2011 Ford Super Duty 6.2-Litre V-8 Gas Engine article
The 2011 Super Duty is sporting an efficient 6.2L dual equal V8. Sounds cool; sounds like Ford is taking its trucks into a good place for the future. What do you guys think? Do you think the power will be there? Are you impressed by all of the innovations under the hood and in the cab?
I hope they can tune it for more torque. Torque is more important on the Super Duty trucks than horsepower.
Awww, man! Not this again!
Torque and horsepower go hand in hand, there is no one without the other. High torque at a certain RPM means high horsepower at that RPM.
What's important in a truck motor is a consistent torque curve throughout the RPM range; preferably one that has a strong low end and increases as the engine revs.
Horsepower is a measure of torque at speed. Torque without RPMs is useless, as it makes 0 horsepower. A mythical 1,000,000 ft-lb engine spinning at 1 RPM makes 190 HP. A 4.0L V6 out of a Ranger will pull harder than that 1,000,000 ft-lbs.
I think the 6.2 could be really great. I'm excited to see what the new VCT system can do for an engine that large. I've heard it will be more efficient than the outgoing 5.4L V8, and with over 400 ft-lbs and HP it should be an amazing engine. Far superior to the GM and Dodge gasoline HD offerings!
Since I only buy F450/550 C/C's it is good for me. I need the torque more than horsepower, because I use them as tow trucks. I don't want to spin the engine to 6000 RPM to merge on the highway. While I think the 6.2 is a great engine, it is not a great replacement for the fat torque curve of the v10. Hopefully they come out with the 7 liter version, that would be a suitable replacement for the V10 on the cab chassis.
I agree, a nice, flat torque curve is what we need to have. But just because it has a high peak torque number doesn't say anything about low end torque, that's kind of what I was getting at.
For example, it could generate 455 ft-lbs @ 5,000 RPMs, and it would be a lousy truck motor if it had half that at low RPMs! 455 @ 1500 would be amazing.
High low end torque numbers mean it has high low end horsepower, since they do go hand in hand. A high peak power output normally means it has lots of torque at high RPMs.
For example, a great motor would be something like 410 HP @ 5,000 RPM and 455 ft-lbs @2,000 RPMs. Such a motor would be pounding out 430 ft-lbs at 5,000 RPMs, with peak torque at 2,000, which would provide a nice, flat torque curve all the way up to redline.
Such a motor, IMHO would be much better than the current 3V V10.
