Specific characteristics:
The 911 Turbo is a prime example of the ongoing evolution of Porsche engineering. For another step up in all-round performance, there’s the optional Sport Chrono Package Turbo with dynamic engine mount system and overboost. This integrated system provides simultaneous enhancement for engine, chassis and transmission.
Key features include the ‘overboost’ function, a digital and analogue timer located on the dashboard, a SPORT select button on the centre console, a performance display and personal memory function in the standard Porsche Communication Management (PCM) 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.
When ‘Sport’ mode is selected, the EMS SDI 3.1 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.
Under full acceleration, the ‘overboost’ function provides a temporary increase in available boost pressure of approximately 0.2 bar. The overboost is applied across the low and medium rev ranges, briefly raising the standard 650 Nm of torque to as much as 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 the optional 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, 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 PDK steering wheel display. Now release the brake as quickly as you can – and feel the acceleration power of the new 911 Turbo models.
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 Plus with dynamic engine mount system is the timer 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 Plus can also be used to store personalised settings for a range of systems, including the orientation lighting or air conditioning.
