Default I Wish These Would Have The 4.0L 251 v6 Option

The 3.7L 210 hp v6 is so outdated!

Though outdated, when compared to the 07 and older 4.7l, it actually does pretty well. My 4.7 V8 is only putting out 235hp at the crank. Unfortunatly, the 3.7l gets about the same gas mileage as my V8. Dodge has some work to do on their engines, thats for sure. It may be why Chrysler isnt doing so well, but atleast they are doing better than Toyota. Toyota was the only car manufacturer in the US to report a loss last quarter of -3% .... everyone else gained. Hyundai sales are up over 40% from last November, and their V6 has some serious power.

Even Ford is putting 300hp out of their V6. IMO, Dodge messed up in 08. They improved the 4.7 and 5.7 to have power that compares to alot of other vehicals in the same class, but the 3.7 remained unchanged.

He he, do like the jeep guys and buy a 4.0, bore it out to a 4.7L stroker and drop it in. I hear you though on outdated engines. I think about it every time I drive the wife's 4.6L V8 Borrego. Why couldn't we get an engine like the 4.6L Tau 286 ci putting out 380 hp, lol.

The Jeep 4.0 is from the 'real truck' engine era - lower HP, lower RPM, and lots of grunt.

The newer Chrysler 4.0L from the Pacifica isn't much different than the 3.7...high RPM torque, rated HP achieved only at redline. You'd still have to wring it out to get going. It might be a bit quicker, but I'm not sure it would feel much different than the 3.7.

I like my trusty 3.7...iron block, 2V per cylinder, chain timing (which the 4.0 has too), graphite-iron bedplate (very strong), electronic throttle with coil on plug (modern enough), and despite all that, only makes 210 HP. That translates to reliability in my book.

Also look at it this way - 226 cu in, 210 HP = 0.93 HP/cu in...a Hemi from this era barely edges it out at 1.0 HP/in.

I'd look for the Pentastar V6 in the next Rams.

Even though Chrysler isn't doing so well they still really need to update their whole power train badly. They should at least try to make new engines that way they will see some sales.

I hope they will put the new pentastar v6 in these too. Manufacturers seems to be shying away from small trucks and thinks everyone wants a huge rig with gas guzzling v8.

it could be worse, we could be driving a full size RAM with the 3.7, i find the 3.7 underpowered in the DAK so i could only imagine how underpowered a V6 RAM would be.

Ford dominates in gas engines right now, IMO. The EcoBoosts are looking like very durable, very powerful mills, with a severely abused 3.5L recently completing the Baja 1000. They have ditched the 4.0L V6 for an impressive 3.7L, and the 5.0 and 6.2 V8's will be making insane power once the tuners dig in.

Dodge needs to get a 6 speed automatic into the Rams. With modern engines making all their power and torque in the high RPM range, the 545RE's 3.00:1 1st gear doesn't cut it. Most 6 speeds start above 4.00:1, and most are 4.20+:1, with dual overdrives. That's the kind of transmission these modern, high RPM motors need to maximize performance.
