V6 vs V8 guidance

took mine out yesterday. can't comment on the fuel change as the wife drives it now. All I figure is that no other car, that I am aware of, that I have driven had one. None of my cars have blown up. My 2007 mazda6 doesn't have one. It really isn't a necessary item. The only real impact it likely has, is to restrict airflow, especially given how thick it is. Tossed it and I'll never look back...
 
I gotta say, I test drove a 6 and it did feel plenty fast.../QUOTE]

I have to say I agree. I drove the 2 back to back and there's just not enough of a difference to make the V8 worth anything more unless you're towing. The V6 does rev higher than the V8. The torque is more in the V8, but the V6 is in the horsepower sweet range longer. The V6 had the pull for me so it was worth it. I've towed about 4500Lbs with it just fine around town, so I'm not going to complain.

The V6 is a great engine and it's been an awesome truck!
 
Im also from SoCal, and have a 06 V6 2wd, and love the engine. Plenty powerful to haul gear and friends around, yet efficient when your stuck on that 405 traffic for a few hours.

I've been getting 23mpgs frequently, but thats around 90% freeway driving.
Also have been putting an average of 24,000 miles per year on her, and love the fact of how easy it is to change the oil (a 10 minute job).
 
....

This statement is not correct if are comparing V6 to V8 on 2005+ models. In 2005 V8 got dual VVT-I on intake, so torque curve for that engine is impressively flat across RPM.

I also did a lot of “test drives” when I was looking for upgrade from my 3-rd gen 4Runner and when I drove V6 and V8 configurations I actually felt that V6 was definitely weaker, noisier and even not as smooth as my 3.4 L in 3-rd generation. That is just one more proof how subjective it can be…
As far as gas mileage, on my last long family vacation (we went from Texas to Yellowstone and back totaling 3200 miles) I got 21.6 mpg (calculated) and that including 85 mph joyful ride though parts of Colorado and Wyoming).
I know I have lost about 1.5 MPG since that time because I went with AT tires and lift, but I still think it is still very good for V8, 4x4 and heavy truck.

Now back to the original poster: I would recommend do many test drives and go with what YOU like and waht YOU want the most.
 
I debated between a V6 and V8, and I wasn't going to be doing any major towing, so opted for the V6. I am very happy with my decision. I have had a lot of V6's in various vehicles, but this 4.0 liter motor is the most powerful.

We just came from a trip to the mountains, climbing from 1000' elevation to 7500'. We had just an average load, but I had surplus power running out of my ears, so to speak. It just powered up steep highway slopes as fast as I would ever want or need to accelerate.

Gas is high and going higher. We will likely see $5-6 per gallon, maybe more, in the not too distant future. l've got nothing against the V8, but I figured why pay extra for gas when the V6 has all the power I would ever need.

Get the V6. You'll be glad you did, particularly when gas gets to $6-7 per gallon.

Now, gas is less than 2.
 
Just prolonging the pain... :D

As for me, I was leaning towards a V8, but I looked at 4 of them, and ever single one had no maintenance done to the engine, so a timing belt job was right around the corner, and the sellers wanted top dollar even after bringing this up. If I found one with a reasonable maintenance history, I probably would have jumped on it.

But the V6 rarely leaves me wanting, even when towing around 4500-4700 lbs. The only time I'm wishing for more power is climbing an incline merging onto a highway from a near stop. It pulls fine through 1st and 2nd, then the large drop in revs really kills the acceleration in 3rd. But given the V6 is right in its powerband there, I don't know how much faster a V8 would really be. Slightly, but probably not enough to make a huge difference in the towing experience.

The V6 definitely makes the front end feel lighter, so it does turn-in better, relatively speaking for an SUV at least.
 
The two vehicles I've found are both 2WD, SE trim:

2005: V8, 71k miles
2006: V6, 63k miles

Now a little about me...I live in SoCal, don't do any towing, but do plan on using this car to haul people and luggage in road trips and snowboarding trips. No offroading plans (2WD anyways).
If you haven't decided, I would look past the engine type and ask about the options on each vehicle; sunroof, upholstery, condition, etc., and base your decision on that.

I live in the mountains and I have been perfectly happy with mine. We just got 5-6 inches of snow and I haven't had problems getting around our hilly town with 2WD.
