Jimny vs Jimny Sierra: What’s Actually Different?

Buying & Ownership

One badge, three meanings. In Japan the Jimny and the Jimny Sierra are two different vehicles. In Australia the Sierra name carries four decades of history. Here is the full decoder, the spec by spec comparison and a straight answer on which one you should actually buy.

This question lands in our inbox more than almost any other, and the confusion is understandable. The same word means different things depending on where you live and which decade you grew up in. I have owned and driven both modern versions and spent enough time around the classics to give you the complete picture. The short answer sits in the card below. The detail, including the numbers Suzuki publishes and the import rules most articles skip, follows underneath.

One badge, three meanings

Suzuki has recycled the Sierra name across markets and generations, which is why a search for this comparison returns three different conversations. The JDM import specialists at JDMbuysell put it neatly in their JB64 guide, calling the two modern cars the same chassis with a different engine, wider fenders and a different tax bracket. That tax point is the whole reason the split exists. Japan rewards cars that stay inside the kei class limits with sharply lower tax and insurance, so Suzuki builds a narrow 658cc Jimny for home and a wide 1.5 litre Sierra for everyone else. Here is the decoder.

Where and when	What the name means	Chassis codes
Japan, 2018 to today	Jimny is the kei car. Jimny Sierra is the wide body 1.5	JB64 / JB74
Export markets, 2018 to today	The Sierra is sold as simply Jimny in Australia, the UK, South Africa, India and beyond	JB74
Australia, 1981 to 1998	Suzuki Sierra was the local name for the SJ410 and SJ413, the truck Americans knew as the Samurai	SJ410 / SJ413
Australia, 2008 to 2018	The third generation Jimny wore a Jimny Sierra badge in its later years	JB43
Japan, 1998 to 2018	Previous split. Jimny was the kei JB23, Jimny Sierra and Jimny Wide were the 1.3 litre wide body	JB23 / JB43

If the generations themselves are the part you want to untangle, our generations guide walks through every chassis from the LJ10 to today.

JB64 vs JB74: the numbers side by side

These are the current production cars as Suzuki specifies them for Japan, with export figures noted where they differ. Read the table and the pattern jumps out. Everything that defines a Jimny is identical. Everything shaped by regulation is different.

Specification	Jimny (JB64, kei)	Jimny Sierra (JB74)
Engine	R06A 658cc turbocharged 3 cylinder	K15B 1,462cc naturally aspirated 4 cylinder
Power	47 kW (64 PS)	75 kW (102 PS)
Torque	96 Nm	130 Nm
Length	3,395 mm including the spare	3,550 mm body, about 3,645 mm with the tailgate spare
Width	1,475 mm	1,645 mm with flared arches
Kerb weight	about 1,040 kg	about 1,090 kg
Standard tyres	175/80R16	195/80R15
Drivetrain	Identical. Ladder frame, 3 link coil sprung rigid axles, ALLGRIP PRO part time 4WD with low range
Tax class	Kei, yellow plates, reduced tax and insurance	Standard registration
Where sold new	Japan only	Worldwide, badged Jimny outside Japan
Japan price, 2026 model year	about ¥1.92 to ¥2.16 million	about ¥2.27 to ¥2.39 million

Both cars received the same 2026 model year safety upgrade in Japan. Suzuki replaced the old monocular camera and laser setup with a stereo camera and millimetre wave radar system, and automatic versions gained adaptive cruise control, changes detailed by Rushlane when the update landed in January 2026. Prices rose with it. The five door Nomade, which Japan buys through a lottery after orders reopened on 30 January 2026, now lists at ¥2,926,000, and reported waiting times stretch toward four years. If the five door layout is what you are weighing, our 3 door vs 5 door guide covers that decision properly.

How differently do they drive?

Less than the spec sheet suggests off road, more than you would expect on it. The kei car’s little turbo triple is a willing thing that asks you to work the gearbox and keep it spinning. Around town and on tight trails it feels perfectly matched to the car, and the narrow body threads gaps even the Sierra brushes. Push it to open road speeds and it gets busy. The 47 kW ceiling is a regulation, not an engineering choice, and you feel that honesty at 110 km/h.

The Sierra’s naturally aspirated 1.5 changes the character. It lugs from low revs, holds a cruise with less effort and gives you the wider track that calms the car in crosswinds and on gravel. It is the version engineered for countries with long distances and 120 km/h limits, which is exactly why export markets get it. In the hard stuff the two are near twins. The geometry is almost identical, the low range reduction is the same, and both run the same ALLGRIP PRO system. One accuracy note we repeat in every guide because it matters. ALLGRIP PRO is a part time system with no centre differential, so 4H is for loose surfaces only, never dry tarmac.

The kei Jimny is the Japan optimised Jimny. The Sierra is the same idea sized for the rest of the world. Neither is the lesser car. They answer different regulations.

The classic question: old Suzuki Sierra vs modern Jimny

For many Australians this comparison means something else entirely, the leaf sprung SJ era Sierra against the modern coil sprung Jimny, and it deserves a straight answer too. The old Sierra is lighter, mechanically simple and famously easy to modify, which is why Australian 4WD specialists still rate it as a dedicated trail toy with stronger transfer gearing and a huge budget aftermarket. The modern Jimny answers with fuel injection reliability, coil spring comfort, real crash structure and electronics that make it a genuine daily driver. Our honest take after time in both. Buy the classic as a second vehicle project with your eyes open on rust and parts age. Buy the modern car if it has to start every morning and carry your family. Whichever way you lean, run our pre purchase checklist before money moves.

Prices, availability and the import question

Outside Japan you buy the Sierra by default. In Australia the JB74 range opens at A$31,990 before on road costs in updated 2026 form, per carsales’ launch review, and our Australian buying guide tracks the grades and waiting lists in detail. The interesting play for enthusiasts is importing the kei car, because the JB64 was never sold new in Australia and that is precisely what makes it eligible.

At the time of writing the JB64W appears on Australia’s SEVS register under the environmental criterion, with import specialists such as Carbarn citing approval SEV-000654 covering builds from May 2018 to February 2025. The process runs through a ROVER import approval before the car ships, compliance by a Registered Automotive Workshop on arrival, zero customs duty on Japanese built vehicles under the trade agreement and 10 percent GST, as laid out in JDMbuysell’s Australian import guide. Rules and register entries change, so verify the current SEVS listing and get your approval in writing before you commit a cent. American readers have no modern pathway at all. Under the 25 year rule the JB64 and JB74 only become importable to the US from 2043. South African readers should treat the kei as off the table for road registration in most cases, since used import permits are tightly restricted, and the locally sold JB74 remains the answer. Whichever route you take, budget with our running costs guide open in a second tab.

Which one should you buy?

My own answer, having run the sums both ways. The Sierra in export trim is the rational pick for almost everyone reading this outside Japan, and it is the car we compare against the big trucks in our Jimny vs larger 4x4s guide. The kei JB64 is the connoisseur’s Jimny, and if one comes up compliant and clean, it is one of the most charming small 4x4s money can buy.
