Just got my first 911 a few months back - an used 4S with about 50k miles on it. Still has the factory warranty and the price was good so i went for it. There is one main thing that bugs me (for the others i found answers here). The fuel economy seems way of - and i'm just concerned there might be something off with the engine.
around the city i get on average 25 l/100KM - about 9.4mpg (US) - driving it moderate - just in nomal mode - if i go into sport it's about 30-32l/100km. - 7.3 mpg (US)
on highway - the lowest i got with a cruising speed of 130km/h (80mph) is 11.5l/100km - 20.5 mpg (US)
Is this similar to what ur getting? Just wanted to check before going to the dealership with it.
80% Sport and 20% Normal, Manual mode shifting on PDK with 50% highway and 50% city with a lot of redline runs and I average 17mpg. Highway only 25-30mpg.
9mpg or less with just moderate driving is absurdly low.
I have a 2023 Carrera T and I averaged 8.7 mpg in a 3 day on track high performance driving school at Watkins Glen going no slower than 40 mph. On the hwy I'm good for 28.3 @ 80 mph.
That's pretty awful. Most of my driving is my commute to work on surface streets, with lots of stop lights and sitting around. On my commute, even in sport mode (thus with auto-start-stop disabled) and with the M-Engineering tune (which cut my mileage a good bit), I still get 11-15mpg. On highways without the tune I saw up to 31, and with the tune it's still 26-28.
Definitely low. C2S here, so maybe fewer drivetrain losses, but I'm low 22's on average. Mid-teens when I'm on it, pushing 30 mpg highway cruising.
You've got a lot of miles on your ride. When was the last time someone looked at the air filter and spark plugs?
Maybe stop towing your camping trailer with it?
Wasn't able to get under 20mpg on highway over a 35mile trip even at a constant speed of 65mph 😅
Had it checked about 1 month ago and did the oil change and air filter at the dealership - spar plugs they said are still good and everything is fine with the car...

You don't happen to have a teenage driver in the household siphoning off fuel from your car, do you?
