Setra TopClass: 400 and 500 series, engines and trims
Setra TopClass — the top-tier long-distance and tour coaches from the German manufacturer, with a history dating back to 2001. We're looking at the 400 and 500 series, the most common engines, and what to check when buying a used coach.
TopClass at a glance
TopClass is Setra's premium specification for long-haul journeys and tourist trips. These are high-deck (HD) two- and three-axle coaches with generous luggage compartments, and some versions are also available as double-deckers (DT).
In the Lithuanian market, these coaches typically arrive from Western European operators after a few years of intensive service. Buyers appreciate them for their comfort, robust construction, and the extensive Mercedes-Benz service network.
Which series to choose
The TopClass 400 series was introduced in 2001 and has become the most widespread in the used market. It's reliable, well-refined technology, but some vehicles already have high mileage, so the key factors are technical condition and service history.
The TopClass 500 series was launched in 2012: more modern styling, Euro VI engines, more safety and driver-assistance systems. It's pricier in the used market, but a better choice if you need longer service life and lower running costs.
Engines and gearboxes
The TopClass 400 series most commonly features six-cylinder Mercedes-Benz diesels (such as the OM 457 LA) with SCR systems and Euro 3–5 standards.
Transmissions are manual or automated (Telligent, later PowerShift). Automated boxes are more convenient for the driver but require timely oil and hydraulic maintenance.
What to check when buying a used TopClass
Firstly, check the mileage according to the tachograph data and the service book. Inspect the gearbox shifts, clutch condition, engine oil leaks, the SCR/AdBlue system, and exhaust gas cleaning sensors.
For the body and chassis: check the air suspension struts, axle and steering joints, door mechanisms, roof hatches, and climate control system. Interior trim and seats often need refreshing, so assess their wear and tear and the condition of the luggage compartment doors.
