Hyundai advertises that the i20N is fitted with a Dual coupled torsion beam axle (CTBA).
However, it isn’t fitted and Hyundai are ignoring me when I ask why?
Anyone know?
 
It's listed in the spec sheet as 'Coupled Torsion Beam Axle'.


See the second to last pic in the above link.

Looks very similar to the below pic of the i20n in the 3rd pic of the link below.
 
There’s a Hyundai patent for the ‘Dual coupled torsion beam axle’ here:

The ‘Dual’ system has tie rods connected to the rear wheel carriers and anchored at the centre of the axle. This allows toe in and out dependant on suspension movement.

A ‘Top Gear’ road test mentions that the axle is ‘coupled’ to give semi indépendance and Hyundai advertises the i20N ‘Dual’ axle but both are clearly is untrue!

I dont know where you are, but in Australia it is only specified as 'coupled' not the 'dual coupled' you mention.

Ymmv :)
