Engines
At Porsche, there are no conventions. Forbidding free thought? That’s forbidden. The only thing that matters is this question: how can we become even better? Let’s put it another way: can we redefine the limits of engineering? Can we reconcile apparent contradictions? Yes, we can. With Intelligent Performance.
The new 911 answers questions about the future of the sports car with a quantum leap in performance. By reducing fuel consumption, but not by suppressing emotions. By following a principle that has already changed everything once before: in 1974, with the first 911 Turbo.
Developed completely from scratch, the six-cylinder twin-turbo engines of the 911 Carrera and Targa 4 models with a displacement of 3.0 litres embrace this principle and perfect it in a forward-looking way. To be more precise: tremendous acceleration force even in the low rpm range is supplemented by the engine map of a 911 Carrera with the high rev limits typical of a sports car. In other words, high compression and a high engine speed combined with good modulation of power output and surprisingly low fuel consumption, thanks to the reduced overall displacement.
Expressed in figures, this means an extra 15 kW (20 hp) of power, an extra 60 Nm of torque and engine speeds of up to 7,500 rpm. And a considerable reduction in fuel consumption of up to 13 %.
The engine of the 911 Carrera and 911 Targa 4 models develops 272 kW (370 hp). The maximum torque of 450 Nm is available from as low as 1,700 rpm. With Porsche Doppelkupplung (PDK), the 911 Carrera can accelerate from 0 to 100 km/h in only 4.4 seconds and reach a top speed of 293 km/h.
The propulsive potential of the engine in the S models, featuring upsized turbochargers and independent exhaust system, is even more impressive. It generates a power output of 309 kW (420 hp) and the maximum torque is a mighty 500 Nm, available from as low as 1,700 rpm. With Porsche Doppelkupplung (PDK) and Launch Control, the 911 Carrera S sprints to 100 km/h in a mere 3.9 seconds. Top speed isn’t reached until 306 km/h.
What cannot be expressed in figures: the legendary sound of a 911 six-cylinder horizontally opposed engine. And the experience is all the more intense for it.
The stand-out qualities of the new twin-turbo engines are their extraordinarily direct responsiveness and wide torque plateau, reached early in the low end of the rpm band. Combined with the high rev limit – and the legendary sound of a 911 six-cylinder horizontally opposed engine. In short: excellent performance that feeds back to the driver in an instant.
Turbochargers.
The displacement of the new 911 models has been considerably reduced with the aim of cutting fuel consumption. That’s because we more than most as a sports car manufacturer bear huge responsibility. Nevertheless, the power output of the new engines has been significantly increased. Responsible for that are the turbochargers developed for the 911 completely from scratch.
The drive system is a twin-turbo configuration. It has two turbochargers with one charge-air cooling for each cylinder bank. Both turbos are particularly compact and have been optimally adapted to the displacement and power output of the engine. This construction minimises the inertia of the drivetrain and improves responsiveness. The new turbochargers leave the sceptics in their wake and find a new destination: unexplored levels of torque.
What looks technical on paper has an unmistakably resonant sound. The sound of a 911. And a performance that hits the driver in an instant. In the form of direct acceleration and visceral forward thrust. Rather like a ‘thump’ in the back the moment the engine unleashes its unadulterated power.
Active air intake flaps
The active air intake flaps in the front air intakes act to reduce fuel consumption during everyday trips and to achieve superlative performance on sporty drives. Already proven on the 918 Spyder, the flaps close automatically while the car is in motion and thereby reduce drag.
On demand or in SPORT, SPORT PLUS or PSM Sport mode, the flaps open and help to provide optimum engine cooling.
This means that cooling air is supplied only to the extent that it is actually needed. That’s efficiency. Of the intelligent kind.

Efficiency-enhancing technologies. Auto start/stop switches off the engine when the driving speed falls below 7 km/h under moderate deceleration, such as when you are approaching a red light. As soon as you release the clutch or, with PDK, depress the accelerator pedal, the engine restarts – swiftly and smoothly.
In conjunction with Porsche Doppelkupplung (PDK), a coasting function becomes available where the situation allows. The engine is decoupled from the transmission to avoid deceleration caused by engine braking. In this way, optimum use is made of the vehicle’s momentum, enabling it to coast for longer distances.
Sports exhaust system.
It’s a first for any Porsche turbocharged boxer engines, and it’s a technical innovation. Available as an option for the new 911, the sports exhaust system features two catalytic converters and a rear silencer, which lead into two centrally positioned tailpipes. For a look otherwise more likely to be seen on the racetrack. For impressive resonance and an intense sports car sound – typical of the 911. For 100 % Porsche. And for goose bumps at the push of a button.
