My GTS got 20 MPG recently, so why are new cars not much better?

Hello Hell Bronze.
I think it's funny you bought that car. I had my '93 listed at the same time in the porsche magazine and he called me for advice on pricing. The pinstriping pegs his identity. So glad you got rid of that.
Congratulations on the acquisition of a truly beautiful example of the breed.

Wife parked a K2500 Burb and now drives a 928.
Daughter parked a Wrangler and drives a 928.
Two of them get together and brag about their respective excellent gas mileages.
( this is working well for me)

Just sold a 08 Corvette auto that had 436 H.P. with the optional tuned OEM exhaust and I was getting 27 highway. My newly acquired 94 928 GTS has 345 H.P. and gets 19mpg. Thats 8mpg more with the Vette with an additonal 91 H.P. Thats fairly significant. What are 400 H.P.+ 928 with turbos or superchargers getting. Lets compare apples to apples, in this case H.P to H.P.
I'm happy with that.

I average around 16.5 in my GTS will get upwards of 22 on long trips if I don't get on it hard. Unlike my 94 turbo which can get as much as 30 on the highway when off boost but will drop to 6 mpg or less if I am on the gas hard. Usually I average around 12 in the turbo because I can't ever drive that car slow.
As far as the N/A 964 that car will give me a decent 18 mpg average on the street but on track I am lucky to see 11mpg. So how hard you push it makes a huge difference.

I find it interesting that some of the new "small cars" do not get better mileage than they do..... my wife has a 2008 Crown Vic 4.6 ltr V8 that we just finished a 3500 mile jaunt in.....air conditioner on for the whole trip, stop and go as well as a lot of interstate, often 75 mph+/-, average for the entire trip was 26.4 mpg. And the Crown Vic is not a small nor light car.
Well my 93 GTS manual has been fluctuating between 14.5 & 17.3 for most of the time that I've had it, running on 98 octane fuel at $8.24 a gallon (UK gallon is slightly larger than a US gallon). ... And that diesel Jetta sounds like I should check it out.....I was recently in Franch and drove a Volvo 5 cylinder turbo diesel station wagon with 6 speed that did not sound like a diesel, ran like a scalded dog, relatatively speaking, and got some tremendous mileage, over 50mpg if I did the conversions correctly....

Fogey, our 84 auto gets at least 20mpg and the 84 5sd does too.
The 86 measured 21 on long trip to and from SITM.
84 auto started out much lower, but the O2 sensor was bad and the vac line had come off the vac advance.
Check also that damper / regulator isn't leaking gasoline into the vac lines.

I have gotten 29.7 average on a 1200 mile trip in it, and i do not drive easy.
The S4 will get between 13-19 depending on where and how i drive it.

A model T would get 20 mpg and ran on just about anything that would burn. It also lacked the sorts of electrical gremlins present in modern cars.
I get ~15 hwy, 10 city in my 82. I don't drive very hard, and usually cruise 5 to 10 mph below the speed limit on the interstate. Engine is a work in progress though.

Sure, the problem with the pinstripes was that they were painted on, so I could not just "erase" them with one of those wheels like you can with the sticker type stripes. I reseached all kinds of methods but finally saw a guy on Youtube do it with Meguiar's fine-cut cleaner no.2 and a Dremel tool with a little round felt pad. The pinstripe paint on my car was apparently much tougher than the paint in the video because it took much longer to dissolve the stripe, but it did work. The secret is not pressing too hard, just letting the cut cleaner do its thing, an inch at a time. Must have taken me a good 20 hours, and went through a lot of pads and almost the whole bottle of cleaner. Only place that shows a little bit of trauma is on the gas door, for some reason the painted stripes adhered especially strong to that surface. Most people seem to agree that the car is much better now without the stripes!

Beautiful GTS by the way and it definitely looks 100% better without the stripes.

fuel economy is determined by a few simple factors:
Weight
aerodynamics
gearing
engine HP and BSFC
While a GTS did quite good for a supercar of its era...modern supercars are far better....for example friends with 505hp Corvette Z06's (same effective aero as 928) get near 28mpg at lower highway speeds in the super tall 6th gear......my 414hp M3 got as high as about 25.5mpg when driven slow enough (think 60-65)....
