Engine development tokens scrapped in 2017

NEWS STORY
04/02/2016

Introduced in a bid to curb in-season development, and the resultant costs, the token system was unpopular and unnecessarily complicated.

The tokens allowed engine manufacturers to update various components, which all had a specific (token) value.

However, to add to the confusion, not only was the amount of tokens decreased over the six years the rule was due to be in place (2015 - 2020), there was a system whereby certain parts could not be updated after a certain point.

Initially the sliding scale would have seen manufacturers allowed 25 tokens this season but following a meeting of the engine manufacturers last October this was raised to 32.

At the same time restrictions on those areas in which development was banned this year, including upper/lower crankcase, valve drive, crankshafts, air valve systems and ancillary drives, were lifted.

At the time, the move was particularly welcomed by Renault and Honda, as the 28 February deadline was also removed thereby allowing development in to the new season.

The decision to scrap the token system was revealed by Renault's Cyril Abiteboul at yesterday's team unveiling.

"The token system is being removed," he told journalists. "One of the reasons we have all agreed to do this is that we all need the performance of the engine to converge.

"An F1 that is dictated by the performance of the engine is not good for anyone," he added. "It is not good for Mercedes, it is not good for Renault, Ferrari... we all have interest to change that.

"We have decided, also for the public, to stop the public being confused between the penalty system and the token system, we have decided to simply remove the token system."

And in case you'd forgotten how absurd it was.

"Is this true? Or is there something else going to pop up, even worse then this token system?

I bet Newey will be happy!"

"Why wait 'till 2017. I don't understand why it is not lifted as of this moment. Did someone say left's have another bad year THEN we'll change it?"
