Hows the fuel consumption 997.1TT vs 996TT vs 997.2 TT?

Does keeping it stock tuned have better consumption or will it improve it? MY 996tt is not stock and not very good on gas. 10l-11l/100 km but you can't hit boost otherwise it sucks gas up like a pig, unsure if the tune has anything to do with it and a stock 996 Turbo would be better but I can't use my current one for a DD anyways since it's manual and the wife can only drive auto.

Thinking of replacing a 14l-19l/100 km gas guzzler with automatic 997.1 Turbo. Thinking the 997 awd is much better for winter then the 996 but it still has the mezger engine so is bulletproof and cold weather driving won't be an issue that the new engine seems to have getting scored cylinders when running in cold climates and I am unsure about the DFI sludge over long term to place a bet on a new engine design and then have to replace in 10 years. The other option is a much cheaper 996 Turbo (tip) completely stock. Though don't really want to have two of the same thing in the garage and the 997 has quite a bit more HP stock and a lot newer so thinking fuel consumption would be better. I do about 30k km on it a year and keep my cars for a very long time.

If you're driving daily in traffic expect similar results. I get on average 17l/100km. Open road it sits around 10-13, if pushing it or driving slowly it jumps up quite a bit. In a 997.1.

I do about mostly 90% open roads not pushing it. Sounds like 10-13 is worse then my 996tt

Over the summer I averaged ~ 14l/100km. This was 60% highway and 40% city. I always drive around campus at work to have the car warmed up so that I can go WOT merging on to the highway. I usually do about 2-3 full boost runs in 2nd and 3rd gear each way to work. In the city I always get on the boost in 2nd during city driving.

Jumper5836,
I had a 996TT/MT for 6 years (new in '01 - '07) and when I switched to 997TT/Tip in '07 (new in '07 - now) I noticed about a 10% improvement in Fuel consumption...nothing scientific...I am in the 20's in my 997TT/Tip.

Not sure if I answered your question...and by the way, I bought the 997TT as TIP because I was using it as my DD in heavy traffic.

How large is the fuel tank? Can't find a manual for the 997.1 Turbo

This reminds of some old Aston Martin ads:

"If you have to ask the price, you probably can't afford it"

"If you have to ask about the gas mileage, you definitely can't afford it"

LOL. I have a modified 07 trubo and I get around 16 MPG (I rarely drive it easy).

+1. I don't track my spending on my Porsches because I don't want to know

Granted, I've not been in a family situation where I could DD one of my P-cars, instead they've always been a toy. So, gas mileage may make a difference there at some point.

This is from the owner's manual:

Fuel tank approx. 17.7 U.S. gallons / 67 liters including approx. 3.17 U.S. gallons / 12 litres reserve

My toy doesn't get driven easy as seen in the picture above think works out to 7mpg, but on a DD commute of aprox 100km at 5am in the morning sipping on a coffee or tea with the wife working in the next seat, driven hard is not gona be in the equation. Got to mention this will be a DD and not a toy which I all ready have one that with track mods done doesn't make it a very comfortable DD.

I figure I am spending at least 11000 a year of fuel alone now. And dropping from avg 15l to 11l over the year saves money that could go to the insurance differential between two and is a bargaining point with the wife towards switching it.

67l tank vs 996 of 63l is also a good thing means I have more range and may get more trips in before having to refill.

Who in there right mind drives a Turbo Porsche and gives a care about Fuel Economy.

Unless of course you are convincing the wife of your wise choice to go from the 996 to the 997 to save money if so I completely understand.

lol yea, I've never even looked to see what it was nor do I care. But if it's gonna be daily driver for him It's probably important.

Wouldn't the DFI be the most miserly of the bunch?

xbox_fan

The DFI engine will be much better than the mezger on gas.

I get 17-19l/100km on my 997.1tt but that's running E85 through ID1000's
