The 275 GTB #05161 GT

The S.E.F.A.C. corporation (Societa Esercisio Fabriche Automobili e Corse) was founded the 23rd of may 1960 by Enzo Ferrari and Michel Paul-Cavallier, who was made its C.E.O. He was an important french industrial (foundries of Pont-a-Mousson) with a passion for sports and racing cars. He would regularly go to Maranello for meetings with Enzo Ferrari and his engineers to finalized different projects, like a car based on the engine and the bodywork of 250 GT.

This prototype of the 275 GT/B #05161 GT on the chassis and powertrain of the 250 GT and the aluminum body will be studied in the wind tunnel and will become the first prototype 275 GT/B delivered 03/20/1963. A real rear ressemblance with the 250 Lusso and the 250 LM #05149 (only 5 cars apart), the 250 GTO 1964 will come out a year later
In 1963, 2 cars will come out of Maranello with a similar body line : the 250 LM #5149 and the 275 GT/B #5161 GT.

The study of those 2 prototypes will not be in vain, since Ferrari will use the same roof on the rarissimes and last GTO of 1964

The 275 GTB #05161 GT

In spring of 1963, during testing at Fiorano, the #05161 GT will crash and subsequently given to Michel Paul-Cavallier. After his death, it will be sold by the garage of Hughes Hazar of Nancy to the Colonel Dick Mitchell of the USAF base of Rosieres-en-Haye.
Gone to the United States, in the mid sixties it will be made into a cabriolet and will stay in a garage in Sacramento CA. In the nineties, it will go back to Europe to finally be restored to its original configuration.

The "Competizione Speciale"

Michel Paul-Cavallier, unfortunately, will not see the projects coming to fruction with the fabrication of four 275 GTB Speciale competition, leighter and faster, numbers #06701 / #06885 / #07185 and #08249.

They will be Special Competition. "Competition" in quotes because F.I.A. and C.S.I. refused cars more than 5% less weight, which was a big problem because the standards often changed. Nonetheless these four special 275 GTB were built for racing in the continuity of the 250 GTO, each with different patterns, but with common :
    - weighing 150 to 200 kg less than the original model
    - few millimeters alluminium bodywork
    - engine type LM 250 213 ribbed four attachment points
Shortly after the 4th Special 275 GTB Competizione, emerge twelve 275 GTB/C on the 9000 series, with the four Special Competition, they are the only car to have a 250 LM engine type 213.
