1972 Javelin AMX


1972 Javelin AMX


A 1971 Javelin AMX, track-modified and driven by Mark Donohue, has won consistently in the tough Trans-Am road races.

Leaving drivers of other American sporty cars gasping. Consistently.

This year, we've added even more to our AMX from what we've learned by winning Trans-Am races.

Javelin gives you a choice of six engines and four transmissions.

And now available with 6-cylinder and V-8 engines, optional ventilated-rotor front disc brakes (manual or power.) You don't have to race to know what that says about our engines.

Rocker arms on our 6-cylinder and V-8 engines use new "cylindrical" bearings for quieter valve train operation and longer service.

Front suspension has a new "zero-lash" ball-joint that hangs tough.

So if you're going to buy a sporty car in '72, buy one that's going places.



Curved instrument panel. Standard AMX 3-spoke 15" steering wheel (optional on SST)



Standard power for AMX is the 304 CID (available on SST) Two versions of the 360 CID, plus a 401 CID are also available, including AMX "Go" packages with cold-air carburetor induction.






Console mounted gear selector for new Torque-Command automatic transmission.


Combination tachometer/clock (Tick-Tach.) Part of optional Rally-Pac instruments for V-8's. And with "Go" package. Also optional 8-track stereo tape player with manual radio and 2 rear speakers.


Optional 15" x 7" slot-style wheels with E60 x 15 Polyglas tires. Part of "Go" Package for 360 or 401 CID V-8 engines.
