundown of those changes (information courtesy of INDYCAR):

  • The qualifying order for all oval track events except the Indianapolis 500 will be determined by entrant points entering the event. The qualifying order will run in reverse order of entrant points, with the highest in entrant points qualifying last. A car without entrant points will be placed at the front of the qualifying line. If more than one car has no entrant points entering an event, a blind draw among those cars will determine their qualifying order at the front of the line. The qualifying order for the Indianapolis 500 will still be determined by a blind draw.
  • Times have been set for the series-wide open test at ISM Raceway (formerly Phoenix Raceway), scheduled for Feb. 9-10. The track will be open to all cars from 3-6 p.m. and 8-11 p.m. ET both days. INDYCAR has also added four hours of track time on Feb. 8 (3-7 p.m. ET) for rookie drivers to complete their oval test assessments.
  • The series-wide open test at Portland International Raceway will be held Aug. 30, a day prior to the beginning of the Grand Prix of Portland race weekend. Indy car racing returns to the Pacific Northwest for the first time in 11 years in 2018.
  • A schedule change for the month of May will see the INDYCAR garages closed on May 13 – the day after the INDYCAR Grand Prix on the Indianapolis Motor Speedway road course – to allow teams time off for Mother’s Day. The track will not be open to the public on this day. The garages will be open on May 14, but there will be no on-track activity.
  • Practice for the 2018 Indianapolis 500 begins Tuesday, May 15 on the IMS oval, with the first two hours open for rookie orientation and veteran refreshers, then to all cars. Practice continues May 16-18, ahead of qualifications weekend May 19-20.
  • INDYCAR is granting teams that did not participate in fall manufacturer testing with the universal aero kit an additional half day of private testing. The testing is limited to one car per team and must take place in conjunction with the team’s first on-track test of 2018. Each team is permitted five hours of track time and two sets of Firestone tires.
  • Working with Firestone, INDYCAR has increased the tire allotment at five events. The race weekends at ISM Raceway (Phoenix), the Raceway at Belle Isle Park in Detroit, Texas Motor Speedway, the streets of Toronto and Iowa Speedway will see teams receive an additional set of tires. In a related change, drivers outside the top 10 in the point standings will no longer have an extra set of tires available to them for the opening practice session of a race weekend.
  • The minimum car weight for 2018 has been increased by 10 pounds – to 1,620 pounds for road and street courses and short ovals, 1,590 pounds for superspeedways (both do not include fuel, drink bottle and its contents, driver and driver equivalency weight) – to accommodate for new parts and additional on-car cameras related to the universal aero kit all competitors will run in 2018.
