This report covers passenger vehicles sold in Japan as of the end of Reiwa 4 (December 2022). 2. Why are several Kei car models tied in fuel economy? Japanese automakers frequently share platforms under OEM agreements. For instance, the Mazda Carol is manufactured by Suzuki, sharing the 0.657L engine and 27.7 km/L rating of the Suzuki Alto. 3. Are WLTC figures realistic for overseas driving conditions? Yes. The WLTC test measures city, suburban, and highway speeds, making it a reliable standard for real-world commuting. 4.
