The first-generation AMC AMX was a two-seat, V-8-powered coupe built from 1968 through 1970. It shared much with AMC’s four-seat Javelin, but it was a distinct short-body model, not simply a Javelin trim package. AMC built 19,134 of these AMXs across three model years—a short run that helps explain their rarity, while the car’s engines, performance equipment and unusual place in AMC’s lineup explain why it merits attention.
What made the first-generation AMX different?
AMC unveiled the AMX in February 1968 as part of an effort to attract younger performance-car buyers. It drew on the styling and equipment of the four-seat Javelin, but its shorter body and two-seat cabin made it a separate kind of car. The American Motors Rambler Club describes it as the only mass-produced American two-seat sports coupe besides the Corvette at the time; that is the club’s characterization, not an independently verified market census. The club also gives a starting price of $3,245 in its historical account. American Motors Rambler Club
The distinction matters when discussing the name. AMC ended the separate two-seat body after 1970 and applied the AMX name to a four-seat model based on the longer Javelin body. “First-generation AMX” or “1968–1970 two-seat AMX” refers specifically to the car covered here.

How rare is the 1968–1970 AMC AMX?
AMC’s production totals were modest, especially beside the Javelin in 1970. The American Motors Rambler Club and the AMX-perience technical archive report the following model-year figures; the club’s page does not state a publication year.

The figures show both a limited run and a changing mix of engines. Hagerty puts 1970 Javelin production at 8,496, compared with 4,116 AMXs that year, illustrating how much less common the shorter two-seat sibling was. Hagerty’s 1970 AMX overview
Which engines came in the AMX?
The 1968–1970 two-seat AMX was V-8-only, but its engine lineup changed during the run. The horsepower ratings below are those reported by the American Motors Rambler Club; output should be read by model year and engine, not treated as one rating for every AMX. American Motors Rambler Club
| Model year | Available engines and reported output |
|---|---|
| 1968 | 290 cu. in., 235 hp; 343 cu. in., 280 hp; 390 cu. in., 315 hp |
| 1969 | 290 cu. in., 225 hp; 343 cu. in., 280 hp; 390 cu. in., 315 hp |
| 1970 | 360 cu. in., 290 hp; 390 cu. in., 325 hp |
For 1968, the club identifies the 390 as a four-barrel X-code engine. In 1969, AMC dropped the two-barrel 390 offering; for 1970, the 290 and 343 gave way to the 360 and 390. Hagerty likewise describes the 1970 360-cubic-inch pushrod V-8 as the common configuration, rated at 290 bhp, with a 325-hp 390 optional. American Motors Rambler Club · Hagerty

What did the 1970 Go Pack add?
Performance was not just an engine choice. On the 1970 AMX, the Go Pack grouped equipment that made the car better suited to putting its V-8 power to use. Hagerty lists power front disc brakes, a limited-slip differential, a handling package, heavy-duty cooling, ram-air carburetion and related hood treatment among its contents. Standard 1970 brakes were drums; the front discs were available with the Go Pack. Hagerty’s 1970 AMX overview

The underlying suspension followed the Javelin’s general arrangement: coil springs and A-arms at the front, with a live rear axle, leaf springs and tubular shocks at the rear. Shared components did not erase the AMX’s identity; the two-seat body, shorter proportions and performance options gave it a distinct role. Hagerty
Special editions and AMC’s performance publicity
California 500 Special
The American Muscle Car Museum describes a 1969 California 500 Special finished in Big Bad Green with a black stripe and a 390 V-8 rated at 315 hp. The museum connects the edition to AMC’s Riverside 500 pace-car promotion. It says the dealer network is thought to have sold 32 examples, so that figure is an estimate rather than a settled factory production count. American Muscle Car Museum

Hurst SS/AMX
The Hurst-built SS/AMX is another distinctive variant noted by the American Motors Rambler Club. Its exact production count is uncertain in the cited enthusiast material: the AMX-perience production archive lists 52, while another enthusiast overview gives 53 with a question mark. Those conflicting figures do not establish a definitive total. American Motors Rambler Club · AMX-perience production archive
Speed-record campaign
The American Muscle Car Museum reports that two AMXs prepared by Craig Breedlove’s Spirit of America crew set 106 world speed and endurance records at Goodyear’s Texas track before the cars went on sale. That figure belongs to the museum’s account, but the campaign offers a vivid example of AMC promoting the car’s performance rather than relying on styling alone. American Muscle Car Museum

The AMX stands out because it combined qualities that are easy to overlook when AMC is remembered mainly for practical cars: a compact two-seat body, V-8 power throughout its first-generation run, year-specific engine choices up to the 325-hp 1970 390, and available performance hardware such as the Go Pack. Its close relationship to the Javelin explains how AMC could share engineering and styling cues; its shorter body and two-seat layout explain why it was not merely another Javelin variant.

It also has a clear historical boundary that can get lost in shorthand: the 1968–1970 AMX was a two-seater, while the AMX name continued afterward on a four-seat Javelin-based model. Combined with its 19,134-car three-year production total and period performance promotions, that distinct identity makes the first-generation car more than a footnote in the American muscle era. Hagerty notes that the AMX was not eligible for SCCA Trans-Am, unlike the wider AMC performance story associated with the Javelin. Hagerty
What to know when identifying an original AMX engine
Engine and transmission production breakdowns can describe how many cars were built with a given configuration, but they do not by themselves prove that a particular engine is original to a particular car. In the American Motors Rambler Club feature, club technical editor Jeff Reeves says it is “virtually impossible to determine whether a particular engine was originally installed in a particular vehicle.” The same feature quotes parts supplier Eddie Stakes: “AMC engines contain no identification that directly corresponds to the car that AMC installed them in.” Casting and date information may help identify an engine, but it does not establish factory installation in an individual car.
