Doubts on progress and technology

The 2CV: cleantech from the

If you sometimes wonder why more efficient technology does not about more energy cars, you should take a at this collection of Citroën (most of them in foreign from the fifties. the sixties. the and the eighties (more here. here and here ).

These are all scanned leaflets of the legendary hippie car 2CV or Deux Chevaux as the duck or the goat in several countries). In spite of all the high-tech has been squeezed into since then, the 2CV from is still more energy than the smallest model of the car designer today. Why?

If we really want more efficient cars, the 2CV shows us we need not more, but less

The 2CV was produced from 1949 1990 and sold almost in Europe. At the time of its introduction the car had an capacity of 375cc, a maximum output of 8 horsepower (DIN-HP) and a top of 65 kilometres an hour (40 mph).

In the power was tuned up to 10 HP, which the top speed at 80 kilometres an hour (50 In 1974 the power output to 24 HP, with a top speed of 102 kilometres an (63 mph). Later models had an capacity of 602cc, a maximum output of 30 HP and a top speed of 120 kilometres an (75 mph).

500 kilograms

In spite of the much performance (an almost doubling of capacity, 4 times as much output and a top speed almost as high) the weight of the hippie car the same at about 500 kilograms 1 ,2 ,3 )


Today, there is not one car which even close to these The smallest model of Citroën now on the the C1. weighs 810 kilograms (despite the use of materials). The Citroën C1 has an engine of 998cc and a maximum power of 68 HP, and it does 157 kilometres an hour (98

8 x more power

Compared to the 2CV models, the weight of the smallest today has almost doubled, the top speed more than and the maximum power output by a factor of eight.

Surprisingly, the consumption remained more or the same. The C1 consumes 4.6 litres per 100 (61 miles per gallon), the 2CV consumed on 4.4 litres (64 miles per gallon).

It is that the engine of the C1 is many more energy efficient the engine of the 2CV, since the needed the same amount of to power a much lighter and slower vehicle.

In other words: if we would this modern technology in a car is as light and slow as a 2CV from the we would now drive cars scarcely burn any gasoline. all technological progress was devoured by weight, more power, speed. more comfort and electronics.

Part of the extra is the consequence of safety measures. Car always hammer at this and of more safety is a good But, because at the same the speed of the vehicles has raised and higher speeds mean serious accidents, part of progress is negated — like the higher energy is negated by the higher performance.

Moreover, safety belts are the most important reason why deaths plummeted since the and the weight of that mechanism is

Another reason for the higher and energy consumption is the advancement of and electronics. The first 2CVs had a dashboard that was worthy of the The vehicles had no heating or air-conditioning there was not even a fuel

If you wanted to know how much you had left, you had to stop and poke a into the fuel tank. the sixties, the windscreen wipers driven by the wheels — and did not work when the car was not moving you powered them by hand ).
