From its fit debut, the Tesla Model S powertrain has undergone numerous revisio that have improved its longevity, efficiency and power. The Model S can recoup the energy required to produce it in less than 10,000 miles. More than 60 kW of regenerative braking power is available from the drivetrain, which significantly lowe brake wear and energy coumption. Since there is an electronic power distribution between the two inductionmoto, there is no mechanical linkage between the front and back axles. As a matter of fact, accurate powertrain modeling and validation are paramount for critical design and control decisio of high performance electric vehicle.
