5th gen 4Runner underpowered

Yeah, any Internet engineer can tell you they should've put the redline at 5k instead of 6k. But of course the morons at Toyota aren't smart enough to figure that out.

I drove the V8 runner a few times .. no downshifts when driving on a hywy with hills . V6 sure does happen downshifts even with no loads/tow ..

towing with this V6 in mountain areas you have to put it in a lower gear and reduce speed .. sure gonna loose MPG ..

anyone have a dyno graph on the V6 torque band ?

It's not pretty.

As others have mentioned...there are some options to help. URD MAF
calibrator, y-pipe or just splurge for the supercharger.

A sprint booster or pedal commander won't help your towing situation, but it will help eliminate the throttle lag and at least for "normal" driving around town, etc, it does make driving the care more enjoyable.

Good luck.
 
I bet you're a lot of fun at parties.

I don't remember Toyota advertising the 4Runner for towing up mountains at 80+mph. Sounds like the OP needs an F350.
 
Point taken, OP, and one that many of us have also experienced. The outdated transmission is woefully evident when towing - and even worse in the mountains. I once towed a 12ft fishing boat from NJ to Atlanta and got about 9 MPG despite sticking to 65-70mph in the right lane. Pushing anything beyond 70 MPH seemed like "too much" which is not anything I ever experienced with a 4th gen V8. To have a vehicle like this that feels inadequate to tow a small boat or trailer for any distance is inexcusable.

As you have likely noticed, when someone posts something critical about the 4R, most members revert back to an elementary level of communication and antagonization to try to discredit the valid point and poster.
 
We recently bought a 2010 limited v6 4Runner 6 months ago. I currently have a 2004 v8 sport edition with oversized tires, a 2006 stock height limited v8 and a 2004 SR5 v6. Our family loves 4runners I guess! I just got back towing a 2400 empty pound travel trailer from St George ut to Salt Lake City. Speed limit is 80 mph I kept the truck at 80- 85mph most of the way no trailer attached I was getting 14 mpg unloaded no trailer on the way to st George. Horrible. On the return trip with the 2400 pound trailer heading back to salt lake going up in elevation it really struggled to go any faster than 60mpg unless I kept downshifting to 3rd avg grade, It would move like a raped ape in 3rd but once it upshifted to 4th you could tell 4th was far to tall as RPMs and speed immediately dropped. Very annoying, It was a late night tow and of course after 9+ hours there and back I wanted to get home. Getting passed by diesels like I’m stopped. It was 50- 60 mpg or less the entire way unless on flat or Downhill or if I’d rev the crap out of it in 3rd on hills watching gas gauge plummet to stay 65-70. It just kept gear hunting 3-4 far more than any v6 I’d towed with before.
I usually tow with my v8s but my wife likes the comfort of the 5th gen and I thought what the heck. Never again! Probably took years off it’s life with all the gear hunting.
The new v6 auto tranny is awful for towing they geared far to high in 4 and 5 trying to achieve 22mpg rating, sure I can achieve 19 -20 all day long if I’m under 70 but I didn’t realize how much it would kill the rating to go 80-85. I didn’t realize how effortless the v8 power made a long trip.
Until I towed with this thing,
What’s beyond me is the 4Runner has always been known as a legendary off road vehicle for active outdoor enthusiasts. Most people into those activities are going to be towing and have extra gear. It seems Toyota is more concerned about appeasing the epa and putting 20 inch wheels on to keep more people on the road than off it. Since we’ve owned it I’ve felt it was pretty gutless unless you floor it then it’s fine. Ive read countless posts stating you just have to press the pedal harder. The truth is the motor does have good output for its bulky weight. It’s just the gearing, the throttle mapping and the torque curve or usable power band is sub par. Sure it will get the job done towing and is fine unloaded but if your looking to tow anything other than a utility trailer def get an older 4th gen v8 or v6. Even my 04 v6 towes amazing.

1) 50-60 mpg! Amazing!!! :)
2) You should not tow in 5th gear
3) The 2005+ 4th gen V6 (and all 4th gen V8) 4runners have the same transmission as the 5th gen.


I'll be the first one that will state I wish the 5th gen had a V8 option, but the 4.0 V6 is decent, and better than the 3.5 that is rumored to replace it (IMHO).

That said, I previously owned on 03 V8 4runner, and I did appreciate the extra torque for towing. However, I towed a 5,000 lb trailer through mountains with our 2012 limited 4runner and was able to keep 70 mph in 4th gear no problem and felt I had power to spare. The current V6 is essentially the same engine as the old V6 with a bit more power. I also had an 04 V6 4spd. That 4 speed tranny sucked. Didn't come close to towing as well as my 5th gen. Simply put, maybe there is something wrong with your 4Runner.

I'm relatively new here, but it seems people are pretty openly critical of the current drivetrain. It's proven reliable and dependable, but is unexciting. I mean... it's a 4.0 V6 that wasn't cutting edge when it was first produced and it's now 10 years old. It also has the aerodynamics of a brick. I think people are really only quick to be defensive when someone is critical of something they should have known BEFORE buying a 4Runner. It has the same towing capacity as a non-hybrid Highlander. The cheapest F250 has 246% the towing capacity!
 
A chevy small block and a bullet proof 6 speed would be better, push rod or not! The 4.0 is a great engine for what it is but a small block is a great engine and it sounds great too plus parts are cheap

The engine is pretty much bullet proof

on the flipside -

The engine and transmission are the exact reason I'm hesitant to buy one..
The engine has no guts and no excitement

Im coming off a 400hp car and I realize an SUV is not a sports car. On the flipside I dont know if I can tolerate the engine once its got a lift and tires strapped to it...

Re-gear to 4.88. You won't be screaming down the highway at 105 mph, but you'll have plenty of take off power and towing power.

Other manufacturers rush out high horsepower motors and that's exactly why they fall behind Toyota on reliability, they rush it out without proper testing. If you like a lot of horsepower and aren't worried too much about reliability, the Ford Bronco is being released in 2020.

So many syllables.
