Porsche Doppelkupplung (PDK) as standard
For the first time in a new Porsche model range, all variants of the Macan feature the high-performance seven-speed PDK as standard.

The advantages of this transmission design include excellent start-up performance, extremely fast gear changes without any interruption in tractive force, highly spontaneous and targeted responses to changes to the accelerator pedal, swift adaptation to a more economical or sporty driving style, low fuel consumption and outstanding shift comfort. The PDK’s intelligent management system allows it to adapt to the required driving profile. As in virtually all Porsche vehicles that feature the PDK, there are two shift gates: On the right, the required switching level is engaged via the typical Porsche gear selector, while the left-hand gate can be engaged manually, or with the standard shift paddles on the steering wheel.

The automatic start/stop function is integrated in the PDK and shuts off the engine as soon as the Macan brakes to a speed of two km/h – even when Adaptive Cruise Control (ACC) is activated. When the brake is released, the engine is restarted quickly and smoothly by the system. A symbol in the instrument cluster display shows the driver that the start/stop function is activated. The audio and communication systems remain on even when the engine is switched off, and the standard two-zone climate control continues to maintain the selected temperature. The automatic start/stop function can be deactivated and reactivated via a button in the centre console.

What’s more, the PDK provides every Macan with the ability to “coast”: When drivers lift their foot off the accelerator, the PDK automatically decouples the engaged gear and the vehicle coasts in neutral until the required speed is reached. The driver is alerted to the fact that the vehicle is in coasting mode by the rev counter dropping to idle speed. When the accelerator pedal or brake is actuated, the PDK selects the appropriate gear once again and engages the clutch. Alternatively, it is possible to trigger coasting by manually shifting beyond the highest possible gear for the respective speed. When the brake is actuated, the engine is automatically and smoothly engaged again in a matter of milliseconds, and the engine braking effect also reduces the free-wheeling distance. Engine engagement is equally swift when the driver presses the accelerator pedal. In practice, the coasting function can save up to one litre of fuel per 100 kilometres, depending on driving profile. The efficiency of the function supports a prudent and relaxed driving style.

Electro-mechanical power steering

Electro-mechanical power steering is another of the efficiency technologies in use in the Macan: Thanks to this feature, the electric motor is only supplied with energy if steering intervention takes place – the advantage for fuel consumption being a saving of up to 0.1 litres per 100 kilometres.

Radiator shutters

Depending on the driving situation and cooling requirements, the radiator shutters on the Macan can also be closed – a function that is controlled by the engine management system. This serves to regulate the air volume that flows through the air intakes. Closing the shutters improves aerodynamics and ensures a low level of drag, thus resulting in lower fuel consumption.

Underbody shield

Similarly, the underbody shield keeps drag to a minimum by optimising the air flow under the vehicle and reducing turbulence. Covering the underbody also enables the air flowing by to be directed to certain areas in a targeted manner.

Electrical system recuperation

Electrical system recuperation is another of the efficiency measures featured in the Macan: This concept charges the battery more intensely during the braking and overrun phases. Restricting the charging current of the generator when the battery is fully charged in turn reduces the load on the combustion engine during acceleration phases because the engine does not have to use as much power to charge the battery.

Thermal management

The intelligent thermal management system in the Macan manages the temperature of the engine and transmission to reduce friction losses during the warm-up phase following a cold start. To do this, the thermal flows are managed in a targeted manner and the different coolant circuits are switched on gradually when needed, allowing the engine and transmission to heat up faster. In addition to improving the internal efficiency of the drive, there is less friction between moving parts, resulting in lower fuel consumption and CO2 emissions. When adopting a sporty driving style, the thermal management system also reduces the temperature level, supporting the demand for high performance by optimally filling the cylinders.
Driven by a need to extract maximum performance from the existing fuel reserves, efficiency has always been at the heart of successful sportscar design. With its drive technology and efficiency technologies, the Macan stands in the finest tradition of sportscars, putting it at the top of its segment.
