Four-wheel
steering on cars is nothing new but now comes the news that Dana Corporation is
to supply rear axle assemblies to Delphi for a ‘groundbreaking’ four-wheel steering
system.
It’s due to appear on a line of General Motors pickup trucks for the 2002 model
year and, Delphi says, will be the first time a full-size pickup truck line
has featured four-wheel steering.

The trucks will use Delphi’s newly-developed Quadrasteer, an electronic four-wheel
steering system said to ‘significantly improve handling and manoeuverability
in full-size vehicles’.
The four-wheel steering electronically controls the direction of the rear wheels,
helping shorten the turning radius. This, Dana claims, allows big pickups to
manoeuvre as easily as compact cars.
