2011 Porsche 911 GT3 RS 4.0 Coupe

Porsche produced 600 examples of the Porsche 911 GT3 RS 4.0 in 2011. It was a track-focused thoroughbred that had the largest engine ever (up to that point) fitted in the rear of a street-legal 911. The engine was sourced from its competition GT3 R and RSR race cars, and as such, many of the high-tech track-specific components also found their way onto the street.

The larger displacement was courtesy of a longer stroke, while titanium connecting rods and a single mass flywheel kept the internals as light as possible. A modified intake manifold with shorter runners, high-flow air filter, and a less restrictive exhaust increased airflow into the engine.

Carbon fiber was used for the construction of the hood, front fenders, and seats, resulting in a curb weight of just 3,020 pounds. The PDK transmission was deemed too heavy, so the 911 was given a manual gearbox. Buyers were also allowed to option out the radio and air conditioning.

In the back was a large rear wing which worked in conjunction with a large front splitter and dive planes to provide high levels of downforce at speed. Dynamic engine mounts, while adding four pounds, firmed during hard cornering in order to keep the rear-mounted engine's mass in check. Michelin Pilot Sport Cup tires, fitted as standard, provide immense grip.

This 997 GT3 RS 4.0 is fitted with both the radio and air conditioning. It has been driven just 690 miles since it left the factory. It is serial number 489 of the 600 produced and one of just 126 examples that were brought to the United States.

The RS 4.0 was available in either black or white. This example is finished in white.
