2018 Porsche 911 GT3 Hardcore New Porsche Tested on Track
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.
The cumulative case it makes is this: When a driver unloads aggression into its controls, it doesn’t balk. It doesn’t plead for mechanical mercy. From its perspective, driving with purpose differs not at all from driving for pleasure. When much is asked of the GT3, it simply goes faster.
It goes faster and then, like a bitterly defiant teenager, it doubles down, betting that what it can endure exceeds what you can supply. That is a profoundly fantastic thing for a sports car to do.
A big part of the latest GT3’s magic is conjured by its engine, a wicked, ripping salute to all that is right with flat-sixes and natural aspiration.
A new version of the 9A1 4.0-liter six-cylinder from the now dead GT3 RS, it replaces the old GT3’s 3.8-liter mill, and this 9000-rpm stomper is wholly updated and more alive than ever. Compared with the 9A1, the 9A1.5 has a new crankshaft, valvetrain design, lubrication system, and intake manifold, and it revs 200 rpm higher.
Larger main and rod-bearing journals allow for a stiffer crankshaft, which reduces wear on the main bearing closest to the rear of the car. The downside is a crank with different resonance characteristics, which demands a heavier dual-mass flywheel to reduce vibration.
