C'mon, colonel. Quit spouting diatribe. There's not a damn thing wrong with the EcoBoost other than it outperforms anything else in its size, and obviously whatever engine you fancy so much. I have nearly 60k trouble-free miles on my EB. Talk to the Ford service guys and when given the sheer number sold vs. the number coming in for service, the failure ratio is quite low. You obviously don't follow the auto industry much. If you did you'd realize how stupid your comment about transmissions is. I'm not even going to tell you why. You need to find out for yourself.Your warranty statement also makes me laugh. I'm reminded of a line from one of my favorite movies: "Why does he put a guarantee on the box? ... Because he knows all he sold you was a guaranteed piece of sh!t!"

The five-link coil design incorporates support at all major points of force. Leaf spring suspensions struggle to combat axle wrap by staggering shock absorbers on the front and on the rear of the axle tube. The design of the five-link coil system functionally resists unwanted axle rotation. Leaf spring configurations also lack lateral support, forcing the leaf ends and shackles to hold against lateral loads one reason leaf-sprung rear suspensions shutter on rough surfaces. Because of the unique five-link axle control and natural rotation, U-joints in the driveshaft run smoothly and with less vibration through the suspension's range of motion, an advantage not shared with leaf springs. Another benefit of coil springs is less unsprung mass and elimination of stick-slip friction found between the leaf springs. Additionally, links are engineered in-line with frame rails, so overall packaging is better, not to mention an overall weight reduction of about 40 pounds when compared to a leaf-spring configuration.

Can someone point me to a website/magazine that will explain the pros/cons of the coil springs?

No surprise. The Ford V6 Ecoboost has been problem prone of late, more costly, and does not do as good with mpg as GM's muscular V8...that and Ford's weak powertrain warranty makes me wonder why someone would not want to go with the Ram or the new GM models. But GM needs to get the 8 speed in its trucks like Ram to add 1-2 mpg more. Ford and Toyota should think about that too.
