2020 Cayenne E- Hybrid - Page 2 - Porsche General - PistonHeads UK

Does anyone own a Cayenne E-Hybrid? I've owned a 2020 since new but really struggling with mpg....to the point I've booked the car in to be checked over. I seem to be getting an average ~16mpg when in petrol mode and yomping through the petrol. Is this normal with other owners? Cheers

I had one for a couple of years, did a couple of long runs to the SoF and only got 23 -24 mpg so I guess 16 around town may be about right.

I can believe that given the extra weight of the batteries etc. I looked at buying one but decided unless you either got tax breaks or had a commute you do on 100% electricity it didn’t make sense from en ecological or financial perspective.

Gareth135R - You plug it in regularly.... correct? ;-)

I've had my share of Porsche Plug in Hybrids both Cayennes and Panameras all bought due to favourable tax concessions. Take these perks out of the equation then they really gobble fuel on any long journey as the ICE engine is underpowered when the batteries are exhausted. We used ours mostly for 30-40 mile commutes where over 50% was in electric mode. We were religious in topping up the batteries when they were parked up at home otherwise our petrol bill would be ridiculous. The longer the journey especially motorways, the less efficient they became. We also owned a few diesel Cayennes which were much better suited to the Cayennes weight. Taycans make much more sense to us as each and every mile costs the same from the first to the last. Would never buy another Hybrid unless it had an electric only range of at least 50 miles. We had a new gen Cayenne Hybrid as a courtesy car when we took our Taycan in for some software updates last year and I was shocked on thirsty it was on the long motorway haul back home as the battery was pretty much exhausted.

Interesting Topic..... I have a Cayenne V6 Hybrid Plat Edition for Sep del was hoping that it would see 30 MPG on a long runs as planning to use it over in Spain mostly. I drove one at PEC last month on road and the short track IMO PDCC and RWS is a must have for these heavy Hybrid cars, the one i drove was the later one with the bigger battts that came in for Oct 20 if i recall correct in hybrid mode this did 35 Mpg whist driven down the A34 to the M40 and back to PEC, no idea what it would be like when the Batts are dead. It showed a reg gen rate from the ICE of just under 7 ICE miles to get one E Miles at 70 MPH. My Current car is V6S Coupe just checked this has averaged 22 MPG over the past 9k miles, my last 2016 4.2d Cayenne did 25Mpg over the same distance . Would love a Tycan X over but have not had a good experience with remote charging with the loan cars i have tried, as in the chargers dont work or had to wait to long to use it. Cayenne GT arrives next week but wont be thinking about MPG, Lol Edited by APOLO1 on Friday 18th March 10:13

Agree with Taffy I wouldn't buy a Hybrid unless it had an electric only range of 50 miles.

When the e range is exhausted the Cayenne Hybrid gobbles fuel at an astronomical range. Ours averaged about 30mpg during our entire tenure however his is based on mostly 30 miles average journey times. Long motorway journeys are very thirsty in them.

I have a Turbo S e-hybrid. Can’t say I look at the mpg very often - on a run can get high 20’s, tootling around town likely in the teens. If you never get better than 16 then something doesn’t sound right. Don’t know how you drive obviously - they are (can be!) stupid quick for a heavy car!

To be honest i never tested the stand alone E range if it does 30 miles that would cover about 80% of its use for daily basis. The V6s alone without the Hybrid part are not very good on MPGs so i can see what you mean.

My Turbo GT is doing about 23-24 mpg on a decent run, actually about the same as the hybrid with a discharged battery. Only covered about 1k miles at the moment so still very tight.

Terrible. Mostly drive with a full battery but it's obsolete once you get a move on

Just checked the App - says 23.5mpg in 12.5k miles and 25mpg since last fill. Feather Feet.

Just for perspective, my Cayenne 2.9 S has managed a lifetime average of 27mpg over 22k miles. A recent round trip to the alps gave just over 30mpg, cruising at 130-140kph. It’s getting better as it loosens up.

Porsche, please bring back the diesel!

I’ve had my Cayenne Coupe Hybrid for 20 months. My commute to the office is only 7 miles each way so most of the time the car’s in electric mode. Fill up around 800 miles and the average consumption is showing as 43.5mpg With no charge in - does low 20’s Does me well overall - great car! Graham

Harry’s Garage (YouTube) did a long term review on the BMW 4x4 hybrid. Think it has a larger cap battery. It worked well for him, no good if you don’t like BMW I know but proves as some have said here they can work with right journey profile. We must also remember that running on e power in residential areas does contribute to cleaner air.

I have 2019 Cayenne hybrid and living in surburbia 95% of my journeys are electric only. Easily enough go to keep up with urban traffic. My experience on long journeys is that overall consumption is not dissimilar to my previous Cayenne S at mid to high 20s depending upon your cruising speed on the motorway. If you are going to push it the battery soon runs out and consumption will rocket given that it has less power then the S and more weight but overall it works well for my mix of driving.

Bloody hell, what are you lot doing with yours?? I've got a V8 hybrid and, ok flat battery on a short journey it might be mid teens, but even lead footed motorway runs on a flat battery I'd struggle to get it below 20mpg, and I'm averaging about 23mpg with a lot of long journeys. If I'm off the motorways for a couple of weeks I'll usually get around 30mpg on a tank. All in with my motorway heavy miles it's ended up about the same as my old V8 diesel, albeit with a smaller outright range. In comparison I used to get about the same average fuel consumption from my lighter, smaller, less powerful F-Pace SVR

I got a bit better yesterday 26/27 on a 150 mw drive, but try and keep the boost psi at zero so the cylinder de activation kicks in. The car is is so fast, may i enquire what Tyre PSIs you run at ? the chart on the car says 38/41 Cold, i find this to high and it bounces, 33/36 feels about right but can not get the low pressure warning light to go out?

This is the classic use case for the hybrids - to bring (much) better economy for short trips. They're not designed to help with better long distance economy.
