Jean-René Burnier Coray and Benedict have a Swiss based company specializing in vehicle modifications, and especially vehicles 4×4. They exist in this form since 1996, previously from 1989, under the name “mechanical transformations of all kinds”.

SixMania welcomes this company in its pages for a small friendly vehicle to land all car 6 wheels, Therefore le 6×6.

It is the fruit of collaboration between François Michaud and JR Coray.

The basic idea is this : never again “to pose” thanks to three axles and articulated frame, reduce the ground pressure, not to sink into the mire.

6×6 is capable of crossing a rectangular walking 1 m high.
Made in 1986, he asked 7 months of hard work.

Le therefore 6×6 in action.

It is a technical jewel, find it by yourself :
Built around an engine injection Golf, it develops about 100 CVs for 850 kg and along 2m20. The clutch is hydraulically operated thereby “cross” the joint 6×6. Two mounted boxes “serial” provide it 25 speeds, from 0.65 km / h in 1st 60 km / h in 25th ! For obvious reasons (but he had to think…) the central shaft serves as a point of articulation between the two frames and allows a transmission by chain.
6 wheel independent, suspensions BMW, adjustable stiffness. 4 or 6 steerable wheels controlled by two power-assisted steering. A single brake disc on the front axle controlled by a Citroen high pressure oil system.
A wise central spring system helps relieve the central axle loads he should undergo.
