But “for drive-in, bumps, rumble strips, jagged edges, a cat’s eye, a sharp edge,” Warne explains, “you need a high-bandwidth rig or they all become like a sleeping policeman.”
You basically need something that can vibrate you at high frequencies and, just as importantly, with as little friction as possible and no bouncing or recoil when it stops so that everything is just as precise and as close to reality as possible.
The stiffness of the drive mechanism, the friction in the motors and even the weight of the base are all important, and the DMG system here gives a bandwidth of up to 100Hz – claimed to be 50% better than competitors.
Why is this so important? I get attached to find out, that’s when my greenness kicks in. Once the system is on, it kicks in again. I drive a few race tracks and it’s as immersive a system as I’ve ever felt.
The lower the latency, the faster you know how to handle changes. Sharp entries from curbs or oversteer feel wickedly sharp to me.
But what marks this system as special is more prosaic: riding a simulated test track without lateral forces and running over small surface imperfections.
There are 5mm steps in the asphalt, soft thuds in the headset and I feel through the seat as I go up and then down, the car rocks gently.
Luc Lacey, photographer, does not even see the rig move, to the point that an engineer goes over the helmet to ask me if it really works. He is.
