Hardcore Porsche 911 GT3 RS Spied Testing Might Have More Than 500 HP


It appears that Porsche is readying an even more hardcore 911 GT3 RS model for this generation.

Spy photographers have caught this mean looking Porsche 911 prototype testing and rumors suggest that it could be a 911 GT3 RS 4.2 model packing more than 500 horsepower. The current Porsche 911 GT3 RS is already sold out and is powered by a 4.0-liter engine, meaning the updated version could have a 4.2-liter mill. Up front, there’s a bold fascia with large air intakes, while the rear has been heavily disguised. There are new exhausts at each side, compared to the setup for the current GT3 RS, which has a dual exhaust exit in the center.

The spy photos also hint that this particular model has extra air intakes in the rear, while the aerodynamic setup looks quite different than what comes with the current GT3 RS. There’s also a rear diffuser that resembles what’s found on the recently unveiled 911R.

The more interesting idea is that with this sort of exhaust setup, it could hint at a Porsche 911 GT2 RS model with a turbocharged engine. Porsche has remained adamant that the GT3 variants will stay naturally aspirated, so the real question is, would a larger 4.2-liter engine really need additional cooling vents? Or is that mainly to help keep a turbocharged engine cool?

    The old GMC Jimmy/ S10 Blazer had a 4.3 Vortec V6
    and those things were excellent at towing.

    4.2 flat-6 (even a high revving oversquare one) can’t be that different
    it’s still a lot of displacement spread out over just six cylinders.
