Isn't the Sienna the fastest production minivan and it's 0-60 is 7 seconds?I really am confused why we're talking about drag racing trucks. It's like drag racing minivans
Hemi Ram's are 6.4 seconds no? I realize that most coupes and some sedans will be beating us pretty handily but I refuse to believe that we can't outrun a minivan…

My wife's EcoBoost Ranger in sport mode could easily take me in a straight line...but at the end of the day it's still a Ranger.

I'm just not living in a world where a 6.4 second 0-60 is fast. I mean that's "hold the steering wheel while I put ketchup on my cheeseburger" acceleration. 
Not to mention it's more like 12 seconds for those of us with 3.21 gears.

The top speed is capped at 105, which can be reached in 5th gear, even with a 3.92. 8th or 7th won't come into playI'd just shallow stage to get a jump on the light. The 3.92 truck will tach out in 8th (my 7th) so I'll have an "extra gear" and run them down at the end and take the line by a bumper with the higher trap speed.

You couldn't give me one day to dream!
You've crushed my dreams of being king of the gear mountain.
I'll stick with "putting ketchup on my cheeseburger" as people blow by me. I'll end up passing them down the road when the cop pulls them over for testing their speed limiter.

Is that true? Capped at 105? Mine is capped at 118, I just assumed they were all set the same.

105 is the limit, beyond that most truck tires start to come apart. The TRX has special tires rated to handle the 118 limit

I bought mine as a recreational vehicle anyway. It's to haul camping and hunting gear, beach trips and the occasional trip to the dump.
My plan is around 5000 miles a year.

We're I'm at, I'm faster than 90% of the vehicles on the road. It's all overweight, underpowered mid and full-size SUV's and other pickups, lots of em HD's and/or diesels. Some 4-banger coups and sedans and other things that's can't keep up, especially passed 70, and then the occasional X5, Camaro, or Mustang that would smoke me.I'm just not living in a world where a 6.4 second 0-60 is fast.

I never thought about that though. How what kinds of vehicles people have in your area would affect your perception of how fast you are.

Yep. They are pretty quick for a big, heavy truck. If you're trying to out accelerate someone, just know your competition.

You obviously never rode with my grandfather.. He had two speeds. Accelerate and decelerate. Both as quickly as possible.Yup, 3:21 grampa gears....

It's just the 3:21 guys that come on saying "It's a truck, it's not fast", "Why would anyone think a truck is fast?", "If you wanted fast you should have gotten a challenger" etc. Well, I have a pretty fast Town Car too. Yea, the TC and the truck will get eaten alive by a Hellcat or a Mustang with a 5.0 Coyote in it but like @AngelPhoenix said, it's faster than most.
At least I'm not as slow as the guy behind me with 3:21 gears!

Well he probably chose 3:92 gears too!You obviously never rode with my grandfather.. He had two speeds. Accelerate and decelerate. Both as quickly as possible.

A gen5 ram? Yeah they are all capped at 105 unless it’s tuned.
Unless you have very different tire sizes that’s throwing off your Speedo.
Something to do with the driveshafts is why they capped them. Not so much the tires.
