1957 Triumph TR3 Roadster
Introduced in October 1955 as an evolution of the successful TR2, this British roadster became the first production car from Britain to feature standard front disc brakes. The 2.0-liter four-cylinder engine produced 100 horsepower, enabling a top speed of 102 mph despite the car’s simple construction and affordable pricing.
The most obvious visual change from its predecessor was the adoption of a flush-set egg-crate grille design. Initial models produced 95 horsepower, but power increased to 100 horsepower by mid-1956 through cylinder head improvements. In 1956, Girling front disc brakes and a stronger rear axle were standardized.
Triumph produced 16,847 examples from 1955 to 1957, with approximately 90 percent exported to American shores. The roadster’s combination of performance and value made it highly competitive against rivals like the MGA and Austin-Healey 100.
