The 1971 Impala Turbo Hydra-Matic Sedan represented the stronger end of the final-year fourth-generation lineup, equipped with a three-speed Turbo Hydra-Matic automatic and an engine rated at 365 hp with 630 Nm of torque. The 0 to 100 km/h time of 8.8 seconds was competitive for a full-size sedan of the era, and the Turbo Hydra-Matic transmission offered noticeably smoother and more responsive shifts compared to the two-speed Powerglide available in the same model year.
