The spark plugs should be replaced every 24,000 miles (40,000 km) or four years. Explosive all-weather acceleration The 911 Turbo Coupe is defined by its astounding powerplant. The 3.6-liter horizontally opposed six-cylinder engine features twin turbochargers and readily delivers an awesome 480 horsepower and a locomotive-like 460 lb.-ft. of torque. When equipped with the optional Sports Chrono Turbo feature with Overboost, the driver actually has bursts of 505 lb.-ft. of torque available. The engine's stunning potential is channeled to all four wheels via Porsche Traction Management (PTM) all-wheel drive. This electronically controlled system can vary the torque split infinitely and absolutely between front and rear wheels as needed for optimum traction. Wheel slip is further reined in by Porsche Stability Management (PSM) which is standard on all Turbos. Driving through either a standard-equipment six-speed manual or optional five-speed Tiptronic S transmission, the Turbo Coupe drives from zero to 60 mph in a 3.7 second blur. When equipped with the Tiptronic S, the Turbo Coupe gets to 60 mph in 3.4 seconds. That's 0.3 second faster than the experienced Porsche test drivers could make the run with the manual gearbox. This superior acceleration of the automatic transmission is another example of Porsche's engineers bringing higher levels of performance to a broad range of skilled drivers. Socially responsible performance As astounding as is the Turbo Coupe's brutal acceleration is its miserly fuel consumption. The EPA rates the Turbo Coupe at 23 mpg on the highway. The manual gearbox delivers 16 mpg in the city test, and the Tiptronic S version 15 mpg. Despite its segment leading performance potential, the Turbo Coupe does not carry a gas guzzler penalty. The Turbo Coupe is also certified as a Low Emissions Vehicle, category two (LEV-II) thanks to its engine's efficiency. Besides the twin turbochargers, the 3.6-liter boasts Porsche VarioCam Plus variable intake timing and lift system under the purview of its Motronic® engine controls. Active suspension is standard As the flagship 911, the Turbo Coupe bristles with performance and safety enhancing technologies. Besides the PSM stability system, the Turbo Coupe comes standard with Porsche Active Suspension Management (PASM), which allows the driver to choose the firmness of the suspension. By selecting the Normal mode, the Turbo Coupe driver enjoys a sporting but comfortable ride. Choosing the Sport mode brings a firmer ride for improved performance dynamics. Muscularly aerodynamic Clearly a member of the Porsche 911 family, the Turbo Coupe is instantly identifiable as the top of that range. From its iconic front air intakes, oval Bi-Xenon® headlights, LED directional indicators mounted in the front side cooling-air openings to horizontally split air intakes for the turbocharger intercoolers mounted aft of the doors, the Turbo Coupe's sheetmetal is unique.
