For the 2011 Porsche Cayenne Turbo, Swiss tuner Sportec has developed the SP580 program. The vehicle now features an ECU-remap that gives the 4.8 liter V8 turbo an output of 580 PS (427 kW / 572 bhp) and 700 Nm (516 lb-ft) of torque over the series' 500 PS (368 kW / 493 bhp) and 600 Nm (442 lb-ft). This enables the vehicle to go from zero to 100 km/h in 4.4 seconds compared to the series' 4.7 seconds.
Top speed also gets a boost to 285 km/h (177 mph) from the production model’s 278 km/h (172 mph). The Cayenne Turbo has been fitted with a stainless-steel rear muffler and 90 mm tailpipes while the brakes are fitted with 6-piston calipers at the front axle and 4-piston calipers at the back.
Both have ventilated discs. The vehicle features a set of in-house 22-inch Mono/7 forged wheels in 10.5 x 22 dimensions with 295/30 ZR22 Michelin tires.
Lowering the air suspension on the Cayenne Turbo by 30 mm is achieved by means of the electronic suspension control module.
The engine inside the Cayenne features an upgraded version of the one already equipped to the brand’s previous models. These includes the Porsche Cayenne with its 3.6-liter V6 engine whose output has been boosted to 300 hp, Cayenne Diesel with the turbodiesel 3.0-liter V6 engine that delivers high torque, and finally the Cayenne S and Cayenne Turbo, both of which have the outstanding 4.8-liter V8 engine.
While the engines have indeed been upgrades, its basic features have been improved as well. This results to a slight increase in the output of the engine while at the same time considerably lowering the fuel consumption. Unlike in previous models, the Porsche Cayenne will now have the map-controlled thermal management that will control all of the processes that happen inside the vehicle. Part of this management system is the radiator whose two cooling circuits can be activated as a function of its coolant temperature through the thermostat.
This allows for an on-demand and automatic interruption of its coolant supply, provided that the engine remains to be cold. The result is that the engine is able to warm up faster but also lower the friction, emissions, and fuel consumption, especially during the warm-p stage.
Depending on how much the temperature in the engine increases, the coolant flows through the small circuit in the engine while the vehicle is warming up which then activates the main radiator due to the operating point of the engine, or the main coolant circuit. This thermal management system lowers fuels consumption by as much as 1.5% and thus ensures that the warm-up period is shorter especially if its engine is started cold.
All of the new versions of the Cayenne that has the Tiptronic S will also include on its transmission a separate thermal management system. The goal is the same, and that is to achieve the optimum operating temperature in the fastest time possible so that the friction losses are minimized. This is the reason why the Tiptronic S 8-speed transmission has its heat exchanger, located on the coolant circuit, connected directly with the engine’s cooling circuit.
The effect of this is that it allows faster use of heat which warms up the engine coolant faster when needed and also warms up the transmission to the best operating temperature giving it greater efficiency. Another function that helps low fuel consumption is its on-board network recuperation. This particular system, for all of the Cayenne’s new versions, shifts to the alternator the generation of the energy needed to charge the starter battery.
This is also the alternator that produces the energy need to apply the brakes as the vehicle starts to slow down. This ensures that part of its kinetic energy is kept in its starter battery. When accelerating or being driven at a steady speed, the alternator provides less energy which in turn means that the power to the on-board network is provided mainly from the starter battery that has been charged while the brakes are being applied.
What this means is that the combustion engine is relieved of the need to charge its alternator and thus lowers the fuel consumption. Take for example the New European Driving Cycle, the recovered energy that supplies the vehicle’s on-board network helps lower the fuel consumption by as much as 0.15 liters for every 100 kilometers.
