Japan proposes mandate for 24.1% improvement in average fuel economy by 2020

Integrity Exports. Japan’s Ministry of Economy, Trade and Industry and Ministry of Land, Infrastructure, Transport and Tourism announced a draft of new fuel economy standards for cars that will require improvements of 24.1% over 2009 levels by 2020. The proposal is now open for public comment.

The proposed new overall average target for 2020 is 20.3 km per liter [47.8 mpg US; 4.93 L/100km]. Passenger cars will be divided into 15 sub-divisions by weight with the range of target fuel economy levels varying from 10.6 km per liter to 24.6 km per liter [24.9 to 57.9 mpg US; 9.43 to 4.07 L/100km].

This new 2020 target is an improvement of 19.6% over the current 2015 targeted fuel economy figures, and as such it seems that this will require an acceleration in technological innovation to meet these standards.

Under japan’s current scheme, automakers must meet varying standards in 16 vehicle weight classes. The new rule would be based on the average fuel economy of all the vehicles an automaker sells—i.e., in line with the US and European approaches.

This can be achieved with more HEVs, PHEVs and BEVs.

Lighter-smaller vehicles, improved ICE and batteries will also help to reach this goal and more.
