One-off Build #31 - Finished

Recommended Posts

First of all this car isn't a true One-Off build. According to amx3.org original 6 cars were build for AMC. 3 additional car were build on original chassis including a spider. In the 1970 Bizzarini build and sold around 30 cars as the Bizzarini Sciabola.

Here the timeline for the AMX_K or AMX3 project (Source AMX3.org)

  • May 1967 AMC gave Richard “Dick” Teague, the head of design at American Motors, and Bob Nixon, his chief designer, are given the go-ahead to propose a mid-engined prototype. The project was called AMX/K and it convinced AMC management of the idea to actually build a mid-engined sports car, the AMX/3.
  • March 1968, Meyers and Teague went to the Geneva Motor Show to meet Giorgetto Giugiaro and to ask him for a proposal.
  • April 68 photos exists from the Dick Teague design team that present the in-house AMX/3 design. The actual design team included Bob Nixon, Jack Kenitz, Eric Kugler, Dick Jones and Gary Guichard plus clay modelers Chuck Hosper, Keith Goodnough, and Howard Clark. At the same time Fred Hudson and Bob Nixon execute the AMX/2 design from a shape sketched by Dick Teague in ’68.
  • 3rd quarter of 1968 Bizzarrini S.p.A. has to close down for financial reasons, and a trustee is appointed for the bankruptcy.
  • 3rd quarter of 1968 Salvatore Diomante establishes AutoOfficina SD in the 1965-1968 Bizzarrini S.P.A. Livorno factory and begins the process of purchasing all Bizzarrini tooling, parts and inventory out of the Bizzarrini S.P.A. bankruptcy.
  • October 1968 Giugiaro, Bizzarrini and Diomante completed the Manta.The car is presented at the 50th Salone dell’Automobile in Turin, Oct 30th – Nov 10 1968.
  • November 1968 the Giorgetto Giugiaro Styrofoam proposal arrived at AMC headquarters for the AMX/3 design competition.
  • Parallel to (and prior to) the design competition, AMC was looking for ways to outsource the engineering and production of the new car.
  • Reported that Hal Siegel of AMC handed the initial job of creating the first prototype body to Sergio Coggiola of Carrozzeria Coggiola in Torino. Coggiola started the body but backed out and left the first body unfinished so Siegel turned the job over to Bizzarrini and Diomante. (Confirmation of this report is needed from another source.)
  • Reported that Karmann was hired to oversee the AMX/K project. Karmann commissioned ItalDesign to manage the project. ItalDesign (Giugiaro) commissioned Bizzarrini to develop the chassis for the first car probably some time in mid-late November 1968.
  • December 5, 1968 Bizzarrini first meetings with KONI engineers with drawing of the front shocks.
  • December 24, 1968 Bizzarrini drawings for the front springs for KONI.
  • January 30, 1969 Bizzarrini drawings for the rear springs and shock absorber for KONI.
  • February 1969 the fiberglass mockup AMX/2 is shown at the Chicago Auto show. This is a “teaser” project to draw publicity for the forethcoming AMX/3.
  • March 1969, BMW and AMC signed a $1.5 million DM contract (about $800k USD) to test the quality of the Italian prototypes, improve them and verify its performance. BMW Project E18.
  • June 1969 the first prototype was sent to BMW for testing. “BMW engineers found the scope of the tested prototype No. 1 to be far too weak and yielding.” The first prototype is built in Via della Padula in Livorno by Autofficina SD but it was finished by the crew of Diomante at BMW factory. The second prototype Chassis No. 02 is built at ItalDesign in Nichelino, Torino.
  • July 25, 1969 The custom pre- and final silencers were developed under special order SK 5998.01 and SK 5998.02 by Friedrich Boysen GmbH & Co. KG of Altensteig, Germany. Engineers at Boysen kindly provided scans of the original production drawings for these commissions.
  • October 15-23, 1969 BMW exchanged the Girling system on prototype Car #1 with German ATE components. The work was performed at Alfred Teves (ATE). and included the installation of a larger master cylinder, dual vacuum operated brake boosters T50-29-11 (subsequent cars were to receive single T51 boosters), four-piston calipers M4-40 and ventilated discs in the front, and twin L38 two-piston calipers in the rear. The handbrake handle was taken from a BMW E3/E9  (Bavaria/CS coupé).
  • December 5, 1969 BMW test report the torsional rigidity “of prototype No. 2” noted that the AMX/3 had a 50 percent higher stiffness compared to a benchmark Mercedes-Benz model.
  • February 1970 Diomante moves his busness from Livorno and starts Autocostruzioni SD in Moncalieri. Giotto operates under the corporate name Z2 and operates as an external consultant for Autocostruzioni SD. Car #2 is finished here and car chassis 3-9 are built here.
