Hi All,

A long time lurker on the forum and looking for some advice.

I've been driving BMWs for the past 10 years with my last one being an X6 40d E71 (2012).

I'm considering a 2019+ Cayenne as I fancy a change from BMWs and don't fancy the issues with a Range Rover.

I'll be looking for one with as many options as possible (PASM/14-16 Way Seats and ideally Sport Design Kit etc.) but wanted people's opinions on the different engine variants.

I've always had diesels and probably would've gone for another but understand they stopped doing diesel in the Cayennes from 2018.

How is the economy in the 3.0 V6 and the Twin Turbo 2.9T? Has anyone experienced the E70/E71 BMWs for a direct comparison?

Am I right to disregard the e-Hybrid as I did read that they are very juicy when not running on the Hybrid Battery due to the weight of the battery's?

Had a 2023 Cayenne S for a week., think it’s possibly the 2.9tt?

Sounded great, lovely exhaust note.

Reasonably quick, pretty fast for a 4x4, needs revs though, not as torquey as a diesel.

Very nimble handling for a 4x4, nice and tight, great steering, super sharp.

Utterly horrendous on fuel though, 18mpg average over a variety of driving.

I absolutely couldn’t live with that level of thirst. The problem with poor fuel economy is it might not be your biggest running cost, but it’s so in your face day in day out it’s hard to ignore. Literally pouring money down the drain.

A more boring choice, but Id recommend a G05 X5 or G06 X6 30d or 40d, 80% of the dynamics, but 35mpg under same circumstances.

I'd also agree with that last suggestion....sadly.
I chose a F15 X5 4.0d over a 2nd gen Cayenne 3.0d 7 years ago, because the engine in the BMW was much better, but with a view of the next change of car being to a V8 diesel Cayenne......

Frustratingly, that option was removed by Porsche when the dropped the V8 diesel (and all diesels) after VWdieselgate, and my try out last year of a Gen III V6 petrol Cayenne, was uninspiring. The petrol engines just don't suit a large 4x4 SUV like the Cayenne, which is crying out for a big torquey diesel (as is the fuel gauge!)

The X5 is my default due to how well rounded it is, but a bit bored with it now. Owned E70 30d, F15 40d, Q7 50TDI then current G05 40d. That 3.0 diesel BMW is mighty and the perfect match for a large SUV.

The Cayenne just screams out for the Audi 3.0 bi tdi they use in some A7’s, SQ5, S4 and S5, think it’s around 350bhp, frustrating they don’t do it, as it’s readily available and would be an easy parts bin special. It would be a fantastic combination, take my money now!

Having had half a dozen Cayennes, since the first Gen 4.5 V8, 4.8V8 through to several 3.0diesels, I have recently changed to the V6 eHybrid, only because the diesel is no longer made. A deal on the run out Platinum edition made it worthwhile.

Pleasantly surprised how effective it is. We drive down to Spain in it so range is important, but also local running around works well with the hybrid. Not the quickest but perfectly acceptable and reasonable economy if you factor in the hybrid. 25mpg when running without battery.

Extra weight over the diesel is well disguised but noticeable when pressing on compared with the previous model.

Worth a look.

I’ve had a 2.9 twin turbo S since April 2018 - it was one of the first of the generation to be delivered. Average economy over 38k miles has been 27mpg. It loosened up and improved a lot past 10k miles, and now does 32mpg on a long motorway trip, as long as you keep under 80mph indicated. Around town it averages low 20s, never as low as 18mpg, but then it’s the family bus - we have other cars doing most of the fun driving. It even did 25mpg with a roof box fitted and 4 bikes on the back driving to the French alps.

I’d echo the comments on the 2.9 engine’s character. It has plenty of power and torque, but likes revs more than I expected. I think it would be better suited in lighter cars like the RS4, whereas the Cayenne feels a bit heavy for a revvy V6. Having said that, when you do rev it there is no shortage of pace on tap. The way the car carries speed on poor roads, with air suspension and rear axle steering, is superb compared to most SUVs, and the brakes are wonderful even stopping 2 tonnes.

In terms of driving experience there really isn’t that much difference between the different generations of Cayenne. I own a 2017 S Deisel which we’ve done a lot of miles in, have driven several newer Cayenne’s including having a loan car of the latest version a couple of weeks ago. The V8 diesel in mine is a better engine that in all the later cars…monumental torque, sounds pretty good and will get comfortably in to the low mid 30’s at motorway speeds. Newer cars have marginally better ride and bigger screens etc but I don’t think the interior quality is as good and the 18 way seats in mine are much more comfortable than the equivalent in the newer cars.

Came from an E70 SD which I ran from new (I tend to buy a well specced car for a family car and get my money’s worth smile ) Cayenne is a noticeable step up whichever one you choose.

Thanks for the replies.

I think I'll have to drive the variants to see.

Only reason why I discounted the older shape (2016-2017) is just the inside feels a bit more dated to compare the newer shape although the 4.2 Diesel would be ideal.

Although saying that, I'm noticing petrol is 10p cheaper than diesel!

There was a time for quite a while last year, that petrol was running about 20-25p less than diesel....!!

I guess it is dated but if you get a later car...I think after Sep '16 they have Apple Car Play. Petrol is 10p cheaper but in % terms the diesel mpg still works and the power delivery just suits the car so much better.

Its the latter that is the biggest thing......big capacity and efficient diesel just suits this type of vehicle more than a petrol....even more so if towing on a regular basis.

So I am looking into this too, trying to decide between the hybrid and standard. Essentially the .1 of the latest variant will do 25 miles on the battery. So if I had a commute of 200 miles, and a drive I can charge from before I leave and free charging at work. Would 50 miles of cheap power make the Hybrid with it for the other 150 miles it will be out of juice.
