Renault's Cyril Abiteboul has revealed that the French manufacturer aims to continue its ascent in the engine department as the company is preparing a completely new platform, including novel technology that has not yet been seen on the track.

Thanks for this info epo, i reckon that`s going to be quite a handicap to the Renault powered cars until the new 2017 spec MGU-K is fitted. Just like Honda, Renault can`t foresee everything and failures do happen (insulation in this case) even when the stuff has probably spent hours on the test beds.epo wrote: ↑25 Mar 2017, 14:53Seems everyone on this forum is to focussed on McLaren Honda..
De Renault teams seem to have fall back to the 2016 MGU-K to prevent the issues they had during testing :

A few kg, maybe 5*, more and "less powerful" then the new MGU-K for five races and hardly any headline about it? After the last long three years full of talk about the importance of power pack integration and the interdependence with ERS?"I guess that will be where we will look at that. It's added some weight, so it's a few kilograms on top of what we thought we would be running."
That means the Renault teams will likely have to persevere with the old MGU-K, understood to be around 5kg heavier and less powerful than the new unit, until at least May's Spanish GP at Barcelona.
Taffin admits that power delivery has greatly progressed since the early days of the Power Unit back in 2014.
“Power delivery of the stored energy is now performed around almost the entire lap,” Taffin confessed. “We have reached outstanding levels of overall efficiency. Today, the MGU-K is capable of producing 120kW, which is the equivalent of 160bhp, around almost the entire lap. The moment the driver steps on the gas pedal and we are no longer grip limited, it applies full power. It’s no longer if the driver wants to use it or not. The power is available. It’s all controlled automatically.

Taffin-Autohebdo-google translation"We took advantage of this challenge to go beyond our previous approach and rethink the integration of mechanics into the chassis. The way the organs, subsets of the energy recovery system, battery, Cooling elements are connected to one another, intertwined, for obvious performance reasons, because this is not only achieved by horses of pure power, but rather radical choices have been adopted to reduce the mass and We have also tried to homogenize the temperatures, the temperature and the temperature of the heat exchangers, To obtain the least "hot" sources possible. So far, we had a system of recovery of energy rather low temperature and a thermal V6 rather High temperature, we made a leveling from the top. Wider car? Yes, it helps, but again, engine manufacturers always fantasize about a complete compact, lightest, best integrated and centered powertrain possible with a loss of heat, so horses, as low as possible. All the energy that one can avoid to pass through the radiators turns into power to the wheels."
