Why the Honda Stepwgn RP5 Became an Australian Import Favourite

For buyers who prioritise easy access, low step-in height, and manageable size, Australia’s new-car showrooms leave limited choice, which is why the Honda Stepwgn RP5 continues to attract import attention. Back in September 2017 facelift mattered because that minor model change was when Honda added the Sport Hybrid i-MMD two-motor hybrid to the Step WGN SPADA lineup, refreshed the SPADA exterior, and pushed Honda SENSING to standard across the Step WGN range in Japan. That’s why the Honda Stepwgn RP5 “Spada Hybrid” is the one most Australians chase: it’s the hybrid and the safer, later-spec version.

And then there’s the Waku Waku Gate(Split tailgate). On the 5th-gen Stepwgn (RP1–RP5), Honda’s split tailgate can open as a normal liftgate or as a side-opening “door” section for tight parking, third-row access, and quick loading. For Australian life, narrow garages, school drop-offs, prams, sports gear, it’s not a gimmick. It’s a real usability advantage, and it’s a big reason the RP5 remains popular even after the newer shape arrived.

Model Naming Explained: Step WGN, Stepwgn, and RP5 Listings

Step WGN is Honda’s official styling, used across many Japanese-market materials and press releases.
Stepwgn or STEPWGN is the most common romanised form in export listings and overseas dealer inventories.
Stepwagon is an informal, phonetic version that appears on some seller sites and catalogue databases.

For Australian buyers, the distinction isn’t just cosmetic. It affects search results. Limiting searches to “Stepwgn” can mean missing vehicles listed under “Step WGN” or the informal “Stepwagon”, particularly on Japanese auction and export platforms.

As for how the Honda Stepwgn RP5 appears in listings, the hybrid is most often identified as 6AA-RP5, which is the model-code format used in many Japanese auction and export records. You may also see trim descriptions such as e: HEV SPADA G, SPADA Hybrid G EX, or references to Honda SENSING, depending on how the seller formats the listing.

Variant history timeline: where the Honda Stepwgn RP5 fits

The fifth-generation Honda Stepwgn (RP1–RP5) was launched in Japan in 2015 and set the template that made the model popular with import buyers. It introduced the 1.5-litre VTEC Turbo petrol engine and, more notably, the distinctive Waku Waku Gate split tailgate – a feature that would become a defining part of the Stepwgn’s identity.

Pre-facelift (2015 to August 2017)
Early RP-series Stepwgns are dominated by petrol variants, covering RP1 through RP4 with the 1.5-litre turbo engine. While a hybrid option existed in limited form, it wasn’t yet the mainstream choice and lacked the later safety and equipment updates that Australian buyers tend to prioritise.

Facelift / minor model change (from September 2017)
Honda began sales of the refreshed Step WGN on 29 September 2017, and this update is the critical turning point. The facelift brought the Sport Hybrid i-MMD two-motor system into the SPADA line-up, along with a refreshed SPADA exterior, LED lighting and aero revisions, and broader standardisation of Honda SENSING safety technology. This is where the RP5 sits – the facelift-era hybrid family that most Australian buyers target.

Sixth generation (RP6–RP8, unveiled January 2022)
The all-new Stepwgn arrived in early 2022 with a redesigned body and a revised line-up structure (Air, Spada and Premium Line, depending on market). Importantly, Honda dropped the Waku Waku Gate in favour of a conventional tailgate. While the newer models can be excellent in their own right, they represent a different ownership proposition. For buyers drawn to the split tailgate’s everyday usability, the RP5 is effectively the last of that idea.

Sport Hybrid i-MMD on the Honda Stepwgn RP5

Sport Hybrid i-MMD (intelligent Multi-Mode Drive) is Honda’s hybrid powertrain system, not a vehicle variant or trim level. It is the hybrid drivetrain technology fitted to RP5 models. The big difference with the Honda Stepwgn RP5 Spada Hybrid is that it doesn’t behave like most “engine-first” hybrids.

Honda’s Sport Hybrid i-MMD is designed so the electric motor does most of the driving most of the time, and the petrol engine often works more like a power source than the thing that directly turns the wheels. Honda describes the Step WGN SPADA hybrid as using a two-motor i-MMD system.

No normal gearbox 

There isn’t a traditional multi-gear automatic transmission in the usual sense. Instead, i-MMD uses:

• the electric motors for variable-speed driving, and

• a lock-up clutch + a fixed gear connection for efficient highway cruising when it makes sense.

The 3 drive modes of Honda’s i-MMD Switch

Honda’s i-MMD switches between three main modes automatically.

EV Drive

The Stepwgn is driven by the traction motor using energy from the battery.

The petrol engine is off.

This is most common at low speeds, creeping traffic, carparks, and gentle acceleration.

(Important nuance: EV Drive can be frequent in city use, but it’s not “EV-only all day” the engine will start when the battery or power demand requires it.)

Hybrid Drive

The petrol engine runs, but mainly to spin the generator motor.

The generator produces electricity to power the drive motor (and/or top up the battery).

In this mode, the engine is not mechanically connected to the wheels; it’s basically generating electricity so the electric motor can keep driving.

Honda describes Hybrid Drive exactly in this “engine powers generator” way.

Engine Drive 

At steady highway speeds, it can be more efficient to connect the petrol engine directly to the wheels.

A lock-up clutch engages, so the engine drives the wheels through a fixed gear.

The system can still use the motor for assist and can still charge, but the key point is: the engine is now mechanically driving the car.

Honda Stepwgn RP5 LFA1 Hybrid Engine Explained

The petrol engine used in the Honda Stepwgn RP5 Spada Hybrid is a 2.0-litre, four-cylinder DOHC i-VTEC engine that is designed to work as part of Honda’s Sport Hybrid i-MMD system.

Unlike a normal petrol engine that is tuned mainly for power, this engine runs on the Atkinson cycle. This means the intake valves stay open slightly longer during the compression stroke. 

All RP5 Stepwgn hybrids use Honda’s Sport Hybrid i-MMD (Intelligent Multi-Mode Drive) system. This is a two-motor hybrid, not a conventional petrol-engine-first setup.

Main components

Petrol engine:

2.0-litre, 4-cylinder DOHC i-VTEC

Atkinson-cycle design

Engine code commonly shown as LFA / LFA1

Electric motors:

One traction motor (drives the wheels)

One generator motor (produces electricity from the engine)

Battery:

Lithium-ion battery pack

Drivetrain:

Front-wheel drive only (no 4WD option on RP5 hybrids)

Transmission type:

Honda i-MMD e-CVT (no belts, pulleys, or stepped gears)

The result is:

• better fuel efficiency,

• lower pumping losses,

• and less focus on raw power.

In simple terms, the engine is designed to be efficient and smooth, not sporty on its own. Most of the time, it supports the electric motors rather than directly driving the wheels.

What these numbers actually mean when driving

Although the petrol engine’s torque figure looks modest on paper, that’s not a problem in real use.

The Honda Stepwgn RP5 feels stronger than expected because:

• The electric motor provides full torque from zero RPM, and

• The petrol engine doesn’t need to rev hard to move the car.

This removes the common weakness of naturally aspirated petrol people-movers, which often feel slow pulling away from lights or when loaded with passengers.

Here is a deep dive into the Honda Stepwgn RP5 (Spada Hybrid) variants

Honda Stepwgn RP5 Spada Hybrid B

The Honda Stepwgn RP5 Spada Hybrid B is the entry-grade variant and is best suited to fleet buyers, camper converters, or budget-conscious families who care more about the hybrid drivetrain and spacious body than extra luxury features. It delivers the main strengths of the RP5 platform, including hybrid efficiency, cabin practicality, and family-friendly packaging, but in a simpler and more functional specification. On the outside, the B grade usually comes with standard 16-inch silver alloy wheels and LED low-beam headlights, so it still looks modern enough, but the finer details are more basic. Fog lights are often halogen with a yellowish tone, or may be missing entirely, depending on the option pack. Many examples also come with only a single power sliding door on the passenger side, while the driver-side rear sliding door is manual.

Inside, the B grade is focused on durability rather than a premium feel. The seats are usually finished in basic cloth with no leather-style trim, and the steering wheel is urethane rather than leather-wrapped, giving it a smoother, harder plastic feel in the hand. Heated front seats are generally not included, which is one of the clearest differences from the higher grades. Climate control is still decent, with dual-zone automatic climate control for the front occupants, but rear passengers usually only get fan-speed adjustment rather than their own temperature control. The easiest way to identify a B grade is to look at the steering wheel. If it looks plain, smooth, and plastic rather than stitched leather, it is usually a B.

Honda Stepwgn RP5 Spada Hybrid G

The Honda Stepwgn RP5 Spada Hybrid G is the volume-grade model and the sweet spot of the range for most buyers. It is aimed at families who want a better balance of comfort, resale value, and everyday usability without stepping all the way up to the top-spec version. Compared with the B, it adds the features that make daily ownership noticeably easier and more premium. On the outside, dual power sliding doors are almost always standard, which is a major convenience upgrade for family use, and LED fog lights are also typically included, giving the front end a more complete look.

Inside, the G grade feels more upmarket. It usually gets Honda’s “Prime Smooth” combination seats, which mix synthetic leather on the bolsters with fabric in the centre sections. This gives the cabin a more premium appearance while also making the seats easier to wipe clean than the B grade’s full-cloth trim. The steering wheel is upgraded to a genuine leather-wrapped unit, and the G also adds two USB charging ports in the back of the front seats, which are especially useful for second-row passengers. Heated front seats are generally standard as well, making the G a much more comfortable daily-use family trim. The easiest clue is the seat trim. If you can see the shinier leather-look material on the seat sides, it is usually a G rather than a B.

Honda Stepwgn RP5 Spada Hybrid G-EX

The Honda Stepwgn RP5 Spada Hybrid G-EX is the top mainstream grade and is designed for buyers who want the most comfort, refinement, and features. What makes the G-EX especially important is that it is not just a trim upgrade. It is the only standard grade with a meaningful mechanical chassis enhancement. That upgrade comes from Yamaha-developed performance dampers fitted within the body structure, which help reduce the wobble, vibration, and body shake typical of tall vans. In real-world driving, this makes the G-EX feel more settled and refined, especially on the highway.

It also adds stronger equipment. Active Cornering Lights improve night visibility by illuminating the direction of the turn, and while the wheels are still usually 16-inch, they often have a darker or more premium finish than the B. Inside, the G-EX gets tri-zone climate control, allowing rear passengers to set their own temperature rather than just fan speed, and it is also commonly fitted with a 100V / 1500W AC power outlet. This Japanese household-style plug can power items such as a laptop or small appliance, making it one of the most distinctive features in the range. The easiest way to identify a G-EX is to look for the AC 100V outlet cover and the rear climate control panel.

Honda Stepwgn RP5 Spada Hybrid Modulo X

The Honda Stepwgn RP5 Spada Hybrid Modulo X is the enthusiast-focused variant and is aimed at buyers who want a Stepwgn that looks more aggressive and feels flatter in corners. It is not just a standard Spada with a body kit. It is a factory-customised model developed by Honda’s Modulo division, with its own suspension tuning and styling package. On the outside, it stands out immediately thanks to its unique X-shaped front grille, aero bumper, more aggressive rear styling, and exclusive Modulo alloy wheels. The suspension is also lowered by roughly 15 mm compared with the regular Spada, which gives it a more planted stance.

Inside, the Modulo X continues the sportier theme with piano-black interior trim instead of the usual silver or wood-look finish. The seats often feature Modulo X embroidery, and many examples come with a large 10-inch premium navigation screen. On the road, the Modulo X feels firmer than the G-EX and handles with less body roll, giving it a more tied-down and sporty feel through corners. The trade-off is ride comfort, because bumps and rough surfaces are felt more clearly. For buyers who want the Stepwgn’s practicality with a sharper factory-tuned character, the Modulo X is the standout choice.

Importing a Honda Stepwgn RP5: The Approval Chain That Matters in Australia

SEVS match (variant-level reality check)
Before you buy anything, confirm the exact vehicle matches the actual SEVS entry you’re relying on model code/variant details, drivetrain, and build month. “Close enough” is how people end up with a car they can’t finish.

ROVER concessional approval (VIN-level approval)
You apply in ROVER for a single vehicle concessional approval. This is where the VIN and the evidence get assessed, not the sales listing story. If approved, that concessional RAV entry approval also serves as an import approval.

RAW and Model Report (the compliance work happens here)
If the pathway requires workshop compliance, the vehicle is modified/processed in line with the relevant requirements and evidence. The Department guidance also makes clear that the approval is conditional you then have to provide a Vehicle Inspection Certificate (VIC) once the vehicle has been modified in accordance with the evidence required.

AVV verification (the gate you don’t skip)
An authorised verifier checks the vehicle and the evidence stack. This is why “it looks fine” isn’t a compliance strategy.

RAV entry (the federal finish line)
Only after the VIC/verification step is accepted does the vehicle get entered on the RAV, and the guide notes that RAV entry happens after the VIC has been approved.
After that, you move into state/territory registration steps.

Carbarn can do the whole chain for you

If your goal is to buy the right Honda Stepwgn RP5 and keep the risk low, Carbarn can manage the process end-to-end, so nothing is assumed and nothing is left until after purchase.

It starts before you commit, by confirming the live SEVS eligibility for the exact RP5 variant model code, hybrid drivetrain, and build date rather than relying on generic “RP5” listings. From there, Carbarn can lodge the ROVER application for the specific VIN, ensuring the concessional approval aligns with the vehicle you’re actually buying.

Once approved, Carbarn keeps the compliance pathway RAW processing under the correct Model Report, managing the required evidence, carrying the vehicle through AVV verification, and completing RAV entry. Eligibility, approval, compliance work, and verification are handled as one continuous chain.
