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.
