Porsche has taken the wraps off the facelifted Cayenne which comes with a number of modifications.

At a first glance the styling changes appear to be subtle but the 2015 Cayenne comes with a series of visual tweaks, especially at the front where there's a larger grille and a redesigned bumper with more blades in the air ducts to improve cooling. Also revised are the front wings as well as the hood that has grown in size a little bit and appears more contoured than before.

Bi-xenon headlights are installed as standard in the Diesel, S and S E-Hybrid versions which also have four-point LED daytime running lights. Opt for the Turbo model and you get LED headlights with Porsche Dynamic Light System (PDLS). Moving at the back, we notice more angular taillights, updated tailgate as well as a different bumper incorporating the exhaust pipes.

The most important revisions occur under the hood where the Cayenne S has received a new V6 3.6-liter bi-turbo engine developed entirely by Porsche. The motor is capable of generating 420 PS (309 kW) at 6,000 rpm and 550 Nm (406 lb-ft) of torque from 1,350 to 4,500 rpm. It will serve as a replacement for the thirsty naturally-aspirated V8 4.8-liter, offering an extra 20 PS (15 kW) and 50 Nm (37 lb-ft) while being more economical. It needs 5.5 seconds (5.4s with Sport Chrono package) to hit 62 mph (100 km/h) and will reach 161 mph (259 km/h) so it's 0.4s quicker in the sprint and has a 1 mph higher top speed.

As for the Cayenne S E-Hybrid, it makes use of a 3.0-liter V6 supercharged engine with 333 PS (245 kW) working together with an electric motor that provides 95 PS (70 kW) for a combined output of 416 PS (306 kW) at 5,500 rpm and 590 Nm (435 lb-ft) from 1,250 to 4,000 rpm. This hardware setup grants a 0-62 mph run in 5.9 seconds and a 151 mph (243 km/h) top speed while on electric power it can reach 77 mph (124 km/h). It boasts a 10.9 kWh lithium-ion battery pack granting an all-electric range from 18 to 36 km (11 to 22 miles)

Porsche says the Cayenne's chassis has been revised to provide better comfort without affecting the SUV's dynamics. Inside the cabin there's a fresh multi-function steering wheel with shift paddles and the engineers have also improved the model's Auto Stop/Start Plus system.

The 2015 Porsche Cayenne facelift will reach U.S. dealerships on November 1 at a starting price of 61,700 USD for the Cayenne Diesel. Up next is the Cayenne S at 74,100 USD, followed by the Cayenne S E-Hybrid at 76,400 USD and the range-topping Cayenne Turbo priced from 113,600 USD. All these prices exclude the 995 USD destination charges.
