My # 1 thing that disappoints me is the engine. The crappy gas mileage and relative lack of performance.
I have the Hemi w/eTorque. I'm getting 14.5 MPG, hand calculated, over the last 7000 miles. I never expect to get what the sticker says. But, this is kinda ridiculous.
I wouldn't mind the mileage, if it was laying down 450 - 500 HP and 450 - 500 ft-lbs of torque.
But, the engine feels/drives just like my '09 did. And gets about the same mileage (with the same rear end gearing and with an 8-speed tranny versus the 6-speed in the '09). And that's sad.
What's even sadder is that my truck has been in the body shop now for just over 2 weeks (getting fixed after I backed into a pole). I have been driving an F150 rental for over 2 weeks now. I like my RAM better in every way - except the engine. The Ford is an XLT, which is a low trim level. I figured it must have the 2.7L EcoBoost. It takes off from a light better. It accelerates around cars when passing better - for the times when I just tip into the throttle for gradual acceleration. When I put it to the floor, it's hard to say how the acceleration compares to full throttle on my Hemi, but it certainly doesn't feel hugely different.
So, just now I went out and looked under the hood of the Ford to confirm what engine it has. It's a V-8! So, it must be the 5.0L. It drives nicer (engine-wise) than my Hemi AND it is getting way better mileage. At least according to the Ford's onboard computer - I have not hand calculated it. I drove the Ford to NC last weekend. Same trip I've done in my RAM. The RAM gets 16-ish MPG on that trip. The Ford 5.0 V8 got 19.something.
Before I bought my current truck, I was holding out for a new RAM with either an EcoDiesel OR a bigger/better/faster gas motor. I only bought the new truck when I did because of the June rebates. I could not pass up 26% off MSRP. When the EcoDiesel proves itself, or when Dodge comes out with a better gas motor, I will be heading to my dealer to look at a trade-in.
I have not driven an F150 with the high output 3.5 EB (like they put in the Raptor and now in their Limited trim). And now I don't want to. I bet I would like it a LOT better than the Hemi... In fact, if the ED turns out to be problematic and they don't start offering a better gas motor, I would even consider going back to Ford to get a Limited with the 3.5 HO EB.
