[escepticos] Consumo de combustible

[Santiago Arteaga <arteaga@...>]

	Hola, por azares de la vida he ido a dar con mi terminal en 
http://www.greenpeace.org/~climate/industry/reports/smile.html
y en este sitio nos cuentan esta curiosa historia. Digamos que 
experimento una gran desconfianza... ¿alguien sabe algo sobre el
tema?

SmILE - Showing Car Companies How it's Done 

Greenpeace is committed to the eventual phase out of fossil fuel, 
both in energy use and in transportation, Traffic consumes 60% of
world-wide oil production and must be addressed if we are to halt 
climate change, 

New cars are now produced at the rate of one per second, The average 
car pelts out 4 times its weight in CO2 every year, Car numbers, 
poor emission standards and road building are an environmental 
outrage. 

As long ago as 1981 , the prototype Renault Vesta was unveiled with 
a fuel consumption aimed at less than 3 litres per 100km, or 78mpg, 
In 1993 Greenpeace 'borrowed' the Vesta from a museum, and publicly 
humiliated Renault at the Frankfurt car-show for its lack of 
commitment. 

The French government gave Renault and Peugeot $l80 million to 
develop the low consumption vehicles, The Vesta was supposed to be 
launched for production in 1990. It never happened. 

Greenpeace took an average small car, a Renault Twingo, and cut its 
fuel consumption in half, The Smile : SMall, Intelligent, Light and 
Efficient. This car is what the motor industry said could not be 
produced for at least two decades! 

Smile could have been adapted from any of the small cars currently 
on the market. It proves that manufacturers are simply not trying 
to reduce emissions 

The Renault Twingo we started with now has better aerodynamics and 
a high output, low capacity supercharged engine. This is 'drop in 
technology' - it is not experimental or under development, it can be 
used RIGHT NOW! 

Greenpeace has displayed Smile at several motor shows in 1996 and 
1997, But the motor industry is not happy. The British Newspaper 
'The Independent' said, "Why is the world's motor industry not 
willing to produce a car like this?" Why indeed? 

How the engine reduces fuel, not power: The most frequently used 
operating point is matched to the point of highest thermal 
efficiency, and extra power is delivered when needed from a 
supercharger. 

The engine is only 360cc, yet the smile performance equals or 
exceeds the 1.2 litre Twingo. Independent experts have verified 
that it is just as robust as normal, larger heavier engines.
