Porsche has announced changes to its 2012 Cayenne that provide more power, increased efficiency and a few options that weren't available before.
When it comes to power, the Cayenne Turbo already packs a 500-horsepower punch, but if that isn't good enough for you, Porsche is now offering a kit that boosts power to 540 horsepower and 553 pound-feet of torque; an improvement of 40 ponies and 37 lb-ft. That increase comes courtesy of a pair of new turbochargers with titanium-aluminum turbine wheels and engine electronics adjustments. The added power will net you a 0-62 time of 4.6 seconds (from 4.7 seconds) and a top speed of 176 miles per hour. Porsche also improved brake cooling to help stop this raging locomotive, and the optional Ceramic Composite Brakes now feature larger front discs to boost stopping power.
The diesel-powered Cayenne has also received a significant upgrade, with a cleaner diesel engine that is more powerful and efficient than before. Output has been bumped by five ponies to 245 hp, and the automaker claims the oil-burning SUV consumes only 7.2 liters of diesel fuel per 100 km. That's 39 imperial mpg, or roughly 32 mpg in U.S. mpg. The added performance also improves acceleration, with a quoted 7.6 seconds to reach 62 miles per hour, or . 2 seconds quicker than the 2011 Cayenne diesel. Engine improvements include a new turbocharger, an amazing 44 pounds of weight savings (just from the diesel engine!) and a 10-percent increase in direct injection pressure.
Porsche also announced minor changes meant to improve the Cayenne Hybrid's driving characteristics and the addition of Lane Change Assist to the 2012 Panamera. There's a slew more detail changes outlined in the Porsche press release that you'll find after the break.

The improvements have been achieved through a package of measures, from the use of new materials to reduce weight, lower frictional resistance to a revamp of the injection system, along with a new turbocharger and enhanced thermal management. In detail, the crankshaft for example has been redesigned; fewer counterweights and hollow bores make it lighter and thus more free-revving than before. Direct injection pressure increased by 200 to a maximum of 2000 bar, with a direct impact on the quality of mixture formation. The variable geometry turbocharger is also a new design with optimised bearings and a new compressor wheel, which translates into improved response and greater efficiency. The package of measures also sliced 20 kilograms off the weight of the V6 engine, cutting the unladen weight of the Cayenne Diesel to 2080 kilograms.
Improvements to the Cayenne S Hybrid as well: It offers even more specific driving experiences thanks to modifications to the hybrid manager. If the conditions are right, it is now possible even from a cold start to drive and manoeuvre at low speed on electric power alone. Previously, driving and manoeuvring on electric power after starting the engine was only possible once the operating temperature had been reached.
The new model year also heralds the availability of new Porsche Exclusive options for the Cayenne models. As with the Panamera Turbo, a power kit is now on offer for the Cayenne Turbo as well, boosting the maximum power by 40 (29 kW) to 540 hp (397 kW). Maximum torque increases to 750 Nm. Performance also improves to 4.6 seconds (minus 0.1 s) for the sprint from 0 to 100 km (62 mph) and to a top speed of 281 km/h (176 mph). Fuel consumption and emissions remain unchanged: Even with the optional power kit, the Cayenne gets by on 11.5 litres per 100 kilometres (24.6 mpg imp.) in the NEDC, or 270 g/km CO2.
The increased power is partly achieved by two new turbochargers with titanium- aluminium turbine wheels and adjustments to the engine electronics, resulting in yet further perceptible improvements in the engine's response. The greater power is not without consequences for the braking system. The cooling of the brakes has been further improved and the optional Porsche Ceramic Composite Brake (PCCB) provides deceleration courtesy of larger front brake discs, now with 420 millimetre diameter. An optional 20 inch collapsible spare wheel is available for vehicles equipped with this system.
In addition to the Bi-Xenon main headlights in black including Porsche Dynamic Light System (PDLS) and quad sports tailpipe look, other Porsche Exclusive options for the Cayenne's exterior for the first time feature tinted LED rear lights.
For the Cayenne's interior, Porsche Exclusive is also offering numerous new options for visual customisation for the coming model year, for example new decorative stitching and leather packages as well as the precious wood, Yachting Mahogany.
The offering is rounded off by the milled aluminium Tiptronic-S gear selector and new stainless steel and carbon door entry guards.
The range of options for the Panamera model line has also been enhanced. The Lane Change Assist system adapted from the Cayenne will be available from autumn 2011. It monitors the area behind and to the side of the vehicle as well as the blind spot and informs the driver via a signal in the exterior mirror if the system has located another vehicle in the adjacent lane. The Lane Change Assist system can be activated by a switch on the driver's door and operates between 30 and 250 km/h (19 and 156 mph).
New Porsche Exclusive options for the Panamera exterior are Bi-Xenon main headlights in black including Porsche Dynamic Light System (PDLS) as well as a redesigned sports tailpipe. An additional novelty is the "wireless Internet access" option. From June 2011 onwards this will allow you to go online in the Panamera
