Pontiac Bonneville (1960)

The new long and lower Bonnevilles had been introduced in 1959 and were acclaimed for their slender, sporty looks and good road-holding. They carried on in similar mechanical guise for 1960, but this was the only year that, styling-wise, the Pontiacs didn't have the split grille. Underneath, the car used a X-braced chassis with unequal-length wishbone front suspension and a live rear axle. Changes were made to the rear suspension with the attachments points of the upper-control arms raised and given stiffer bushings to better locate the axle. Other changes to the drive train included a redesign of the bellhousing to lower the transmission tunnel and give an inch extra room inside the car. The standard engine was again the 389ci (6.3-liter) as in 1959, but the top option was the 10.5:1 compression unit which ran with a high-lift camshaft, less restrictive heads and a Tri-Power intake.
