New Suzuki Swift: hybrid, gearbox and drivetrain change fuel economy.

The short answer

How does the Japan-market 2024 Suzuki Swift mild hybrid compare with the gasoline XG?

Suzuki's 2023 launch of the 2024-generation Japanese Swift lists 25.4 km/L WLTC for the HYBRID MX 2WD manual, 24.5 for HYBRID MX/MZ 2WD CVT, 22.7 for mild-hybrid 4WD CVT, and 23.4 for the gasoline XG 2WD CVT. The Japanese grade specification lists a nominal 37-litre tank for these versions.

Applicable to: Japan-market late-2023 launch of the 2024-generation Swift Z12E 1.197L: XG and mild-hybrid HYBRID MX/MZ. Not Suzuki Swift Sport, Indian Maruti Swift, overseas WLTP or different generations.

02 / Before you use these values

Match the exact vehicle.

Check 1

Confirm Japanese ZCEDS/ZDEDS mild-hybrid or ZCDDS/ZDDDS XG model code and actual transmission before comparing mileage figures.

Check 2

WLTC Japanese km/L is a regulated cycle, not achieved city fuel economy or guaranteed driving distance. Tank size cannot be multiplied by WLTC to promise owner range.

Check 3

Maruti Suzuki Swift sold in India and Swift Sport use separate local engines, equipment and regulations. Do not transfer Japanese grade figures.

03 / Verification and next answers

Where the numbers came from

Suzuki Motor Corporation's December 2023 Japanese Swift launch release lists each trim/drive/transmission combination's WLTC and JC08 ratings; the separate Suzuki Japan official Swift grade table corroborates the nominal 37 L fuel tank and Z12E engines.
