The Mercedes-Benz O371 is a series of bus and coach models manufactured by Mercedes-Benz do Brasil S.A. primarily for the South American market, although some units were exported. Produced from the mid-1980s until the mid-1990s, the O371 series was a highly successful and iconic range of vehicles, renowned for its robustness, reliability, and versatility across various transport applications, from urban public transport to long-distance luxury coaching.
Overview and Development
The O371 series succeeded the popular O362 and O364 models and represented a significant evolution in design, engineering, and passenger comfort for Mercedes-Benz's Brazilian bus division. It introduced more modern styling, improved ergonomics for drivers, and a wider range of configurations to meet diverse operational needs. The O371 was known for its distinctive rectangular headlights and a generally more streamlined appearance compared to its predecessors.
Models and Variants
The O371 family comprised several distinct models, each designed for specific purposes:
- O371 R (Rodoviário): A basic intercity coach model, typically with a shorter wheelbase and often featuring a simpler interior. It was popular for short to medium-distance routes.
- O371 RS (Rodoviário Simples): A medium-distance coach, offering improved comfort and amenities over the 'R' model. It often featured air conditioning and more comfortable seating.
- O371 RSD (Rodoviário Super Deluxe): The flagship long-distance coach model, characterized by its elevated floor (high-deck design), larger luggage compartments, and often a three-axle configuration for increased capacity and stability. These models were equipped with premium interiors, air suspension, and powerful engines, making them suitable for long-haul luxury travel.
- O371 U (Urbano): An urban bus model designed for city public transport. It featured multiple doors and standing room for passengers.
- O371 UP (Urbano Padron): A larger urban or suburban bus, often articulated (bendy bus) or with a longer rigid chassis, designed for high-capacity routes.
- O371 UL (Urbano Leito): A variant name that might be confused with "leito" (sleeper) but was generally used for urban/intercity applications as well, sometimes indicating a longer version.
Mercedes-Benz do Brasil also supplied chassis versions of the O371 (e.g., OH 1625 L for coaches, OF series for front-engined urban buses based on truck chassis) to independent coachbuilders, allowing for a wide variety of body designs to be built upon the O371 platform.
Technical Specifications (General)
While specifications varied significantly between models and production years, common features included:
- Engine: Diesel engines, typically from Mercedes-Benz's OM-series, offering various power outputs. Common choices included the OM 366 LA (turbocharged and intercooled) and the more powerful OM 447 LA (for coach models), known for their durability.
- Transmission: Manual transmissions were standard, often with 5 or 6 speeds. Automatic transmissions were less common but available in some urban models.
- Suspension: Depending on the model, leaf spring suspension was standard for urban and simpler intercity models, while air suspension was a key feature of the more comfortable and luxurious coach variants (e.g., O371 RSD).
- Braking System: Air brakes were standard across the series.
Market and Legacy
The Mercedes-Benz O371 series dominated the bus and coach market in Brazil and other Latin American countries throughout its production run. Its reputation for durability, ease of maintenance, and the widespread availability of parts made it a preferred choice for transport operators. Many units continued in service for well over two decades after their manufacture.
The O371 was eventually succeeded by the Mercedes-Benz O400 series in the mid-1990s, which further evolved the design and technology of Mercedes-Benz's bus offerings in the region. Despite being phased out, the O371 remains a significant model in the history of Brazilian and South American public and intercity transport.
