Porsche R7 RSR Prototype
This R7 prototype finished the 24 Heures du Mans 4th overall in 1973
Unlike the recently sold (for 2 million) '93 RSR that never turned a wheel, this is the real deal. Car 46 finished the 24 Heures du Mans 4th overall in 1973 and went on to race in 5 of the 10 round World Championship.
After its work career, it continued to be raced, first in America, and then in Europe, before being returned to its original tail and Martini colours. It's now owned by collector Kenny Schachter
In 1973 eight 911 Carrera RS 2.7s were delivered to Porsche's race shop and after modifications, eight RSRs were born.
The modifications included a 3.0L engine with slide valve injection, center lock wheels, long distance brakes front and rear, aluminium doors and front fenders, prototype seats, short trailing arms, special suspension with titanium springs.
The RS ducktail was modified into a continuation curving onto the arches, an appearance that gave the cars the nickname of 'Mary Stuart cars', due to the resemblance to the collar made popular by Mary Queen of Scots.
