When it comes to Japan’s kei trucks and vans, the Honda Acty has long been one of the most versatile and dependable vehicles in its category. First introduced in 1977, the Acty line became synonymous with reliability and practicality, often serving as the backbone for small businesses, farmers, and delivery services across Japan. While earlier models like the HA3 and HA4 built a reputation for rugged efficiency, the HA8 and HA9 models, produced between 2009 and 2022, represented a more modern, refined evolution of Honda’s kei truck design. These models not only complied with stricter emissions standards but also delivered meaningful changes in performance, safety, and overall drivability.
Understanding what makes the HA8 and HA9 special requires looking under the hood and beyond. Their engineering changes reflect Honda’s effort to keep the Acty relevant in a rapidly changing automotive landscape. For enthusiasts, collectors, and business owners still using these vehicles today, these differences are worth knowing, especially when considering long-term maintenance or sourcing Honda Acty Replacement Parts.
The Context: Why the HA8 and HA9 Emerged
By the late 2000s, kei trucks were facing new challenges. Japanese regulators imposed stricter emissions and safety standards, while customer expectations began to shift toward comfort and efficiency without sacrificing durability. Honda introduced the HA8 (Acty Truck) in 2009 and the HA9 (Acty Van) in 2010 as responses to these demands.
These generations were not simply facelifts; they incorporated deeper mechanical improvements, particularly in the powertrain and structural design. While the basic Acty formula of a compact, mid-engined kei truck remained intact, the HA8 and HA9 took significant steps forward.
Powertrain: Midship Reliability with an Updated Engine
The hallmark of the Acty has always been its midship engine layout. This unique design, with the engine mounted behind the seats but ahead of the rear axle, offers better weight distribution and stability compared to front-engine kei trucks.
For the HA8 and HA9, Honda introduced the E07Z engine, a 656cc three-cylinder SOHC unit that replaced the earlier E07A used in the HA6 and HA7. Though the displacement remained the same to comply with kei car regulations, the E07Z received updates in fuel injection, combustion efficiency, and emissions control. The engine produced around 45 horsepower, which may sound modest, but within the kei category it was competitive.
The big change was the introduction of PGM-FI (Programmed Fuel Injection) across all models, replacing carbureted setups seen in older versions. This improved throttle response, fuel economy, and reduced emissions. The result was a kei truck that met stricter Japanese 2005 Emission Standards without losing the characteristic Acty balance between durability and usability.
Transmission and Drivetrain Improvements
Honda retained both rear-wheel drive (RWD) and four-wheel drive (4WD) options for the HA8 and HA9, giving users flexibility depending on their work environment. Farmers, construction workers, and rural drivers often opted for the 4WD versions, which came with a low-gear range for challenging terrain.
Transmission options included a 5-speed manual and a 3-speed automatic, though most Actys sold in Japan were manual due to the preference for durability and lower cost. The manual transmission in the HA8/HA9 was refined for smoother shifts, while gear ratios were adjusted to make better use of the small engine’s output, especially in urban stop-and-go traffic.
Chassis and Suspension Refinements
One of the most significant mechanical evolutions came in the chassis and suspension design. The HA8 and HA9 adopted a more rigid frame compared to their predecessors, improving both safety and handling. Honda also fine-tuned the independent strut front suspension and De Dion rear suspension setup.
This design helped maintain stability even with heavy loads, a crucial requirement for kei trucks and vans that often carry tools, goods, or agricultural supplies. Combined with the mid-engine layout, the handling of these models was praised for being more car-like, particularly in the HA9 van version.
Safety Enhancements
Kei trucks of the 1990s and early 2000s were often criticized for offering minimal safety features. By the time the HA8 and HA9 were launched, Honda addressed this with several upgrades:
Driver and passenger airbags became standard.
Anti-lock Braking System (ABS) was introduced, providing better control during emergency stops.
A stronger cabin structure improved crash safety, thanks to Honda’s G-CON (G-Force Control) body design philosophy.
These changes didn’t make the Acty a luxury vehicle, but they provided reassurance to owners who used them daily in urban or rural environments.
Emissions and Environmental Adaptations
Japan’s kei regulations limited engine size and output, but manufacturers were pushed to innovate in emissions reduction. The E07Z engine in the HA8 and HA9 incorporated updated catalytic converters, advanced fuel injection mapping, and precise combustion control.
These improvements ensured compliance with Japan’s evolving emissions standards. At the same time, fuel economy benefited, with Actys of this generation averaging around 15–18 km/l depending on driving conditions.
Interior and Comfort: Modest but Practical
Under the hood wasn’t the only place Honda introduced changes. While still spartan compared to passenger cars, the interiors of the HA8 and HA9 gained small but meaningful upgrades. Better sound insulation, more ergonomic seating, and revised dashboards improved comfort during long workdays.
The HA9 van version offered even more utility, with flexible cargo space that appealed to delivery services and tradespeople. Unlike earlier generations that felt barebones, the HA9 aimed to balance practicality with a touch of modern convenience.
The End of the Acty Era
Production of the Acty HA8 and HA9 continued until 2021 for the truck and 2022 for the van, when Honda discontinued its kei truck line altogether. The decision reflected the increasing difficulty of balancing kei regulations, modern safety requirements, and rising production costs. Honda redirected focus toward other small commercial vehicles and electric mobility solutions.
For enthusiasts and owners, the discontinuation marked the end of a unique era. The HA8 and HA9 stand as the last of Honda’s mid-engine kei trucks, carrying forward decades of innovation and reliability.
Maintenance and Parts Availability
With the Acty no longer in production, owners today often focus on maintenance and sourcing quality parts. Fortunately, the durability of the HA8 and HA9 means many examples remain on the road. Access to Honda Acty Replacement Parts is essential for keeping these vehicles operational, whether it’s for engine components, suspension parts, or transmission repairs. Many parts remain available through specialized suppliers, and the relatively simple design of the Acty makes it easier to service compared to more complex modern vehicles.
Legacy of the HA8 and HA9
What truly distinguishes the HA8 and HA9 in the Acty lineage is their blend of tradition and progress. They retained the iconic mid-engine, rear-drive formula that gave the Acty its reputation for balance and utility, while introducing refinements in emissions, safety, and usability.
For collectors, these models represent the last chapter of Honda’s kei truck story. For businesses and individuals still relying on them, they remain reliable workhorses capable of serving daily needs with efficiency.
Conclusion
The Honda Acty HA8 and HA9 models produced between 2009 and 2022 symbolize the careful evolution of a kei truck icon. Under the hood, they received meaningful updates in engine technology, emissions control, safety features, and drivetrain refinement, all while maintaining the rugged practicality that defined the Acty since its inception. Though production has ended, the HA8 and HA9 live on through their continued use and the dedication of owners who maintain them. For those who appreciate the heritage of Japanese kei trucks, these models stand as a testament to Honda’s engineering vision and the enduring value of compact, efficient utility vehicles.
