![]() ![]() I’m not sure what Sport Chrono does if you have a GT car with PDK+. Sport+ also tightens up the adjustable shocks.īut in my current GT4 (and all GT cars from Porsche) Sport Chrono mainly is just a timing option for both the analog clock function in the dash and also a track-app timer that uses the start-finish point of the track to automatically log all your lap times and more. But not in Sport+ it is the perfect track setting. In the other two modes, if you are at WOT it still shifts at redline, but anything less and it shifts in a civilized manner. So if you want to run the PDK in automatic at the track it executes perfect redline shifts every time, no matter what your throttle opening is. In Sport+, which I used only for track and up-in-the-mountains work, it holds the shift points to redline every time. E-steering is more responsive, the adaptive motor mounts harden, and the shift points (I had PDK) come later and the shifts come more abruptly. In Sport (which I used for almost all street driving) everything tightens up. In normal everything was relaxed, what I used the few times my wife was in the car. So with my 2015 Carrera GTS it gave you an analog lap timer clock in the center of the dash (okay, that’s not “just software” so I stand corrected, by me.) It gave 3 modes of tuning: normal, Sport and Sport+. But it is exclusively software, as far as I know. The brakes were 380mm diameter at the front and 350mm at the rear.It does (and did) different things for different models, but it’s what enables you to choose different levels of “sportiness” in the tuning maps, along with some other things that get enabled if you pay many extra cash dollars for Sport Chrono. The advantages of this high-tech material mean a reduction of 17Kg compared to the standard brake system, excellent fade resistance owing to consistent friction values, and absolute corrosion resistance. Maximum speed with either transmission is 310 km/h (193 mph).Īs an option, Porsche also offered its ceramic brake system, PCCB (Porsche Ceramic Composite Brake). ![]() Benchmark times to 200 km/h (124 mph) are 12.8 and 12.2 seconds, respectively. The optional Sport Chrono package allows the 911 Turbo to overboost for ten seconds (1.0 bar to 1.2 bar), increasing peak torque over a narrow RPM range.Īccording to official Porsche figures, the 997 Turbo Gen 1 accelerates from a standstill to 100 km/h (62 mph) in 3.9 seconds with the manual transmission, and 3.7 seconds with the 5-speed Tiptronic S transmission. With the exception of the 1988 Honda Legend Wing Turbo and 1989 Dodge Shelby CSX sedan, such variable geometry turbines were previously only available on diesel engines. The Variable Turbine Geometry incorporates guide vanes on the turbine wheel that change their angle of attack with exhaust speed, reducing boost lag at low speeds while opening up to prevent excessive back pressure at high RPM. The engine uses two BorgWarner VTG turbos, a first for Porsche. The turbochargers are fitted with a two-stage resonance intake system. ![]() The engine was based on the rugged and reliable 964/GT1 design rated at 480 PS (350 kW 470 hp) and 620 N⋅m (460 lb⋅ft) of torque. Also featured was a retractable rear wing, as used on the 996 Turbo. Large air vents fore and aft of the rear wheels provide other obvious visual cues of the Turbo model. ![]() It featured a new front bumper with LED turn signal strips in the air intakes the fog lamps were moved to the corners of the bumpers. The 997 Turbo debuted in February 2006 at the Geneva Motor Show. Sport Chrono Package & Carbo-Ceramic Breakesĥ-Speed Tiptronic S Automatic Transmission ![]()
