DYNAMICS & CONTROL
In our cars(Electronic Stability Program)
• Curving or under unstable conditions
breaking is applied selectively and independently
to each wheel. ...
Mercedes A: ESP
• 4 wheel automatic power control
Dynamic distribution of torque between front
and back wheel axis ...
Audi: Quattro• Fuel saving by automatic control of
valves opening
Honda Civic: VTEC
Well, let’s say that way !!!
