The SEMA Show, starting 31 October, will see the premiere of the NSX “Dream Project”, ARX-05 Daytona Prototype international (DPi) and the Pikes Peak Acura TLX A-Spec.
The ARX-05 is joined by an exposed carbon fiber-bodied NSX GT3 race car and three podium-finishing Acura race cars fresh from this year’s Pikes Peak International Hill Climb.
Also debuting at SEMA is the “Dream Project” second-generation NSX created by acclaimed NSX specialist, ScienceofSpeed. The modified Nouvelle Blue Pearl 2017 Acura NSX features a GT3-inspired carbon fiber aero kit, lightweight forged wheels, custom two-tone interior and subtle enhancements to the supercar’s powertrain and suspension to further elevate performance of the electrified supercar.
NSX “Dream Project”
The “Dream Project” Acura NSX features optimized engine performance through liquid injection intercooling and free-flowing high-performance downpipes and exhaust, resulting in a combined 610 horsepower (+37) and 507 lb.-ft. torque (+31). A more aggressive stance is achieved with the ScienceofSpeed lowering kit and wider Advan GT forged wheels.
To make approaching difficult driveways and speed bumps easier, ScienceofSpeed integrated automatic sensing suspension technology from iLIFT which uses patented sensors to automatically raise the front axle of the NSX two-inches when obstacles are detected.
The Dream Project NSX features thoughtfully executed exterior and interior styling enhancements including a gloss black roof in homage to the first-generation NSX, a more aggressive GT3 inspired aero kit and custom interior highlighted by Recaro racing seats.
Acura ARX-05 Daytona Prototype
The ARX-05 marks the Acura brand’s return to prototype racing along with legendary partner Team Penske, which will campaign two Prototypes in the IMSA WeatherTech SportsCar Championship next year. The Acura ARX-05 will make its competition debut in the Rolex 24 at Daytona in January 2018 with drivers Juan Pablo Montoya, Helio Castoneves, Graham Rahal, Dane Cameron, Ricky Taylor and Simon Pagenaud.
The Acura ARX-05 [Acura Racing eXperimental, generation 5] is the latest in a successful line of endurance prototypes fielded by the brand beginning more than 25 years ago (1991). The prototype race car 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.
The AR35TT has powered class winners at the 12 Hours of Sebring, the 24 Hours of Le Mans, and a LMP2 World Endurance Championship in 2012. The engine also powered entries to American Le Mans Series LMP2 titles in 2012 and 2013; and the overall winners at the Rolex 24, 12 Hours of Sebring and Petit Le Mans in 2016.
Acura NSX GT3
The race-winning Acura NSX GT3 just wrapped its inaugural racing season with two teams racing in the IMSA WeatherTech SportsCar Championship series and the Pirelli World Challenge series, finishing with four podiums and three victories.
Now offered for sale globally, the NSX GT3 features a multi-material body structure and TIG-welded chrome-moly roll cage, built alongside the production NSX at the Performance Manufacturing Center (PMC) in Marysville, Ohio.
The production-based 3.5-liter, twin-turbocharged V-6 racing engine uses the same design specifications as the production NSX, including the block, heads, valve train, crankshaft, pistons and dry-sump lubrication system and is assembled alongside the production engine at the Anna Engine Plant (AEP) in Anna, Ohio. Final assembly of the race car is completed at JAS Motorsport in Italy.
Pikes Peak Acura TLX A-Spec
The Pikes Peak-prepared Acura TLX A-Spec marked its racing debut in 2017, winning the top spot in the Exhibition Class with a time of 11:03.655 at the legendary hill climb. Pikes Peak veteran and engineer in charge of the NSX’s dynamic performance development, Nick Robinson, piloted the car.
A team of R&D engineers led by Robinson optimized the Pikes Peak Acura TLX A-Spec specifically for the hill climb through custom engine software and powertrain components pulled from the TLX GT race program, including rods, pistons, camshafts and valvetrain. The team turbocharged the 3.5-liter V-6 up to 500-horsepower and added a limited-slip differential for more effective transfer of power to the front wheels. Modified race suspension, brake components, and aggressive aero enhancements including a hand-crafted carbon-fiber splitter and standoff rear wing further enhance the TLX A-Spec’s race abilities.
In its first run to the 14,115-foot summit, the TLX GT, driven by long-time Acura race car driver, Peter Cunningham, set a new Open Class record this year, with a time of 9:33.797, finishing second overall and earning Cunningham “Rookie of the Year” honors for the annual event.
The all-wheel drive TLX GT race car features the same twin-turbo V-6 motor used in the Pirelli World Challenge series from 2014 to 2016, specifically tuned for the challenging elevation changes of Pikes Peak. Other modifications to the Acura TLX GT included aerodynamic components such as the addition of front fender louvres and more aggressive dive planes. Downforce was also increased by moving the rear wing up and back.
Pikes Peak GT3-inspired Acura NSX
The 2017 Acura NSX earned a podium finish in 10:03.433, taking third place in the highly competitive Time Attack 1 class. Behind the wheel was James Robinson of the company’s North American R&D powertrain development group. A veteran of Pikes Peak, James has competed every year since 2011, driving a first-generation NSX in the Pikes Peak Hill Climb from 2012 to 2015 and winning the Exhibition class in 2011.
Taking learnings from past runs, as well as adapting ideas from the successful NSX GT3 race car, the Pikes Peak NSX received weight reduction and additional aerodynamic elements, including a larger rear wing and front splitter. Software tuning for the engine the Sport Hybrid system and R-compound tires further optimized performance for the challenging hill climb.
