Solaris introduces an addition to the product portfolio with the Solaris Urbino mild hybrid. “The Solaris Urbino mild hybrid is a novelty in our offer, though it is one based on the perfected solution of the latest generation. With this extension of our portfolio, we offer our clients a choice between completely zero-emission or low-emission vehicles,” stressed Michał Pikuła, Bus Development Director, Solaris Bus & Coach.

Solaris is not new to hybrid buses. The first Urbino hybrid was displayed in 2006. The mild hybrid is a novel solution. It is the response to needs of operators and carriers offering services of public transport for innovative urban transport vehicles which minimise the impact of such transport on the natural environment, while at the same time allowing to generate considerable savings and to reduce fuel consumption.

Commonly known as mild hybrid on the market, this solution marks a natural evolution of the recuperation technology in buses - a technology using energy generated during braking. Thanks to mild hybrid solution, vehicles are more environmental friendly and going far beyond the Euro 6 strict emissions standards for diesel engines. Implemented in the latest item in the bus portfolio of Solaris, the system is based on three crucial elements: an electric machine, an energy storage system and a driver for the structure monitoring the operation of the system. When braking energy is recuperated and recharges the energy storage with the maximum available power. The capacity of the energy storage tank has been chosen so as to facilitate the recuperation of energy when braking from the speed of ca. 60 kph downwards. When the storage unit is partially or fully recharged, during the acceleration process, the electric machine acts as an electric engine supporting the operation of the diesel engine resulting in reducing fuel consumption.
