"We are a sport that is famous for being loud and dangerous," Red Bull driver Vettel told the German newsmagazine Focus.
"We run the risk of losing the essence of motor sports," he charged.
When asked about the new, quiet and V6-powered engines, Vettel responded: "I would prefer a V10 or V12 with 1000 horse power -- lots of power.
"I would like to drive cars that are as fast as they can be -- I need to feel as though I am taming a dragon or a beast," he explained.
"Compared to last season, this impression has diminished an awful lot," said Vettel, who has struggled in 2014 alongside his new teammate Daniel Ricciardo.
"The car does not know what I want," explained the 26-year-old, referring to the Adrian Newey-penned new RB10 and his troubles at the wheel.
"Under braking and in the corners I have an absolute lack of confidence," added Vettel.
