# Mercedes-Benz O405

The Mercedes-Benz O405 is a single-decker bus manufactured by Mercedes-Benz from the mid-1980s to the early 2000s as either an integral bus or a bus chassis; it was the last VöV SL-II standard bus in production. It replaced the O305 and was widely used in Europe, the United Kingdom, Australia and Singapore with 12,000 produced.

## Standard floor version

The step-entrance version was known as the O405. A 3-axle articulated version was also built known as O405G and a trolleybus as the O405T. There were two generations of O405, designated as O405 MkI and O405 MkII. Most of them have their boxy roof dome (slightly arched) with a double-curvature windscreen, separately mounted destination indicator and pantograph system windshield wipers that was used on some buses such as the Dennis Dart, Leyland Lynx, MAN NL262 and the MAN SL202.

### O405 Mark I

The O405 Mark I was marketed between mid-1980s and early 1990s. It was unveiled in September 1983. It featured a Mercedes-Benz OM447h naturally aspirated Diesel engine with outputs of either 157 kW (211 hp) or 184 kW (247 hp). Optionally available was a naturally aspirated compressed natural gas (CNG) engine model M447hG with 150 kW (201 hp) output. The gearbox coupled to the engine was usually the Mercedes-Benz W3E110/2.2R or Mercedes-Benz W4E112/2.2R (the former being able to handle the more powerful 184 kW engine), although there have been other gearboxes such as the ZF 5HP 500 or Allison B300R coupled to the engine.

### O405 Mark II

The O405 Mark II was marketed from the early 1990s to the late 1990s and into the early 2000s in some parts of the world. It featured a Mercedes-Benz OM447hA turbocharged engine with an output of 184 kW (247 hp), although some examples feature either a naturally aspirated engine (OM447h-II), a turbocharged engine (OM447hA) or a turbocharged, intercooled engine (OM447hLA). The gearbox coupled to the engine was either the ZF 4HP 500 or 5HP 500, or the Voith D864.3.
From 1994, this chassis was available with the M447hG Euro II 175 kW (235 hp) naturally aspirated compressed natural gas (CNG) engine.

## Low-floor version: O405N

The low-floor version of the regular O405 was known as the O405N (or O405GN for the 3-axle articulated version) was released in September 1989, later a further developed version was also built, it was known as the O405N²/O405N2 (or O405GN²/O405GN2 for the 3-axle articulated version). The O405(G)N do not have steps at the entrances and exits, but the seats are mounted on "platforms". The GN2 type addressed this problem. These buses are usually fitted with ZF transmissions, but some are fitted with Voith examples. It has a boxy roof dome (slightly arched) similar to the MAN NL202 and the MAN NL262 with a double-curvature windscreen with a separately mounted destination display just that it has a full low floor layout with seats mounted on platforms.

## Low-entry version: O405NH

The low-entry version of the O405 was called the O405NH chassis which was produced by EvoBus for the Australian market. Much of its popularity with government and private operators alike can be attributed to the popularity of the Mercedes-Benz O405 MkII chassis that it replaced.
The chassis was derived from a combination of the rear modules of an O405 MkII chassis and the front modules of an O405N²/O405GN² chassis. Because of the difference in height between the front and rear modules of the chassis, there are one or more steps leading up from behind the centre door position to a standard O405 floorline. Because the chassis has a horizontally-mounted engine, there's no room for a rear door. This low-entry concept has become very popular in Europe – many integral products using this concept have been released such as the Mercedes-Benz Citaro LE.

## Suburban version: O407

The suburban version was called O407 (or O407G/O405GÜ for the 3-axle articulated version), It had a single door at the front and a pair in the middle, with all of the seats facing towards the front of the bus. It featured a Mercedes-Benz OM447h naturally aspirated engine with output 177 kW (237 hp) and 6-speed manual Mercedes-Benz gearbox.
