Acura has unveiled the Integra Type S HRC Prototype, signaling a thrilling new direction for performance enthusiasts. This prototype hints at a forthcoming line of street and track-focused performance parts from Honda Racing Corporation (HRC), developed by the very engineers behind championship-winning race machines. Making its debut during Monterey Car Week, a premier global gathering for automotive and motorsport aficionados, the Acura Integra Type S HRC Prototype elevates the already impressive Integra Type S to new heights of dynamic capability, promising ultimate performance for both the road and the racetrack. This exciting development allows Acura enthusiasts to tap into exclusive HRC race engineering to enhance their own Integras. As Jon Ikeda, Senior Vice President, Honda Racing Corporation USA, stated, “Every spec of the Acura Integra Type S HRC Prototype screams performance. Everything is functional – if it doesn’t add performance it isn’t on the car.”
Spearheaded by HRC US in Southern California, the Integra Type S HRC Prototype is a comprehensive upgrade, targeting improvements across the entire driving experience. From engine and suspension enhancements to superior braking and significant weight reduction, this prototype showcases the untapped potential of the Integra Type S, pushing its performance boundaries for both street driving and demanding track conditions. The public can witness the Acura Integra Type S HRC Prototype firsthand at The Quail, a Motorsports Gathering, on Friday, August 16.
Aerodynamic Optimization for High-Speed Stability
The aggressive and distinctive styling of the Acura Integra Type S HRC Prototype originates from the Acura Design Studio in Los Angeles. Drawing directly from the aerodynamic expertise gained in developing the Integra Type S TCX racecar, the prototype features a range of functional aerodynamic elements designed to maximize downforce and enhance stability at high speeds. The redesigned front fascia incorporates a larger front splitter and cooling ducts, while larger hood vents and side splitters further refine airflow. A key element is the adjustable carbon fiber rear wing, mounted on aluminum uprights, contributing significantly to optimized aero performance at track velocities.
The prototype’s striking visual presence is amplified by its Indy Yellow Pearl paint finish, a vibrant hue first introduced on the second-generation NSX supercar. Custom milled aluminum HRC badges, proudly displayed on the grille, front fenders, and decklid, make a bold statement, mirroring the iconic logo seen on victorious Honda and Acura race vehicles in prestigious series like IndyCar, IMSA, and Formula 1.
Weight Reduction through Carbon Fiber and Strategic Design
A core principle in enhancing the Acura Integra Type S HRC Prototype’s performance is weight reduction. Extensive use of carbon fiber components plays a crucial role, with the hood and rear door panels crafted from this lightweight material. Inside, aggressively bolstered one-piece Recaro bucket seats replace the standard units, further contributing to weight savings. The rear seat has been ingeniously removed and replaced with a carbon fiber shelf, designed to securely transport four mounted wheels and tires – a practical feature for track-day enthusiasts.
Combined with an optional air conditioning delete, these measures result in a remarkable weight reduction of nearly 200 lbs compared to the standard Integra Type S, directly translating to improved agility and responsiveness.
Enhanced Engine Performance and Precision Handling
The high-revving turbocharged 2.0-liter VTEC® engine of the Acura Integra Type S HRC Prototype benefits from several performance enhancements derived from the Integra Type S HRC TCX race car program. A larger intercooler and twin oil coolers improve cooling efficiency, while a tuned, lightweight cat-back exhaust system optimizes engine output and response.
Handling is significantly sharpened by a track-ready suspension setup lowered by 15mm. This system features tuned coilovers, an adjustable rear anti-roll bar, and adjustable front and rear camber plates – components closely related to those used in the Acura Integra Type S HRC TCX race car. Forged lightweight 19 x 9.5-inch wheels with an increased negative offset widen the front and rear track by 30mm, enhancing both handling and the vehicle’s aggressive stance. These performance wheels are paired with track-focused Pirelli P Zero Trofeo R ultra high-performance tires (265/30ZR19) with a 60 Treadwear rating, maximizing grip and cornering capabilities.
Braking performance is elevated with the introduction of massive 15-inch two-piece front rotors, 1.4 inches larger than the standard Integra, and Brembo® 6-piston aluminum calipers. Two-piece rear rotors further reduce unsprung weight. Larger ducts integrated into the front fascia optimize brake cooling by directing increased airflow to the front rotors, ensuring consistent braking performance under demanding conditions.
Chassis rigidity is reinforced by a robust X-Brace in the rear bulkhead, providing enhanced structural integrity and serving as an attachment point for multipoint harnesses. This brace is finished in the same striking Indy Yellow Pearl paint as the exterior. The performance-focused cabin is further refined with black Alcantara accents and color-matched yellow seatbelts, stitching, and trim, creating a premium and driver-centric environment.
