The fourth-generation Coaster incorporates many safety features as standard including air-bags for the driver and front passenger, Vehicle Stability Control (VSC), a ringed frame body for increased roll-over protection, pre-tensioners for the seat belts, and force limiters which reduce the pressure on the passenger’s chest in the event of a collision.

The height was increased by 60 mm (2.4 in), the width was increased by 40 mm (1.6 in) and the window height was increased by 50 mm (2.0 in) over the outgoing model. The door step was also lengthened by 65 mm (2.6 in) for easier entry and exit. The body was designed in a square shape for more spacious seating space. The windshield was widened for increased outward visibility. The Coaster is available in three configurations; the standard wheelbase configuration can seat 25 passengers, the long-wheelbase configuration can either seat 24 or 29 passengers while a school bus configuration can seat 3 adults and 49 children. The school bus configuration does not have a front passenger seat.
