The way the Ford Ecoboost engine mount system works is that the two side mounts provide a rotational mounting point and the bottom of the engine is free to swing like a pendulum if just these two mounts are installed without a lower engine mount. Now, if you take the stock engine mount and put it in place with its horizontally mounted bushing and you apply some power, it will help stop the engine from swinging but you are now stressing the bushing in two directions. These types of bushing are not really meant for this and they are unable to prevent the engine from forcing the mount to slam into the frame.
So CP-e came up with a way to stress the bushing in only one direction. By remaking both pieces of the rear engine mount CP-e was able to mount the bushing vertically so that the pendulum effect of the engine is stretching or pushing in only one direction. This also increases the durability of the engine mount substantially. Orienting the bushing in a way that allows it to be compressed properly has allowed us to create a mount that provides a stiffer system without using an overly stiff bushing.
CP-e goes a step further using EPDM, a sort of rubber bushing. Urethane begins to fail at temperatures as low as 93°C and generally the mounts need a higher durometer rated bushing in order for the bushing to hold together. Our rear motor mount is a perfect example of when not to use urethane. The mount bolts directly to the transmission, transferring a large amount of heat to the mount and the bushing. EPDM holds up to this heat, and doesn’t begin to break down and fail. EPDM also carries a higher density than urethane, so the bushing can have a lower durometer rating while keeping a high reliability. Why is that good? Higher durometer ratings provide more vibrations through the vehicle and to the cabin, raising the NVH (noise, vibration, & harshness) value within the cabin.
