eh eh ,
It's coming out!
Revealed to the press today.
The secret has been well kept, here is a new smashing:PSA Peugeot Citroën launches the battle for low-cost hybrid vehicles
This innovative compressed air solution would be marketed in 2016.
22 Janv 2013 The Echoes
In front of all the existing models or in project of hybrid cars, PSA Peugeot Citroën tries a small revolution with "his" solution: the hybrid technology ... with compressed air. No longer grafting an electric motor, with a heavy battery, on a heat engine, it is this time to marry a small gasoline engine with compressed air. A bold path, but which relies heavily on proven components. And which aims to significantly lower the cost price of these vehicles. A challenge for industry specialists, including Toyota, the father of the Yaris.
PSA has developed a new hybrid vehicle concept combining a gasoline engine with a compressed air engine, but without the traditional electric battery. - MONIQUE DUPONT-SAGORIN
If the compressed air was already stored on submarines since the Second World War, no one has for the moment engaged in this technology en masse in the automotive world. Philippe Varin, CEO of PSA, unveiled Tuesday this new industry, Hydrid Air, developed in the secret with Bosch, for nearly two years, on four prototypes that have already accumulated 20.000 kilometers. In presenting this work, Guillaume Faury, director of research at PSA, said he wanted to market these first vehicles from 2016, on both brands of the group, although "it remains to cross the stages of industrialization."
At the next Geneva Motor Show in March, Peugeot and Citroën will unveil the first models equipped with the "Hybrid Air". Particularly suitable for cars of segments B and C and utilities, this option could interest for example the replacements of the current Citroën C3 and Peugeot 208. In addition, the General Motors ally could acquire it on the shelf, especially for Opel: "Beyond projects already launched with GM, we will continue to look at innovative topics with them in 2013, so things are open", says Guillaume Faury.
Hybrid low cost?
With its new philosopher's stone, will PSA go so far as to invent the "low cost hybrid"? For the moment, its avowed aim is to develop models emitting about 70 grams of CO2 to 100 kilometers (for now, only 100% electric vehicles do better), consuming 30% less fuel than a version thermal and displayed at less than 20.000 euros. While its current specialty, the diesel hybrid starts rather beyond 30.000 euros. The new project is not aimed at the same customers and could interest, in addition to Europe, emerging countries such as China.
Convinced of the interest of the formula, the State put its hand in the pocket, investing as early as the upstream phase of the project, via the General Commissariat for Investment (CGI), taking a blocking minority in a joint venture led by PSA (Technoboost). "This technology is robust, affordable, easy to maintain, its market will go far beyond Europe," according to Bernd Bohr, head of Bosch. PSA refuses to give an idea of its past and future investment.

You must of course read 70 grams of CO2 per kilometer (one km).
The idea of Guy Negro finally implemented by a great builder?
Yes and no, but the principle is not exactly the same. It is a vehicle essentially essencel first ....
It is in the urban cycle, when the engine runs for nothing, that its energy would be used to recharge a tank of compressed air, idem braking or cynetic energy would be used to reload the tank ... Chatelot had this idea there just a few days ago
Seen in the French newspaper 2 (you can see it on TV5 in a few minutes).
