|Scheduled to make their world debut at the North American International Auto Show (NAIAS) in January 2016, the anticipated Porsche 911 Turbo and Turbo S are beefed up by 20hp and adopt a distinctively sharper design, yet suitable for everyday use.|
Available in both Coupe and Convertible versions, the twin-turbocharged, 3.8-liter flat-six engine in the 911 Turbo now has an output of 540 hp. This power gain was achieved by modified inlet ports in the cylinder head, new injection nozzles and higher fuel pressure. The 911 Turbo now develops 580 hp courtesy of new turbochargers with larger compressors. Porsche is still the only manufacturer to utilize turbochargers with variable turbine geometry in petrol engines.
The engines now also have what is known as a ‘dynamic boost function’ to further raise engine responsiveness in dynamic operation. It maintains the charge pressure during load changes i.e. when the accelerator pedal is released briefly. This is achieved by just interrupting the fuel injection, whereas the throttle valve remains open. As a result, the engine reacts with practically no delay to a subsequent press of the accelerator pedal. The effects of this function are more pronounced in the Sport and Sport Plus modes than in Normal mode.
Overall, the new high-performance sports cars attain breathtaking driving performance, while fuel consumption is reduced even further. The 911 Turbo Coupé sprints to 100km/h (62 mph) in 2.9 seconds. Its top speed of 205 mph is eight mph higher than before. The 911 Turbo reaches the 100km/h (62 mph) mark in 3.0 seconds, and its top speed is 198 km/h. Nevertheless, the coupes only consume 9.1 l/100 km, and the convertibles 9.3 l/100 km.
A familiar option on the next generation 911 Carrera, the new 911 Turbo and Turbo S feature as standard the new GT sport steering wheel, 360 mm in diameter and with a design adopted from the 918 Spyder. It features what is known as a ‘Mode Switch’, a rotary ring with stepped positions that is used to select one of the four modes: Normal, Sport, Sport Plus and Individual.
Another new feature of the Sport Chrono Package is the Sport Response button at the center of the mode switch. Inspired by motor sport, at the push of a button it pre-conditions the engine and transmission for optimum responsiveness. In this state, the vehicle can produce instantaneous acceleration for up to 20 seconds, such as during an overtaking move. An indicator in the instrument cluster in the form of a running timer shows the driver the elapsed time. Sport Response functionality can be called up as often as desired, and from any of the driving modes.
Porsche Stability Management (PSM) in the 911 Turbos now has a new PSM Sport Mode. A brief press of the PSM button on the centwe console puts the system in a very sporting configuration, which is independent of the prevailing driving program selected. The separately switched PSM Sport mode alters the PSM intervention threshold much more than was the case in the Sport Plus mode of the previous version.
The chassis of the new 911 Turbos with Porsche Active Suspension Management (PASM) as standard offers an even greater spread between performance and comfort. In addition, the 911 Turbos offer a full complement of equipment for dynamic driving: Porsche Dynamic Chassis Control (PDCC) roll compensation is standard as is the Ceramic Composite Brakes (PCCB) system. New options for the range include the radar-based lane change assist and a lift system for the front axle (increase ground clearance by 40mm at the front spoiler lip during low speeds).
As with the 911 line-up, the newly-developed infotainment system, Porsche Communication Management (PCM) incorporating online navigation, is a feature of the cockpits of the 911 Turbos. This system features a multi-touch monitor with high-quality glass surface, which is perfectly integrated into the center console, and it offers numerous new and extended connectivity functions thanks to the standard Connect Plus module.
