ZL1 racing


ZL1 is the rarest option code ever produced for a Corvette. It means that the engine block is manufactured in aluminium for weight reduction, and a gain of 80 kgs on the front end of the car, in comparison between a complete 427 ci iron engine and the ZL1.

The first European owner for this option was Henri Greder for the 24 Hours of Le Mans in 1970, due to his great relationship with Zora Arkus Duntov. The result was astonish, Henri finished in 6th position overall in 1970. Unfortunately the Porsche managers claimed to the ACO Official saying that the distance effected by the Corvette was not sufficent in relation with the displacement engine. The verdict fall and the Corvette was not classified. But it’s very interesting to note that a GT raced by a private team, finished the 24 hours race just behind two Ferraris 512S and three Porsches prototypes !!!

This racing Corvette (chassis number 194679S706401 has participated six times at the 24 Hours of Le Mans from 1970 to 1975 and is now owned since 1990 by a friend and well known collectioneer.

The Corvette we have prepared is the « replica » of the white and blue racing Corvette which was raced in the 24 hours of Le Mans in 1972, driven by Henry Greder, sponsorized by the french magazine « Femme d’Aujourd’hui ». Our project has the only goal to recreate a famous racing car of the seventies, but in any case to usurp the identify of a vintage racing car still in existence.

The reason we have choosen the 1972 version is for his beauty, but techincally, it’s voluntary that we have opted for the 1971 GR 4 configuration, because the weight and performance ratio was 1.222 kgs for about 550 horsepower which must be the key for us to be very competitive.

The performance is not our only preoccupation, we also would like to respect the GT spirit of the seventies, by keeping the original bumbers, dashbord, door panels on the car. The right paint sheme received a very special care!

It’s now the time to bring the car to the race track and to race ti to show to everybody the quality of our work.
