The 2006 Porsche GT3 3.6-litre - unveiled at Geneva
The car will be unveiled at Geneva on Tuesday, will go on sale across Europe in May 2006, and in South Africa from August 2006.
The GT3 name is well known for uncompromising dynamics, and this model impresses not only in normal day-to-day driving but also on the race track.
The 305-kW 3.6-litre flat-twin six-cylinder engine produces a specific output of 84.7 kW/litre, top whack for a normally-aspirated motor, and it reaches its nominal output at 7 600 r/min.
At 8 400 r/min the engine speed limit is 200 revolutions higher than for the previous model, which makes it a world leader in its engine-size class.
In addition to this high engine speed it has a variable intake system with a throttle valve enlarged from 76 to 82 mm, optimised cylinder heads, and an exhaust system with low back pressure.
The revised six-speed transmission has very short gear lever travel and, thanks to the lower ratios of gears 2 to 6, ideally complements the racy engine.
New for the GT3 is a change-up display, which lights up on the rev counter shortly before the relevant engine speed is reached.
The GT3 accelerates from 0 to 100 km/h in 4.3 seconds, and reaches 160 km/h from a standing start in 8.7 seconds. Its top speed is 310 km/h.
The new 911 GT3 boasts an active chassis for the first time. Porsche Active Suspension Management (PASM) offers two sporty chassis in one: the basic configuration is largely similar to that of the previous model and is suitable for driving on alternating road surfaces.
In sport mode, the system switches to harder damping, thereby enabling even better dynamism on the racetrack.
The GT3 is equipped with a comprehensive traction package which includes not only the standard-equipment 19-inch sports tyres but also a mechanical limited slip differential.
In addition, the new electronic traction control - adapted from the Carrera GT high-performance sports car - ensures safe traction under any driving conditions.
It features traction-slip and drag-torque control functions, and can be switched off completely if required.
Pricing will be announced when the car is launched here in August
