Compressed-air vehicles are comparable in many ways to electric vehicles. Their potential advantages over electric vehicles include:

  • Slow cyclic movement (10 to 60 cycles/minute),
  • High torque for minimum volume,
  • The sequential mechanical design of the engine is simple and robust
  • They do not suffer from the effect of corrosion of batteries in hot, humid climates
  • Low manufacture and maintenance costs as well as easy maintenance are claimed
  • Compressed-air bottles can be disposed of or recycled with less pollution than batteries
  • The tank may be able to be be refilled more often than batteries can be recharged
