Och de går utmärkt på E85

Citat:
The 2CV was produced from 1949 until 1990 and sold almost exclusively in Europe. At the time of its introduction the car had an engine capacity of 375cc, a maximum power output of 8 horsepower (DIN-HP) and a top speed of 65 kilometres an hour (40 mph).
In 1954 the power was tuned up to 10 HP, which brought the top speed at 80 kilometres an hour (50 mph). In 1974 the power output rose to 24 HP, with a top speed of 102 kilometres an hour (63 mph). Later models had an engine capacity of 602cc, a maximum power output of 30 HP and a top speed of 120 kilometres an hour (75 mph).
500 kilograms
In spite of the much higher performance (an almost doubling of engine capacity, 4 times as much power output and a top speed almost twice as high) the weight of the hippie car remained the same at about 500 kilograms (sources: 1,2,3)
Today, there is not one car which comes even close to these figures. The smallest model of Citroën now on the market, the C1, weighs 810 kilograms (despite the use of lighter materials). The Citroën C1 has an engine capacity of 998cc and a maximum power output of 68 HP, and it does 157 kilometres an hour (98 mph).
8 x more power
Compared to the first 2CV models, the weight of the smallest Citroën today has almost doubled, while the top speed more than doubled and the maximum power output rose by a factor of eight.
Surprisingly, the fuel consumption remained more or less the same. The C1 consumes 4.6 litres per 100 kilometres (61 miles per gallon), the 2CV consumed on average 4.4 litres (64 miles per gallon).
It is obvious that the engine of the C1 is many times more energy efficient than the engine of the 2CV, since the latter needed the same amount of fuel to power a much lighter and much slower vehicle.
In other words: if we would apply this modern technology in a car that is as light and slow as a 2CV from the fifties, we would now drive cars that scarcely burn any gasoline. Unfortunately, all technological progress was devoured by more weight, more power, more speed, more comfort and more electronics.
Resonemanget ovan haltar såklart eftersom C1:ans bränsleförbrukning vid toppfart av är mkt högre än 4,4 l / 100 km medan 2cv mestadels körs fullgas.
