Mercury Cougar XR7

The 1970 Cougar appearance was similar to the 1969 model, however there were numerous changes inside and out. It now sported a new front end which featured a pronounced center hood extension and electric shaver grille similar to the 1967 and 1968 Cougars. Federally mandated locking steering columns appeared inside, and the aforementioned new nose and taillight bezels updated the look on the outside. The 300 hp (224 kW) 351 "Cleveland" V8 was now available for the first time, though both the Cleveland and Windsor engines were available, if the buyer selected the base model 2-barrel motor.
