Expect Porsche to officially reveal the cars during the first quarter of 2020, with examples arriving in customer hands late next year.
Porsche has not confirmed final power figures, but its engineers reworked the Turbos' 3.8-liter flat-six engine with new turbochargers, Piezoeletric direct-fuel injectors (as found on the new, also-turbocharged Carreras), and revised intercoolers. Expect peak horsepower to jump from 580 in the last Turbo S to around 640 ponies, with torque increasing from 553 lb-ft to 580. Porsche estimates the new S will officially knock 0.2-second off the previous car's already stout zero-60-mph time, meaning that figure lands at 2.6 seconds. However, knowing the company's proclivity for issuing conservative performance estimates, we won't be surprised to see the new S make the run to 60 mph in the neighborhood of 2.4 seconds—if not slightly quicker. Likewise, expect the top speed to rise from 205 mph to a 991 GT2 RS-equaling 211 mph.
The updated engine is connected to an eight-speed, dual-clutch gearbox similar to the unit found in the Panamera and 911 Carreras, but uprated to handle more torque and using different gear ratios. It is 53 pounds heavier than the old Turbo S transmission, but it's also shorter in length, allowing it to fit better within the chassis. Additionally, the new car will come to the U.S. market with a particulate exhaust system, now mandatory in Europe. The new hardware adds 20 pounds; overall, the Turbo S should weigh about 3,637 pounds, or 110 pounds more than the old model.
The first car we hopped aboard was a coupe that boasted the Sport Performance package, another first-time offering which lowers the Turbo S's ride height by 20 mm (0.8 inch), and includes additional helper springs and recalibrated dampers. We detected no issues with ride comfort, as the setup was taught, well controlled, and more than acceptable for daily driving. The electronic-damper tuning within the Porsche Active Suspension Management system does a superb job of taking the shock out of road imperfections.
In fact, we felt very little difference between cars with and without the Sport Performance option; the main differentiator was a small increase in suspension compliance, which we expect will yield an ever-so-slightly slower response to steering inputs. Both versions demonstrated excellent roll control, with no chassis yaw or pitch issues, as the all-wheel drive dug deep for every ounce of grip. If the 992 Carrera S is anything to go by, steering feel and front-end controllability should improve over the previous model. We like the Michelin PS4S tires for their all-around wet/dry performance. Also like the Carrera S, the Turbo S employs staggered wheel sizes (20-inch front, 21-inch rear), and the rubber is now 10 mm(0.4-inch) wider all around, measuring 255/35 in front and 315/30 in back.
With so much velocity on-tap, Porsche stepped up the size of the front brake rotors to 420 mm (16.5 inches!), an increase of 10 mm (0.4 inch), while retaining the 390 mm (15.3 inch) discs in back. The 10-piston front calipers are new on the 911 Turbo S; this caliper setup is also found on the latest Porsche Panamera E-Hybrid Turbo S and Taycan Turbo S EV—vehicles that carry more than 1,300 pounds of additional mass compared to this 911. In this application, we expect to find the brakes have the capacity to turn the poor car inside out.
