In 2016, every engine manufacturer had to develop the car with a limited number of engine tokens. But for the 2017 season, the token system has been scrapped. This leaves the engine manufacturers freedom to upgrade their engines throughout the course of the season. However, Renault Sport Racing president Jerome Stoll has raised concerns about the cost of the hybrid engines. he believes that the amount spent on upgrading the engines should be controlled. “Hybrid is something which is interesting, the problem we have at the end of the day is the cost of the technology,” said Stoll. “We have to take care of the costs and ensure that there is a return on the investment that we’ve made. And the costs have deviated a lot. We have to see how we can curb a little bit or cap a little bit the costs of development for each car maker.”
While fans have been clamouring for the sport to go back to simpler and louder engines, Stoll and FIA president Jean Todt are of the opinion that technological advancements are the key to gaining the interest of manufacturers. According to Stoll, manufacturers are in the sport for technological reasons. “The fact that we pushed among the others for the introduction of the hybrid system in the engine is also because it shows that even in the competition of F1 we can work for the environment by reducing the consumption by 30-40 percent. It’s something that illustrates that you can be in this competition without being somebody who wants to kill the planet. You like the competition, you like the passion, and you can work also in a way where everybody wants you to work.” said Stoll.
Red Bull’s motorsport advisor Dr Helmut Marko says that nobody would buy the idea of engines being made loud due to artificial means. He said “We need to have proper engines again – engines that are a violent force with noise that makes you feel exactly that. The driver has to be the crucial factor again, not the engineer. This has to happen. I want to admire a person who’s doing an extraordinary job.”
