Strange that there is nothing in the press launch pack, given to jounalists, but from the first brochure
" Rear Wheel Steer
As a result of the "No Compromise" instruction, the Alfa GTV boasts one of the most sophisticated and radical suspension systems of any car in the world. plus roadholding and handling that are, indeed, "Magnifico"
The front suspension utilises a fairly conventional MacPherson struts, offset coil springs, lower wishbones and an anti roll bar. But it is at the rear that Alfa Romeos engineers have established the unit that accounts for the car's limpet-like grip.
The independant, multiple arm rear suspension comprises quadrilateral geometry with an upper triangle, double lower arms, coil springs and anti roll bar secured to a light alloy subframe which is, in turn, mounted onto the cars body.
The design of this geometry, and the fine tuning of the bushes, is such that during the initail stages of turn, the centrifugal forces create a small "rear wheel steer" effect in the opposite direction to the way the front wheels are being pointed. Then, as the centrifugal forces build up through the corner, the rear wheels start steering in the same direction as the front wheels.
The result is a more positive "attack" into the first stages of cornering and increased stability in the later stages. The grip that is then produced is quite phenomenal."
