What is your best fuel consumption per passenger?

[RustyLugNut]

But with an extra seat added between the two front captain chairs and a person seated over the wheel well hump.

So, 17 people X 21 mpg @ 55 mph = 357 person mpg.

The roof rack held most of the passenger luggage so aero was shot to hell.

The gross vehicular weight was over 10,000 pounds.

The Spicer rear axle held 5.56 gears spun by a 727 auto transmission and the whole thing was powered by a 360 cu. in. engine.

The engine was heavily modified. But, the 55 mph speed limit of the time was the real key. Los Angeles to New Orleans and back. The fuel mileage averaged out to 21 mpg.

My best was not in my own car, but in a rented gen 3 Prius: 65.4MPG (over 3 days in California) X 4 people = 261.6 person mpg.

I got 239.2 mpgpp with my 1997 Chrysler Town and Country minivan. 29.9 mpg average on the trip with 8 people total.

I have a friend who has achieved 306 mpgpp with his 18 passenger Ford van.

I'll bet the new Transit diesel van will deliver some impressive mpgpp with all seats occupied.

Just last week: 30.0 mpg over 2,000 miles in the Odyssey (epa 16/23), with 6 passengers = 180.

[niky]

Just last night, but highway only, 73.5 mpg (Accent Diesel, 45 mph, just off-idle in 6th most of the way, then 5th gear in-town)

Four passengers, 293 mpg-p

Maybe use mpg per ton like they judge trains by.

I dont know how on gods green earth you got 21mpg out of that. My parents had a '93 15 passenger witht the 360 2bbl tb injection and if it got better that 15 you considered yourself lucky. It was the family vehicle and also the youth group hauler. Lasted forever though, over 250,000 miles, only trouble was keeping transmissions in it while driving through the mountains whith every seat filled and pulling a uhaul trailer of equipment.

My car will do 28mpg x 3 people = 84 pmpg

It was an early form of the Chrysler "lean-burn" engines. At cruise, it ran at 18:1 AFR. Your later van had the closed loop 3 way catalyst and so could not run such a set up. The intake consisted of a CARB legal Holley spread bore as a replacement for the Carter Thermoquad sitting atop an Edelbrock SP2P manifold. An Accel ignition fired the fuel mixture. BlackJack headers cleaned out the exhaust into an oversized catalytic converter ( two way ). An Edelbrock "mileage cam" produced less overlap and more effective cylinder pressure. The EGR valve was blocked off and replaced by a full time digital water injection ( 7 gallons water used for every 40 gallons of gasoline ).

An early digital fuel economy readout ( fuel flow meter and driveshaft sensor ) along with the good old vacuum gauge helped the driver stay in the sweet spot for mileage gains. As already mentioned, the 55 mph national speed limit was still in effect and that was the maximum speed for most of the trip. 65 PSI was the tire pressure.

This particular van came equipped with a "heavy duty towing package" that included a larger radiator and transmission cooler. At just over 200,000 miles, both the engine and transmission were still doing fine until emissions caught up to the modified set up and the vehicle was parked behind the shop where it still resides.

Trip yesterday: my vx, 156 miles/ 2.2 gallons with 5 people (3 kids, but they're people) = 354.5 mpg/pp

I usually don't carry people, but I did a bit of it this past week.
Driving to GGP, 300 miles with two people had 46.99 mpg, giving me 93.98.
Driving on GGP, 49.42 mpg with two people was 98.84 mpg.
Finally, the rally course 36.76 mpg with three people landed us 110.28 mpg.
