The Ministry of Construction is seeking feedback from relevant agencies on a proposal to make fuel efficiency of 4.83 liters per 100 kilometers mandatory for all passenger cars by that year.

This means EVs will remain outside the purview of this regulation.
Those who fail to meet the cut can buy fuel consumption credits from those who do, similar to the carbon credit trading system used globally.
Manufacturers are advised to upgrade their technologies, eliminate fuel-guzzling vehicles and increase the number of fuel-efficient models in their lineups.
If they fail to meet the minimum standards after three years, they will have to stop production or importation until an appropriate alternative plan is in place.
VAMA, an auto industry group made up of 17 manufacturers, considers the proposed threshold “too strict.”
It said 96% of gasoline vehicles and 14% of hybrid models would fail to meet these standards, it said.
For instance Toyota’s best-selling sedan, the Vios, requires 5.08 liters per 100 km for its most fuel-efficient iteration variant.
On the other hand, Toyota’s Yaris Cross Hybrid consumes 3.56-3.8 liters per 100 km.
VAMA said to meet the target and maintain sales volumes, the industry would need to increase the share of electrified vehicles by almost 10 times over the next five years.
This is not feasible due to the limited charging infrastructure and lack of consumer familiarity with electric vehicles, it added.
It suggested a different target: 6.7 liters per 100 km in 2027, 6.5 in 2028, 6.3 in 2029, and 6 in 2030.
For this road map, manufacturers would need to reduce gasoline vehicle production by 34% and increase EV sales by at least 366%, a feasible option, it added.
