The car was originally scheduled to debut this summer, but its arrival may be pushed back slightly because of Porsche’s 911 GT3 engine fire dilemma. Although a fix has been found, Porsche will likely be conducting further tests on the upcoming 911 GT3 RS variant to ensure its engine is as close to bulletproof as possible.
These are the latest spy shots of a prototype for the new GT3 RS, taken while it was conducting some high-speed tests on Germany’s Nürburgring. Spied largely undisguised, the new GT3 RS looks sinister in its all-back exterior, its aggressive aerodynamics and large fixed rear wing making it clear this 911's about business first--and that business happens at the track.
Visual differences from the standard GT3 include a slightly widened track to accommodate wider wheels and tires, a larger lip around the front spoiler, modified rear fender and bumper air extraction paths, and, of course, the much larger rear wing. The side intakes show Porsche is using the extra-wide body of its latest 911 Turbo for the new GT3 RS. It’s not clear if these will remain on the production version.
Expectations for the new GT3 RS include weight reduction, extra power and responsiveness, and an even more focused chassis tune. The current GT3 weighs just 3,152 pounds--relatively svelte for a modern car of its footprint and capability--so the GT3 RS is likely to be at or just under the 3,100-pound mark if Porsche's engineers can shave more weight through use of more carbon fiber panels, a synthetic rear window, and a somewhat more spartan cabin.
