If anyone predicted Porsche would be one of many types leading the cost on plug-in hybrids back when Chevrolet launched the Volt in 2010-just as Porsche was debuting its first-ever production hybrid with the Cayenne-that person should be dealing futures on Wall Street. By replacing that SUV with this 2015 Cayenne S E-Hybrid plug-in, Porsche is now offering three plug-ins, much more than some other car manufacturer. Clearly, among those three is a 918 Spyder, which isn’t exactly mainstream production. But still.
To have the Cayenne to plug-in status, Porsche basically grafted inside the Panamera E-Hybrid’s high-voltage battery, electric motor, and power electronics, upping the lithium-ion battery ability to 10.8 kWh from the sedan’s 9.4. Otherwise, the powertrain is identical, on the Audi-sourced supercharged 3.0-liter V-6 for the Aisin eight-speed automatic. Torque is routed to all or any four wheels via a limited-slip center differential with a rear-biased (58-percent) torque distribution.
The remainder of the car is identical to the recently revamped Cayenne, with a few exceptions. The 282-pound battery, containing of 104 individual cells, consumes the area normally available for an additional tire. Versus other Cayennes, the $77,395 E-Hybrid has two additional buttons on its center console. Selecting “E-Charge” prioritizes replenishing a depleted battery so future electric driving is feasible. This increases fuel consumption by about 20 percent, based on Porsche. In “E-Power” mode, though, the Cayenne moves solely around the single electric motor at speeds up to 78 mph. This ability is mostly directed at European markets, where it allows owners to avoid congestion fees in certain cities. Americans are able to utilize this silent-running mode to sneak up on friends or, at the least, valets.
Every time the Cayenne starts, it’s in E-Power mode by default, assuming there's enough juice within the battery. Porsche claims that charging with a 240-volt hookup takes about three-and-a-half hours using the standard 3.6-kW charger; an optional 7.2-kW unit can cut that to 90 minutes if you've got admission to a high-voltage feed.
Driving in a city will make it hard to desire more power compared to electric motor produces. Maximum acceleration with all of 416 gas-and-electric horses should return a zero-to-60-mph sprint well below six seconds, plus a quarter-mile will pass in just over 14 ticks, according to Porsche. No too shabby for the two-and-a-half ton ute.
