A six-speed manual is standard in GT3 models but we've proven the optional seven-speed PDK automatic is quicker, as it shifts quicker than a human and seems to be linked to the driver's cerebral cortex. The GT3 RS comes only with the PDK gearbox. While the GT3 and GT3 Touring models are designed to thrill on the world's most challenging race courses, they're nearly as supple-riding and easy to live with as the regular 911 when driven on city streets. It's this dual-purpose nature that makes the GT3 one of our favorite sports cars and why it easily earns a place on the highest pedestal of automotive icons.
