Luxury car maker, Porsche has revealed that its 2020 911 Carrera S is getting a new body, a heavily revised engine and other technologies.
Motortrend.com quotes the head of Research and Development of the company, Michael Steiner, as saying that the core philosophy behind the design and development of the eighth-generation Porsche 911 was simple.
“We ignored short-lived trends and focused on things we could improve. The new 911 code-named 992 and launching initially in the popular Carrera S and all-wheel-drive Carrera 4S specifications, is longer, wider, and more powerful than the car it replaces. But, more important, it has a new body, heavily revised engine, new transmission, new interior, and sophisticated new driver-assistance technologies,” he says.
He says there are lots of improvements in the new model, beginning with the new body wrapped entirely in aluminium panels.
He adds that the 992’s structure is just 30 per cent steel, down from 63 per cent in the 991, yet rigidity has been improved by five per cent.
“The front fenders are 1.8 inches wider to accommodate a wider front track and provide room for the forthcoming 911 hybrid’s battery cooling system. The wide rear fenders previously reserved for the Carrera 4S are now standard on the rear-drive Carrera S. The new Carrera is 0.8-inch longer overall, the increase all at the front of the car to help meet pedestrian protection regulations. Wheelbase is unchanged from the 991 at 96.5 inches,” he explains.
In its review, Motortrends says aerodynamic upgrades include a flip-up rear spoiler with a 45 per cent larger aerodynamically effective area, continuously variable flaps in the cooling vents at the front of the car that close between 40 mph and 90 mph to reduce drag and fuel consumption, and door handles that cinch down flush with the bodywork.
Its adds, “The 992 Carrera’s twin-turbo flat-six, code-named 9A2 Evo, is still slung out behind the rear wheels, of course, but is now connected to the frame rails by short, stiff mounts bolted to the cylinder heads rather than by a crossbeam bolted to the crankcase as in previous 911s. The benefits include a reduction in throttle-induced engine motions that subtly alter the handling balance.
“The 9A2 Evo shares its crankcase, cylinder heads, oil system, and valve train with the turbocharged engine that debuted in the 991.2. Compression ratio has been upped from 10.0:1 to 10.2:1, more responsive piezo fuel injectors fitted, and the variable valve control system now allows one intake valve to be opened farther than the other under partial load conditions to reduce emissions and improve smoothness.
“The 9A2’s turbochargers are larger, with 1.9-inch turbine and 2.2-inch compressor wheels, bespoke housings for the left and right side units that ensure equal-length intakes, and electronically controlled wastegates. The intercoolers have been moved from behind the rear wheels to under the intake vent on the engine cover to improve cooling air flow.”
Porsche says the 2020 Carrera S is 0.4 seconds quicker than the outgoing model to 60 mph, with an acceleration time of 3.5 seconds, and that the quarter mile is dispatched in 11.9 seconds.
The Carrera 4S’ all-wheel-drive system, which now includes an upgraded front axle with 10 per cent higher torque capacity and water-cooling for improved durability, is 0.1 second quicker than the two-wheel-drive car in both tests, according to Porsche.
“The launch control function of the optional Sport Chrono package shaves 0.2 second from all those times,” the automaker says.
“To capitalise on the more planted chassis, the 992 is fitted with recalibrated EPS, which is quicker and more responsive, coupled with a smaller 14.2-inch steering wheel. The spring rates have been increased by 15 per cent at the front and 14 per cent at the rear while the new Bilstein TDX shocks allow continuously variable damping. Although the steering and damping hardware is from third-party suppliers, the control software is Porsche’s own,” it adds.
According to Motortrend, the brake system is controlled using an electric booster, while the brake pedal is made from an organic sheet composite consisting of steel, carbon fiber, and plastic.
It adds that it weighs 41 per cent less than the 991’s pedal, helping deliver more immediate response and better feel while standard brakes on the 992 Carreras are steel, but because the bigger rear wheels can handle more braking force, the rear rotors have been increased in size from 13.0 inches to 13.8 inches.
It says, “The 992 also debuts a clever new driver-assist feature called Wet mode. Acoustic sensors mounted in the front wheelwells detect water spray, and once the intensity reaches a certain threshold, the control system recommends the driver select Wet mode.
“This changes the brake, alters throttle and stability control mapping, reduces rear diff lock, deploys the rear spoiler to increase downforce, and, in the 4S, channels more torque to the front wheels. A quick ride on a soaked autocross course with a Porsche test driver showed Wet mode to be very effective in keeping the new 911 calm and controlled, even with exaggerated steering and throttle inputs.”
Motortrends notes that although the new 911 is designed to be all about the drive experience, it now offers a lot of Volkswagen Group driver-assist technologies, including adaptive cruise control with stop-start capability, plus lane keeping assist with traffic sign recognition, surround-view park assist, and night vision.
