1970 would be the last year for the stand alone model AMX. The AMX would become a performance option on the 1971-1974 Javelins, the 1977 Hornet, the 1978 Concord, and the 1979-1980 Spirit. There were numerous changes on the 1970 AMX, including a new hood, bumper, and grille with vents to cool the front brakes. The hood included a functioning Ram Air setup, and the rocker panel moldings simulated exhaust side pipes.
New Standard Engine
The new standard engine was bumped up from a 290 V8 to the 360 V8. The only upgrade available was the powerful 390 V8. Both engines had clearer breathing exhaust ports and four barrel carburetors. The "Go" package could be installed on either engine, and included front disc brakes, a handling package, Goodyear F70x14 small raised white letter tires, and Twin Grip differentials. Group 19 performance equipment was still an option. See the 1968 AMX for more information on Group 19 equipment.
Big Bad Colors
The three big bad colors of orange, green, and blue were still available, but they now included a chrome bumper instead of the previous color bumpers. Production numbers for the 1970 "Big Bad AMX" cars are not available.
Although 1970 had the least amount of AMX's produced, that doesn't necessarily mean they are more valuable or more collectible. AMX collectors seem to have their reasons why they love a certain type of vehicle, due to looks or nostalgia.
1971 AMX Prototype
Had the 1971 AMX been built, this is what it would have looked like. AMC designer Richard A Teague was pushing for the AMX to be continued, and this is the model he produced. He took his own 1968 AMX, and modified it for the AMC board members, but the idea was shot down. The model features a fiberglass front end, a new interior, and 70 tail lights housed in fiberglass. Although the 1971 AMX was not produced, the board did like the front end styling, and this was incorporated into the 1971 Javelin AMX. This car's owner resides in Jefferson, WI.
