The Mellor Sigma is a battery electric single-deck bus manufactured by Wisdom Motor in China and sold in Europe by Mellor Coachcraft between 2021 and 2024.[1] It was available in various lengths, from 6.99 – 13.50 metres, with the shortest being marketed as the Mellor Sigma 7,[2] and the longest as the Mellor Sigma 13.[2]
The Sigma was created as a zero-emission single deck vehicle, marketed as improving "demand for cleaner solutions to public transport".[3] Mellor claim that there is a weight saving across all models compared to competitor vehicles, with capacities between 30 and 80 passengers depending on the vehicle size.[4]
Mellor initially launched the Sigma with the Sigma 7 and Sigma 10 models,[5] with the Sigma 7 being a single door model and the Sigma 10 being a dual door model. The Sigma 7 debuted at ITT Hub,[6] while the 9.4 metres (31 ft) Sigma 9 later debuted at Busworld Europe 2023 in Brussels. A 13.5 metres (44 ft) variant known as the Sigma 13 was also announced at the event in October 2023.[7]
As of May 2024, Mellor Coachcraft had ceased to market the Sigma bus range.[1]
Concurrent with the product and sales team alignment has been confirmation that the Sigma battery-electric bus range no longer forms part of the Mellor range. Previously, it was built by Wisdom Motor and badged as a Mellor product.
