TheMitsubishi Fuso Rosa (Japanese:三菱ふそう・ローザ, or simplyMitsubishi Rosa) is aJapaneseminibus based on theMitsubishi Fuso Canter manufactured byMitsubishi Fuso Truck and Bus Corporation. The Mitsubishi Fuso Rosa was launched in 1960 and is now in its fifth generation, known as the BE7. In Japan, Asia-Pacific, Mid-East, Africa, Jamaica and South America, its principal competitors are theIsuzu Journey,Nissan Civilian,Mazda Parkway andToyota Coaster.
The Mitsubishi Rosa was launched in 1960 by theMitsubishi Heavy Industries (formerly China-Japan Heavy Industries) and was called Mitsubishi Rosa. In 1964, three companies merged with the Mitsubishi Heavy Industries to become a new Mitsubishi Heavy Industries, and the Mitsubishi Rosa became a Mitsubishi Fuso product to replace the Fuso MB720 minibus in 1966.
Mitsubishi officially launched the Rosa minibus in 1960. At that time, the factory was coded as B10 and developed from the chassis of the original Mitsubishi Jupiter T10 truck.[1] Its body style is similar to theMercedes-Benz O 319 minibus, with a length of approximately 5.4 meters.
In the following year (1961), Mitsubishi evolved to B20 on the basis of B10, which is an extended version of B10, which ranges from 6.25 to 7 meters in length.
In 1973 Mitsubishi released the second generation, which is similar as the first generation, the main difference is the design of the front has been largely revised, and a large number of components can be shared with the Mitsubishi trucks. In the beginning, there was BC2 (short-range gasoline version), BE2 (short-range diesel version) and BH2 (long-range diesel version). In 1981, the BK2 series was introduced (long-range version with a width of 2.3 meters).

The third generation Rosa (chassis codeBE4 series) was introduced in June 1986 (1986-06) as a full model change over the BE3 "Pretty Rosa". The BE4 adopted a more modern cab-forward profile with a panoramic windshield, a lower beltline, and factory-standardrectangular twin headlamps on upper trims; following a minor change in January 1990 (1990-01), the rectangular two-lamp arrangement was standardized across all models.[3][circular reference] Offered in short (6,200 mm (20 ft 4 in)) and long (6,950 mm (22 ft 10 in)) bodies, seating ranged from 26 to 29 depending on interior specification.[4]
Rectangular headlamps, a one-piece windshield and a lower beltline improved forward visibility and modernized styling. Trims included:
All BE4 models used Mitsubishi's4D3-series inline-four diesels withgear-driven timing (no timing belt). Rated outputs (period figures) are shown in PS and SAE hp, with torque in lb·ft:
| Engine | Displacement | Induction | Compression | Power | Torque | Notes |
|---|---|---|---|---|---|---|
| 4D31 | 3,298 cc | Naturally aspirated DI | ~18:1 | 100 PS (98 hp) @ 3,200 rpm | 182 lb⋅ft (247 N⋅m) @ ~2,000 rpm | Base/School |
| 4D31T | 3,298 cc | Turbocharged DI | 17.5:1 | 118 PS (116 hp) @ 3,200 rpm | 206 lb⋅ft (279 N⋅m) @ 2,000 rpm | Standard, Deluxe, Royal |
| 4D32 | 3,567 cc | Naturally aspirated | ~18:1 | 110 PS (108 hp) @ 3,200 rpm | 194 lb⋅ft (263 N⋅m) @ ~2,000 rpm | Shuttle |
| 4D33 | 4,214 cc | Naturally aspirated DI | ~18:1 | 120 PS (118 hp) @ 3,200 rpm | 210 lb⋅ft (280 N⋅m) @ ~2,000 rpm | Heavy-duty |
| 4D34T (post-1990) | 3,907 cc | Turbocharged | ~17.5:1 | 155 PS (153 hp) @ 3,200 rpm | 280 lb⋅ft (380 N⋅m) @ ~2,000 rpm | Post-MC Royal/Deluxe |
A 5-speed manual was standard throughout the BE4 era; an automatic was added after the 1990 MC.[15] Typical long-body axle ratios were around4.875:1—a figure also shown in later Rosa specification tables—and 16-inch commercial tyres (205/85R16).[16]
| Gear | Ratio* | Road speed @ 3,200 rpm |
|---|---|---|
| 1st | ~5.00 | ~7 mph (11 km/h) |
| 2nd | ~2.80 | ~15 mph (24 km/h) |
| 3rd | ~1.60 | ~25 mph (40 km/h) |
| 4th | 1.00 | ~40 mph (64 km/h) |
| 5th | ~0.77 | ~55 to 60 mph (89 to 97 km/h) |
Pre-MC BE4 models used leaf springs front and rear. After the 1990 MC, upper trims adopted independent front suspension; 4WD appeared on long-body models; in 1992, some tourist models gained rear air suspension.[18][19] Hydraulic service brakes with an exhaust brake were standard; front discs with rear drums were widely used in this era.
Operator reports vary with load and route. Period figures for long-body 4D31T buses in mixed shuttle duty typically fall around 6 to 7 km/L (14 to 16 mpg‑US) (≈14 to 16.5 miles per US gallon (16.8 to 14.3 L/100 km; 16.8 to 19.8 mpg‑imp)), with fully loaded tourist service and continuous A/C dropping closer to 5.5 km/L (13 mpg‑US) (≈13 miles per US gallon (18 L/100 km; 16 mpg‑imp)). (Published factory consumption for 1980s BE4 models is scarce online; values reflect operator/market data and period brochures for comparable Rosa/Canter drivetrains.)[22]
Age-related items reported by fleets and operators include overheating damage from neglected cooling systems (especially on turbo engines), oil leaks at rocker cover and crank seals, vacuum pump O-ring seepage, rear main seal contamination of the clutch, glow-system faults, wear in suspension and steering (bushings, kingpins, steering box), corrosion at stepwells/lower panels/roof seams, and shrinking window rubbers allowing water ingress. Original R12 A/C systems typically require conversion to R134a with new hoses and seals.[23]

The fourth generation (BE6 series) is an improved version of the third generation. The design of the body of the car was greatly modified, and the distance between the front axle and the door was considerably reduced. In addition, the taillights are round, different from the second and third generation. There are both Automatic and Manual models available.[26] In 1998, a super long body was added to the line-up, bringing the maximum capacity of all the vehicle to 34 people. In 2002, natural gas engine were offered to the Mitsubishi Rosa.Transmac inMacau was supplied with a dual-door version.
