Spanish Autoblogger Alberto Ballestín Gil caught these photos of the much-anticipated 2007 Porsche 911 GT3 at the Geneva Motor Show. The basis for Porsche's 911 GT3 RSR racecar puts out 415-horsepower from its 3.6-liter flat-six engine for a specific output of 115.3 horsepower-per-liter, "among the highest of any naturally aspirated production car," according to the automaker. The high-revving beaut also claims improved airflow in the form of a throttle valve enlarged from 76 to 82 millimeters, optimized cylinder heads, and a low-backpressure exhaust.
One thing that may be a slight annoyance to some is that the tachometer signals the optimum time to shift gears -- most Porsche guys we know don't need any help from the instrumentation, though some might find it a welcome addition.

ATLANTA, Feb. 24 — Porsche's new 2007 911 GT3 will make its public debut at the
Geneva Motor Show on February 28, 2006. The latest race- bred 911 sports coupe features a 415-horsepower naturally
aspirated engine with an 8,400 rpm redline, an active suspension setup tuned for the track, and a mechanical
Serving as the homologation basis for Porsche's 911 GT3 RSR racecar, the 911 GT3 provides enthusiasts with an uncompromising road car that can easily transition to weekend track-day outings. The 415-horsepower, 3.6-liter flat- Six engine produces a specific output of 115.3 horsepower-per-liter, among the highest of any naturally aspirated production car. The Boxer engine's power peak is reached at 7,600 rpm, on the way to an 8,400 rpm redline -- 200 rpm beyond the previous GT3 model.
In addition to its high-revving characteristics, the GT3 engine's performance has been fortified by careful attention to airflow rates. Changes to the variable intake system include a throttle valve enlarged from 76 to 82 millimeters, optimized cylinder heads, and a low-backpressure exhaust system.
To take advantage of the extended-rev characteristics of the engine, the 2007 911 GT3 features a revised six-speed manual transmission, with lower gear ratios for 2nd through 6th, as well as shortened shift-lever throws. A new change-up display, which illuminates the tachometer shortly before the relevant engine speed is reached, provides GT3 pilots with an additional signal to optimize shift timing.
The combination of a more powerful, higher-revving engine and shortened gear ratios produces impressive acceleration figures, allowing the 2007 911 GT3 to reach 60 mph from a standstill in 4.1 seconds (0-100 km/h, 4.3 sec.), and 100 mph (160 km/h) from a standing start in 8.7 seconds. The top test- track speed of the new 911 GT3 is 193 mph (310 km/h).
For the first time, the 911 GT3 boasts an active suspension. The standard Porsche Active Suspension Management (PASM) system offers two chassis in one: the default configuration is similar to that of the previous model and is suitable for driving on alternating road surfaces. In Sport mode, the system provides even firmer damping, enabling more focused dynamics for the racetrack.
For the best possible transmission of engine power to the road, the GT3 is equipped with a comprehensive traction package, including new electronic Traction Control adapted from the Carrera(R) GT, standard-equipment 19-inch sports tires, and a mechanical limited-slip differential. The new Traction Control setup features traction-slip and drag-torque control functions, allows the safe application of power under any driving conditions, and can be completely disabled if desired.
The 2007 Porsche 911 GT3 will be available in North America beginning in August 2006. U.S. pricing for the new model is $106,000.
