Re: Pros & Cons 6cyldr vs 4cyldr

I bought a v6 for my fiancÚ. Didn't like the lack of power on the 4 cylinder for a vehicle this size. Easy decision as we're not too concerned with a few less mpg's. I drive a v8 mustang and she used to drive a 4 cylinder Acura. She loves the v6 compared to the 4 and also test drove both the 4 and 6 before deciding she liked the 6 better. Still getting 18-19 mpg with 70% street 30% highway use

Re: Pros & Cons 6cyldr vs 4cyldr

I got the 4 cylinder because of the better gas mileage (less fuel costs) and less initial cost. I find it has plenty of power and I haven't needed to truely rev the engine yet. I also don't tow anything so didn't need more power for that either. I think unless one needs the extra power for something or feels they can't live without a V6...the 4 will work great for them.

Re: Pros & Cons 6cyldr vs 4cyldr

I've got 16k+ miles on my 4 cylinder FWD Terrain. The vehicle i gave up for it was a 2007 Ford Ranger Super Cab 4x4 with a V6. Due to initial cost and MPG's, we chose the 4 cylinder over the V6, even after test driving both.

I would prefer the V6, but the 4 cylinder does a very good job of moving the vehicle with no problems. I've taken it on two round trips from Cleveland to Charlotte and even going through the mountains, it did surprisingly well with 3 passengers + luggage. I don't tow anything, so that aspect didn't factor in at all.

I was getting 16-18 MPG in my Ranger. I'm averaging 25 MPG in my Terrain with about 65% highway driving. I'm completely happy with my vehicle and have no regrets about getting the 4 cylinder.

Re: Pros & Cons 6cyldr vs 4cyldr

To be honest I didn't "feel" the extra torque and power from the V6, and most of the reviews I read, also didn't. I opted for the 4cyl, and had a hard time getting my FWD 4I. I wanted most of the bells and vistles I could get on the 2LT trim, but most available vehicles close to my needs either had AWD or the V6 or both, something I was set against. I do a lot of highway driving, and I don't tow anything. Actually, the dealer was going to subtract the V6 price option, just to sell me something they had on the lot. But I calculated how much more would cost me to drive the V6 vs the 4i, and it wasn't worth it. In the end I had to wait, but at least I got what I wanted.

edit:

I'm also hearing the V6 needs more frequent oil changes than the 4

Re: Pros & Cons 6cyldr vs 4cyldr

I had the Terrain 2011 for one year and 29k miles with the I-4 AWD

I now have the 2012 Terrain AWD with the V6..I have about 1300 on that.

I drive alot, I use it for work.. I went with the I4 at first for the MPG.. but I didnt get good MPG.. i was around 19-21 MPG on the I-4.. I think it had enough power, it just really gets loud when you give it the gas to get it to go..I had an I-4 in my last vehicle, 2006 HHR with the I-4 2.4L. I had no issues with that engine..so I thought i would be fine with the I-4 on the Terrain too.

now I was fine with it, I just felt like the Terrain, to me, being a heavier vehicle than my HHR, that the engine really worked hard...again, this is my opinion, and obviously my driving habits!

Now that I have the V6 and Im getting 18-19 MPG..(so not really seeing any change in MPG) and the engine is quiet, and has plenty of power..moves quick getting on freeways or passing...

I wish that I would have gotten the V6 in the first place with the 2011..

Also I changed the oil on the I-4 every 7k..my oil life at 1300 miles shows 78%..so we will see how the oil changes go..( no, I dont go by just the oil life monitor...)

Re: Pros & Cons 6cyldr vs 4cyldr

I have a 4 cyl and the power is fine. You should drive the vehilces. The best mileage I have gotton in 28.5 but in mixed driving usually in the mid 20's. Looks like gas will be going real high this spring (Starting to go up now). You'll need to save the extra cost for the 6 and better mileage of the 4 to keep your costs down. This is a personal choice.

Re: Pros & Cons 6cyldr vs 4cyldr

If you don't anticipate doing much of any towing with this vehicle and you don't have a heavy foot, I'd go with the 4 cyl. Whatever you do, I would avoid the 2011 4 cyl's like the plague - particularly the ones with build dates between Feb 2011 and June 2011, you can find those issues in other thread on this forum.

If you like the extra power, then go for the V6.

2011 I4 Equinox LS bought 3/31/11 : after multiple failed repairs for stalling/start-up noise issues, pursued a GM-assisted replacement. GM agreed, and paid several thousand dollars to get me into my current vehicle...<br /><br />2012 I4 Equinox LS bought 02/28/12

Gee, if you can't feel an increase of 50ft lb of torque, then you must be sleeping while you drive! jk of course[/color]

Well almost perfect [/color]
