The 2015 Porsche Cayenne Turbo is one of four models available in the maker's portfolio for the SUV.

Sport-utilities have been zipping off dealer lots this year and Porsche looks to take advantage of that by finally unveiling an update to its popular Cayenne SUV that’s already sold half-a-million copies since its introduction in 2002.

While the 2015 model does get some freshening on the outside, it’s the number of choices in the Cayenne portfolio that catches the eye. For the third iteration, the Porsche presents four options in the U.S.: Cayenne Diesel, Cayenne S, Cayenne Turbo, and Cayenne S E-Hybrid, which is the first plug-in hybrid in the premium SUV segment.

In fact, Porsche brags that it is the only automaker with three plug-in hybrid models in its line-up – the other two being the Panamera S E-Hybrid and the 918 Spyder. Borrowed from the aforementioned Panamera, the new Cayenne E-Hybrid pairs a 3.0-liter supercharged V6 with 333 horsepower to an electric motor with 95 hp for a combined 416 hp.

The result is a zero-to-60 time of about 5.4 seconds. In electric-only mode, it has a top speed of 78 mph and an overall top speed of 151 mph. Both results are significantly better than its predecessor, the Cayenne S Hybrid.

While the performance is impressive, it lags the big boy in the line-up: the Cayenne Turbo. The latest version still uses a 4.8-liter twin-turbo V8, but it now puts out 520 hp and 553 lb-ft for a zero-to-60 time of about 4.2 seconds or 4.1 with the optional Sport Chrono package.

For 2015, the Cayenne Diesel is the entry-level model for the line-up. Not every base model does zero-to-60 in less than 5.4 seconds.

The base model is out for 2015 and the Diesel takes over the bottom rung on the Cayenne ladder. It retains its 3.0-liter turbo diesel putting out 240 hp. However, the Cayenne S gets a 3.6-liter twin-turbo V6 produced entire by Porsche and similar to the one in the Macan Turbo with 420 hp and 406 lb-ft of torque. It does the zero-to-60 mph run in about 5.2 seconds.

The exterior did get some updates as well, including Bi-Xenon headlights, which are standard on the Diesel, S, and S E-Hybrid models, with “hovering” four-point LED daytime running lights. Standard on the Turbo are high performance LED headlights with the Porsche Dynamic Light System (PDLS).

Pricing starts at $61,700 for the Cayenne Diesel, $74,100 for the Cayenne S, $76,400 for the Cayenne S E-Hybrid and a whopping $113,600 for the top-of-the-line Cayenne Turbo – representing an increase of a few grand for each, before the $995 destination charge.

At the rear of the Cayenne the German maker uses new tail lights designed to give a three-dimensional effect. It also gets new tail pipes as part of a lower rear fascia to make the new model look “fuller” on the road, according to Porsche.

On the inside, the driver now gets a new multifunction sport steering wheel with shift paddles based on the steering wheel of the 918 Spyder. The rear seating system has also been updated to be even more comfortable, and seat ventilation can now be ordered as an option for the rear seats, Porsche notes.

Speed and luxury aren’t inexpensive as pricing starts at $61,700 for the Cayenne Diesel, $74,100 for the Cayenne S, $76,400 for the Cayenne S E-Hybrid and a $113,600 for the top-of-the-line Cayenne Turbo.
