4.6 vs 3.7

How goes the comparison of the 4.6 vs the 3.7? I am thinking about a '10 with the 4.6 but wondering if I should wait and get the 3.7. I am not that concerned abut getting the extra 2 mpg with the 3.7. I just want something that accelerates at a good pace. I don't really want to spend the exxtra $1000 for the 5.0. This truck is for around town trips going to work and to Lowes, etc. For fun driving I'll continue to use my '10 Mustang GT.

The 3.7 will out accelerate a 4.6 2v, but probably not a 4.6 3v. For your use, anything would probably be fine - if you can find a stripped out 2010 at a good price, no reason not to get it.

I like my 4.6 3v. With that said the 3.7 supposed to have simlar HP numbers. My suggestion would be if your going to use it like what you said it would probably be more than fine. But you can probably get a better deal on a 10 today than and 11 for the next several months.

i think it would be dumb to pick an n/a 3.7L V6 over a 4.6 3v

Why? Are you one of those people who just HAS to have a V-8 exhaust sound? Have you DRIVEN both yet?

I see - you are just one of those V-6 haters. That's fine, to each their own.

How does it perform compared to the 3v 4.6? Seeing how he isnt real concerned about the mpg difference i recommend the proven 4.6. I bet its also cheaper than a 2011 truck.

Nothin wrong with a v6. I'm an ecoboost fan. not really a fan of the gay name though. also i think the old big block v6s are pretty cool too

I remember the old I-6 engines, what 'dogs', like the 170 Special in the '64 Falcon that I learned to drive on. I am certain the new 3.7 will be superior especially since it is in the Mustangs. I just get paranoid thinking about 6 cylinder engines. I noticed the peak hp is at 6500 rpm and the peak torque is at 4000 rpm. Just wondering what the hp is like at the 2500 rpm range which is where I be driving most of the time. BTW are there are hp and torque curves available on these engines?

Here is more info on the 3.7 with torque curve

Does the 3.7 come with the 6-speed automatic? That would weigh my decision making process somewhat.

I have not driven a truck with this motor as it is not in the model I am looking at. But I was at a dealership last week on the day they received their first batch of '11s. All of the salesmen that were there were impressed with this motor. They had a regular cab and a supercrew with it and everyone that drove it said the 3.7 would stomp the current 4.6 if the two were to line up. I have seen the numbers where it will dust a 5.3L chevy when they are in equal trucks. It is by far the best base motor in a full size truck on the market.

You're going to be far happier with the 4.6 than the 3.7. The 4.6 has 8 pulses per power cycle versus the 3.7 6 cycles of power or impulses, however you want to say it. If you have driven any of the diesels, compare the smoothness of the Ford V8 as compared to the Cummins I-6. The 3.7 is a fairly new technology engine especially since they have to oil quench the pistons to keep them from burning up. I might be wrong but I think Ford reached a little too far with this engine. I know, they've run a million miles miles in their testing. The REAL test is when folks start buying them and are subjected to REAL world drive cycles without a mechanic looking at it every other day. If you want a 2011, the 5.0 is best engine option.

the n/a 3.7 will dust a 5.3 chevy?


edit : i just realized the EB is a 3.5 and the other is a 3.7. i was thinking that they were the same motors except one has twin turbos. wrong. thats why ive been saying n/a.

Read about it here on a GM website. They were a little bit butt hurt by it.

It was also mentioned in other articles from when the motors were first released to the press.

I think for what you want the truck to do, both engines are more than adequate. If I were looking to buy a new truck today, the biggest consideration I would worry about is price. With all the deals on the 2010 models, you will be hard pressed to make a better argument for the 2011 models.

My next concern would be reliability. I see no reason the 3.7 would be problematic, but it has not been tested in a pickup application and its true performance in this arena remains to be seen. The 4.6, on the other hand, has proven itself to be a pretty good engine.

Performance would be my final consideration. I think the 4.6 3v and the 3.7 should be fairly close in terms of unloaded driving performance. I'd love to see a drag race between two trucks that are otherwise identical. My 4x2 SCrew 4.6 3v with the 3.31 axle seems to have plenty of cajones. I am not sure if the 3.7 could hang with it despite having 10 more horsepower because it is down on torque by a little over 40 pound feet. I think the power characteristics of the 4.6 3v lend itself to moving a trailer a lot better than the 3.7 which is rated to tow a max of 6100 lbs vs the 4.6's max tow rating of 9800 lbs.

If you had asked about the new 5.0 vs the 4.6, this would be a completely different discussion. I, however, still would have to consider the lower price of the 2010 models, but only if I had to buy a truck right away. I think you are going to see similar deals on the 2011 models in several months. So, if you aren't in a hurry to buy, you might want to wait it out and see how the new engines are doing in the real world plus get a better deal if you should decide to buy. You might even be able to buy a 5.0 equipped truck for a decent price in a few months and really have a truck that puts a smile on your face.
