SOR NB18 is derived from the SOR NB 12 rigid single-decker bus.
It is made of two rigid sections linked by a pivoting joint.
Engine and automatic transmission are located in the left rear corner of the bus.
Inside are used plastic Ster seats.
Rear axle is ZF brand, as well as medium axle, the front axle is of its own production with independent wheel suspension.
Only third C axle is propulsed, meaning that this articulated bus has pusher configuration.
Body of the vehicle is welded from steel-voltage profiles, flashings from the outside and interior are lined with plastic sheeting.
The floor of the bus is at a height of 360 mm above the ground.
On the right side of the bus are five doors (first are narrower than other doors).

The diesel hybrid bus NBH 18 is derived from NB 18, but it has hybrid drive (parallel hybrid drive unit from Allison allows accumulation of braking energy, which is then used for start-up by two electric motors built into Automatic transmission.

In Czech Republic are also produced trolleybuses SOR TNB 18 and Škoda 31Tr SOR in Škoda Transportation, which are based on SOR NB 18 bodies.
