According to The Asahi Shimbun, Japan’s transport ministry plans to compel auto manufacturers to install fuel-efficiency recording devices on all their new models to more accurately determine their mileage ratings amid increased public scepticism.
The transport ministry plans to revise the related regulations as early as next week and apply them for new car models as early as October 2023, officials said.
It comes amid heated industry competition over producing better fuel-economy cars, and as manufacturers find themselves under pressure to shift gears toward a low-carbon economy.
It also follows concerns expressed over large gaps between the mileage ratings reported by manufacturers in car catalogues and on websites compared to what the numbers actually are once the rubber hits the road.
And as automobile makers ramped up their efforts in recent years to compete over fuel economy, the automotive industry became plagued by scandal over fudged numbers.
