The first LN2 car could travel 79 miles (127.58 km) on a full
24 gallon (90 liter) tank of liquid nitrogen going 32 Kmph.
Its maximum speed was over 56 Kmph.
After further Researches, the Efficiency has improved as
Power : 78KW or 104.5bhp @ 97Kmph
400 Liters (106 gallon) gives a mileage of 560Km and weighs
Operating Cost is around 2.4cents per Km( Re 1 per Km)
• Car is much lighter in
• Refilling its tank takes only
• Minimal Maintenance
• Requires a lot of energy
• Gas is so cold that the
moisture in the surrounding air
would condense on the outside
of the tubes.
• Safety issue
• Leakage of N2 leads to prove
Even though the technology is 10 to 12 years old, still it
has not come to the market for two reasons:
• Safety issues have not been sorted out as yet.
• Lack of funds for research.
Why not commercialized?
• A tube within a tube design.
• N2 passes back and forth inside a set of three nested
• By the time it reaches the outermost tubes, the N2 is
warm enough that the exterior wall of the tube
remains above the freezing point of water.
• In a real sense, the more such vehicles are used, the
cleaner the air will become.
• In addition to the environmental impact of these
vehicles, refueling using current technology can take
only a few minutes, which is very similar to current
gas refueling times.
