If the RC and RC F Coupes are any indication, it looks like Lexus will start fitting its high-performance models with a new, single-frame version of the spindle grille while a dual-frame grille will be reserved for lesser trims. Backing up that suspicion is the new single-frame grille found on this prototype, marking the first time the suspected F line styling piece has been seen on a GS F prototype.
The aforementioned staggered quad exhausts look good on the GS' rear end, while a none-too-subtle rear spoiler ups the rear's visual flair. The low-profile rubber and the multi-spoke, black wheels are nice touches that work well with the front fascia features, in addition to the new, camo'd grille and substantial brake cooling ducts.
With such a high degree of finality on this prototype, here's hoping we see the production GS F sooner rather than later.
