When a drive range of a transmission is selected from a neutral range at a high engine racing speed, a racing start signal is produced. In response to the racing start signal, the electromagnetic clutch is engaged at a higher engaging rate than an ordinary engaging speed.

A predetermined control on an engine, i.e., a fuel-cut operation, is executed after an accelerator has been released under predetermined conditions when vehicle speed is higher than a fuel-cut vehicle speed value and engine speed is higher than or equal to a fuel-cut engine speed value. In an automatic transmission drivingly connected to the engine via a torque converter, a gear shift is initiated...
