Porsche 911 GT3 RSR gets Bigger Engine, Sleeker Aerodynamics

The fastest Porsche 911, the awesome GT3 RSR, will be cruising into the new model year with a new powerplant and a new cowl.

The most distinctive feature of the ultimate Porsche 911 is the redesigned nose with larger air outlets on the front panel. The modified air ducting coincides with the installation of an optional air-conditioning unit which required a change in the supply and discharge of air; also to cool off the radiators. Underneath the GT3 RSR, more aerodynamic changes were also made. And the rear wing was rigged for a wider range for adjustment depending on how fast the car was driven.

Compared to the previous model, there is a weight-optimised braking system and a lighter wiring harness, for improved handling.

The GT3 RSR’s ‘boxer’ engine has been upgraded from 3.8 to 4.0-litres. Reduced air restrictors for 2009 (as mandated by the world of motor sport’s governing body) enables the powetrain to generate 450 bhp (331kW) at 7800 rpm, and a maximum torque of 430 Nm at 7,250 rpm. The engine now has lower rev levels for any given power output making it more responsive to drive.

Inside the ultimate 911, a new multi-function display above the dashboard indicates the optimum time to shift gears. New features include a programmable multi-function, on-board supply sytem control device, giving racing teams a choice of options—such as an infinitely adjustable blinking frequency function for the lights in the front apron; helping the pit stop recognize its own cars coming in at night-time in long distance endurance events.

The 911 GT3 RSR is one of three successful long distance Porsche racers, each unit costs 380,000 Euro plus VAT specific to each country.
