TOKYO -- Japan will require automakers to raise fleetwide fuel efficiency more than 30% by fiscal 2030, an ambitious target designed to help the country catch up with the shifts toward zero-emissions vehicles in Europe and China.
The new standards released Monday call for average fuel economy of 25.4 km per liter of gasoline across total vehicle sales for a given company, up 32% from the fiscal 2016 performance. Japan already mandates a 24% improvement by fiscal 2020 from 11 years prior. The relevant rules will be revised by March.
