What is the mpg of a Cayenne, let's say a 958. Suppose you drive with a light foot vs a heavy foot?

Edit : just saw above post. They don't really get 10 mpg do they? Surely with a light foot you can get substantially better mileage than that!? What's the mpg at a steady 70 mph highway?

Hell my old '96 Range Rover LWB got 15 mpg in town. My F250 460 X-cab 4x4 got 10-12 mpg - carrying a freaking camper.

Any experience with either the diesel or the hybrid?

I was looking for a used Cayenne but ended up with a 2011 VW Touareg TDI and love it.
I've only checked the fuel mileage once since we bought it in May and it was 27 MPG.
I expect the Cayenne diesel would be similar.

According to EPA numbers, the diesel gets pretty decent mileage, (better than the hybrid), the hybrid gets disappointing numbers and the gas models are all about the same. The surprising thing is that the V-6 BARELY gets better mileage than the V-8 turbo. This is for the later Cayennes, which I am focused on now.

Here are the numbers:

With a light foot, 955 Cayenne TT can get 15-17mpg on the freeway during extended cruising. Mix any city in that and the mileage quickly plummets. My 10mpg figure is mostly city and spirited driving. The direct injected 957s were a couple mpg better, and the lighter 958s a few more. So a 958 TT might see 20ish on the highway with a light foot. Non-turbo and V6s were better.

The diesels are easily 10 - 15mpg better - - mid 20s to 30ish. I don't know them as well, but they have a strong following. They were subject to Dieselgate and have an extended engine warranty which is a plus. But they also have some carbon deposit issues which are an extra maintenance item.

This post scares me a little. I'm looking at out-of-warrantee 2012-13 turbos and I can handles the expensive tires and brake pads but eating transfer cases and HPFPs might be a deal breaker. I appreciate you sharing your direct experience, thanks.

Then this one makes me want one again. The tuned 958 w exhaust sounds like a fun DD. As for the early ones, I could never own a 10mpg vehicle unless it was an amazing muscle car or a Ferrari or similar, not a DD. You have to remember that we pay close to double the price for fuel here as opposed to the rest of the country. It would cost an absolute fortune to run an older Cayenne in CA. between normal wear items and fuel, not to mention repairs. :eek:

The newer ones I could rationalize because it would do absolutely everything in one car; fun DD, tow trailers, ski vehicle, 22 mpg road trips carrying everything I own, etc...

2012 958. V6 loaded. 80k miles. Older VW V6 cast iron design. No issues really

I do a lot of preventive maintenance. Going good. Would love to put 200k miles and report back
Very happy with it.

Does absolutely everything. Including towing to the track. Towing package is awesome. Changes gearing and timing. Full torque at 2500 rpm. You don't even know you hauling a trailer.

Drive it on the beach. Goes skiing

23mpg cruise control
16mpg summer towing
17mpg in town

Don't need or miss turbo power. I'm not a red light drag racer. Speed limit is still 65.
Don't need air suspension. It doesn't age well here with the salt.

Any large heavy vehicle with a gas engine will have a hard time with MPG . My wife's 2010 Volvo XC90 weighs about 4500 pounds so similar to a Cayenne . Ours is a 3.2 straight six and the best we have achieved on the highway has been 20.6 per the on board computer . And it is a front wheel drive not all wheel .

I think a Cayenne diesel would be a sweet rig but they are much harder to find .

My '04 TT had the fuel pump fail as well. Really not too unreasonable to happen once in 170k miles. All one has to do is pull the fuse for that pump and the car will switch to the second one...so no need to get stuck by the road. One should replace both while you are in there (downright malpractice for a wrench not to do so)...as the second one will probably fail soon after and you already are working in the same area under the back seat (one on either side of the hump). It is not a difficult DIY project. I paid an indy wrench to do mine...but he screwed it up a bit and I had to fix it myself (redo install) but it did not require additional parts. The fuel tank is like a saddle over the driveshaft hump and has a pump for each side.

I think I get about 14-16 MPG. It doesn't seem to care if I am towing a 911 on a trailer at 80mph or tooling around town. Maintenance is about the same as with any vehicle...it is just harder to find someone else to do it right for a reasonable price. I was initially scared to work on it....but now, treat it like the rest of the herd (once I broke down and bought a durametric to read/reset codes). I only get someone else to do the things I don't want to do. I just did the brakes myself and while the parts were massive (and not cheap)...the effort was not unreasonable. Straight forward once you have the unusual tools. I am weak on preventative maintenance...do not change the oil as often as I should, etc...but the car looks and drives like new at 16 years old 170K Mi. I bought it well optioned/used at just under 50k miles at much less than half original sticker price, so I really cannot complain.

It does use a lot of tires, but it is a heavy vehicle for the soft compound tires that most of us use. It is probably not that different from an similar sized performance vehicle.

Gas is commonly $3.50 here and has been over $4.00 in the last several years. I sold the Range Rover when gas was $4.00 and got a Prius, and boy that was a good thing. The only way I could own a 10-15 mpg vehicle is if it were hardly ever driven.

I pay from about $2.04 to 2.10 a gallon for regular and 30 cents more for the midgrade I run in my TT. I use a Cayenne as a daily driver...but the taxes and insurance are so low (and no payments) that I would need to get 100 mpg to replace it. Plus, I use it to tow (when things are too big to go inside the cargo area with the seats down)...so I would need another car/truck for those duties. I have also used it to pull stumps...it has a lot of utility

i have a 08 turbo i purchased with 114k on the clock in 2017. I now have 165k on the clock and three sets of michelin pilot sport a/s3 tire sets! no other major problems, oil changes every 10k. no lights and works outstanding, just eats tires (295/35/21) ugg

The later plug-in hybrid Cayenne is the model I'd consider, maybe. 14 miles electric range means it would be running on battery for half or more of our daily usage, if we plugged it in every time it is in the driveway. I would probably remember to do that. My wife probably wouldn't. So for me, the plug-in hybrid wouldn't be terribly expensive to run - until our gas is $5+ which is probably going to happen in the next few years.

But the later models haven't depreciated enough to make them interesting.

Our 05 Turbo got around 14mpg around town, did far better on the highway. Our 2011 gets around 18mpg around down but is considerably more efficient on the highway. But, if you bury your foot into on the highway the difference is less.

Did two identical drives a couple of summers ago one week apart. Here to the interior of the Province over high mountain passes. First drive had wife with me and my two racing bicycles on the back of the truck. Never really got into the boost much, drove about 125kmh once in the mountains. Sipped fuel. Fast forward a week and it is just me that needs to get back up with my bikes for some racing. I leave late but still need to arrive on time for a group dinner. I get behind a Z06 vette and an M3 once we get in the hills. Figure they can find the radar for me. We average about 165kmh in the mountains. I'm in the boost a fair bit :). I don't have the exact numbers but the first trip was 3:40. Second trip was around sub 3:05. But I burned approx an extra 1/3-2/5 of a tank....

Just curious in your opinion why is it such a tire eater ? Is it just the raw power ? Or performance alignment ? Too soft a tire compound ? If I understand your statement in 51k you have gone through 3 sets of tires , that seems excessive to me . But maybe not .

I’m not trying to scare you away with my Cayenne experience. I still love it and can’t think of anything I’d rather have. I would try to buy a CPO if possible so any issues are sorted out before it becomes a DIY vehicle. If not CPO then make sure it’s priced accordingly. I found that Porsche dealers had the best used deals anyway. It seems like other dealers think they’re worth more than they are.

Rennlist seems to have the best Cayenne forum so you can research there.

Thanks for the data points, they are valuable. I went by my local dealer, (Beverly Hills Porsche), yesterday to check out a used 2012 Cayenne turbo they have. I drove it and was not at all impressed but two things; A) it was not a great example and B) a drive around Westwood, even on a Sunday, never really shows off a Porsche in its best light.

When I jumped in it, the dash display was reading, "Chassis Failure" and the ride height would not adjust from its lowest setting. Maybe just a minor issue, maybe not but not a harbinger of great things in a complicated, feature laden used luxury car. The salesman let me drive it anyway and in hindsight, he probably should not have. The ride was truly awful, not merely too firm but it bounced over any undulation in the road like it had no shocks. Some malfunction of the air suspension, I guess, because they could never have sold one of these new if that was the normal ride.

It was powerful but not particularly responsive or fun in any way. It reminded me of a Bentley I've put some miles on, another powerful, heavy turbo vehicle that is not fun. I was expecting a rocket and it was a dog until you sunk your foot into it, at which time it displayed its massive lungs and would probably pull forever. Just like the Bentley. I want to say that there was something wrong w it but there were no CELs displayed, just the chassis warning.

It reminded me that I've driven one other modern Cayenne, a test drive of a new 2014 or '15 a few years back at the dealer when I was helping a lady friend buy a new car. That one was a V-8 S model and in city driving, it did absolutely nothing for me. I realize that it's an SUV and this time it was driving around the USC neighborhood, (DTLA Porsche), but old man Porsche always said that a great car should be fun to drive around the block. He meant that you do not have to take a 911 to the track or even drive fast to appreciate it, that it was enjoyable at all times. We left the dealership and continued on to other makes of cars.

All that said, I still haven't given up on them. In the lot where the turbo was, they had a slightly scratched-up black Cayenne diesel the really intrigued me. I sat in it and it was less complicated but still plenty luxurious enough w leather, heated seats, etc. It turned out that it was a dealer car that they used as a shuttle, parts runner, etc. Low miles, (41k). I made a cash offer for it on the spot that was plenty fair and he called the boss right in front of me but alas, it was not for sale. That is the model that has my interest at the moment; 400+ lbs. of torque @ 1700 rpm and ~30 mpg highway sounds like a love affair. I'm hunting the classifieds. :)

They are a a complicated, feature laden used luxury car. The driving response is adaptive, and will (when fully functional) move modes between pedestrian Toyota and psychopath Porsche, depending on use.

On gas mileage. I can easily get over 20mpg on the highway, but hoovering around 55mph is a bore. I've been surprised with how long brakes and tires last. Both are huge, I suppose.

Which year and model are you driving these days?

It's all about vehicle weight, power and driving style. If you drive a 5500lb, 500hp vehicle hard in a city setting, 10-15k miles of tire life is not surprising or particularly poor. Long, gentle highway cruising will likely extend tire by 3x or more.

The factory alignment on the Cayenne is very mild - - almost no toe, and only moderate camber (~.5 degrees negative). With correct pressure, alignment and good bushings, tire wear is very even. Hard cornering (especially with braking/acceleration) will not surprisingly accelerate outside wear of the front tires, but overall wear is very even.
