With the 2015 Porsche Cayenne S E-Hybrid being the latest kid on the plug-in hybrid block, we figured now’s the time to present its details EPA ratings.

As noted in the EPA-supplied spreadsheet, the Cayenne S E-Hybrid, unlike the Panamera S E-Hybrid, gets an actual all-electric range rating that’s never zero.  While the PHEV Panamera has an AER of 0 to 15 miles, the Cayenne plug-in is rated at 14 miles.

Additionally, the Cayenne gets a combined 27 PHEV Composite MPG rating.

Some additional Cayenne S E-Hybrid specs/info includes:

  • Price: $76,400
  • U.S. On-Sale Date: November 1, 2014 (will be available nationwide)
  • Battery: 10.8 kWh lithium-ion
  • 0 to 60 MPH: 5.4 seconds

The ability to recharge the battery fully from the ICE (losing only 20% ICE mpg) makes this very attractive. Panamera E-Hybrid owner reported 700 miles on one tank of gas for freeway driving.

30 gallons fuel tank?

Porsche web site (usa) says 21.1 Gal fuel tank.

From website –

My best miles to gas pump range-
I have had the 2014 eHybrid for a while but thought what’s the best I can do before I take it back to the gas pump. Starting with a full tank of gas and using all electric between trips, grid-charging, e-Charge mode on highways and mixed mode driving over a month or so, the best I got was 842 miles when the gas light turned on.

I am sure there is enough reserve in there for me to do another 100 miles or so. I filled the tank to full with 18.4 gallons giving me an approx mpg(e) of 45.7.

Not bad at all considering it wasn’t all driving like a grandma.

So obviously way to short electric range since there is no problem getting over 1000 miles a tank on a regular diesel car.

I feel bad for them. There are plenty of smaller VW/Audi/Porsche batteries @33 NEDC, or ~22 miles. 14 EPA miles breaks the standard “2/3rds” we apply to NEDC, to predict where EPA will land. We would not only have been wrong, to predict 22 miles here. 14miles/10.8kwh, or 1.3 miles per kwh, is one of the lowest efficiencies, yet. It says this car would have to get upwards of 30kwh on board, to reach Volt like range.

Well, I’m sure it’s around a 5000lb AWD vehicle, so it should be much less efficient than a FWD Volt, but immensely more roomy.

the car is not really that inefficient its just that the audi/porsche/vw group decided to only use about 60% of the battery for longevity.

at almost 4k pounds, Volt uses 65% and achieves 2.3 mp kwh, not 1.3. it’s also 5 year old tech.

60% of 10kwh = 6kwh

14miles / 6kwh = 2.3 miles / kwh

ok, your math:
65% of 16.5kwh=10.8kwh

38miles _/ 10.7 = 3.5 miles / kwh Volt

either way, lots of substitutes!

…i don’t mean to be an efficiency hawk. it’s how one might shop for more storage when the number is so low. at 1.3, or 2.3, it makes daily need ~30kwh, where NHTSA “80% of drivers go 40, or less miles per day.,”

I’ve said this for some time, but the Cayenne PHEV is no Tesla X killer.

I’m not sure who this will be aimed at.
Its electrification specs are pretty bad. 14 mile AER? Meh.

It is slower at 0-60 than an ICE cayenne.
The PHEV gets 25/28 mpg while the ICE version gets 20/27 mpg. Not impressive
Looks about a $5,000 premium to an ICE Cayenne

Overall I think it will compete with BMW’s X5 e-drive and Volvo XC90 PHEV, but all three will disappoint and none will make a dent into X sales unless Tesla has more delays.

The one way these could sell is if they cannibalize their ICE counterpart sales.

But I dont see many buyers in this segment paying more for less function and so minimal green credentials.
Then again they may enjoy the Lexus affect, where many people bought the first fewhybrid Lexus SUVs despite only minimal gas savings. People just saw the word hybrid and bought

I agree that the Cayenne SE will not put a dent in Tesla X demand, but it will find a market.

The Panamera SE has an almost 10% take rate, when compared to the regular Panamera. I would put the upper bound of the Cayenne SE sales at around the same level.

For a stay at home parent, that takes several short trips a day, the short all electric range could be a good fit. It will all come down to whether the all electric driving feel is desirable to the potential buyer.

Josh, I agree with you. I wouldn’t be surprised if this is a modest success by cannibalizing similar ICE offerings, but I can also see weak demand given its relatively lower performance at a higher price.

Many of my friends are in this segment. And they just go to the Porsche dealer and go “ooh! Pretty! And you say it’s good for the earth too?”

That’s what I was referring to with my Lexus affect comment above. I had a lot of friends put down big bucks on the RX hybrid even though it barely beat the regular mileage.

It’s ironic that the people most likely to buy such a vehicle are the least likely to care about fuel costs.

At roughly 700 miles range with on-board battery charging its a nice vehicle for many people that don’t want the hassle of charging the Model X – like me.

A trip up to the slopes to ski requires a mandatory stop (for me) at a Supercharging station on a Thur/Fri night and on the return trip on Sunday. Much as I try I can’t make the projected range of the Model X (or S) work for me (https://evtripplanner.com).

I don’t want to be stopping with the family in the car on a trip to or from skiing – the traffic is bad enough without adding additional time. And I feel the Supercharging stations will be fairly full with people waiting in line on those popular evenings – at least that’s my guess here in Northern CA when heading up to the Sierras.

So a 35mpg Cayenne-E fits the bill for me. Nicely loaded it’s about $92K – less than what I project the Model X will cost. Now if Volvo would please release their XC90 plug-in details.

Uh… 35 mpg?

The chart above says 25 mpg and 28 mpg
The ICE version gets 20 mpg and 27 mpg.

I agree that the cayenne would be a great product if it got 35 mpg.

If your stat is true the Cayenne becomes more compelling, and will sell well against Luxury ICE SUVs.

Otherwise it’s underwhelming

I have 1,100 miles on my ’15 Cayenne SEH. My average mpg over that mileage is 32.7 right now. I charge every night and sometimes at an occasional customer site during meetings.

Nearly 2x the mpg of my previous Range Rover Sport. 1 disclaimer..I am however driving it easy so far (no sport+ mode blasts). Overall, very happy.

If I didnt drive to maximize the efficiency (which seems to be my goal now for some reason…kinda like getting a high score on a video game or something), I would probably be at 27mpg average…which is still great.

also – my EV range seems to be 16 normally. The system will run the battery (10.8KW) down to 20% before kicking on the ICE on its own. Then it saves that 20% for extended stop/start activity. There is regeneration during driving (coasting, braking, etc) which obviously extends that a few miles further.
