Since the driver may be responsible for more than 100 passengers it’s of the utmost importance to engineer our bus chassis to provide complete vehicle control, with a sense of consistent response and predictable vehicle behaviour.  We make certain that all our vehicles offer good manoeuvrability at low speeds and good directional stability at high speeds. In order to obtain these objectives, our chassis components are carefully selected and tuned in order to fit each customer application.  

ESP (Electronic Stability Program)
This advanced system is designed to minimise the risk of skidding or rollover resulting from driver error, sudden emergencies or unexpected hazardous road surfaces. The objective is to help the driver regain full control as soon as possible in difficult conditions.

Directional Stability
When a bus or coach is driven over the road it’s exposed to various disturbances, such as crosswinds and uneven surfaces that affect the path of the vehicle. This can lead to fatigue in cases where the driver needs to continually compensate. That’s why we engineer our buses and coaches to provide the driver with accurate feedback and an agile and predictable response to driver inputs. We achieve this with a steering system that provides excellent sensitivity and an optimised chassis setting. In addition, Scania is taking part in a research effort to better address issues of directional stability during larger disturbances and thus further improve the crosswind stability of future buses and coaches. 

Tilt testing
All buses built on Scania chassis comply with tilt test regulations. The tilt tests can be performed either as physical tests or by means of calculations and modelling that simulate high lateral accelerations. For bodybuilders, Scania can easily provide information about how each vehicle will perform in these tests and assure that the completed bus or coach will be safe regarding tilting forces. In order to further improve vehicle stability, ESP significantly reduces the risk of overturning.
