Okay here it is folks. A place where you can argue the attributes of each engine. Let it fly but keep it civil.

I'm going to sticky this thread so it remains at the top of the page and easy to find for now.


NOTE: This thread will not involve any 6.2 vs. Diesel arguments or debates. It's solely intended to argue the strong and/or weak points of gas engines.

 

Uh oh, here we go..........

Obviously, I'm biased because I currently own a 2011 6.2, but I have owned a V10 (2v) before. The both are great engines but the ablilities of the 6.2 are just being tapped into.

Personally, I think the 6.2 is the way of the future in many applications, where as the V10 will only remain in the medium duty applications.

If the 6.2 hadnt come out in the F250, or F350 I would have gladly purchased a V10.

 

Getting out of my '01 V-10 With Auto Tranny (my First Auto) I have to say the 6.2 W/ the new 6 speed tranny "feels like" a better setup...

My v-10 was a great truck with no real issues for about 165k miles - I hope the 6.2 delivers the same....

'01 Repairs
Oil Changes/ Tune ups

@ 120K rebuilt tranny

about 145K fuel delivery prob.. replaced pump - turned out to be inertia switch problem - Same symptom 1 month later..

150K - replace driveline U-joits/ Carrier bearing - Actually only rear u-joint bad but replace all while it was apart..

Maybe 1 bad battery

Hell of a truck - no V-10 issues -except #5 COP went bad at about 50K

 

The 2 valve V10 did not flow air very freely, and had quite a bit less power than the 3 Valve V10's. I had one of each, with another 3 Valve on order. Comparing the 3 Valve:

The SD 6.2 reaches it's max HP of 385 @ 5500 RPM.
The 3V V10 reaches it's max HP of 362 @ 4750 RPM.

23 HP more, but at 750 more RPM. 6.5% more HP @ but 15% more RPM to get it, Pretty much a toss up.

The 6.2 (using the F250 rating) reaches its max TQ of 405 @ 4500 RPM
The 3V V10 Reaches it's max TQ of 457 @ 3250 RPM The 3V V10 has 90% of it's torque available by only 1600 RPM (more than the 6.2 puts out at any RPM)


That's 52 TQ more, at 1250 RPM less, or about 38% less rpm to achieve 13% more TQ.
Clearly a V10 win.

That adds up to the V10 having a way more usable power range. Overall win in power goes to the the 3V V10. The 6.2 will get about 10% better fuel economy.

I'm not saying the 6.2 is weak, only that the 3V V10 is better in power for those actually working them. Unloaded, the 6.2 should be just as quick because of the 6 speed auto trans (The V10 still only comes with a 5 speed auto) The 3V V10 will tow better.

 

Great thread...

Love the V10 in any form....

Power side
6.2L with the new 6 speed is equal to the 3v V10 with a 5 speed in my view. Mate the new 6speed behind the 3v V10 game over V10 wins..

Economy side
6.2L wins.

 

Put this together back in September. Stock runs ... lots a variables here but fun to look at .... best i could gather up..

 

6.2 may be able to hang with the 3V V10 driving around empty, It won't be able to tow like the 3V V10. That is where you need torque, and where the 6.2 will fall short.

 

Here's how well the 6.2 towed 10,000# up a 16% hill:
Three-Quarter-Ton Gas Trucks Towing 10,000-Pound Trailer




If any test turned our opinion around about Ford’s 6.2-liter V-8, it was the 16 percent grade. We haven’t embraced it like Ford’s old 6.8-liter V-10 because we didn’t think it lived up to that engine’s legacy -- until we put it on this hill.
The 6.2-liter V-8 ran up the hill a full 5 seconds and almost 5 mph faster than its next closest competitor, the Silverado. Its rpm seemed to pick up faster than the Hemi’s or the Vortec’s, and it was so fast that it shifted into second gear during one run, though it lost about 1,000 rpm and immediately downshifted. During the other sprints, the F-250 remained exclusively in first gear to top of the hill approaching near redline. The whole run the F-250 howled like a muscle car, not a three-quarter-ton truck with a combined weight of more than 17,000 pounds.






Here's how well the V10 towed 10,500# up a 15% hill:

I can't explain why in one test 250 meters is 820 feet on in another test 250 meters is 1,312 feet (1,320 feet is a quarter mile) but these results still prove to be informative.

Yes, the 6.2 has the added advantage of that new 6 speed auto with it's lower first gear ratio but it is what it is. Ford sold the V10s with 5 spd autos then and Ford sells the 6.2s with 6 spd autos now.

I hope that's not a 3v in the chart in post #8.

 

I'm pretty sure it is.

You'll note that the Ford was actually an 08 while the other 2 were 07s.

In a drag race off a stop the 6.2 will win because of gearing. At a steady 60 MPH or higher, game over the 6.2 will not tow like a V10. The 6.2 no longer has any gearing advantage when traveling at sustained highway speeds. Which is where most people towing loads REALLY need it.

 

LSChicago

I know that you tow daily & Know your stuff.. But I gotta gooseneck/skid steer various attachments that I tow around on Texas highways (interstates & state highways & Farm to market roads) as well as off road. The Jd328 weighs like 8600#, most attachments 750 -950# except my cedar saw which weighs 1200#. My trailer base is 4600# plus 100gal diesel tank/ Full sized gas air compressor misc tools/ spares/chains/boomers/extra ramps. The point is loads are usually maxing out the trailer/truck & the 6.2 pulls very well without a lot of gear hunting. We have commented on this before because my '01 v-10 was the 2v...

I never drove the newer v-10 but the 6.2/6speed is a heck of a setup. My history is v-10 & 460s and the 6.2 doesn't lack anything compared to my past trucks..

Nothing scientific here - just using the truck & it performs well...

 

Yes it is. Only 3V V10's came in the 08 SD's.

 

Great points, but it seems that you're comparing the current application 6.2 with the V10 which is not a good comparision. F450, F550, and up trucks are geared completely different with the 5 speed tranny, were designed to be a towing beasts. The 6.2 is designed for fuel economy, towing, normal driving and a little stop and go play.

Take the V10 in the F250, F350 models of 08-10 and compare it to the 6.2 and that would be a better comparision. I think the 6.2 will take the V10's lunch in all categories.

 

If the 6.2 was better at towing heavy loads, they would not keep the V10 in the 450/550/ and F53 Motor home chassis. I'm still curious what Ford will build when they do replace the V10 in the medium duty trucks. I'm sure it won't be the 6.2, probably a 7 liter version.
