Engine parity key to F1 future

Formula 1 supremo Bernie Ecclestone has made calls for a partial return to V8 engines, the idea being that two types of power units compete in the sport from 2017, allowing midfield teams to run with a cheaper engine.

The idea has received the backing of teams like Force India, while Red Bull boss Christian Horner said he was open to the concept.

Kaltenborn admitted the idea was worth exploring as long as it means there is engine parity.

"Everybody will agree that Formula 1 has to represent the cutting edge of technology," she told the official Formula 1 website.

"We also all have to accept that the power train has been the major cost driver - and we actually never wanted to get back to these times that power trains cost that much.

"The whole issue was made exponentially bigger by the fact that there was such a big discrepancy between the different power trains - and one dominating so much.

"The concepts that are being discussed are very interesting in view of that.

"The key element has to be that there is parity among the engines."

Kaltenborn also reckons the sport should listen to the fans when discussing significant rules changes to be introduced in the future.

"You also have to bring the fans into this discussion," she added.

"No matter what you think about the noise being relevant or not, any issues brought up by the fans - and if there is a chance to change this - then bring them in and find out what they want and then let's see if it is doable."

Formula 1's Strategy Group is due to meet next month to discuss, among other things, the sport's plans for 2017.
