Really? Show me those facts. When I traded in my 2008 f-250 CC 4X4 XLT 5.4L they gave me 27k for it. But then they said they screwed up said they thought it was a diesel but they honored that price. They said they should only gave me 21k for it. So if my truck was a v-10 they might have gave me what another 1k for it. So please explain to me how a gas engine truck has a better resale value then a diesel.

 

Gotta' love Google...

Well, as promised, I got my issue of DIESEL POWER magazine where they did a complete test on gas v10 vs diesel. They tested towing, dyno, acceleration, fuel economy, and cost vs benefit. All topics that are hotly debated on these forums weekly. Here is what the article said:

THE TRUCKS

Both 2008 Ford Superduty 4x4, short box, extended cab, automatic transmissions. The V10 gas powered truck had a 4.30 axle (considered the best for towing/hauling with a V10), and the diesel truck had a 3.73 axle which is not only very common, but the only axle available with the Duramax diesel, and the standard axle with the Cummins since 2003.

THE PRICES

The diesel truck stickered for $51,040, and the V10 powered truck stickered for $45,055. Both were similarly equipped, though not identical. That makes the diesel truck ~$6000 more.

THE WEIGHTS

The diesel truck weighed in at 7710#, the V10 truck weighed in at 7050#.

THE DYNO

The diesel truck is rated at 350hp and 650tq. The V10 is rated at 362hp and 457tq. Dyno tests were conducted on a Mustang Dynomometer.

Diesel truck:
290hp @ 2969 RPM at the rear wheels
516tq @ 2814 RPM at the rear wheels

V10 truck:
223hp @ 4032 RPM at the rear wheels
316tq @ 3458 RPM at the rear wheels

THE MPG

City traffic:
Diesel truck - 18.28 mpg
V10 truck - 8.95 mpg

Highway unloaded (Grapevine pass):
Diesel truck - 19.08 mpg
V10 truck - 11.94 mpg

Highway (Highway #99) and city runaround:
Diesel truck - 19.72 mpg
V10 truck - 9.88 mpg

Highway #99 and Grapevine pass, cruise control:
Diesel truck (had transmission in bed) - 15.74 mpg
V10 truck (no load) - 12.55 mpg

Test average:
Diesel truck (unloaded) - 339 miles/17.62 gallons = 19.27 mpg
Diesel truck (including towing) - 865.9 miles/51.17 gallons = 16.92 mpg
**Diesel average - 1205.5 miles/68.79 gallons = 17.52 mpg
V10 truck (unloaded) 694.6miles/66.97gal = 10.37 mpg

**Note that they did not "tow" or haul a load with the V10, other than the 15-65 mph test (below), but they did with the diesel. They did not include this average of the two figures as I have.

THE TOWING

Load = 8500# (Jeep on 3000# trailer)

15-65mph:
Diesel truck - 22.39 sec avg
V10 truck - 29.71 sec avg

**Note no mpg number for towing with either vehicle

THE DRAGSTRIP

Average of 7 runs:
Diesel - 16.0 sec in the 1/4 mile @ ~83mph
V10 - 17.4 sec in the 1/4 mile @ ~76mph

**Note that both trucks were in 4 high during drag testing, and that they "spooled" the turbos before launch on the diesel. They said that a simple put it to the floor froma standing start drag would have resulted in closer times, but that the diesel would still be faster.

THE PAYOFF

Cost of diesel option over the V10:
$6895 (diesel option) - $600 (V10 option) = $6295 cost for diesel (with fuel at $3.00/gallon, this $6295/3 = 2098.3 gallons of fuel)

12,000 miles per year/10.37 mpg = 1157.2 gallons of gasoline used/year
12,000 miles per year/19.27 mpg = 622.7 gallons of diesel used/year

Diesel = 534.5 less gallons of fuel used per year
2098.3 gallons/534.5 gallons = 3.93 years to break even

WHAT THEY MISSED
The following is my opinion:
- Maintenance costs:
Well, the 6.4L diesel takes 15 quarts of oil, but needs to be changed less often. V10 takes 7 quarts of oil. Both need fuel/oil/air filters and tires, etc. Pretty much a wash there if you ask me.
- Trade in value:
The diesel truck will undoubtedly be worth more with 100,000 miles on it than a V10 truck will.

 

I have a 6.4L and I don't get 18 mpg around in the city. How did they do that?

 

I don't get 18 in the city either, but I'm pushing 19 now on the highway at 65. I'm getting 15-16 in the city though. Shorter lights, and not a BIG city is what I'm guessing. Everyone gets 0.0mpg sitting at a light.

 

And I have a V10 and don't get 9. I get 12 city. The whole test was a joke.
The dyno numbers are way off too. A 2V V10 makes more than that!

I read that test when it first came out, its pure BS.

 

Yeah I'm getting around 13 in the city and a solid 18 mpg on the highway. But my truck is bone stock for now. Plus I only have 1300 miles on it. Can't wait till I do a tuner, CAI, 5 inch delete DPF exhaust system. Probably be getting a spartan tuner. I will make tons of power and will be getting 20 plus mpg. I would love to see a v-10 do that.

 

I don't know the dyno numbers are pretty close to what they are suppose to be. I think a gas engine will lose about 130 hp through a auto tranny. Probably manual tranny will make more power.

 

V10 cost $310 more than a 5.4.
The PSD costs $8000 more than a 5.4.

The V10 adds $1000 over the 5.4 when you sell it.
The PSD adds $6000 over the 5.4 when you sell it.

With the V10 the value gos up, from $310 to $1000.

The PSD on the other hand looses Money. You spend 8k on it and only get 6 back.

The V10 holds its value better.

 

The PSD is 7200.00 more...that's an 800.00 difference, so it's not inconsequential. The V10 is a 600.00 downgrade over a 5.4. Get your prices right.

A similarly equipped (as mine) 2009 V10 books for 27,000
Mine with a 6.4 books for 39,000...That's a 12,000.00 difference.

 

Well, work calls...I'm on-call this weekend and someone wants a new condensing unit...Easy 3000.00 unless I have to change the a-coil or line set....then it'll take a lot longer. Have a wonderful day, all...

 

Ok, $7200.
The V10 AND 4.10 gears is $600. The v10 is $310 over a 5.4 with 4.10s.

 

Those numbers are way off. The 390HP 5.7 Hemi in the new Ram 1500s dynos at over 300RWHP. There is no way a 362HP V10 is going to dyno at 223RWHP, that a loss of 139HP.

The general rule of thumb is 10-15% power train loss, the V10 in that test has a 39% power loss. That kind of loss just isn't possible. Three things could have happened here. 1. The V10 had a problem and wasn't making full power, 2. They lied and tested an older 2v V10, or 3. They lied and didn't test a V10 at all. I've also never heard of a stock 6.4 with the DPF still attached getting anywhere near that mileage either. I have a friend with a 6.4, and whenever he tows a trailer he usually gets around 7-9 MPG, around 13-14 highway unloaded. Add that to the fact the magazine is Diesel Power, I'm sure they are going to obscure the facts as much as possible to make the diesel seem better.

@ ChargersFan: Not sure where your getting bluebook prices from, but I just configured two identical 2008 trucks with 75,000 miles on kbb.org using their suggested retail value option. The truck was a Crew Cab F-350 Lariat 6 ft bed. The 6.4 booked for 34k, the V10 28k. Only $6000 difference. The second truck was CC F-350 Harley Davidson, 8ft bed. The V10 booked at 35k, the 6.4 at 37k. Just $2000 difference. For fun, I just did a basic work truck, 08 F-350 regular cab XL, the 6.4 books at 27k, the V10 at 21k. $6000 difference again.

 

The V10 is a $600.00 downgrade over the 5.4???? Please explain that!


Two similar 2009 trucks and the 6.4l is $12,000.00 more than the V10 - I don't believe it.

I think LeadHead prices are more on par.

 

You say anything is BS if it does not talk great of the the V10 ...why is that

 

First off let me say the MPG & power numbers seem a little messed up to me. I've never heard of a stock 6.4 doing that good on mpg. And i'm a diesel guy saying this about this test.

Second I know my truck could beat that v10's hp like taking a walk in the park. And lets not even look at the torque numbers for the v10's sake.
V10 truck:
223hp @ 4032 RPM at the rear wheels
316tq @ 3458 RPM at the rear wheels
