The 2015 Porsche Cayenne S E-Hybrid may have undergone a facelift from previous models, but it is what you don’t see that is making the difference in this year’s edition. This is a plug-in hybrid crossover that is onion-like in its layers.

From the simple to the sublime, the Cayenne S E-Hybrid propels the brand’s green cars to the next level. We’ll start with the pressure point on the accelerator for controlling the electric and combustion modes. The combustion engine starts when the pedal is pushed past its activation point, or otherwise as necessary. It is powered by a 3.0-liter V6 supercharged engine that provides 333 horsepower and a 95-hp synchronous electric motor, delivering a total of 416 HP. With a top speed of 151 mph, this hybrid can get from zero to 60 in 5.4 seconds. Its generous 10.8-kWh lithium-ion battery is said to deliver an all-electric range of just over 20 miles at speeds approaching 80 miles per hour. You may have to be reminded you are driving an SUV/Crossover.

The power plant works in harmony with the Cayenne S 8 Speed Tiptronic transmission, which not only decreases fuel consumption but increases the vehicle’s comfort and agility. The transmission uses lower engine speeds in higher gears which reduces the noise level inside this Cayenne. It also actually adapts to your driving style, shifting gears automatically. New for 2015, is the extended automatic start/stop function, which not only stops the engine when the vehicle stops, but also as the vehicle is stopping.

The Cayenne S E-Hybrid employs use of what the company calls its Porsche Traction Management (PTM). According to the Porsche website; “PTM is comprised of an active all-wheel drive system with an electronically variable, map-controlled multi-plate clutch, automatic brake differential (ABD) and anti-slip regulation (ASR).” More simply put, the hybrid has a permanent all-wheel drive system with self-locking center differential. This differential sends power to the axle with the most traction. It also provides more precise steering.

Unique to the Cayenne S E-Hybrid are the E Power and E Charge buttons. The E Power button switches to full EV power, while the E Charge button fires up the combustion engine with the electric motor serving as a generator to charge the battery. It can be amusing to switch between modes, monitoring fuel consumption on the infotainment system as you do so.

Inside, the raised center console reminds you of Porsche’s racing genealogy. This puts the vehicle’s controls close to the multi-function steering column in convenient and comfortable fashion. The dashboard has an almost throw-back appearance with its straight line design. Of course, every detail has been considered in the well-appointed interior. Like the Cayenne S, the E-Hybrid comes with almost countless amenities like a high-gloss monochrome black interior package, automatic tailgate, 2-Zone climate control, 18” wheels, Tire Pressure Monitoring, and an anti-theft alarm system with ultrasonic interior surveillance and immobilizer. The car’s fuel efficiency is proclaimed with the green e-Hybrid nameplate. The vehicle comes with a base price of $76,400 and has a four-year, 50,000 mile warranty.

In spite of the fact that this E-Hybrid packs an extra 600 lbs. when compared with the Cayenne S, this Porsche responds nimbly to the driver’s commands. It is powerful, responsive and fun to drive. It clearly is designed to handle its weight well. Perhaps best of all, it offers the versatility of a crossover with the efficiencies of a hybrid along with the prestigious nameplate of Porsche.
