The “senior” Pontiac’s had restyled bodies, but managed to retain a distinct “Pontiac” flavor. All models were shortened by four inches and narrowed by 21/2 inches, wheelbases got cut from 122 to 119 on the Catalina, and Ventura series, Star Chiefs and Bonnevilles were 123 inches down from 124.

Based on a unit-body Chassis of 112 inch wheelbase shared with other GM compacts, the Tempest broke with engineering traditions with a four-cylinder engine, curved, torsion bare driveshaft and independent rear suspension differential transmission combination know as trans-axle. Vibration , the past enemy of four cylinder engines, was kept to a minimum by the extra-sturdy block and crankcase of the of the big four cylinder, and was isolated from the body by widely rubber mountings, The new engine developed 110 horsepower with the Manual transmission, 130 with the automatic.
