[QUOTE="John_Smith, post: 411300, member: 15372"] Ford Control Blade™ Suspension Control blade is basically an evolution of trailing-arm suspension. The purpose of Control Blade suspension is two-fold. First they wanted to separate the various suspension functions from each other - isolating the handling components from the ride qualiy components. With the springs and shock absorbers being mounted separately, Ford have managed to optimise the function of these components. It's similar in concept to what BMW did with the telelever front suspension on motorbikes (separating braking from suspension forces) only in the Ford system, it separates the springing support of the suspension from the shock reducing functions of the shock absorbers. Secondly it increases the interior space available in the vehicle. Most suspension systems used in daily drivers have strut towers in the rear of the vehicle - those bumps either side of the boot (trunk). Ford wanted to give more space in the back and needed to find a good way to remove or reduce the size of those towers. With Control Blade™, because the shock absorbers are separated from the springs, it opened up a lot more design flexibility. Ford used a trailing-arm type suspension so that they didn't have swingarms up under the wheel arches and the springs were shortened and moved inboard and underneath. In one variation, the shock absorbers still sit vertically but the space they take up now is hugely reduced because they no longer have the coil springs around the outside. In the second variation the shock absorber is a subminiature unit mounted inboard of the springs underneath the vehicle. The control blades themselves are basically the trailing arms which give lateral support and provide the vertical pivot point for the entire unit. The Ford spiel says this about Control Blade™: "It has the key function of promoting ride and reducing road noise transmission, while providing the freedom to let the lateral links define toe and camber by absorbing any rearward forces and allowing the rest of the suspension to do it's job uninterrupted. Effectively isolating the handling components of the new IRS from the road noise and impact harshness components of the suspension.". In English? It means better handling and less road noise.
