Renault Power Unit Hardware & Software

[carisi2k]

Because I watched the Grand prix all weekend and it was clear to see that this is the case. Renault powered cars finished 4th, 11th and 12th and the only McHonda left finished 14th. Ricciardo was able to pass a Williams Mercedes twice with DRS which would not have been remotely possible 12 months ago (regardless of whether he had a softer tyre or not) and the Renault of Palmer held off the Torro Rosso's with the superior 2015 Ferrari engine for quite some time.

Renault have made progress, although not enough to catch up to Mercedes or Ferrari. they have certainly put enough performance into the PU to make it the third best unit.

I agree however with what you're saying. Renault is probably slightly ahead of Honda at the moment. Although the full extent of it has yet to be seen. Bahrain probably gives a more complete picture of relative performance.

These videos are from 6 months ago and not 12 months ago. At the Australian grand prix last year Kyvat was out with a car problem and Daniel was a lowly 6th 1 lap down. Although I can't find the video I recall that on the reverse the williams was already past the red bull half way down the straight with DRS.

3rd edit.
It wasn't the horsepower that got Daniel past Bottas either it was the brakes.

Can we stop chassis comparisons in the engine thread? Thanks!

I think after today it's clear the engine has improved. A RBR jumping a Williams on straight line on same tires and heavy fuel has been a non existant picture the last years. Renault definitely needs to improve quali mode, but for only 7 tokens they did a good job regarding the race pace of the engine. Good energy deployment, driveablity and finally reliable. Looking forward to the power upgrade.

I remember they had a lot of token left unused from last season,that's why they just used 7 token of new tokens available this year.

They only had 1 unused token from 2015. The other 11 went to the unraced turbo and the late season upgrade that didn't give any performance increase

What they did, was to prepare the engine for 2016. It is the d-spec engine that is currently being used. What they didn't use last year was the new turbo and the new inlets. The old turbo was not optimized for the d-spec engine and hence it developed less power. The high back pressure of the turbo was another main issue last year ...

Finally makes sense that Renault gave red bull half an upgrade last year, Saved them a lot of tokens this .
I wonder if Renault told Red bull this!

Well atleast it was reliable for most of the weekend. Not sure what the go was with Kyvat's engine but Daniels engine appeared to perform well and reliably.

Per Jon Wilde, Ted Kravitz reported on Sky during FP2 today that Renault's upgrade for Canada will focus on introducing HCCI.

I wonder how they overcome some of the issues that HCCI engines are supposed to have.I would have thought that working on laser ignition systems would provide greater upside then HCCI.

Not legal.

Don't all the other manufacturers already have HCCI (yes even Honda!) as from what I read, Merc introduced this in their Monza update last season. If this upgrade works and allows the Renault to catch up to the other manufacturers, I can see RBR sticking with Renault for 2017.

If it does produce the power Renault says it will produce then maybe also Torro Rosso for 2017. What is the bet that there might be an aston martin engine for 2018?

Even if it produces the power Renault says it will, Renault will still be quite a bit behind Mercedes and (probably) Ferrari. Renault is supposed to gain around 35hp, but the gap to Mercedes is bigger. Add to that that Mercedes might also bring updates to the engine by Montreal and Renault might be again some 30hp or more behind , however, at least the gap will be smaller than it is now.

From what I understand the Montreal update is supposed to bring 50hp. If it only bought 35hp then Red Bull would not be able to put up the challenge it thinks it can in the second half of the season.

[gandharva]

It is supposed to bring 35bhp which equals 0,5s per lap on average. These are official numbers from Renault and RBR.

If these numbers manifest in reality RBR will be able to jump Ferrari and Renault will (depending on car progress) be able to fight the midfield.

RBR won't jump Ferrari. They might get to where they can lock out the third row.

They already lock out third row in terms of race pace, even with broken frontwing.

Hcci is a mod only , bringing autocombustion 10% more ICe power during a limited time lap , renault is said to bring at least 35hp+hcci (10% mod for qualy) = around 50hp !

hope it work fine, the 20% illien input into engine r&d open lot of door to endeavor , plus Total R&d could be nice for rest of the season
