Just in case you’re having a déjà vu moment, rest assured that you previously read an article on this site about Porsche E-Hybrid battery improvements, but at that time we were covering Panamera variants and now it’s all about the electrified Cayenne.
Like last year, both the regular Cayenne crossover SUV and the sportier looking Cayenne Coupe will receive Porsche’s E-Hybrid and Turbo S E-Hybrid power units, but new for 2021 are battery cells that are better optimized and improve on energy density, thus allowing a 27-percent increase in output and nearly 30 percent greater EV range.
The new battery, up from 14.1 kWh to 17.9, expands the Cayenne E-Hybrid’s range from about 22 or 23 km between charges to almost 30 km, which will force fewer trips to the gas station when using their plug-in Porsches for daily commutes. Likewise, the heftier Cayenne Turbo S E-Hybrid gets an EV range bump up from approximately 19 or 20 km to 24 or 25 km.
Added to this, Porsche has reworked how these Cayenne plug-ins utilize their internal combustion engines (ICE) when charging the battery. The battery now tops off at 80 percent instead of 100, which in fact saves fuel while reducing emissions. Say what? While this might initially seem counterintuitive, it all comes down to the E-Hybrid’s various kinetic energy harvesting systems, like regenerative braking, that aren’t put to use if the battery reaches a 100-percent fill. Cap off the charge at 80 percent and these systems are always in use, and therefore do their part in increasing efficiency.
Additionally, the larger 17.9 kWh battery can charge quicker in Sport and Sport Plus performance modes and default or Eco modes, making sure the drive system always has ample boost when a driver wants to maximize acceleration or pass a slower vehicle.
Net horsepower and combined torque remain the same as last year’s Cayenne plug-in hybrid models despite the bigger battery, with the 2021 Cayenne E-Hybrid retaining its 455 net horsepower and 516 lb-ft of torque rating, and both Cayenne Turbo S E-Hybrid body styles pushing out a sensational 670 net horsepower along with 663 lb-ft of twist.
Standard Cayenne E-Hybrid models can sprint from zero to 100 km/h in just 5.0 seconds when equipped with the Sport Chrono Package, before maxing out at a terminal velocity of 253 km/h, while the Sport Chrono Package equipped Cayenne E-Hybrid Coupe requires an additional 0.1-second to achieve the same top speed. Alternatively, both regular and coupe Cayenne Turbo S E-Hybrid body styles catapult from standstill to 100 km/h in an identical 3.8 seconds, with the duo also topping out at 295 km/h.
The 2021 Cayenne E-Hybrid starts at $93,800 plus freight and fees, while the Cayenne E-Hybrid Coupe is available from $100,400. After that, the Turbo S E-Hybrid can be had from $185,600, and lastly the Turbo S E-Hybrid Coupe starts at $191,200. You can order the new electrified Cayenne models now, with first deliveries expected by spring.
