Cadillac outdoes Ferrari?
In a recent commercial Cadillac boasts about an innovative suspension technology in its CTS-V Coupe they claim Ferrari borrowed in its own 458 Italia. This technology, known as “magnetorheological shock absorption “, essentially works via a computer chip that continuously adjusts the magnetic field within the shocks to manipulate the viscosity, or ease of flow, of a fluid containing tiny iron particles.
When the magnetic field is applied the iron bits will align, and the fluid, usually an oil, will flow less freely. When the magnetic field’s intensity decreases the opposite occurs, causing the suspension to become less rigid.
The computer chip, also known an an electronic control unit (ECU), is smart enough to detect the bumps in the road and signal the appropriate magnetic field intensity causing the fluid filled shocks to stabilize the car’s suspension. What’s even more impressive is that these calculations are performed nearly continuously – every millisecond – and are isolated for each tire, creating a smoother driving experience.
The only downside to this system is cost, but it is well worth it to a car enthusiast. Given the seamless mechanics of this suspension, it is easy to understand why Chevy has adapted it to the Corvette, Audi to the TT and R8, and yes, Ferrari to a few of its models.
