This car on Ebay says this. Is this possible?

Probably BS but these cars get great milage on the freeway. I'm amazed how long it takes me to burn through gas. Especially the way I drive....

 

Funny you should mention this. Just talking about gas mileage this evening. My old C4 got incredible MPG and always amazed me how long I could go between fill-ups. My replacement C2 tip however appears to be drinking gas like there is no tomorrow. I don't know what the actual mpg is but I am getting a tad concerned...

 

I don't buy that at all. At 80 mph cruise I get maybe 23-24mpg but that is a far cry from the claim. With the extra frictional losses of the C4 I believe it even less. It is a bunch of crap when people embelish in an attempt to dupe the rest of us.

 

Total BS I might be able to get 25 mpg out of my 91/c2 if I keep the car at 65 MPH and no big revs between gears and keep it on the freeway any thing over that it averages 19-23 mpg with normal spirited driving.

 

On 110 leaded maybe? Or maybe he was behind the slipstream of a truck going downhill?

Kidding aside, the 964 has the lowest drag coefficient (Cd) of any Porsche ever built, so who knows...

I certainly can't achieve those numbers. My car's a binge drinker when it comes to gas.

 

I call bs. I have never seen higher than about 25, and I used the cruise for almost a full tank to get that. I love ebay. His car must have the flux capicitor hooked up differently that I do

 

Er, I'm skeptical of this. What I had heard, was that it has the best Cd of the street-going air-cooled Porsches. In other words, it has a better Cd than the 993. I have to believe the 997 blows it away in Cd today...

 

Charlie, that's the number I have in my head from Paul Frere's book. I have the next to last edition of the book (includes the 996, but not the 997).

Although better in the front, I think the wide hips and tires really hurt modern 911's in regard to Cd, but I'm not a pro at this.

 

Total BS. Especially with those "lightweight" US gallons!

Don't forget that there is a difference between a US gallon and an Imperial gallon.
1 US gallon = 3.785412 litres
1 UK gallon = 4.54609 litres

You might get 35mpg (UK Gallons) on cruise at 80kilometers per hour with a bit of slipstreaming on a good day but Miles - I doubt it. I do accept that cruise does do great things if you are happy to sit in the queue on the freeway.

I certainly don't get 35mpg UK or US!! Maybe I just don't want to try that hard....

 

..... the 964 has the lowest drag coefficient (Cd) of any Porsche ever built, so who knows...

Is this true? More than the newer 996s / 997s? Hard to believe...

 

What is the size of a C4 fuel tank (in UK gallons)? If I'm doing all motorway at 80mph, I get about 390 miles from a tank - no idea what that works out as.

 

My C2 has a 70 ltr tank = 15.4 gal. I think C4 are the same.
About 25mpg UK?

 

uh - huh... 35 mpg

am reminded of Jon Lovitz's SNL character, Pathological Liar.

(Somewhere in that sales pitch is my wife... Morgan Fairchild!... yeah -- That's the ticket!)

 

Actually, I might believe him. I do a good bit of highway driving between here (NC) and Georgia with round trips of around 660 miles. I noticed a HUGE gain in mpg after I lowered the car 1.5 in. I also have a K&N filter in it and our cars do gain the most of airflow of anydrop in K&N. Around the city (mind that I kick it into 5th pretty often) I get about 25 mpg but on the highway at 75 mph I get 34 mpg. I've done the calculation quite a few times because I didn't think i could go 600 miles between fill ups.

My 2 cents
