C.A.T.® technology or Compressed Air Technology® is a patented, proprietary technology developed by Guy Negre to run his engines with compressed air. To date, over 32 worldwide patents have been filed for the first zero pollution motor developed by MDI. Although the technology is new, the idea isn't completely unknown to Formula One fans or those interested in engine technology. In fact, every Formula One engine starts with a shot of compressed-air as an Energy-Booster. Guy Negre has simply extended its potential by turning it into a single source of energy for running the engine.
