Users will be able to choose from among three energy modules that offer driving ranges of 150, 300 or 400 kilometers (93, 186 or 249 miles). Depending on their needs, drivers will have the option of changing from one module to another on the same vehicle whenever necessary. In this way, the partners say, WILL’s driving range can evolve to suit each user’s needs, at any time.
Det ska också komma en Roadster med Michelin's hjulmotorer. Venturi Volage. 45 kWh batteri på 350 kg (Li-Polymer). Ska klara 1500 cykler. 0-100 på under 5s, räckvidd på 32 mil , toppfart ca 150 km/h.
Michelin har också startat ett samarbete med en kinesisk tillverkare:

Already, the two companies have a working prototype built atop a Lifan 520 sedan that can reach 87 mph and go for up to 81 miles before needing a recharge of its lithium ion batteries. The dynamic duo believes it can have the system ready for OEMs by the end of the year.

Improved driving behavior – very good for small cars
Improved efficiency in partial load operation, thus less power
consumption
Small motors
Modularization of components 1, 2 or 4 motors per car
Freedom of design; no differential; less mechanical components
Smaller power to be handled
High quantities; cost effectiveness
Safety is mandatory
System competence mandatory for synergies
New power and control electronics including MEMS sensors make
such solutions feasible
