In March 1968 American Motors Corporation introduced the AMX which stood for “American Motors Experimental”. This was a high performance car that was a rare two-seat car that came from a car manufacturer that was not known for producing high performance cars.
The AMX had styling that was very similar to the American Motors Javelin which had gone on sale a few months earlier in September, 1967. The main difference between the Javelin and the AMX was that the wheelbase of the Javelin was 109 inches, while the AMX had a wheelbase of only 97-inches.
Only V8 engines were available in the AMX. The standard AMX engine was a four-barrel carburetted 290 cubic inch engine that produced 225 horsepower. The intermediate option was the 343 cubic inch V8 engine that produced 280 horsepower, while the big option was the 315 horsepower 390 cubic inch V8 engine.
The AMX was produced only from 1968 to 1970. In 1970, the base engine was the 290 horsepower 360-cubic inch V8 engine with a floor-mounted 4-speed with a Hurst shifter. The optional V8 engine was a 325 horsepower 390 cubic inch engine.
The highest performing AMX was the 1969 AMX SS model which was either 52 or 53 AMX cars that were shipped to Hurst Industries to have their performance upgraded. These cars had two four-barrel carburetors on an Edelbrock cross-ram intake as well as Doug’s Headers. These modifications reportedly increased the horsepower of the 390 cubic inch engine to 340 horsepower.

The AMX had a relatively short lifespan. It was dropped by American Motors in 1971, as they turned their attention to other cars like the Javelin, Hornet and Gremlin.
As shown in the above image, the 1970 AMX had a few more styling lines and gimmicks as compared to the 1968 AMX.
I have included a road test of a 1968 American Motors AMX that was published in Canada Track & Traffic.
