• The latest addition to Mercedes-Benz's Unimog range is the U1550/L37, equipped with a right-hand drive, five/six-man, four-door crew cab. The vehicle is available with GVWs from 7.5 tonnes to 12.5 tonnes.
The small cab model is based on the large-cab Unimog and incorporates a number of changes. Seats are mounted 80nun higher to improve forward visibility through a 25% larger front screen. The roof has been raised by 120nun providing an extra 40mm headroom. Interior width has been increased by 90nun.
Ergonomically, the interior is of the same standard as that of the large Unimog cabs which have extra sound insulation and an improved heating system, with quieter fan. The system is intended to speed up screen defrosting.
Power steering is standard on all UK models and those versions fitted with an eightspeed gearbox have an eightlamp indicator to assist gear selection.
All heavier models, with the new larger square-lined cab, are powered by Mercedes' 5.9litre 0M366 six-cylinder in-line diesel. In naturally-aspirated form it develops 76kW (102hp) while turbocharging gives a

choice of 93kW, 116kW and 1271(W (125hp, 156hp, and 170hp) power outputs.
Stroke and bore have been increased while inlet and exhaust ports have been redesigned to improve air flow to match turbocharging characteristics. A torque increase of 14% provides more flexibility.
Better combustion efficiency is said to give a cleaner burn, reducing exhaust emission levels, and improving fuel consumption by around 10%.
Unimog has established its reputation mainly within the farming community, serving as cross-country transport and performing many of the functions of a traditional tractor.
There are more than 1,000 vehicles of this type in service in the UK. In the light of recent incidents, a number of the emergency services are now looking at crew cab versions more closely.
