Mazda Motor Corp.’s CX-3 small crossover vehicle will be Japan’s first model to receive a new government fuel economy rating intended to reflect more realistic expectations, The Nikkei reports.
The new rating uses the so-called WLTC (worldwide harmonized light vehicle test cycle) that was co-developed three years ago by experts in Europe, India, South Korea and the U.S. and finalized in 2015. The lab-based test procedure will become mandatory in Japan in October 2018.
The new rating scheme will provide four types of mileage ratings for a vehicle: city, suburban, highway and combined. The ratings in Japan are expected to be between 10% and 20% lower than those generated by the current standard.
The system eventually will replace the New European Driving Cycle (NEDC) test that was lasted updated in 1997. Critics have complained that carmakers are “gaming” contemporary testing procedures to deliver fuel economy ratings that are significantly above real-world results.
