STUTTGART -- Porsche is polishing the sporty credentials of its third-generation Cayenne by reducing weight, adding horsepower and introducing new steering and suspension features to improve the SUV's cornering and boost acceleration.
The Cayenne's 3.0-liter engine has its power increased by 40 hp to 335 hp while the 2.9-liter V-6 boosts output by 20 hp to 434 hp. The fastest version will accelerate from 0 to 100 kph (62 mph) in 4.9 seconds and has a maximum speed of 265 kph (165 mph).
Porsche’s flagship SUV was unveiled here on Tuesday ahead of its debut at the upcoming Frankfurt auto show. It will come with rear-axle steering already available in the 911 and Panamera, which gives the vehicle a tighter turning radius and helps with high-speed maneuvering. A new eight-speed Tiptronic S transmission offers shorter response times and sportier gear ratios.
To save weight, the sheet metal of the Cayenne is made out of aluminum, the second Porsche model whose exterior is entirely stamped out of the lightweight material after the Panamera. A lightweight lithium ion polymer starter battery also helps cut weight. At 1,985 kg (4,376 pounds), the Cayenne weighs up to 65 kg less than the outgoing model.
The Cayenne is longer and lower which helps to give it a more streamlined look and boost interior space. At 4918 mm (194 inches), its length has grown 63 mm while the wheelbase is unchanged at 2895 mm and roof height is reduced by 9 mm. The luggage compartment volume increases by 100 liters to 770 liters.
The SUV's driving dynamics are improved with standard active all-wheel drive. The Cayenne's wheel sizes are an inch bigger at 19 inches with wider tires on the rear axle for the first time to improve driving dynamics in corners. Optional cast-iron brake discs are available, coated with a tungsten-carbide layer to increase fiction while reducing wear.
The Cayenne gets Porsche's 12.3-inch high-definition touchscreen, launched last year with the new-generation Panamera. Safety equipment includes night-vision assistance with a thermal imaging camera, along with lane changing and lane-keeping assistance.
