This is an example of the First Magirus truck made. The first prototypes were built in 1916 and underwent exhaustive testing  until the official launch in September 1917. The 3 tonne truck was available in two versions. The 3C had a 'Cardan' Joint transmission. ( Cardan joint is the original name for a universal joint )

The other version was the 3K with a 'Ketten' or chain drive as shown here. The 3 refers to 3 tonne capacity.

This model was driven by the water-cooled petrol engine as detailed below.

The V110 Petrol engine :-

4 cylinder, 6082cc, 110mm stroke x 160mm bore, 40HP @ 1100 rpm

Designation - 'V' = vier (four), 110 = stroke.

1919 2C Bus , powered by the V110 engine.

Capacity - 18 passengers seated and 6 standing

Performance - 26 km/h

Here is an MM3 Magirus fitted with specialist lift equipment for service of overhead tramlines.
This and the larger MM4 were powered by 'Maybach' 6 cylinder engines, made by Magirus under licence.
The market was demanding larger engines but Magirus 6 cylinder units were still under development.
This commercial decision ensured the vehicles remained in the public eye, with a tried and tested engine.
These were 6995cc petrol units turning out around 100HP.The MM4 variants were used for buses. 
In 1929 the first Magirus built 6 cylinder petrol engines came off the line.
The S85 4255cc 55HP,  S88 4562cc 65-70HP and S105 7793cc 110HP, variants were used to manufacture an all-Magirus product again.

In 1930 this remarkable Police bus made an appearance as the MM4.

The size of the bonnet reflects the 100 HP 12 cylinder Maybach petrol engine beneath.

This was one of the last large petrol driven Magirus vehicles.

In 1933 the First 'M'series truck with Magirus Diesel power was built.

The 1929 'S' range of petrol engines formed the basis of the New 'D' diesel versions.

On the right is an M206 with a D88 4562cc 6 cylinder diesel engine, 65HP @ 2000rpm.

The iconic Magirus Z95D engine introduced in 1934,was the top model of a revised range of Diesel engines .

This flat 12 cylinder Boxer engine was made up from 2 x S95D 5316cc 88HP in a common crankcase.

The nett result: 10632cc, producing 150HP @ 2000rpm.

This engine was mounted under the chassis rails in the M65 Trucks and Buses.

To see better detail of the Z95D Click HERE for an enlargement. My personal view is that the M65 in the lower right corner is a futuristic looking vehicle. The German market considered it 'too' different and it never actually went into production.

NOTES : The Rundhauber's design was not compatible for Off - Road use, as the  bonnet shape would not work with the highly flexible chassis.  Rundhauber models were only ever manufactured in 2 axle configuration.

This 120-16 shows the next step down where the IVECO

badge dominates so its now, IVECO MAGIRUS.

The end of this sorry decline is epitomised by the truck on the left. 

The badge states IVECO but it is fixed to  a German cab, housing an iconic Deutz engine.

These are then mounted on the German High Tensile steel chassis with the Magirus Hub reduction axles and

legendary suspension system.

This extreme badge engineering is the last step in the political processes which has lead to the complete loss of the name MAGIRUS DEUTZ.

The IVECO organisation has now continued to evolve and the next name to go down a similar road was FORD trucks.

IVECO can do what they like, but the names of MAGIRUS and DEUTZ will go down in history as two of the finest exponents of innovative ideas and extreme quality, that Germany has ever produced.

The companies will continue to produce fine products but unfortunately as separate entities.
