The Q50’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The CT4’s rear power window switches have to be held the entire time to close them fully.

If the windows are left open on the Q50 the driver can close them all at the outside door handle.

The driver of the CT4 can only close the windows from inside the vehicle, with the ignition on.

This allows the driver to concentrate on driving without constantly adjusting the wipers. The CT4’s standard manually variable intermittent wipers have to be constantly adjusted.

The Q50 Red Sport 400’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

The Q50 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the CT4.
