Renault Power Unit Hardware & Software

Abitebeoul said that Renault says F1 engine gained a second over 2016

"The engine itself, between the end of last season to the end of this season, has improved more or less close to one second - when we use it to the full potential, which is not something we would do permanently - which is simply huge.

I have readen that only two MGU-Ks allowed next season which is Renault's headache of the season.

That's correct.Here's the list, for 2018 parts without penalties:
3x ICE
3x ERS-H
3x TC

2x ERS-K
2x ES
2s CE

Any time a new part is brought in over these limits, it's a 10-place penalty. Further introductions attract a 5-place penalty.

Could it be that Renault Pu is already at Ferrari level, but MGU-K is the differentiator?

It sounds like the MGUK is more of a weight issue and not a power one.

Not that I think that the Renault PU is at Ferrari level but the article said "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."

This is in reference to reverting to 2016 MGU-K for 2017 season, and not related to 2018

Right, they ran the 2016 MGU-K model all of 2017 from what I read. Reports say, they're still having problems with it.

dren said that the 2017 MGU-K was just a weight Advantage over the 2016.

Just and more are two different words. Either way, sounds like Renault are still having issues.

Mercedes 5 time world champions, confirmed!

The general perception is the Merc is indestructible. We've seen in 2016 where they've had problems. They had to use Certain engine mode longer than they wanted and that ended up in failures for Hamilton. I think Ferrari threw it away this year, it was their's to lose and they did just that. SO I don't think it will be as easy as that.


Not only are the PU number restricted further this year but over the last couple of years a team, like RBR, could start from the back on certain tracks and still finish 6th or higher. If both McLaren and Renault are more competitive next year it will make it much harder to do that, Hence, the price for a PU penalty will have gotten more expensive.

I disagree with you
Most realiable unit of 2017 Renault Pu was Mgu-k
I am not sure Renault switched 2017 mgu-k but only One Renault powered driver used 4th mgu-k 2017 season
Renault's headache of the season was mgu-h
According to news Renault has already solved vibration problem which caused main factor of mgu-h issue

The 2017 mgu-k was never used in 2017. Red Bull had to make an adaptor for the 2016 mgu-k to work on the 2017 PU which was 5kg heavier. This lighter mgu-k is apparently what Renault are still having issues with on the 2018 PU.

By all accounts Renault's 2018 PU if it works will actually just be a 2017 unit with everything working reliably. Do not expect any significant power gains as Renault are just looking for reliability.

If renault can finish the season with 4 PU in 2018, that a huge achievement from them from the reliability side. I expect in the winter testing they will bought 20hp at minimum from combustion refinement and New fuel from BP. Dont forget that BP is also New player in this formula. Next season would be very interesting

If I was a f1 engine designer I wouldn't care of reliability for 4 engine per season and I would go for pure performance. In the last season we have seen that how a fast car with penalties could make its way to near poduim.
