I'm slightly obsessed with vehicle dynamics at the moment.

The other day I learned that the latest Porsche 911 GT3 has magneto-rheological engine mounts. They're a simple enough idea, but one that's probably a right royal pain in the backside to tune properly. The theory is that they're slack when one wants to dampen noise and vibration (say during stop/start or unhurried gearchanges), yet they're stiffened at the right times so the engine's mass doesn't affect body movements (during hard cornering, acceleration or braking, for example).

I've been thinking a bit more about this recently, after a conversation with Matt Becker, Lotus's engineer in charge of the way the Evora drives.
