718 Cayman S real world MPG

[cypriot]

This is a mildly interesting read. The title is a little misleading as the 718 was nowhere near the worst performing car here, (I am looking at you volvo) however, the 981 Cayman S wasn't tested. So, what do people get out of the their 981 cayman Ss just so we can some kind of vague, non-scientific comparison?

25.1 mpg over last 7.5k miles (total 13k).

Mixed driving, not much in way of town/city - PDK.

My PDK 981S has averaged 30.4mpg over the last 5500 miles (previous 4k was similar) but that includes a disproportionate amount of motorway driving (far too much at 50mph), and less sporty driving than I would like (low 20s are more typical driven with verve). Mid to high 30s are easy on long motorway runs going as fast as traffic will allow. Even 100mph cruising on the continent gives 30+ mpg. I would expect a manual 981S to be less economical on motorways - the PDK gearing is higher and the coast function of PDK saves quite a lot too.

Although you haven't asked, but for those interested, my 2014 981 2.7 PDK shows the last 9,999 miles as 36.5 mpg average.

43 mpg is the best I've had on a run.

Not a 981 but a 987.2 S manual. I'm averaging 29.2 mpg over the last 5,000 miles. That's very mixed motoring, city, B roads and motorways. Quite a few short runs too. My best trip was 39.8 mpg.

That's pretty good. My manual is at 28mpg after 9800 miles. First 2000 averaged 22 so 30 is about right after run in.

I'm gonna guess the new S averages aroun 28-30

Pretty much bang on to what my 981 2.7 manual is doing too!

Be interesting to know what the real world MPG of the 2.0 4t 718 is....they usually are 5mpg down on what the figures say.

Pretty much my experience from a Cayman 981S PDK. Just switched to a Cayman GTS PDK and early indications are that consumption is at least the same. Last year did close on 2,000 miles on a European trip including some 90-100 mph cruising in Germany plus a few blasts (up to 167). 34.6 mpg.

Cheers for the responses guys. So it seems real world mpg hasn't really changed from the 987 days! Emissions obviously have, as has power, but its still interesting. Funnily enough, the circa 29mpg that most people seem to be getting is better than my brother's diesel's 3.0l merc... hilarious!

My 2ltr. 718 Boxster bought last month has covered 975 miles and is averaging 32 mpg. Mostly suburban and country B roads.

That's pretty much what I thought it would be! That will probably improve with miles too (my 981 and 987's did).

OT have you got a manual? How are you getting on with the car....with all the doom and gloom from people on here saying it's the end of Porsche as we know it, I had a 24 hour test and thought the 718 2.0 was impressive!!!

My car is PDK. Its the best box I've experienced. Though I can understand people sticking with the 6 speed stick. After 14yrs. with a 6 cylinder Porsche I will miss the Howl. The new sound to me is more of a Growl which has grown on me over the month. As I'm deaf in my left year I guess I only miss the howl half as much as most other people. As for everything else about the 718, the Boxster has made yet another step forward. I just love it.

[undred orse]

you are not trying hard enough Dyffed!I've had 25mpg over 850 miles of mostly b roads and only about 50 miles of motorway over the last few weeks.
Mine is an S with pdk.I think driven on a mix of roads it should do 30 mpg very easily.

As far as the engine is concerned do not go alone by the often harsh criticism you will see on here and elsewhere.The engine does have a character of it's own and while I accept it is not to everyone's taste and never will be it is wholly unfair and wrong in my opinion to equate it with a VW/Audi turbo engine or similar.

Drive it and come to your own conclusion and remember that some critics have cars with the previous engine and will quite naturally be emotionally invested in their cars which can influence an assessment that the new one is not as good.

Isn't that always the way with turbos, save the fuel if you're cruising but burn more when the turbo(s) kick in, bit of a joke for improved fuel consumption.

Gee whizz, that seems pretty poor unless you're doing lots of town driving and/or lots of track driving. I've averaged about 24 in my 987.1 3.4 over 90k miles. It improved from about 22 for the first 30k to about 25 for the next 60k. Fewer track miles and longer runs nowadays. I've seen 31 mpg over 120 miles once...

[Sparkyhd]

I just met a bloke in his 718s at Warwick services and he'd just driven to and from Liverpool and he'd got 39mpg so far.

[FourPotPorsche]

Was he still running it in? If not he should be ashamed of himself

The total joke is that the emissions tests and MPG tests that set the numbers are totally not realistic; they're at low revs and low speed. Massively favours a turbo that cuts in later. Simple physics; all being equal if you want to generate the same amount of power you'll need to convert the same, or thereabouts, amount of fuel.

I (really hopefully) don't see this continuing; soon EU etc will change to closer to real world conditions for emissions and mpg testing, this should hopefully put an end to the 458 (official UK quoted MPG 20.6) to 488 (official UK quoted MPG 24.8) turbo'ing syndrome. And yes in the real world 'upgrading' 458 to 488 owners are seeing similar consumption for similar driving styles between cars (it's all about range).

I did 380 miles yesterday in my 718 S Manual, averaged 63mph and got 28.9 mpg according to the trip computer. Mostly reasonably clear dual carriageway A roads (A303 / A38 to West Country and back)
I wasn't trying to be economic (or not). Car still on fairly low miles and this is about 5mpg better than I normally get on mixed urban driving
