Earlier this week, we previewed two very special Acuras heading to Monterey Car Week. One was the return of Tony Stark’s one-off NSX Roadster, now set for a 2026 auction. The other was this, the Acura RSX Prototype EV, now making its global debut in California.
The RSX follows Acura’s recent pattern of using Monterey to showcase its EV future. In 2022, the Japanese brand unveiled the Precision EV Concept. Last year, it showed the Electric Vision Design study and the ZDX concept, the latter becoming Acura’s first production EV on GM’s Ultium platform.
Painted in a striking shade of Propulsion Yellow Pearl against a black roof, the RSX Prototype EV is a sharply styled preview of the production version of the RSX arriving in late 2026. This will be Acura’s first model engineered entirely in-house on Honda’s own new global EV platform. Production will begin at the brand’s new EV Hub in Marysville, Ohio, at the end of 2025, on the same line as the Integra. This flexible manufacturing setup will allow Honda to build ICE, hybrid, and EV models together.
Acura says the RSX will mark its entry into the “Software Defined Vehicle” era with ASIMO OS, first shown at CES 2025. This proprietary system integrates automated driving, advanced driver assistance, infotainment, and other vehicle systems, while learning your driving habits and preferences. Over-the-air updates will add features over time.
Performance hardware is confirmed: dual-motor all-wheel drive, sport-tuned double wishbone front suspension, and high-performance Brembo brakes are all standard, with Acura claiming a low center of gravity. However, the company has not yet released specific figures for horsepower, torque, range, or battery capacity, so exact performance numbers remain under wraps. The RSX also works as mobile energy storage, able to power appliances or provide home backup power.
Styling draws heavily from the Acura Performance EV Concept, with a sleek coupe-like fastback roofline, retractable handles, and a ducktail-style spoiler. The separated-headlight design, slimmer DRLs, and functional lower fascia improve aerodynamics and cooling. A full-width taillight pays homage to the second-gen NSX, and the new “ACURA” font is stamped across the tailgate. Flared wheel arches house 21-inch multi-spoke wheels, framing bright red Brembo calipers.
The RSX Prototype debuts at The Quail on Friday, August 15, at 10:36 a.m. PT, followed by an appearance on Pebble Beach’s Concept Lawn on Sunday, August 17.
