Subaru Sambar

Overview & History

The Subaru Sambar stands apart from every other kei truck on the market for one reason: it is the only kei truck ever built with a four-cylinder engine. While its competitors all use three-cylinder powerplants, Subaru equipped the Sambar with the EN07 series inline-four, giving it a smoothness and character that no other mini truck can match. Combined with a rear-engine, rear-wheel-drive layout and fully independent suspension on supercharged models, the Sambar is often called the "Porsche of kei trucks" by enthusiasts, and the comparison is not entirely tongue-in-cheek.

Subaru introduced the first Sambar in 1961, and the nameplate ran through six generations of Subaru's own design before the company ended in-house kei vehicle production in 2012. From 2012 onward, the Sambar name continues but on a rebadged Daihatsu Hijet platform, losing the four-cylinder engine and rear-engine layout that made the original special. The Sambar was designed to comply with Japan's kei vehicle regulations, which cap engine displacement at 660cc and restrict overall vehicle dimensions.

For US importers, the fifth generation (KS3/KS4, 1990-1998) and sixth generation (TT1/TT2, 1999-2012) are the relevant models. The fifth-generation trucks are currently the most commonly imported, as they have passed the 25-year federal import threshold. Sixth-generation trucks are just beginning to become eligible and represent an exciting opportunity for buyers willing to wait or source from states with less restrictive title laws.

Specifications

The Subaru Sambar's defining feature is its EN07 engine, a 658cc inline-four-cylinder unit. In naturally aspirated form, the EN07 produces 40-46 horsepower. The supercharged variant (EN07Y with a Roots-type supercharger) produces 55-58 horsepower, making it one of the most powerful naturally-breathing kei truck options available (the supercharged Sambar sits just below the 64 hp kei limit).

The rear-engine layout places the EN07 behind the rear axle, beneath the bed. This gives the Sambar a unique rear weight bias that provides excellent traction on loose surfaces, particularly when the bed is unloaded. Combined with the available four-wheel drive, the Sambar is arguably the most capable kei truck off-road.

• Engine: 658cc EN07 inline-4-cylinder (SOHC)
• Power: 40-46 hp (NA), 55-58 hp (supercharged)
• Torque: 40-54 lb-ft
• Transmission: 5-speed manual or 3-speed automatic (ECVT on some later models)
• Drivetrain: RWD or part-time 4WD with selectable low range
• Payload capacity: 770 lbs (350 kg)
• Bed dimensions: Approximately 77" L x 53" W
• Curb weight: ~1,600-1,850 lbs
• Fuel economy: 30-40 mpg
• Wheelbase: 73.4"

The supercharged Sambar models also featured fully independent rear suspension (four-link independent versus the standard leaf springs), providing a markedly better ride quality that further distinguishes the Sambar from its competitors.

Pros & Cons

Pros

• Four-cylinder smoothness: The EN07 revs smoother, produces less vibration, and sounds better than any three-cylinder kei truck engine. The difference is immediately noticeable.
• Supercharged option: The factory supercharged models offer meaningfully more power than the naturally aspirated competition without the turbo lag associated with turbocharged alternatives.
• Rear-engine traction: Excellent weight over the driven wheels, especially beneficial when driving unloaded on loose or slippery surfaces. This makes the Sambar a compelling option for farm work on hilly or muddy terrain.
• Independent rear suspension (supercharged models): A genuine ride quality advantage over the leaf-spring setups on competitors like the Suzuki Carry and Honda Acty.
• Enthusiast appeal: The Sambar has a passionate fan base. Ownership is a community experience, with dedicated forums, meetups, and an active kei truck community on Reddit.

Cons

• Fuel economy: The four-cylinder engine is slightly less fuel-efficient than the three-cylinder competition, particularly the supercharged models.
• Engine access: Like the Honda Acty's mid-engine layout, the Sambar's rear-engine placement makes routine maintenance less convenient. Accessing the engine requires working from under the truck or removing bed panels.
• Complexity: Four cylinders means more spark plugs, more valves, and a slightly more complex engine than three-cylinder alternatives. The supercharger adds another maintenance item.
• Price premium: Sambar trucks, especially supercharged 4WD models, command significant premiums. They are among the most expensive kei trucks to buy — see our kei truck vs. pickup comparison for context on value.
• Parts sourcing: Subaru ceased in-house kei production in 2012. While parts remain available through Subaru Japan and aftermarket suppliers, the pipeline is not as robust as Suzuki's.
• Weight: The four-cylinder engine and additional equipment make the Sambar the heaviest kei truck, which partially offsets its power advantage.

Common Modifications

For a broader overview, see our guide to the best kei truck mods for off-road use.

• Lift kits: 2-3 inch lift kits are available, though the rear-engine layout requires careful attention to CV joint angles on 4WD models. Suppliers like Catuned offer Sambar-specific kits. [AFFILIATE: Subaru Sambar 2" lift kit, $400-$600, https://oiwagarage.co]
• Exhaust upgrades: The four-cylinder EN07 responds well to header and exhaust upgrades. The sound of a tuned Sambar at full song is genuinely enjoyable.
• Supercharger pulley swap: On supercharged models, a smaller supercharger pulley increases boost pressure and power output. This is a popular and relatively simple modification. [AFFILIATE: Supercharger pulley upgrade kit, $150-$250, https://oiwagarage.co]
• Tire and wheel upgrades: 13-14 inch all-terrain tires are popular. The Sambar's rear weight bias means aggressive tread patterns work particularly well on the rear axle — check our kei truck tire guide for the Sambar's exact stock sizes and upgrade recommendations. [AFFILIATE: All-terrain tires 145/80R12 (set of 4), $180-$280, https://oiwagarage.co]
• Intercooler addition: Adding an air-to-air intercooler to the supercharged models reduces intake air temperatures and improves power consistency in hot weather.
• Subframe and skid plates: For off-road use, aftermarket skid plates protect the exposed rear-mounted engine from rock strikes and trail debris. [AFFILIATE: Subframe/skid plate set, $200-$350, https://oiwagarage.co]

Known Issues & Maintenance Tips

Before purchasing any Sambar, review our pre-purchase inspection checklist for a full rundown of what to look for. For help tracking down replacement components, see our kei truck parts sourcing guide.

• EN07 head gasket: This is the Sambar's Achilles heel. The EN07 engine is known for head gasket failures, a trait shared with Subaru's larger boxer engines. Watch for white exhaust smoke, coolant loss, and overheating. Replacement is labor-intensive due to the engine location. OEM gasket sets from Amayama are a reliable source for genuine Subaru parts.
• Supercharger belt and bearings: The supercharger belt should be inspected every 20,000 km and replaced every 50,000 km. Supercharger bearing noise (whine at idle) indicates impending failure. Kei truck parts suppliers like Oiwa Garage stock replacement belts and rebuild kits.
• Rust: The Sambar is no more or less rust-prone than its competitors, but the rear-engine layout means the engine compartment collects road spray and salt. Inspect the rear subframe, engine bay, and bed floor carefully.
• ECVT transmission (avoid): Some later-model Sambars were equipped with an ECVT (electronically controlled CVT). These units are fragile and expensive to repair. Strongly prefer the 5-speed manual or 3-speed conventional automatic.
• Valve adjustment: The EN07 uses mechanical lifters. Valve lash check and adjustment is due every 40,000 km.
• Oil changes: The EN07 holds approximately 2.8 liters of oil. Use 5W-30 and change every 5,000 km. Supercharged models benefit from more frequent changes (every 3,000-4,000 km). [AFFILIATE: 5W-30 synthetic oil (5 quart), $25-$35, https://www.amazon.com]
• Cooling system: The rear-engine layout means long coolant hose runs to the front-mounted radiator. Inspect all hoses and clamps carefully, and replace any that show age cracking.
• Timing belt: The EN07 is an interference engine, meaning a broken timing belt will cause valve damage. Replace the timing belt every 100,000 km without exception. [AFFILIATE: Subaru EN07 timing belt kit, $100-$150, https://www.amayama.com]
