The 1958 Bonneville made a bold statement with its fresh design, featuring a completely revamped body on a Cadillac-based cruciform frame. Pontiac showrooms welcomed not only the convertible but also a new hardtop version. Enhancements included coil springs at the rear for a smoother ride, while a shorter platform contributed to improved handling. Taking full advantage of these updates, the Bonneville boasted a new 370 cubic inch 4-barrel engine, delivering 285 horsepower with 10:1 compression and paired with the 4-speed Hydra-Matic transmission.
