Read the full story on French inventor Guy Negre and his company, Moteur Developpment International's Compressed Air Car concept featured in Automobile Magazine online.

Manufacturing vehicles that run on compressed air is clean, cheap and easyor so the thinking goes, for a handful of niche manufacturers. Can compressed air save bad air quality and choked streets?

AI Quick Summary This article from 1971 discusses Mickey Thompson's Thermocharger, a system that uses compressed air to supercharge engines without mechanical pumps, pioneered in 1971.

The idea of using a compressed-air engine, especially in a lightweight city car that didn’t need continent-­crossing range, felt quite plausible.

With modern technology, we can often revisit a clumsy, old idea and make it more efficient. Such is the case with compressed-air supercharging.

A fully functioning compressor is necessary for the air-conditioning system to provide peak performance. On most cars, A/C compressors are driven by an engine-accessory belt.

Turbocharged engines output more horsepower, and an intercooler is an often overlooked part that could help you raise the efficiency of your engine.

Running under typical circumstances, your car’s engine sucks in anywhere from 150 to 400 cubic meters of air every hour.

Though the details of safely propelling a road car with a compressed-air engine are ­challenging, the basics are easy to understand.

A ­former engine developer for Formula 1, Negre began work on his air engine in 1997. By 2004, with a raft of patents under its belt, the MDI team was showing off working compressed-air car (CAC) ...
