Porsche’s answer is as simple as it is brutal: It will advance the 911 in perpetuity by making every conceivable metric and component just a hair better, over and again. If you bump everything by just 2 or 3 percent, you might enjoy a 2 or 3 percent improvement in lap times, which Webber will attest is enough to stay ahead of the pack, at least on the track.
In the case of the new 911—known by Porschephiles by its internal 992 designation and initially available as the S model and the all-wheel-drive 4S—that means tweaking key chassis, body, powertrain, and electronics elements. In the rear, the new 3-liter flat-6 engine receives new, more precise fuel injectors, higher compression, and asymmetrical valve strokes that improve fuel efficiency and smooth out performance. Larger, now symmetrical turbochargers respond faster, improving efficiency and power delivery. The improvements push the engine from 420 to 443 horsepower, and torque from 368 to 390 pound-feet.
