Sebastian Vettel admitted that he is concerned that Formula One will lose some of its "excitement" when the sport switches to V6 engines in 2014.
Vettel is the latest to voice his concern about the impact the smaller engines will have on Formula One, suggesting that the new cars won't be as exciting to drive as their predecessors.
I am a bit sad because my first test in F1 was in a V10," said Vettel at the Autosport awards ceremony.
"I remember that test, and then we went to a V8 a year afterwards. When I had my second go in an F1 car I could tell the difference.
"I just hope that we are not going down from a power point of view. We will lose the revs which I think is a shame - because it is a new direction that we go into and a new technology.
"I also still remember the first time I went to see F1 was in 1992, it was raining and only free practice in Hockenheim. The cars were only coming out for installation laps, and just to hear the sound of the car coming around, to feel it in the ground; they are the first memories I have.
"I just hope in the future we will not lose this excitement. I think the cars need to smell, the cars need to be loud, it needs to give you something that you don't forget."
Under the new regulations, Formula One is entering a new era and Vettel believes it is impossible to predict at the stage how next year will pan out.
"I think it is very difficult to know, every team and every engine manufacturer probably has an idea of how it should turn out, but it is a surprise at this stage," the German continued.
"Next year getting the cars on the track for the first time will be very interesting and then we see how many engines blow up or not."
