If someone said you can drive 446 miles on one tank, in a GT4, I would have said you’re nuts. Drove from LA to Phoenix, one shot, averaging 28.5 mpg, insane.

 

Did you mean mpg?

If so, that’s awesome.

 

Great! I’m easily getting 26+ MPG on mine on the highway. So far 21-ish around town. I’m at 750 miles so far.

We owned a base 992 for a short time and I took a highway trip. It got over 30 mpg at 80-85mph cruising speed, and the range on the tank when I filled up was something like 660 miles. Mind blowing! And I always disable *** so cylinder deactivation doesn’t take place. All 6 are firing.

 

, more throttle. Seat piston rings.

 

How much gas did it take at fill up. That's the true test, the gauge in the dash is often up to 10% high, at least in my 981 experience.

 

impressive! cylinder deactivation helps a lot. did it get really hot inside the car?

 

Well, I actually drove it all the way to a dealer to swap my cars for their GT4. I thought for sure, I would have to stop for gas, but car just kept on going and going and so I said lets see if I can make it all the way to the dealer in Chandler AZ. Once I got there, I gave them the keys, so no clue how much it took to fill up, LOL

 

I really don't hear the drone, so ya, never turned off the ***, so yes, I think it does help a lot on freeway cruising. And no, not hot inside at all, had temp set to 70 and whole way.
