Hi all,

This might be a stupid question, I just collected my brand new macan s today, I took it on a few short city drive for totally 8 miles, the range is down from 430 to 359 miles. The app shows the average mpg 10.8, this sounds crazy. I did left the car running without driving for about 1 hour to set things up and playing music, but still 10.8 mpg sounds too much, right?

Any idea?

You should get 15-20 mpg on a good day

You are obviously using it properly. It is a Porsche

The V6's take about 10 miles to warm up. I regularly see well under 20 mpg in the first 5 miles but on long runs get more than 30 mpg. 33 driving from Scotland to the South Coast last week

What you describe is never going to produce any meaningful mpg data. Use it normally for a month or two and you’ll see hugely more than 10.8 mpg. 👍

Your engine is new, tight and not run in yet....so friction loads will be higher. BUT leaving it running for an hour (and presumably not overheating?) means the cooling system (fan, water pump etc) were working really hard.

Were the 8 miles at low speeds? This would all explain the very low mpg.

With this V6 engine it's best to drive it at non town speeds to get the engine temp up to 90C. Then you will see mid to high 20s mpg.

Bottom line.... sub 20mpg on short low speed runs. Possible to get low 30s mpg on a long steady journey once the engine is fully run in. ;)

Ignore the MFD readings and enjoy the car.

What you see on the MFD will probably be very optimistic

If MPG is important you bought the wrong marque.

The Multi Function Display (MFD) also has an mpg readout which seems to have a minimum disposable value of 12mpg so maybe the app is more accurate than that! I've done nigh on 20k miles in my current S and averaged 24.85 mpg so rest assured in "normal" use it will be better. Enjoy!
