In 1970 the executive suits at AMC were gallivanting around Monza waiting for this American mid-engine prototype to prove itself on the track and with its top speed. The lead designer/ builder seemed to embellish the statistics for the car as he claimed it would do 160mph. With the impressive number certainly a selling point for the American market, the suits stood there and watched as the AMX/3 rounded the corner and in a rush of speed and fury, disappeared. That is when Giotto Bizzarrini turned to the suits and asked if 170mph was fast enough for them.
To go 170mph even today is impressive as forces of nature begin to plot your demise through wind, heat, and even gravity. With what would be seen as a simplistic suspension, steering and tire engineering by todays standards, made feats of this kind that much more difficult in 1970. The AMX/3 was built around the AMC 390 c.u. in motor producing 340hp and 430 lb-ft of torque connected to a 4-speed transaxle.
