Acura has previewed a new concept ahead of its world debut at The Quail on August 14, using a brief teaser to introduce a design language that the company says will reach production with the fourth-generation RDX Hybrid for MY28. The concept remains unnamed, and the teaser reveals only part of the rear, but its lighting treatment provides the clearest indication yet of the styling direction Acura is preparing for future models.
The 10-second teaser does not show the front, profile, or complete rear of the vehicle. Instead, it focuses on an illuminated Acura wordmark stretching across the tail panel and a pair of split, X-shaped taillights. Each side carries one half of the X motif, with the shapes appearing to point inward toward the glowing brand name in the center. Acura says the concept showcases its new design language.
The X-shaped lighting theme is not entirely new to Acura's recent concept work. A similar motif appeared on a Hybrid SUV concept shown alongside a fastback Honda sedan. In the source, that Acura concept was believed to preview the next RDX, while the Honda was believed to preview a new Accord. The latest Monterey teaser therefore reinforces the visual link between Acura's recent design studies and the next generation of its compact luxury SUV.
Two additional vertical lighting elements are visible above and below the illuminated Acura lettering. The upper strip is described in the source as almost certainly the high-mounted brake light. The function of the lower element is less certain: it could form part of the taillight assembly, operate as a foglight, or serve primarily as an additional nighttime lighting signature.
Acura says the new styling language will first appear on a production vehicle with the fourth-generation RDX Hybrid when that model debuts for MY28. The current RDX, which debuted in 2018, is offered with front- or all-wheel drive and uses a 2.0-liter turbocharged powertrain. The source notes that the present model does not offer a hybrid powertrain and says Acura plans to add one with the next generation.
The report expects the Monterey concept to be a close preview of the next RDX rather than a purely speculative design exercise, although that remains an interpretation rather than a confirmed Acura statement. It draws a comparison with the RSX Concept shown at The Quail in 2025, which the source says would have translated closely into a production RSX before Acura cancelled that program in the spring.
Acura will reveal the unnamed concept in full at The Quail during Monterey Car Week on August 14. Until then, the teaser confirms the rear-lighting theme, the illuminated Acura lettering, and the connection to a broader design language that is intended to move into production. The next concrete step is the concept's public debut, which should show how much of the vehicle's overall shape and detailing points toward the future RDX Hybrid.
