DBW
Drive-by-Wire. This is a feature that most new cars have to run the engine. Normally when you step on the gas, a cable is pulled and opens the throttle. In a Drive-by-Wire system, the throttle cable is eliminated and the process is done electronically.
Toyota says that their new DBW system actually improves throttle response!
