Ferrari president Luca di Montezemolo says the proposed Formula One engine changes for 2013 are "a bit pathetic".
In December the World Motor Sport Council approved plans to drop the current normally-aspirated 2.4-litre V8 engines for energy-efficient 1.6-litre four-cylinder turbos.
The new system is set to run in conjunction with KERS, which will make its return to the sport in 2011 after a one-year absence.
Formula One supremo Bernie Ecclestone has already voiced his displeasure at the proposed engine regulations and now di Montezemolo has also expressed his discontent.
"We will not be building any (four-cylinder engines) for our street cars," he told Auto Motor und Sport.
"For the top class of racing it sounds a bit pathetic. Why couldn't we have a V6 turbo? We should not confuse affordable with cheap."
Di Montezemolo hopes to delay the introduction of the new rules but admits that he would need support from the other teams to make that happen.
He added: "If there is the slightest possibility to delay the four cylinder, I will look for it. We see a chance. We need unity."
