Weslake – The History
The company Weslake was created by Harry Weslake over 100 years ago. The historic UK brand Weslake has a rich heritage of novel powertrain design and manufacture with wins in many fields of motorsport including Formula 1, Le Mans 24-hour, offshore powerboat, motorcycle racing.
Weslake has built a reputation as a highly innovative propulsion design and manufacturing company. The brand was well known and respected throughout the UK , Europe and the Americas for being the motive force behind many high-profile victories including the Ford GT40 Le Mans 24 hour, world speedway and world power boat races.
Current History
Weslake have recently developed an Opposed Piston Uniflow powertrain that can operate on low fire risk bio and heavy fuels. It has excellent fuel efficiency and a good power to weight ratio.
The engine has immediate applications in both Marine and Aerospace propulsion, also future applications as a range extender Auxiliary Power Unit for Urban Air Mobility also lightweight portable generators and pumps for disaster relief.
Due to the limitation of battery storage capacity, electrification for marine and aerospace applications are limited. There is a very strong market requirement for heavy fuel marine and aviation propulsion for the foreseeable future.
