Ward has announced yesterday that Nissan Leaf's power system is included on its prestigious '10 Best Engines' list for 2011. As you can imagine, it is the first time that a power system which doesn't have an engine is included.
The Leaf features a high-response 80kW AC synchronous motor powered by a 24 kWh lithium-ion battery manufactured at the Automotive Energy Supply Corporation (AESC) operation in Zama, Japan, which is a joint-venture of Nissan Motor Co., Ltd. and NEC Corporation. Both motor and inverter have been developed by Nissan, and the power system generates 107 horsepower and 207 lb-ft of torque. The power is transferred to the wheels through a single-speed reduction gear.
