The true genius of Porsche’s new GT3, the second coming of the model on the 991 platform, is that even a master will never fully exploit it. That’s the trait that defines the GT3, not just among Porsches but among the world’s best drivers’ cars. As a result, it engenders fascination like almost nothing else. No matter how hard it’s pushed, there’s still magic to be discovered in its responses, beauty in its feedback, joy in its abilities. This is a machine whetted on the mill of necessity and unencumbered by frippery. It is noise and feel and heat and speed wrapped into a physically absurd package then distilled beyond what its design merits.
