Directory:MDI Air Car
The MDI Air Car uses compressed air to push its engine’s pistons, can hit 68 mph, has a range of 125 miles, and can be refuelled in a few minutes with custom air compressors at a cost of around $2. Tata Motors of India is planning to produce these zero-emissions cars in 2008.

Following serious commercial misconducts from Mr. Miguel Celades, MDI had to officially stop all relationships with him since 3rd February 2008.
Any reference by Mr Miguel CELADES and/or his companies " Motor de Aire Comprimido S.L. " and "Air Cars Factories SL" and/or his websites "motordeaire . com" and "theaircar . com" , whether directly or indirectly to construction or sales of compressed air engines and/or vehicles using this technology in relation with MDI (Motor Development International constitutes serious charges of unfair competition and fraud.
Mr Miguel CELADES, former MDI agent in Spain and Spanish-speaking countries, is attempting to use the goodwill and success of MDI in order to mislead potential investors for his own benefit.
The first commercial compressed air car is on the verge of production with a recently signed partnership with Tata Motors, India’s largest automotive manufacturer.
How it Works
This engine was developed between the end of 2001 and the beginning of 2002. It uses an innovative system to control the movement of the 2nd generation pistons and one single crankshaft. The pistons work in two stages: one motor stage and one intermediate stage of compression/expansion.
The engine has 4 two-stage pistons, i.e. 8 compression and/or expansion chambers. They have two functions: to compress ambient air and refill the storage tanks; and to make successive expansions (reheating air with ambient thermal energy) thereby approaching isothermic expansion.
Its flywheel is equipped with a 5kW electric moto-alternator. This motor is simultaneously:
- the motor to compress air
- the starting motor
- the alternator for recharging the battery
- an electric moderator/brake
- a temporary power supply (e.g. for parking)
No clutch is necessary. The engine is idle when the car is stationary and the vehicle is started by the magnetic plate which re-engages the compressed air. Parking manoeuvres are powered by the electric motor.
The CAT´s engines can be equipped with and run on dual energies - fossil fuels and compressed air - and incorporate a reheating mechanism (a continuous combustion system, easily controlled to minimize pollution) between the storage tank and the engine.
This mechanism allows the engine to run exclusively on fossil fuel which permits compatible autonomy on the road.
While the car is running on fossil fuel, the compressor refills the compressed air tanks. The control system maintains a zero-pollution emission in the city at speeds up to 60 km/h.

In the single energy mode MDI cars consume less than one euro every 100Km. (around 0.75 Euros) that is to say, 10 times less than gasoline powered cars.
- When there is no combustion, there is no pollution.
- The vehicle's driving range is close to twice that of the most advanced electric cars (from 200 to 300 km or 8 hours of circulation)
- The recharging of the car will be done at gas stations, once the market is developed. To fill the tanks it will take about to 2 to 3 minutes at a price of 1.5 euros. After refilling the car will be ready to driver 200 kilometres. The car also has a small compressor that can be connected to an electrical network (220V or 380V) and will recharge the tanks completely in 4 hours.
- Because the engine does not burn any fuel the car's oil(a litre of vegetable oil) only needs to be changed every 50,000Km.

MDI - Moteur Developpement International
The MDI group is headed by the MDI holding company, based in Luxemburg, which has patents registered in more than 120 countries. The MDI headquarters are located in Luxembourg while the prototype factory is in the south of France, where 60 people are employed.
At the moment the construction of the first serial production factory is being completed, at the same location. MDI also has a Department of International Commercial Expansion in Barcelona.
Guy Nègre, creator of the compressed air engine, is no newcomer to the world of automobiles. In the 1980s he was making airplane engines for passenger planes. After that he moved into Formula 1 and in collaboration with IFP (French Petroleum Institute) developed a revolutionary 12-cylinder W-engine with a rotating valve admission system for competition cars. In spite of its success, the engineers were not sufficiently impressed to look for investment.
Guy Nègre created the MDI (Motor Dévelopment International) society in 1991, based in Luxembourg. The capital came from about 160 investors. To continue the development of the compressed air engine, Guy Negre enlisted the help of CQFD Air Solution, a society he himself created. This society invests in advanced technology systems and includes a team of thirty engineers, amongst whom is his son Cyril, recently returned from a season at the Italian Bugatti camp.
- Zero Pollution Motors - ZPM is introducing the “Air car��? to North America. The vehicle runs on the Compressed air technology (C.a.t.) developed by Motor Development International (MDI), a 15-year old company based in Nice, France, and headed by inventor and Formula One race car engineer, Guy Negre. ZPM is the exclusive representative for MDI in the United States.
- ZEVCAT, INC. stands for Zero-Emission Vehicle with Compressed Air Technology. This California company intends to sell the MDI air car.
- IT MDI-ENERGY - introducing the air car technology to Australia and New-Zealand
