2021 Porsche Turbo now available from Sime Darby Auto Performance

For more than 4 decades, the Porsche Turbo has been the top of the company’s range, offering superlative performance and optimum driving dynamics. The latest generation 911 Turbo S is now officially available from Sime Darby Auto Performance (SDAP), priced from RM2,235,463 (with 50% exemption of sales tax until June 30, 2021).

New 6-cylinder boxer engine
The latest model has a new 3.8-litre 6-cylinder boxer engine with two VTG turbochargers, and delivers 650 ps/800 Nm. Based on the 911 Carrera engine generation, it features a completely redesigned air-cooling system; new, larger turbochargers in a symmetrical layout with electrically adjustable wastegate flaps, as well as the use of piezo injectors, which have significantly improved the vehicle’s characteristics with regard to responsiveness, power, torque, emissions and revving ability.

With 8 gears in the PDK optimised for the turbocharged engine, the 0 to 100 km/h acceleration time is said to be two-tenths of seconds quicker than before but the top speed is still 330 km/h. Thanks to the enhanced Porsche Traction Management all-wheel drive system, the transfer case can distribute significantly more torque, with up to 500 Nm being transferred to the front wheels.

Modified track widths, further developed aerodynamics and new mixed-sized tyres contribute to the agility and sportiness of the new 911 Turbo S. The track is now 42 mm wider at the front axle and 10 mm wider at the rear axle.

The body dimensions have also been increased significantly in line with the enhanced driving dynamics, with an added 45 mm above the front axle (1840 mm) and an increase of 20 mm in overall width above the rear axle (1900 mm).

Adaptive aerodynamics
Porsche Active Aerodynamics (PAA) adapts the aerodynamic characteristics even more precisely to the driving situation, speed and selected driving mode. This resolves the age-old aerodynamic configuration dilemma: the contradiction between a low drag coefficient for maximum speed and low consumption, and high downforce for better driving dynamics.

The comprehensive expansion of PAA makes it possible to achieve a much larger spread between the aerodynamic configurations for optimum driving dynamics and minimum drag. The adaptive aerodynamics now include controlled cooling air flaps at the front and a larger rear wing for even more downforce.

The active cooling flaps, together with the variable front spoiler lip as well as the larger extending and tilting rear wing which delivers 15% more downforce, offers 3 active aerodynamic components, depending on the speed and driving mode. In the newly available Eco configuration, the rear wing is retracted over a large speed range so that the vehicle can be driven with minimum drag.

Wet Mode
Also new is a ‘Wet mode’ which enhances driving stability in wet conditions. The extended but not yet tilted rear wing combined with the completely retracted front spoiler lip shifts the aerodynamic balance towards the rear axle when the Wet mode is activated. This results in a higher rear-end and driving stability for greater safety on wet road surfaces.

In the event of full braking at high speed, the new airbrake function will be activated automatically. The front spoiler and rear wing are moved to the Performance position for higher drag and increased downforce to reduce the braking distance and improve driving stability during braking.

For the first time, the 911 Turbo S is factory-fitted with mixed tyres in two different sizes: 20-inch tyres with unique 255/35 dimensions at the front, and 21-inch 315/30 tyres at the rear.

High quality sporty finish
The interior has a high-quality and sporty finish. Standard equipment includes a full leather interior and carbonfibre trim in combination with Light Silver accents. The 18-way adjustable sports seats have stitching that pays homage to the first 911 Turbo (type 930). High quality graphic elements and logos in the instrument cluster complete the characteristic Turbo S features.

The centre screen of the PCM is now 10.9 inches and can be operated quickly without distraction, thanks to its new layout with significantly reduced number of controls. Other features on board are the GT sports steering wheel, the Sport Chrono package with newly integrated Porsche Track Precision app and BOSE Surround Sound system.

“The Porsche Turbo designation is synonymous with outstanding performance, even when it was first introduced. The forefather of all Turbos (the 930 generation) was indeed a technical revolution in car production and has been improved time and time again. This is even more so with the new 911 Turbo S. While it performs at the level of a supercar, the daily driveability remains outstanding. It is this flexibility to react to different situations that makes the 911 Turbo S a personal favourite of mine. Combining unprecedented power, driving dynamics and comfort with efficiency builds a bridge from tradition to innovation with this new generation,” said Christopher Hunter, CEO of Sime Darby Auto Performance.

Adaptive aerodynamics in the new Porsche 911 Turbo S

Aerodynamics play a very important role in a car’s performance, especially for high-performance cars. Where efficient aerodynamics will help a car improve its fuel efficiency, for high-performance cars, it also enhances stability and makes the car safer to driver at the very high speeds it is capable of.

Porsche has continuously improved the aerodynamics of its 911 model from generation to generation, often coming up with innovations that set new standards. For the latest 911 Turbo S, the aerodynamic characteristics of the car can be even more precisely adapted to the driving situation, speed and selected driving mode.

Active aerodynamic elements
Porsche Active Aerodynamics (PAA) features active aerodynamic elements that resolve the conflicts between different aerodynamic goals. The comprehensive expansion of the intelligent system in the 911 Turbo S makes it possible to achieve a much larger spread between the aerodynamic configurations for optimum driving dynamics and minimum drag.

The active cooling air flaps are new. together with the variable front spoiler lip as well as the extending and tilting rear wing, the new top-of-the-range model therefore features three active aerodynamic components. On top of the basic aerodynamic configurations of the 911 Turbo, namely PAA Speed and PAA Performance, this now permits realisation of an Eco configuration.

PAA has also been extended to include a Wet Mode function, which moves the aerodynamic balance towards the rear axle for greater driving stability in wet road conditions, as well as the airbrake function, which produces higher drag and greater downforce in the event of full braking at high speed and therefore results in a shorter braking distance and greater driving stability.

Adaptation to the changed airflow around the car also occurs when the sliding roof or convertible top is open. This means that there are a total of 8 different aerodynamic configurations, which are each described by a specific combination of the active aerodynamic components.

Improvements have not just been made in adaptation to the specific requirements in driving operation but also as regards the aerodynamic properties themselves: the newly designed active front spoiler and rear wing have increased the downforce by 15% to guarantee enhanced driving stability and dynamics at higher speeds.

The maximum downforce in the Performance position (Sport Plus mode activated) is now around 170 kgs. The drag coefficient (Cd) of the 911 Turbo S varies depending on the aerodynamic setting. The most efficient configuration has a minimum value of 0.33 Cd achieved with closed flaps and retracted front and rear spoilers.

The cooling air flaps
The newly developed controlled cooling air flaps permit a lower driving resistance and thus reduced fuel consumption. The flaps are located in the right and left air intakes of the front apron. They are continuously adjustable and control the cooling air throughput through the radiators.

Front spoiler with pneumatic actuation
The active front spoiler has been significantly enhanced, with its effective aerodynamic area increased compared with the predecessor. Extension and retraction can now take place in a shorter time with lower pressure.

Three segments can be inflated separately with the help of actuators. The two outer actuators always function synchronously. The front spoiler is made of a flexible plastic (elastomer) and can therefore be rotated so that the middle segment can be retracted or extended when the outer segments are extended.

Rear wing with more functions
The rear wing on the 911 Turbo has always been a distinctive feature. In the latest model, its lightweight construction makes it 440 gms less than the corresponding component of the predecessor but with an 8% larger effective area. Electric adjustment of the wing – which can be extended and tilted – is performed primarily depending on the speed and selected driving mode. There is now an Eco position with the wing retractable over a large speed range so that the car can be driven with minimum drag.

Wet mode and airbrake
With the new Wet mode, the focus is on driving stability in wet conditions. If the in the front wheel housings detect a significantly wet road surface due to spray that is swirled up, a corresponding message is displayed to the driver in the instrument cluster. The driver can then manually activate Wet mode by means of a rotary switch on the steering wheel.

The new airbrake function is activated automatically in the event of full braking at high speeds. The front spoiler and rear wing are then moved to the Performance position. The higher drag and increased downforce can reduce the braking distance. Driving stability is also improved during braking.
