1. Introduction With the advent of electric mobility, a key question for new builds and retrofitting is whether a manual transmission (MT) or single-speed transmission would result in the most-efficient drivetrain. This paper answers that question using a drivetrain design of a retrofitted vehicle from Sub-Saharan Africa [1]. Global sectors are racing to reduce carbon emissions and avoid global temperatures rising by 1.5 °C before 2030 [2].

1. Introduction “The vehicle capital cost is considered a key barrier to uptake [of electric vehicles in sub-Saharan Africa]. Therefore, affordable vehicles must be designed and manufactured to lower vehicle capital costs. This could be achieved through local manufacturing of SSA-specific EVs.” and “Alternatively, retrofitting vehicles to be electric could lower prices even further and be a more widely achievable option.” —Collett et al. in Energy Strategy Reviews [1].
