When it comes to electric vehicles, efficiency is money.
Even a 2 or 3 percent gain in efficiency could save automakers hundreds of dollars per EV — edging them closer to cost parity with internal combustion vehicles and, more importantly, improved profitability.
When the auto industry trains its product development guns on a component, that item usually gets smaller, lighter, simpler, more powerful and more efficient. Oftentimes a component comes through that transformation costing less as engineers find ways to reduce precious metal content and other raw materials and to improve manufacturing efficiency.
That is what is happening today to the electric motor, which is just starting what will likely be a very long journey in the automobile.
"It's all about losses in the motor, and right now we are only at the beginning of optimizing that and the control of the motor," General Motors President Mark Reuss told Automotive News.
