The Sport Chrono Package Turbo with dynamic engine mount system is standard on 911 Turbo S models and available as an option for 911 Turbo models. This integrated system provides simultaneous enhancement for engine, chassis and transmission.

Key features include a digital and analogue stopwatch on the dashboard, a performance display, a personal memory function in the Porsche Communication Management (PCM), the SPORT button and – in combination with PDK – the SPORT PLUS button, and an additional display on the steering wheel which informs the driver if the SPORT buttons and Launch Control have been activated. The 911 Turbo models additionally offer the ‘overboost’ function. This is how it works:

When ‘Sport’ mode is selected, the engine management system creates a much more aggressive response to pedal inputs. To do this, it implements an alternative throttle map which relates the pedal position in the footwell to a wider angle of opening in the throttle body. In higher gears, it uses a hard rev-limiter to protect the engine under power.

In the 911 Turbo models, under full acceleration, the maximum boost pressure in the lower and medium speed ranges is now temporarily increased by approximately 0.2 bar. As a result, engine torque is boosted by 50 Nm to a maximum of 700 Nm for a limited period. (The 911 Turbo S models are configured to operate with a higher boost pressure level, which means that their maximum torque is always 700 Nm.)

In addition to the engine, ‘Sport’ mode is enabled in the standard Porsche Active Suspension Management (PASM) suspension. The dampers become firmer, enabling faster turn-in as well as better contact with the road.

In automatic mode of PDK, the basic gearshift pattern is switched to high-performance mode. The gear change action is virtually instantaneous, while the shift points are timed for maximum acceleration. Lift off the throttle – even at high revs – and the system automatically shifts down to apply engine braking. In manual shift mode, gear changing is faster and more dynamic.

Porsche Stability Management (PSM) is also adapted, with the intervention threshold raised. As a result, the car has a more natural response to lateral and longitudinal forces. Cornering agility is greatly enhanced, when both braking to turn in and applying power on exit – particularly in low-speed bends. For even greater driving pleasure.

For maximum manoeuvrability, PSM can be partially disabled while the car is still in ‘Sport’ mode. PSM simply monitors the forces acting on the car and will only intervene in the most critical scenarios, e.g. when ABS assistance is required on both front wheels.

In conjunction with PDK (standard on 911 Turbo S models), the Sport Chrono Package Turbo with dynamic engine mount system has two additional functions that can be activated via the SPORT PLUS button, for a sporty drive that borders on a motorsport experience.

The first function is ‘Launch Control’, which, for example when performing laps, helps you achieve optimum acceleration from a standing start, a racing start in other words.

The function works like this: press the SPORT PLUS button when the transmission is in ‘D’ or ‘M’. Then, with your left foot, press the brake pedal and accelerate fully with the right foot. The car recognises ‘Launch’ mode from the accelerator kickdown action and adjusts the engine speed to the optimum level, which is around 5,000 rpm. At the same time, boost pressure is increased to approximately 0.5 bar, engine torque is increased and the clutch is applied lightly. ‘Launch Control’ now appears in the steering wheel display. Now release the brake as quickly as you can – and feel the acceleration power unleashed to the road.

The second function is the ‘motorsport-derived gearshift strategy’. Using this, Porsche Doppelkupplung (PDK) is geared up for the shortest possible shift times and optimum shift points for maximum acceleration – ideal for the racetrack.

A key component of the Sport Chrono Package Turbo with dynamic engine mount system is the stopwatch mounted on the dashboard. Porsche Communication Management (PCM) has a special performance display to view, store and evaluate lap times or other driving times. It shows the total driving time, lap distance, lap number and the lap times recorded so far. You can view the current fastest lap and the remaining range until empty. Travelled distances can be recorded and benchmark times defined.

The personal memory function of the Sport Chrono Package Turbo can also be used to store personalised settings for a range of systems, including the orientation lighting or air conditioning.
