Are there any significant changes with this new 2019 Renault power unit I wonder?
The whole unit is apparently a complete revamp. The design has started in 2017 and has been running on dynos throughout 2018.
The thing is Renault seems to have some power available but the problem they foresaw a bit ago is that their engine topology just couldn't handle it, thus why the Spec-C was less powerful than expected and also less reliable.
We'll see how it goes.
Although Abiteboul doesn't directly speak it out (so political...) he was only limiting his remarks to the Renault factory team.
He said Renault couldn't get more power out of the spec C....with BP/Castrol.
He does not, deliberately, mention in any way that the Spec-C was more powerful with ExxonMobil.
For the spec B the BP/Castrol seems to perform better then with ExxonMobil.
That was a fact he didn't forgot and rubbed it in to everybody listening.
But with 2 different strategies its comparing apples and pears. Red Bull ran the engines on or over the design limits to score podiums (and subsequently engine failures) rather then Renault who took a defensive approach and focused on scoring points.
According to Abiteboul it was the architecture design limits of the (current/previous) engine concept, no further evolution possible, that made Renault decide to build an al new engine (concept) for 2019 (deja vu...have heard this before the past years....)
We cannot call this an evolution or revamp of a previous concept as it's an 'all-new engine' design they started in 2018.
And involving almost all engine components.
"Given the ambition in terms of power improvement for next year, pretty much all of the engine will be new," added Abiteboul.
I hope they finally hit the right concept though, would love to see Hulk and Ric driving their pants of.
Being able to build a new design for all engine components, improved from lessons learned, could turn out really great (...or be a total dud). We will see when testing starts.
But realistically I'd see a season with a lot of hiccups again for Renault.
