Jimny JB64 and Jimny Sierra JB74 are not the same car.

The short answer

How do the Japanese Suzuki Jimny JB64W and Jimny Sierra JB74W differ?

Suzuki Japan's original fourth-generation specifications distinguish the JB64W kei Jimny's 658 cc R06A turbo engine, 1,475 mm width and 47 kW output from the JB74W Sierra's 1,460 cc K15B petrol engine, 1,645 mm width and 75 kW output. Their published wheelbase is 2,250 mm in both examples.

Applicable to: Japan-market 2018 fourth-generation Suzuki Jimny JB64W and Jimny Sierra JB74W launch editions. Not the five-door Jimny Nomade, export-market three-door configurations or a different model year.

02 / Before you use these values

Match the exact vehicle.

Check 1

Match the stamped Japanese chassis model code: JB64W is the 658 cc kei Jimny, whereas JB74W is the 1.5L Jimny Sierra.

Check 2

The listed dimensions are from Suzuki's Japanese 2018 original manufacturer editions. Modified bumpers, wheels or equipment affect fitment and real-world clearance.

Check 3

A shared fourth-generation platform and wheelbase do not mean engine oil, parts, tyres, gearing or ownership requirements are interchangeable.
