A nedoumice mi potiču od recimo, inače vrlo preciznih ADACovih analiza (a i drugih) koje kažu da je 1.4 16V 75KS vrlo tih motor.
A recimo isti taj isti 1.4 16V ali sa 80 KS koji se ugrašuje od 2007 na istom ADAC testu daje puna 3 dB više, što je tačno duplo više.
To me je navelo da pomislim da je taj od 80 KS aluminijumski, što bih svakako izbegao.
Desmo, znam za taj spisak sa wikipedije, ali on nije sasvim precizan a i u suprotniosti je sa ovim što je PaulGT rekao.
edit: evo da ubacim i ja nešto:
