OxDrive joint venture unveils self-contained e-hub for farm vehicles

OEMs developing small EVs for agricultural applications, including those intended to have autonomous capabilities, want to focus their efforts on the core agricultural functions and the autonomy (writes Peter Donaldson). Typically, however, they are faced with specifying the driveline, sourcing components and integrating them, says Chris Horton of OxDrive, a joint venture between Performance Projects […]
