The life-time primary energy savings are lower compared to city buses, despite the high life-time performance. This is due to lower specific energy savings which amount for only about 25 % of the specific energy savings of the standard city bus.

Tab. 10: Overview of data for exemplification of average long distance bus

A life-time performance of 1.2 Mio. km is assumed for a typical long distance bus. This estimate already considers that some buses are exported to developing countries and achieve even higher life-time performances.
