Double wishbones suspension

To many suspension designers, double wishbones are the ideal suspension. It can be used on front and rear wheels, it is independent and most importantly, it has near perfect camber control. For over 40 years and even today, this is the first choice for racing cars, sports cars and High end Saloons

 

Basically, double wishbone suspension always maintains the wheel perpendicular to the road surface, irrespective of the wheel's movement. This helps to ensure good handling.

Traditional double wishbones consists of 2 parellel wishbone arms of equal length, which has the drawback of excessive tire scrubbing because of the large variation in track width as the wheel moves off the neutral position. 

Therefore engineers developed unequal-length non-parallel A-arms to solve this. By tilting the upper A-arm, anti-dive function can also be achieved.
 

Double wishbone suspension has been very popular in American cars. 

But not so much in Europe because cars are smaller and thus cannot accommodate this relatively space-consuming type  of suspension. 

It is also more costly than MacPherson struts and torsion beams because it involves more components and more suspension pick up points in the car body. 

For to these reasons, very few smaller cars adopt it. Honda are one of the few makers who try to make heavy use of it. (See pictures below)

 

So do American cars handle better then european ones. I think not, but this is more down to the size, weight, suspension settings, than any neglect in the design department.
