VV'ers Please check my facts in this response to the article "GM's
junk heap" by Peter Valdes-Dapena, CNNMoney.com senior writer
In early versions, though, the Corvair's rear suspension design
seemed unsuited to the job. The car had dangerously dicey handling in
turns.
Peter,
As a reporter, you really need to do your homework. The Corvair is
actually, except for the Corvette which actually shared the same rear
suspension geometry as the '65-69 Corvair from '63 to '84, was the
best handling car of the 60's. The factors that created this fine
handling were the location of the major weight of the car over the
drive wheels, the unibody construction for rigidity, and due to the
engine location, it had four wheel independent suspension. What
caused some people to experience steering problems was not reading
their owners manuals and attending to the correct tire pressures.
Most people just assumed that all of the tires would receive the same
tire pressures. This is almost never the case on any vehicle and was
certainly true of the Corvair which had a ten pound difference
between the front and rear recommended. Also, drivers of the era,
and of course today are accustomed to experiencing understeer (front
wheels losing traction before the rear wheels in a hard turn) whereas
the Corvair, because of the weight distribution, experienced
oversteer. All cars, when pushed to their physical limits to go
where you point them will experience this phenomena. Although the
early Corvairs (60-63) did experience a pronounced negative camber in
a hard turn (usually outside of anything other than autocrossing) the
cars did not flip over as is the urban legend. In fact, Corvairs
were far less likely to flip than other cars of the era, and
certainly the modern SUV. With the introduction of the articulated
link suspension in the '65-69, the car became one that outperformed
the era's best cars in handling. Just as an addendum, the Corvair
was also the fastest stopping car of the 60's and 70's.
