"For the first time ever, the 911 GT3 models are equipped with Traction Control (TC) as standard. This higher rev limit allows a closer drop between individual gear ratios and thus faster acceleration." Thanks to this and other performance-oriented features, the new 911 GT3 engine has a maximum speed of 8,400 rpm. The inlet and exhaust valves, for example, use ultralight tappets with hydraulic valve clearance adjustment. The valvegear also features intelligent design solutions originally developed for racing engines. Ultra-lightweight connecting rods and specially lightened pistons help to further reduce the oscillating masses, enabling a more dynamic, free-revving throttle response. Each of these parts is, of course, designed for the unique challenges of endurance racing. Maximum speed is 310 km/h (193 mph).Īll components in the engine cooling system are directly sourced from the Porsche Motorsport division. The benchmark sprint to 100 km/h (62 mph) requires as little as 4.3 seconds. Indeed, the new 911 GT3 offers more power per unit of engine displacement than any other naturally aspirated production Porsche. Maximum engine speed is 8,400 rpm.Įven more impressive is the high specific output in excess of 115 bhp per litre. When 'Sport' mode is selected, as much as 25 Nm of additional torque is available in the medium rev range, i.e., below the point of maximum torque. Maximum torque of 405 Nm is available at 5,500 rpm. Naturally aspirated, it develops 305 kW (415 bhp) at 7,600 rpm from a total displacement of 3,600 cm3. Special features include four-valve technology and VarioCam variable valve timing. "Powering the new 911 GT3 is a rear-mounted, water-cooled six-cylinder boxer engine. I hope this puts the Sport Chrono question to bed once and for all. (20 and 25 Nm) and an increase in the power output of 13 bhp." This leads to an increase in the torque values of between 15 and 18 ft. In the sports setting the exhaust backpressure in the variable exhaust system is reduced, the gas cycle improved and the torque noticbly increased in the rpm range between approx. (25Nm) in the mid-rpm range and selects a sporty tuning for Traction Control (TC). "When the Sport Button on the center console is depressed this increases the engine torque by up to 18 ft. This is a quote from the 2007 Porsche GT3 Technical Introduction booklet. Your salesperson is thinking of what Sport Chrono does on other Porsche models which does in fact control motor functions but not on the GT3. Sport Chrono on the GT3 only gives you lap timing functions, AC memory functions and some other fairly useless things like that) Using this, PDK is geared up for maximum shift speed, the shortest possible shift times and optimum shift points for maximum acceleration – for uncompromising performance.The sport button which is standard on the GT3 controls those functions (engine, TC limits, exhaust valve, etc). Second, the ‘motorsport-derived gearshift strategy’. The driver now quickly releases the brake – and prepares for maximum acceleration. The message ‘Launch Control active’ appears on the instrument cluster display. Engine torque increases and the clutch closes slightly. With the accelerator in the kickdown position, the system detects the driver's request for Launch Mode and revs the engine to an optimum speed of approximately 6,500 rpm. Whilst the driver depresses the brake pedal with the left foot, the right foot depresses the accelerator pedal to the floor. ‘Launch Control’ is operated via the Sport Plus button with the ‘D’ or ‘M’ drive position selected. In combination with Porsche Doppelkupplung (PDK), the Sport Chrono Package offers two additional functions that are activated by the Sport Plus button.įirst, ‘Launch Control’, which ensures you achieve the fastest possible rate of acceleration from a standing start – on the racetrack, for example.
