Toro Rosso boss Franz Tost believes that Mercedes' dominance in the past three seasons stems more from its power unit than anything else.

Indeed, the German outfit superbly negotiated the turn which ushered in the 1.6 litre V6 hybrid era, with its an engineering in the field clearly a step ahead of its rivals.

While Tost echoed the majority of F1's voices in hoping that next year's regulation change would upset the order at the front, he isn't a big believer in Mercedes' demise in 2017..

"If you want to make the show better, first we must equalise the engines," said the Austrian.

"If in 2017 Mercedes still has the edge, then the FIA must freeze the engines to allow the others to catch up the gap.

"Right now we have a championship of engines, because at the wheel of a Mercedes, Alonso and Vettel would have become champions too."

Tost was nevertheless hopeful of the Silver Arrows at least being challenged more often.

"I'm hoping Red Bull and Ferrari can make progress," he insisted.

"Viewers want to see different winners, as well as accidents without serious consequences. I constantly hear from my friends 'Accidents don't even happen at the starts anymore'.

"And we need to get rid of the penalties,"
