I currently have an 05 T4R V8 that has a towing capacity of 7,700lbs. I am wanting to purchase a new 4runner but the towing capacities are only 5,000lbs, which is right at about what my boat weighs. I'm really bummed that a new 4runner just might not be an option anymore. I want to get a new TRDPro model but I'm thinking I wouldn't be able to tow my boat very well. Am I right? Are any of y'all towing that much? Thanks in advance, Rebecca.
SAE2807
Here's what I *think*. I think you are comparing Apples to Oranges. Let's apply a little logic. Your V8 produces
similar hp/tq to the 4.0, lower rpm agreed but
pretty similar. The V8 does have a better tq-@-rpm advantage, but not dramatic. 4G chassis/suspension is same-at-best, 4G brakes are inferior. So why a 2,700# difference?
I think it is primarily due to MANUFACTURER'S TOW RATING. Prior to 2011, Toyota (and
every Mfgr) did
their own tow ratings. So, your 7,700# rating was done by Toyota engineers, and I have every confidence it is reasonable. Toyota
was the first mfgr to begin rating it's vehicles to the newly established SAE2807 tow standards, hence the dramatic TR drop with the 5th Gen.
If you think that V8 is wholly responsible for the different tow rating, sorry but that is just not realistic. I agree that the seat-of-the-pants meter favors the V8's lower rpm tq, but if I
had to tow, say 6,500#, I'd pick better brakes in a 5G over a V8 in a 4G any day. If you think a 4G is a better TV than a 5G, knock yourself out, but as Spock would say, "it's illogical Captain".
The biggest concern I'd have is liability, not reliability.
This will probably start a shitstorm of opinions ... so, just my $.02.
