Engines

You could ask whether the sports car is still relevant. It would be a good question, but you might as well ask the same of dreams.

The answer to both questions lies in the future or, to be more precise, in the future of the sports car. In the 911, the future is already here. The highly efficient, state-of-the-art-engines make a considerable contribution to the comparatively low fuel consumption, but their sound is still unmistakably Porsche.

The 911 engines are also unmistakably sporty thanks to the SPORT button fitted as standard. At the push of a button, the engine becomes tuned for a sharper response and engine dynamics that are even more direct.

Advanced Powertrain

How did Porsche engineers balance the sensible with the sensational? The new thermal management technology manipulates heat flow to bring engine and transmission to optimal operation temperatures faster, reducing fuel consumption. Electrical system recuperation reduces the alternator's draw on engine power, freeing it for pure exhilaration. Other benefits come from a choice of two advanced transmissions, including a seven-speed manual gearbox. The first six forward gears have a sport ratio, while the seventh has a long ratio that reduces fuel consumption and engine noise at highway cruising speeds. The optional PDK also employs seven forward gears with a long-ratio top gear for efficient cruising.

Turbochargers

The new 911 Turbo engine adheres to proven Porsche principles: rear-mounted. With six cylinders and a total displacement of 3.8 liters. And the cylinders placed horizontally in two opposite rows—what's referred to as a "flat-six" arrangement. What ultimately transforms a Porsche into a 911 Turbo are its two exhaust-driven turbochargers. Together with Variable Turbine Geometry (VTG), the intake manifold, and VarioCam Plus, the forced induction of compressed air into the cylinders creates stunning performance. On paper or on pavement, there is nothing like a Porsche 911 Turbo.

Transmissions

7-speed manual transmission
Pure, direct, precise. Short shift movements and an optimal transition from one gear to the next. That's exactly what you would expect of a Porsche manual gearbox. The design of this manual gearbox is based in principle on that of Porsche Doppelkupplung (PDK). Gears 1 to 6 have a sports ratio and top speed is reached in 6th gear. The additional 7th gear, however, has a long ratio, which reduces torque and helps to reduce fuel consumption.

Porsche Doppelkupplung (PDK)
The 7-speed PDK is available as an option for all of the 911 models, giving the driver the ability to enjoy driving in either manual or automatic mode, with significant performance and efficiency benefits.

Efficiency-enhancing technologies

Auto Start Stop Function
The Auto Start Stop function is standard in the 911 models. In the 911 equipped with manual transmission, the engine switches off automatically when you come to a stop, select Neutral, and release the clutch pedal. In cars equipped with the optional Porsche Doppelkupplung (PDK) transmission, the engine switches off when you stop and leave your foot on the brake pedal.

Thermal Management
The thermal management system regulates the temperature in the engine and gearbox through the intelligent manipulation of heat flow. In this way, the engine and gearbox reach their optimal operating temperature sooner, reducing fuel consumption through increased combustion efficiency and lubrication performance.

Air-Intake System

This system adjusts the volume of air entering the engine to suit changes in engine speed. It does so by cleverly fine-tuning the air's vibration as it passes through the intake manifold. Benefits include higher torque at low engine speeds, a flatter torque curve, and a sporty sound at higher revolutions. The Carrera S and Carrera 4S operate a two-stage system. The entire intake system is made from a durable, lightweight synthetic material.
