Not zero years but zero freight companies are using small american vans or trucks. They make no economic sense.

As the linked article states dodge sprinters are pretty common these days for new commercial fleets, small or large.

You arguing a completely different argument. We're talking about a worktruck for joe sixpack. No one is suggesting that UPS would be better off with a bunch of F350s out there. Pay attention.

Another thing you're failing to consider syadisti, is that "work trucks" are really only good for a few years with construction type jobs because of the beating they take. A high dollar, long life diesel engine would be a completely foolish purchase considering the rest of the vehicle would never last long enough to make it economical.
So everyone in Europe throws their money away and buys them anyways? I've seen Sprinters used by everything from contractors to freight companies around here. I don't see any reliability reports that confirm your fabrication, so...

Zero? The price difference between them equates to more than 4,600 gallons of gas at $4/gallon. Just because a major freight company drives enough miles to make it worthwhile doesn't mean that the average person can.
Also consider that the Sprinter Syadisti is talking about is not the base model. The base only gets about 21 mpg with no load. God knows what the price difference would be.

Jesus. Buying more expensive cars does not equate to throwing money away.

The point is that spending $15,000+ on a car in order to obtain better fuel efficiency is not going to balance itself out financially.

No it gets low to mid 20s loaded as C&D notes. There are no official dodge or EPA figures since its a commercial vehicle.

Here is some solid information from fleetmag.com rather than BS from BS:

U.S. Is Second-Largest Market for Sprinter

With its 2003 introduction, Dodge Sprinter marked the return of the Dodge brand to the commercial vehicle market. Domestic sales in the U.S. have increased ten fold to 21,961 units in 2006 and the United States now ranks as the world’s second-largest market for Sprinter vans.

Since 2005, Dodge Sprinter sales have exceeded target projections every month with an overall increase of 9 percent in 2006 versus 2005. For Canada, 2006 sales increased 27 percent from 2005.

The all-new Dodge Sprinter offers the segment’s most best-in-class advantages, world-class quality, innovations, design and performance, comfort and safety, and builds on Dodge’s rich commercial heritage, successfully bolstering the company’s position as a competitive player in the commercial vehicle market.

Dodge Sprinter competes in the 2500 and 3500 series large van segments along with Class 3 low-cab-over-engine (LCOE) trucks. Sprinter’s addressable market is identified by 50 percent of all 2500 series vans and 100 percent of all 3500 series vans and Class 3 LCOE trucks. The Sprinter dominates the Class B segment in the recreational vehicle market.

Firmly established in the Class 2-3 commercial van market, the 2008 Dodge Sprinter will appeal to a range of customers in traditional vocations including construction, plumbing, carpentry, flooring, painting, roofing, electrical, heating, ventilation and air-conditioning, as well as a host of niche markets including dry cleaning; contractors and landscaping; delivery operators and passenger transport. Dodge Sprinter has quickly become a preferred vehicle of choice embraced by the market’s major courier companies including FedEx, UPS and DHL.

First off, diesel is a hell of a lot more expensive in europe than it is here, so economically, there is a big difference in why buying more vans might work. Secondly, the truck options for europeans are not as cheap as they are for Americans.
You have been shown in this thread the difference in cost between the two vehicles, since you're a cornell grad, I assume you can work the numbers for yourself too see that it would take many, many years for the sprinter to be economically viable, and I can tell you from personal experience that people in the construction biz don't keep vehicles long enough for that to happen. What more do you want?
And again, the base sprinter here in the US does not get 30 mpg, its more like 21.

No it depends on MY (newer models have the 3L) and it gets low to mid 20s loaded with the 3L:

C&D said:
according to people who use them to earn a living, low-to-mid-20s, fully loaded, can be seen regularly. The last time we tested a Sprinter—it comfortably seated 10—it was fitted with a less powerful but more miserly 2.7-liter diesel inline-five, and we got 30 mpg combined.
The Dodge Ram and Sprinter were both available for the 2003 MY, starting prices were:

2003 Dodge 3500 RAM Van MSRP: $23,265.00

2003 Dodge 3500 Sprinter MSRP: $23,774.00

The van is pricing competitive with commercial vans in the same class. Also a F150 is an entry level truck, not a heavy duty work truck.

Considering the Sprinter was designed when gas prices were $4-5 gallon in Europe, they are making a lot more economic sense and that is why they are more popular these days.

Heavy Duty Trucking - October 2005 said:
However, look where fuel prices have gone. Yes, the big-cubic-inch, 6-liter-class diesels can deliver good fuel economy. But all things considered, smaller displacement equals greater efficiency. That's why today's Dodge boys offer an alternative – the Euro-style Sprinter, manufactured in Dusseldorf, Germany, by Mercedes-Benz and assembled in Gaffney, S.C., for use here. It's designed to sip fuel on a continent where prices have been at the $4- to $5-per-gallon mark for many years, and should save money and make sense here.

Wow, there are some testy people on here ;)


All I know is that I have a 2000 Pathfinder, fully paid off that I use for work, to haul my work trailer, and to take bikes/skis and gear to the mountains. I get 15-18 mpg, but it would make no sense for me to buy another truck or van, and have car payments.

What I am trying to do, is stop using my Pathfinder for daily stuff, and get a scooter. Since Tuesday I have driven almost 60 miles in just BS around town stuff easily done on a scooter. I'm looking at a 200cc (171.*** actually) with 75+mpg. By My calculations, at $3495 and $4/gal, it would take just over 15,000 miles, or just over a year to pay it off, just in gas! Gas is going up, and that doesn't take into account the routine maintenance on the Pathfinder that will be greatly reduced and stretched to a longer time period.

Not sure if this was discussed in Toshi's thread or not but....

Say you own two cars. An SUV and a small car. (say a Civic). You want to replace one of them to save the amount of fuel you burn...your costs etc....

Assume you rack up the same mileage on both cars, and maintenance and all that is about equal.

So now say you either:
Replace your current SUV that gets 12mpg and replace it with one that gets 15 mpg (3 mpg better)

or:

Replace your little car that gets 35 mpg with a super efficient car that gets 50 mpg. (15 mpg better)


Which option gets you further ahead?
answer to your question:

right now you have a 12m/g and a 35m/g, which if you do the same millage:=N on both cars you will get a fuel efficiency of 0.112g/m [gallons per mile]
Option A replaces the 12m/g with a 15m/g SUV which in turn gives you an overall fuel efficiency of 0.0952g/m.
Option B replaces the 35m/g of your actual situation with a 50m/g giving you an overall fuel efficiency of 0.103 g/m.

In other words if N (your millage) is 100miles you'll need the following amounts of gas:
Now: 11.19gallons
Swapping the SUV: 9.52gallons
Getting the super efficient mini car: 10.3 gallons

So seems that getting the more efficient SUV is the way to go.

I know Escalade's are huge with the working class. Nothing says "grocery hauler" like dubs.

At least 90% of SUV's are utterly unnecessary. A family of 4 doesn't need seating for 8. Sorry, your argument doesn't hold water. If you would like, I can photograph the jackasses in my neighborhood to support my point. There is a single guy around the corner with a Suburban lifted a foot high rolling polished 22's. I'm sure he needs 400 cubic feet of cargo room to haul his Costco ramen home.
with regard to cargo volume:

Ford Expedition
146 cu ft

Toyota Sienna 2008 model
147 cu ft

Food for thought

And you can't honestly believe that all of America is comprised of upper-middle class suburbs correct? America is a big place. There's a LOT in the middle there and there's a lot outside of whatever natural sounding two-word suburb you are in...

you must work for a company that doesnt take care of their ****.... i know of a few construction companys that have had the same trucks for 10+ years because of MAINTANCE and taking care of them.. and what are you thinking the 80'S? trucks withing the last 10 years or more have been build CONSIDERABLY well. me i will never own anything but a truck reguardless of if i need it or not... yall have fun in your smart carts, prius, and anything else compact... cause i know that a fullsize truck can hit a juniper tree and the people have a considerably good % of walking away .... little car... not so much.. have fun with your coffins on wheels :D. and im one of those "a-holes" that blow black smoke on small prius' have a good day :)

keep in mind that F-250s on up aren't crash tested (or emissions tested, or tested for mpg by the EPA) because they're over 8500 GVWR, and many years ago regulators thought that no one would be idiotic enough to drive them as passenger vehicles. so in truth you have no idea whether your big truck will be safe.

if your counter is that mass alone makes a car safe then think again: http://bridger.us/2002/12/16/CrashTestingMINICooperVsFordF150/



40 mph. same offset barrier.

Funny you mention that. I recently saw an F250 wrapped around a lightpole at an intersection that couldn't have been more than 30-40mph. The pole went through the dead center of the front of the car. The whole engine block slammed backwards into the cabin. It looked like the driver and passenger would have been ok, but anyone sitting in the middle would have been impaled on the crankshaft of the engine.

Mass makes a huge difference when you think about. Smart cars do so well in crashes because they have so little mass to stop. If you have a heavy vehicle, you need crumple zones to absorb all that energy. With a light car, not so much. The negative G's might be much higher, but that's not what kills you.

now take those 2 same vehicals and insert them into a high traffic dumptruck town and have a dump truck t-bone or rear end one...

Ok. Mini shoots off it a tanget direction because the lower mass allows it to be pushed aside. The F-150, with larger mass produces a larger impact, because there is more inertia pushing it towards the dump truck, or transversely, it wraps around the DT, because there is more impact required to deflect the vehicle.

Some people actually use their vehicles occasionally. Many of us do and need it. Try working somewhere else than behind a desk for once in your life. BTW, no standard gas vehicles with USEABLE cargo space are getting over 20mpg. Learn to read.
Get down off your high horse, I've worked numerous outdoor jobs including a few years in both construction and roofing, and know perfectly well what a worker needs out of a truck. I'm glad you can make ridiculous assumptions about me, though.

If you believe there aren't huge numbers of large vehicles owned and operated by people who would be far better served with a station wagon or a minivan, you are delusional.

Oh I fully believe they are. I know there are lots of people who own them that don't need them and do retarded stuff to them, whether it be out of stupidity/fashion/ego/whatever else. They're manufactured for a purpose that many people seem to assume doesn't even exist. Too often I hear the argument that trucks/SUV's need to be outlawed and hybrids need to be more or less "required", and that there is no reason for full size trucks and SUV's to exist. My point is that is all fine as long as the hybrids are capable. They aren't for anyone who needs a utility vehicle. Short sighted-ness assumes that there are more people using the larger vehicles as a toy or something overkill/wasteful than using them for work or making use of their capabilities. I know there are a lot of people using them for dumb stuff, but I think there are far more who actually NEED them (though I have no figures to back this up with).

I live in the hippie capital of the world, and I have plenty of friends with trucks and vans. Most of them do contracting and they require their full sized vehicles.

I have never heard anyone complain to them or big utilities vehicles ever in SF. They know they shouldn't drive their massive vehicles every time they go to the pump. Most of them have 4 cylinder econocars to save cash.

i just read that it's actually based on a study in science (the magazine, not the term in the abstract, heh). i now defer to the european standards.

now what i don't get is g CO2/km. does it scale linearly with l fuel/100 km or not? if so then why is it reported separately? what's the point?
there's essentially a certain amount of carbon tied up in the gas, a lot of the weight of liquid gas is carbon atoms. when it reacts with two heavier oxygen atoms from the atmosphere there is about 25 lbs CO2 per gallon.

this is an interesting site that shows how much carbon can be saved via a couple of hypothetical changes in behavior or policy.
http://carbonsolutionsne.org/analysis/initiatives/carbon-cycle/new-england-decarbonizer/carbon-solutions-ne-plotter/base_view


this link explains how the carbon savings from the car and light truck sector were calculated:
http://carbonsolutionsne.org/analysis/initiatives/carbon-cycle/new-england-decarbonizer/help/CSNE Data reports - Passenger Cars and light trucks.doc/view

i wrote the report during my last days at the university... they have a whole class now on adding different options. my takeaway from that project is that our vehicle mpg needs to be somewhere near 500. instead we're quibbling about 5mpg increases...

Name ONE person (outside the NBA) that NEEDS an Escalade, or a Lincoln truck when a Silverado, or F150 wouldn't work.

I know, 22's are required for avoiding construction debris.

In England and Europe:



Both have 2.0 - 2.5L engines. NA straight fours or similar most of the time. Can carry enough gear for anything. I guarantee both of these vehicles can carry more **** than a truck.
