Fitted as standard, the SPORT button enables you to select a suspension setup where the emphasis is on either comfort or sporty performance. At the push of a button, the electronic engine management system switches the engine mapping to offer an even sharper response. In conjunction with the Sport Chrono Package (standard in the 911 Turbo S and the 911 Turbo S Cabriolet), the overboost function is then active and the dynamic engine mounts much firmer.
In SPORT mode, Porsche Doppelkupplung (PDK) ensures that upshifts take place at higher engine speeds and downshifts happen sooner. Coasting mode and the auto start/stop function are deactivated.
The Sport Chrono Package including dynamic engine mounts is standard in the 911 Turbo S models and available as an option for the 911 Turbo and the 911 Turbo Cabriolet. This integrated system provides simultaneous enhancement for the chassis, including rear-axle steering, engine, transmission and aerodynamics.
The main features include a digital and analogue stopwatch mounted on the dashboard, a performance display in the Porsche Communication Management system (PCM), the SPORT PLUS button and the overboost function.
On activation of SPORT PLUS mode, the electronic engine management makes the engine even more responsive, Porsche Active Suspension Management (PASM) and Porsche Dynamic Chassis Control (PDCC) – standard in the 911 Turbo S models – switch to SPORT PLUS mode and a harder damping setting, more direct steering on bends and much better roll stabilisation. And the rear-axle steering reacts more directly – for even more agile steering. As part of Porsche Active Aerodynamics (PAA), the front spoiler and rear wing are also included in the performance setting in SPORT PLUS mode. So you can make full use of the performance potential of your 911 Turbo – especially on the racetrack.
In SPORT PLUS mode, the trigger threshold for PSM is raised. Agility is perceptibly enhanced when braking for corners with PSM, allowing sportier braking and exit acceleration. For maximum dexterity, PSM can be set to standby while the car is still in SPORT PLUS mode. Although, for safety, it’s still there in the background.
With the SPORT or SPORT PLUS button active, under full acceleration, the maximum boost pressure in the lower and medium speed ranges is now temporarily increased by approximately 0.15 bar: the overboost. Engine torque is also boosted by 50 Nm for a short time – to 710 Nm in the 911 Turbo and the 911 Turbo Cabriolet. In the 911 Turbo S models it goes up to 750 Nm.
The Sport Chrono Package has two additional functions. For a sporty drive that borders on a motorsport experience. The first function is Launch Control. When performing laps, for example, this helps you achieve optimum acceleration from a standing start, a racing start in other words.
The second function is the ‘motorsport derived gearshift strategy’. Using this, PDK is geared up for the shortest possible shift times and optimum shift points for maximum acceleration. Ideal for the racetrack.
Another key component of the Sport Chrono Package is the stopwatch mounted on the dashboard. The PCM has a special performance display to view, store and evaluate lap times or other driving times.
