The 4-series was superseded in 2006 by the new Euro IV compliant bus and coach range consisting of the K-series, N-series and F-series.

[3] In November 1999,[4] Scania presented a new range of Euro III compliant truck engines, which soon became available on the buses too.

They were mainly produced in São Bernardo do Campo, Brazil and Tucumán, Argentina[5] for the Latin American and African market.

The K94IB, K114IB and K124IB were the standard coach and intercity bus chassis with a rigid front axle.

Westbus (Sydney), Australia received a batch of Volgren CR228L bodied K94UB with Brazilian-made chassis.

The L94-series was a longitudinal inclined rear-engined simple coach, intercity and city bus series, and was a direct replacement for the L113.

The L94IB was the basis for the first generation of the OmniLine integral intercity bus available in some left-hand drive markets.

It was available from around 2001 as an alternative to the full low-floor N94UA, and was also the basis for the first generation of the articulated version of the OmniLink integral citybus.

The L94UB was the versatile citybus chassis when a full low floor was not required, as it like the L94UA was a low-entry configuration.

The N94UA (N94UA6x2/2EB) articulated chassis had a low floor throughout the length of the bus, compared to the L94UA which had a step up.

The N94UB (N94UB4x2EB) rigid two-axle chassis was first introduced as the basis for the integral OmniCity citbus in 1996, but was also available for bodywork by other manufacturers from 1997.

Having a full low floor, it did not sell as well as the L94UB in the Nordic countries, where the low-entry alternative was more popular.
