Renault permit 'maximum power'

Friday 14-March-2014 01:14

Renault-powered teams will not have to turn down their engines in Australia as the French company believes they have solved some of their issues.

This year's pre-season proved to be a disaster for the Renault runners especially reigning World Champions Red Bull and Lotus.

Both teams were blighted by reliability issues that were blamed largely on their Renault engines.

Therefore in order to do any running the teams were not able to run at full power meaning they never reach their potential.

However, this weekend in Melbourne they will be able to do just that says Remi Taffin, Renault's head of trackside operations.

He told Autosport: "We were behind schedule on some of the items we wanted to have on the car, which prevented us to run to full potential.

"But I think we are now sorted and we will be able to see how it will go with maximum power."

He added: "It's getting better, but until we win it's not done. It's not because we are ahead of schedule that we have [had] to review our plan and lower our targets.

"We will not be happy until we win a race."

He is, however, confident that any software changes Renault made between the final test and Australia will not have a negative impact on reliability.

"The main issues we had with power units was due to the nature of how we control the engine and the boost pressure, and how we manage knock basically - which is the step to gain some more performance from this kind of engine," he explained.

"It is fair to say that when you are late, you are late on everything. So we maybe suffered a bit of lack of experience in how to deal with this situation.

"We had to be very cautious. We did not have at that time the proper software to prevent this kind of thing.

"But I am not worried about that one now. It is basically giving us some reliability confidence and also some performance confidence."

As for concerns that none of the Renault runners practiced starts during pre-season, Taffin believes the cars will have no issues leaving the grid.

"We will be OK to do some starts [from the grid].

"We've seen some good [practice] ones [in testing], it's consistency we need.

"If you look back at the start of the V8s, you had some very bad starts from some of the teams at the start of the year, so bad starts are related to the car system itself, which the power unit is part of.

"There are plenty of configurations. Eventually, we will find one that works."
