VVT-i is variable valve timing... nothing to do with ignition. Although both are presumably the 1GR-FE engine design, I agree that this is a meaningful equipment variation within the engine. It allows the 4Runner (dual VVT-i, meaning variable on both intake and exhaust cams, not just intake) to maintain torque output at higher speeds, thus producing more power.

Leon, are you asking about the difference between 4Runner and Tacoma (as Jim assumed), or the difference between the 5000 lb tow rating quoted earlier and the 4700 lb tow rating you are seeing?

If it is the tow rating, then at a quick guess, I note that different levels of standard equipment change the base vehicle weight, leaving more or less for the trailer rating. The trailer rating is normally for base equipment, and actual capacity as equipped is often less.

But if I look at Brent's word problem up above, it looks to me like both the us and Canadian models generate 270 HP and 278 ft lbs of torque. But Brent mentions a towing capacity of 5000 lbs, and the toyota web site says towing capacity is 4700 lbs. my assumption is that Brent is looking at the Canadian model and the website I am looking at is the American model. Both say the are following the SAE standard. Oh well. More a curiosity question

I was asking about the tow rating of the 2 versions of the 4 runner. You point about different weights makes sense

So, Leon, you are talking about the difference in 4Runner tow ratings, not the difference in engines. The engines are usually the same for both countries, since government regulations are compatible and the vehicles come out of the same factory for both markets. Yes, Toyota USA lists 4700 pounds, while Toyota Canada lists 5000 pounds. If you're curious, you can download the owners manual from Toyota USA - it is usually the same manual for both countries.

SAE Standard J2807 sets requirements for testing; a manufacturer can set any rating at which the rig passes the test standard, so they can always go lower in rating than the vehicle's capability if they want to allow more margin for user error. In this case, I think it's probably equipment variations, but I haven't compared the equipment feature-by-feature.

Thanks for shedding some more light on this question, folks. It would be interesting to know the thinking that Toyota puts into setting its tow capacities, especially when they have to factor customer expectations and satisfaction, legal considerations, the SAE standard, and marketing into the equation.

I'm sure looking forward to experiencing firsthand how well our 4Runner handles towing the Escape 21, but can't do so until ours hatches in September.

Not having towed before, I have no point of comparison. I just want to be sure we aren't using a vehicle that is not up to the task, and compromising safety for ourselves or anyone else on the road.

Two friends tow a 21ft with a Highlander and another tows with a 4-Runner with a 4.7V8.

How do the folks with the Highlander do pulling the 21? That is the tow vehicle I am most likely to buy. Thanks much

The Toyota Canada website lists the newest and most capable Highlander's tow capacity at 5000 pounds, and rates the 3.5 liter VVT-i engine's output at 270 hp @ 6200 rpm, and the peak torque at 248 foot-pounds @ 4700 rpm.

The GVWR is 5997 pounds, and the curb weight is 4508 pounds.

It has a 6-speed transmission, which might help, and a transmission fluid cooler.

The Highlander is a crossover design, while the 4Runner, FJ Cruiser, and Tacoma are all body-on-frame vehicles.

Little hesitant to jump in on this, but here goes. We have a 17B we bought in September and started with a 2011 Murano rated 3500 lbs. tow capacity. We figured no problem as the dry weight for the 17B is 2100 lbs.
We traveled about 2000 miles and started wondering if it was really up to the task. Bought a 2013 Highlander SE this January and love the difference, but don't think I would want to tow another 1000 lbs. with it. I have owned a 2003 Sequoia and a 2008 Buick Enclave. I don't believe the Enclave would be much different from the Highlander, and for what its worth I didn't like the six-speed tranny on the Buick. They went to that on the '14 Highlander and I prefer the five-speed. Am pretty frustrated with the depreciation we ate over the years....should've kept the Sequoia honestly, but we were downsizing, and didn't know we wanted a trailer. If I decided we had to have a '21 I would think seriously about biting the bullet again and get a V-8.
