Renault have downplayed concerns that next season's Championship could be won or lost on fuel saving.
Next season fuel efficiency will come into play as fuel will be limited to 100kg per race with teams typically using 160kgs at present. Fuel flow will also be limited.
This has sparked some fears that instead of racing flat out, drivers will be forced to cruise in a bid to save fuel.
However, Renault F1's technical director Naoki Tokunaga is confident the racing will be as "exciting" as it is today.
"In terms of spectacle, I think the races will be different but still be exciting," he told Autosport.
"At a circuit where you are limited to fuel, if you go flat out then you will not make the finish.
"Because you have to save fuel, it means there will be a difference between average power use through races and the maximum power available.
"But that then means if you need it, the maximum power is always available. So if you want to try to use it to get past another car, then you can.
"And afterwards you will then have to make up for the extra fuel used. It will mean more diverse strategies."
Added to that, Tokunaga believes the teams won't struggle to get down to 100kgs of fuel as they already run as little as possible to keep the weight of the car down.
"I have heard the concerns that there will be more people running out of fuel, or that people will stop racing each other to just get to the finish.
"But I don't think there will be more fuel run outs than you have today. We already start races with the lowest fuel load possible.
"We don't want to leave any fuel in the tank when the race is finished, so we have to manage fuel consumption now. It will be the same, and nothing has changed."
