Arcimoto, Inc. unveiled the 4th Generation Prototype of the Mean Lean Machine, an all-electric tilting E-trike, at a team event Friday afternoon. Arcimoto also demonstrated the beta version of their upcoming Torque Vectoring software upgrade. A full recap of the day's events can be found in latest Weekend Stakeholder Update.

The prototype, which represents the ‘Cybertrike Edition' of the Mean Lean Machine product family, will be on display through the weekend at the Riverfront Fan Festival for the World Athletics Championship in Eugene, Oregon. According to remarks made at the unveiling, the new iteration of the Mean Lean Machine features major improvements in the suspension, the first packaging study of Arcimoto's MicroFutureDrive, and carbon-fiber wheels. Arcimoto intends to build copies of this prototype iteration for on-road marketing and testing purposes.

Also announced and demonstrated at the event was the beta version of Arcimoto's Torque Vectoring software. Developed with Stafl Systems, the Torque Vectoring software upgrade is intended to improve traction and make steering at low speeds much easier. Arcimoto aims to roll the software upgrade out to existing customers before the end of the year.
