One of the main challenges of any electric hybrid car is getting a commendable range from the battery. Porsche announced some good news recently: The Cayenne E-Hybrid is about to get a larger battery pack, which will extend its range considerably. First launched in 2019, the Cayenne E-Hybrid offers a luxury SUV E-hybrid to the Porsche line-up. With good fuel economy, an athletic chassis, and quick performance, the Cayenne E-Hybrid is about to be an even more attractive buy.
A Demanding Powertrain
The Cayenne E-Hybrid powertrain is one that requires a solid battery setup. The standard Cayenne E-Hybrid boasts a 3.0-liter turbo-charged V-6 engine, as well as an electric motor. These are mated to an 8-speed automatic gearbox that manages to push out a very respectable 455 horsepower. The Turbo S E-Hybrid gains a more powerful 4.0-liter twin-turbocharged V-8, which adds an additional 215 horsepower to bring the total figure to a whopping 670hp! The Turbo S E-Hybrid now boasts the quickest acceleration in the Cayenne lineup.
These figures are impressive when comparing the E-Hybrid to the likes of the Cayenne S Coupe, a non-hybrid variant, which only musters 434 horsepower. The E-Hybrid power is a major reason that Porsche is releasing a range-extending battery.
Porsche’s upgraded battery will substantially increase the E-Hybrid’s all-electric range. It takes the current battery capacity of 14.1kwh all the way up to 17.9kwh. Porsche claims that this will result in an additional 30% of all-electric range. Tested on the European Worldwide Harmonized Light Vehicles Test Procedure (WLTP), Porsche’s claims seem to be promising. If proven true, this means that the electronic-only range will increase from 19 miles to a maximum of 27 miles. This will allow for longer trips with less charging stops required. Another benefit of this increased range is that Cayenne E-Hybrid owners will be entitled to an E numberplate, as well as a reduced company car tax amount in Germany.
Driving Mode Tweaks
Porsche has also tweaked the Cayenne’s driving modes when it comes to the Sport Chrono package. Standard on all E-Hybrids, the E-Charge mode means that the engine will aim for an 80% recharge instead of 100%. This is because charging slows down once the battery pack reaches 80% capacity. This charging strategy helps to prolong the life of the battery pack, and also allows for better fuel efficiency. This isn’t to say that higher power levels can’t be achieved. For instance, in certain situations, the Turbo S E-Hybrid can charge up to 12 kW per hour when in Sport+ mode.
The Porsche Mobile Charger Connect system enables plug-in hybrids, such as the Cayenne, to charge at a speed of up to 7.2 kW per hour. Drivers are then able to set a timer, or a charging target, which allows targets to be linked to a specified location. The charging solution from Porsche gives the driver various charging solutions, including benefits such as pre-set climate control.
A Pricey Offering From Porsche
Porsche seems to be moving in the right direction with its range-extending improvements. Only time will tell, however, if Porsche’s claims will be proven correct once the new Cayenne E-Hybrid goes on sale in 2021. What it does do is make the Cayenne E-Hybrid range more attractive to potential customers who will benefit from fewer charging stops and the E-Charge mode. The standard E-Hybrid is expected to be an easier sell as it comes in at around half the price of the Turbo S variant. At $163,200, the Turbo S does seem a little bit pricey, but only time will tell if it manages to be a strong seller or not.
