This year, Solaris will introduce a 15-meter Urbino version to the electric bus portfolio. The 15-meter version of the Urbino will also meet requirements of inter-city transport. The bus will be certified and offered with specs characteristic for class I vehicles – as a city bus, and for class II vehicles – as a bus for inter-city transport. The bus is propelled by the ZF CeTrax engine.

Solaris states in the press release that the decision to build a new bus was triggered not only by market interests, but also by the technical progress with regard to electric buses, and in terms of energy storage in particular. Energy storage in the new Urbino 15 LE electric will be covered by Solaris High Energy+ batteries. The first two pre-series vehicles will be fitted with 6 battery packs with a total capacity of over 470 kWh. Two will be roof-mounted, whereas four will be placed in the back of the bus. The drive unit of the tri-axle Urbino version will be the liquid-cooled, 300 kW central electric motor ZF CeTrax. The driveline will be moved to the second axle. In order to reduce the use of energy to a minimum, the manufacturer will implement SiC technology in the bus propulsion area.

The first two Solaris Urbino 15 LE electric vehicles will be made with Scandinavian operators in mind and complying with Bus Nordic standards and the so-called Scandinavian package. This entails, among others, special solutions ensuring thermal comfort in the vehicle, lighting or a type of passenger seats dedicated to transport between cities. Interestingly enough, the bus will be also equipped with sander which is solution familiar from the tram market mostly. The device enables movement even on the most icy or snowy of roads. In order to optimise the energy consumption, the Urbino 15 LE electric will be fitted with hybrid heating based on a heat pump. The new buses features MirrorEye and MobilEye Shield+. The design itself of the tri-axle bus of 15 meters is nothing new for the company. Solaris made its first tri-axle vehicles back in 1999 and to-date it has supplied nearly 1300 of these conventional diesel and CNG vehicles to customers. The low-entry electric buses will be available with a two-door (2-2-0) or three-door (2-2-1) outlay. The passenger seating capacity will amount to 55 persons for class II vehicles.
