U.K.-based bus manufacturer Mellor Bus has recently launched a completely new range of battery-electric midsized buses under the Sigma brand name. First to market later in 2022 will be the 7-meter (23-ft) long Sigma 7 and 10-meter (32-ft 10-in) long Sigma 10. These two models will be followed by four others: Sigma 8, Sigma 9, Sigma 11 and Sigma 12.

The focus for the company has been to produce the Sigma range using light-weight construction methods, designed to allow for smaller battery capacities to consequently reduce energy consumption and shorten recharging times. Partner component manufacturers include CATL, Wabco, Webasto, ZF, Dana and Ventura. CATL supplies all the batteries for the range and the drive motors all are supplied by Dana. All Sigma models will carry full EU Type Approval.
