In an outburst last week against the sport he heads, F1 chief executive Ecclestone said the farcical events of the opening test at Jerez proved his fears about the energy recovery-powered V6 era were founded.
He even dismissed the argument that F1′s new regulations save fuel, insisting: “Mercedes are taking 23 trucks with them everywhere. If they really wanted to save fuel they should stop that”.
Former triple world champion Lauda, now the chairman of the Mercedes team, hit back at Ecclestone’s comments in the German newspaper Bild.
“I don’t understand what Bernie said,” the great Austrian started.
“The decision to go with the new engines was taken jointly, by everybody, five years ago. To criticise now makes no sense,” said Lauda.
