11. 1958 Pontiac Bonneville Tri-Power
The new styling of the Pontiac brand meant a new approach to the performance market. It also sparked the birth of one of the most powerful American muscle car brands. Despite a few impressive models, Pontiac’s muscle quest began in 1958 when they presented the Bonneville with their Tri-Power option.
This was a top of the line model featuring a big 370 V8 engine with three two-barrel Rochester carburetors, producing up to 310 HP. In late 1958, Pontiac introduced an even hotter setup with up to 330 HP they designed for racers and NASCAR.
