Prototypes of a novel, multi-speed transmission for electric vehicles (EVs) have begun on-road testing with a European vehicle manufacturer. Designed and manufactured by Italian drivetrain specialist Oerlikon Graziano with British control systems specialist Vocis, the simple, elegant concept will increase vehicle range or allow reduced battery pack size, as well as providing improved low-speed pull away and higher-speed cruising.

Transmission engineering and control specialist Vocis will give its novel twin speed electric vehicle (EV) transmission its first public demonstration at LCV2011 (the Low Carbon Vehicle show) on September 7-8, at Rockingham Motor Speedway. Technical specialists from the company will be on hand to provide an insight into the technology and the efficiency, performance and range benefits it offers for the next generation of EVs.
