No! i have just checked the figures and tested the figures. With same axle ratio and weight for weight the F150 is the same or faster depending on tests. Check for ya self. Here's a quick comparison for you. There's plenty about.

Even this comparison doesn't put the ford equal. This test is with Dodge's worst possible gear/tire configuration. Those steep tranny gears in the ford definetely give it a a 0-30 advantage ( in this test .34 seconds 0-30 ) but now lets look at 0-60 ( dodge take a .38 second lead at 60 after being behind by quite a bit to 30 ) Here is a comparison from motor trend with the dodge and ford both having their best available gears and with the dodge still having the 20 inch wheel vs 18 inch wheel disadvantage.

0-60 7.6 vs 8.9 for the ford. That is a pretty significant difference.

0-60 7.6 vs 8.9 for the ford. That is a pretty significant difference.
Lol thats the chart that shows the lariat as 8.9. Right this has been talked about before and weeks ago i even tested my platinum 0-60 because their figures are nothing like anybody Else's. My platinum run a 0-60 in 8.6 with full tank of fuel and 2 people. Me and my wife, She was timing. Now that is what they have been quoted almost every site i have seen and the lariat being heavier and with better axle ratio must be able to beat my platinum. Now thats also the first test i seen a crew 4x4 ram get low figures like that. I have seen them for the striped out basic models which weight sod all but not for the crew 4x4's. There's a thread on here somewhere with way more comparisons from many places and they all show with same axle ratio and same size trucks they are almost identical. I guess the ford would def be faster all day long with E85.

Oh and here an exerpt from the trucktrend test:

For our testing, Dodge loaned us two trucks that couldn't be more different: an ST regular cab, 4x2, V-6, listing under $24,000 and a fully loaded Laramie Crew Cab 4x4 with just about every bell and whistle possible, totaling out at over $50,000. Most judges commented on the hugely improved interior layout and material choices in the Ram, noting this could be the best Chrysler-originated interior ever. Materials, seams, touch-points, and overall function are hugely improved and competitive in the segment. Likewise, both Dodge powertrains drew praise from judges as the smallish V-6 held its own during our on- and off-road segments; while the throaty 5.7-liter Hemi tore up the test track with a blistering 6.9 seconds to 60 mph in fully loaded dress. (The R/T we tested did 0-to-60 mph in 5.7 seconds. Wow.) Also, as we test our trucks with a quantifiable load (75 percent of max towing capacity), it's worth noting the Hemi Crew Cab was slowed the least by its burden

So i suppose you think a fully loaded crew cab 4x4 f150 would run 0-60 in 6.9 seconds like the fully loaded crew cab 4x4 ram? Like i said.... you smoking something good!!

One note Bsimmer... I am not trying to be rude to you i just like a good spirited disagreement as much as the next guy!!! The f-150 has many great things but performance is not one of them. Oh and until dodge wakes up and puts a good well geared 6 speed tranny in their trucks, they are gonna be playing second or third fiddle to the tundra and the new 6.2 chevy's.

Everyones allowed to believe what they want and having driven both of them i had the dodge ram for a weekend and now a owner of the f150 i can also tell you that they don't at all differ in performance. There's 2-3 reviews showing some crazy 0-60 times for the rams then there's 10+ showing normal figures that you can believe. I seen figures of 5.8 secs for a crew 4x4 Laramie and plenty of 6.5's and i know for a fact they are all false. When you see test after test after test showing 8.3-8.6 for the Laramie then you start to see there's something up with these figures. I think what a lot of reviews are doing is quoting the smallest fastest models performance as the Laramie's performance. There's going to be a massive different between the two.


here's some more from another site.

March Car and Driver
Chevy 5,540 lbs 0-60 7.6 1/4 mile 16.0
Dodge 5,840 lbs 0-60 7.4 1/4 mile 15.5
Ford 5,880 0-60 7.9 1/4 mile 16.2


March/April Truck Trend

09 4X4 Lariat Screw w/3.73, 0-60 7.6, 1/4 mile 15.8
09 Dodge 4X4 Crew O-60 6.9, 1/4 mile 14.8

Ford 5,880 0-60 7.9 1/4 mile 16.2

So you don't believe truck trend got 6.9 with their crew cab 4x4 laramie and 5.7 with the single cab r/t? The 6.9 doesn't seem to be too unrealistic since they have the 3.92 gears and the 7.4 second 0-60 you quote above from car and driver is with 3.55 gears. Seems about right to me!! All this over this quote from you:

Well if the new trans seems to have give the engine the boost it needed. It has no problem staying with and matching the Dodge ram with the hemi on perfprmance and i always hear people going on about how fast they think they are. So yes the new 09 is doing great so far.

I still haven't seen a single test that backs what you claimed. Even your own examples ( quarter mile times 15.5 vs 16.2 and 14.8 vs 15.8 ) prove me right. That is between 7 and 10 car lengths in 1320 feet. I don't consider that " staying with and matching the dodge ram with the hemi on performance" Thanks for entertaining me Goodnight!!

It could be possible depending on ratio's, weight, fuel, person driving. But what i do know is there nothing in it anymore. You put the same weight truck with the same ratio and there's nothing in it. Your reaction time would be more of a factor.

could be, all i know is that my mpg has steadily improved over the past week. when i bought it it was getting 17.5 mpg, now that i'm used to it and drive it with a light foot its steadily climbed to 21mpg, now there are those who think i'm stretching it but i't the gods honest truth. but for those folks i say nothing i say will convince them other wise, they disagree with everything and anything so its better to just ignore them and maybe they will fade away.

No, jda has a 5.4 XLT, single cab, short bed 4X4. It's a very nice looking ride.

I could believe the 21 mpg if it is all highway driving at 65mph or less at a low elevation with very flat terrain. There is no way 21 mpg of mixed driving or city driving. Or he could be one of those hypermilers that coast as much as possible, shuts their vehicles off a red lights, and does 0- speedlimit in an eternity. There are people doing this stuff now days to save every drop they can. Usually these people won't be seen in a truck though!!!!

The Ford and Chevy both have MUCH better geared transmissions as well. Much lower 1st gears for that initial grab off the line, and closer spaced ratios to keep the engine running in its sweet spot. While the Dodge's transmission has a fairly high 1st gear (around 3.00:1 compared to the ford and GMs 4+:1 1st gear), and then the Dodge's 2nd gear is 1.67:1, which is so steep compared to 1st, that it nearly cuts the RPMs in half and actually throws the engine below the peak torque RPM.

I have heard of Reg Cab/Short bed 09 rams with the 3.92 gears and 17" wheels hitting low 14s, very very high 13s in the quarter mile stock however, which is pretty significant for a stock truck if you ask me

Mr. Frdtrtnv8, I went from the 05 FX4 to the 09 FX4, with the 5.4 engine and 3.73 rears, and YES, the 09 has more power and quicker acceleration, it has a much smoother ride, the seats are higher, and there seems to be more window vision.
The BAD: The frame and suspension on the 09 is weaker than the 05, the frame on the 09 is a welded two piece section where the 05 frame was one piece from front to rear bumper, the big lower control arm is gone, the 09 has a thin sheet metal lower control arm, ( the front suspension looks like the 97-03 F150 except it has coil springs where those has torsion bars )

I am worried about the front suspension, I once owned a 03 and was always replacing the front ball joints, I hammered my 05 off road and never had a ball joing go bad.
