Here's an excellent review that just hit the web. Besides the amazing gas mileage, buttery smooth operation, and being "wonderfully quiet" at idle and cruising speeds, the writer talks about the excellent acceleration of the 1500 Diesel. Here's a little excerpt:
Check out the whole review HERE. It's a great write up.The pull from the diesel even feels the same as Ford’s EcoBoost, perhaps cutting the Hemi’s own grass a little, too. Sure the Ram’s 5.7 Hemi gasoline V8 is very fast, sounds terrific and is delightfully smooth; but the Hemi and EcoDiesel are not grossly far apart when it comes to acceleration. Like the Hemi, the EcoDiesel is married to a TorqueFlite eight-speed transmission made by ZF that makes excellent use of the diesel’s low-end torque. The union of diesel and eight gears is possibly the best combination I’ve ever driven in a half-ton pickup.
