[718]

Pleasantly surprised by the return on two long drives today in my 718 2.0 PDK. First from Birmingham to Leeds and then from Leeds to London. Wasn’t particularly trying to be efficient, roads were just too busy to have proper fun. I just used light throttle inputs to stop the PDK dropping from 7th to 6th. (Although I did get to open her properly on a couple of occasions ?)

Since passing the 5k miles mark I’ve noticed the PDK is happy to hold 7th down to 50 mph where it would previously only engage 7th after 60-65 mph.

Appreciate we don’t buy these cars for MPG but curious to hear what others people’s experiences/expectations are.

Very impressive we loved the MPG on our 718. My wife and I were quite surprised at the fuel efficiency and I in no way drove my CS sedately.

On longer trips we have seen low to mid-30's for mpg in our 2.0 Cayman w/PDK. Can't complain about that!

I've been driving gently while running in.
My last two refills worked out at 34.5 mpg and 36.7 mpg.
That was letting the fuel drop to under 2 gals and then filling to brim each time.
Now that i'm driving harder i don't expect to see 30+ ever again, not that it matters - i bought the car to enjoy its acceleration and handling.

 

[Gtipirelli]

On a long motorway journey at 80mph I always see over 40mpg

Shorter and country journeys are normally in the very low 30s

That from a Cayman S with 12k miles on the clock

It is the perfect little sports car. Thanks for sharing your experiences.

I don't know if Porsche has also implemented different units, but normally it is important not to compare UK MPG and US MPG as 30 UK MPG is roughly 25 US MPG due to the difference in a UK gallon and a US gallon.



As for fuel economy, on a 45 km drive on Sunday I averaged 13.3 km/l or 31.28 US MPG or 37.57 UK MPG, which is my current record.
But I have not had the car for long so fuel economy has not been a priority yet.

 

[RussellHodgson]

My best was about 31 mpg (US) driving about 50 mph for about and hour and a half.


My usual is around 20-24 mpg.

 

[DriveInHouston]

Word of caution: When the Brits talk about mpg they are talking about Imperial gallons. These are about 20% larger than our US gallons! So, when they quote 35-37 mpg, don't have a stroke...

The best I've done, on Norm Mode, 7th gear and Cruise Control was 34 mpg US.

Normal highway driving on Sport gets me 26-28

It's old, but this thread has a lot of feedback on fuel economy from those who have had 718s for a while now.

Bottom line: The 718 is a phenomenally efficient vehicle, even by general standards (much less by fast-as-spit sports car standards).

I entered “Mpg” in the search but came back with no results.

I posted the same pics on Cayman Boxster UK Facebook page. A handful of 981 drivers responded quoting similar mpg figures which tbh had me stumped. If the 981 drivers are seeing 38-40 MPG then there doesn’t seem that much benefit in downsizing. I imagine they’re quoting UK gallons as it’s a UK page. Genuinely stumped my this. Would appreciate others the opinions of others on here about this.

The economy is roughly the same 718<->981. The increased power and torque is "free".

Last weekend did a trip of about 250 km at an average speed of 110 km/h. My 2.0 PDK did 16.5 km/l (which is 38.81 US MPG). I must say I am very happy with that.

From my own experience, switching from a 981 to a 982/718 made absolutely no difference to economy whatsoever. But if you have narrow winding roads, with multiple hairpin bends & short straights, the 982/718 with its greatly improved low down torque is not only a far easier & more relaxed way to cover ground quickly over the model it replaced, but generally considerably quicker overall.

 

[Gtipirelli]

I travelled from Leicester to Heathrow this morning so covered about 100 miles. Took my time due to heavy traffic and roadworks and the trip showed 47 mpg at journey end. Absolutely amazing but pretty boring

Wow, I'd have to cover a quarter of the journey on the back of a break down lorry to achieve 47mpg & I'd rather not.

 

[MLJJ]

Base, still enduring run in period, sport mode mostly, and back roads (less than cruising speed) getting mid-20's. Not really looking at that statistic too much because of what the car was intended to do.

Both valid points. More power and better performance for the “same” fuel is definitely a win. Plus the amazing drone ❤
