Carrozzeria designs : Pininfarina 1800 1967

Plenty of subsequent speculation from commentators has concluded that, with this styling, the 1800 could have gone on to be a huge international hit. However, we’re not so sure that buyers would have been ready to take the leap in the late 1960s.

I think the Chevy Monza borrowed some design clues.

1977 Chevrolet Monza Mirage: A Win Win Situation?

The Term ‘Race on Sunday Sell on Monday’ was already a tired cliché when Chevrolet rolled out it’s new H Body cars late in 1974. The most attractive of these, quite possibly the Chevrolet Monza looked like it could be the answer to Ford’s Mustang II.

EDIT-1


GM H-body

The Monza was introduced in 1975. GM's other brands also introduced their versions of the Monza: the Oldsmobile Starfire, the Buick Skyhawk, and the Pontiac Sunbird. The Monza, based on concept cars designed by Pininfarina (1971/1972 Ferrari GTC+4), was designed to use a two rotor Wankel engine, but that engine never reached production. Instead, the Monza appeared with either the Vega's 4-cylinder or a 262ci small block V8 (350ci in California). Later engines include the Pontiac Iron Duke 2.5l inline four, a 3.2l V6, the Buick 3.8l V6, and the Chevy 305 V8. The Monza 2+2 hatch won Motor Trend's "Car of the Year" for 1975. All H-body production ended for the 1980 model year.

A parallel path to domestic efforts of Bill Mitchell and Larry Shinoda (see below)?
