There's no room for the manual while the 3.8-liter flat six will generate 15hp more than the outgoing GT3.
The 991 Porsche 911 GT3 is coming along nicely, with numerous prototypes spotted on and around the 'Ring and near Porsche's headquarters in Stuttgart. So while we've built up a good idea of what the new car will look like, up until now we've had no idea what to expect under the skin. Autocar is claiming the new GT3 will be powered by the latest evolution of Porsche's normally aspirated 3.8-liter flat six as opposed to the bigger 4.0-liter powerplant used in the GT3 RS 4.0.
If Porsche insiders are to be trusted, power output will be around the 450hp mark, so 15hp more than the outgoing model. This should equate to a 0-62mph time of less than 4.0 seconds and a near 200mph top speed. As for the transmission, it appears Porsche have finally ditched the manual with the only option to be a PDK seven-speed, dual-clutch transmission. Although heavier than the manual, insiders have also claimed 40kg has been shed from its predecessor wiith a curb weight of 1,395kg thanks to an increased use of lighter materials, reduced trim and equipment inside, and the removal of the rear seats.
Prior to the 911 GT3's unveiling at the 2013 Geneva Motor Show next March, Porsche will launch the Carrera 4 and 4S most likely at September's Paris Auto Show. The hardcore GT3 RS will return sometime in 2015 complete with 480hp.
