Any info on how they ran those 22 laps? If those were made in concessive order, so in good stints, then they still did a good job. I've readed somewhere from GA that heat builds up to its peak around the 5th lap. If they ran 5-7 laps in a stint without any failure then that's a good sign.

aren't they also required to run on some kind "show tire" for photo events?
not sure which tires lotus ran at jerez, during jerez testing i recall most cars had no lettering on the walls,
lotus did run with letters so not entirely sure.
from the sporting regulation:

Each competitor will also be permitted to carry out two Promotional Events (PE)... A PE shall be defined as an event in which a competitor participates purely for marketing or promotional purposes. No such test may exceed 100km in length and only tyres manufactured specifically for this purpose by the appointed supplier may be used.

I doubt the promo spec tyres would hinder their ability to lean on the engine & make no mistake, that is exactly what they would have been focusing on given the troubles at the first test.

Good news. No one wants to see half the grid hobbled with a faulty power unit.

Let's hope they can get some decent mileage at Bahrain.

Im a bit confused is Renault Problems aren't cleared at all to the level they wanted or is some thing with Lotus Car design?

it's hard not to wonder if this isn't all planed out behind closed doors.

Honestly, I hope if this happens the other teams raise holly hell. I mean can a team or manufacture sue the FIA, because they feel they are colluding with a competitor?

The teams probably wouldn't raise hell, but surely the forums would. I think I'd rather Renault get their engines sorted prior to the cutoff than endure the inevitable FIA/Todt/French Engine Manufacturer accusations and arguments here and elsewhere.

Plus, they're putting themselves in a bit of a Catch 22. I mean, they've been going on the past week about how much progress they've made, trying to save face, but then they're going to ask for special dispensation? One or the other, guys. That's why I suggested in anther thread that I would doubt if any of the other teams would complain about Lotus' test-that-wasn't-a-test. They'd probably rather Renault make a bit of progress now, so they can make an argument against dispensation later.

Minardi fuels the rumors...
"According to circulating information, the situation seems more difficult than that and not easy to solve," the 66-year-old wrote in a posting in Italian on his website.

"It seems that Red Bull are exploring a possible change of engine for 2015," added Minardi.

He said he has also heard that Renault, struggling to solve the obvious problems with its turbo V6 'power unit', has gone beyond the walls of its Viry factory and is now "shopping" around for technical fixes.

"That has practically never happened before as, quite rightly, Renault has always sought to preserve its technology," said Minardi.

"This news can only feed suspicions of structural problems in the engine that are not easy to solve in the short term.

"Obviously, I hope to be proved wrong as soon as the testing in Bahrain, but undoubtedly we are living through a chaotic time in Formula One," he added.

Renault did confirm that the STR filming day didn't go well...
"We hoped not to have any problems, but we had a few further ones," said Taffin. "But in fairness, it was not a surprise. We knew what we had in the car and we thought we would get away with it based on what we did in the first filming day [with Lotus], but obviously not.

But overall, they think they're 3 weeks behind, assuming the first Bahrain test goes as planned.

I've wondered much the same thing myself. Always a conspiracy brewing somewhere it seems.
With regard to that Autosport article, I found it interesting toward the end where Taffin makes the assertion that is only a few specific problems they need to get resolved and then they will be 90% there... It's those last 10% that probably comprise the major design flaws that have been rumored. Back to conspiracy theories, who really thinks Renault would have intentionally included an inherent design flaw in their engine for the later benefit of be able to exploit the regulations and claim engine design improvements under the guise of improving "reliability"?

It depends on what you want to believe or it may be the last time Renault apocalypse can be milked. We'll see soon enough in Bahrain, writing won't change reality.

Plenty of info and quoting it fully doesn't makes sense, two small ones: 1. (from the other article) - "Having said that, we are not saying we have massive issues on reliability because we have done some good tests on the dynos and we know that each part is working fine, we have to make it work together." That (and ERS as a source of problems) would be another report contrary to "crankshafts" theory.

2. (About Toro Rosso test) "The reasons are well-known on our side and we have since worked on it but there is nothing we can do on a filming day."When you start the day off with a configuration, you have to run all through the day so it's difficult to react."

Might explain two different days with Lotus.

I didn't mean it that way, I was thinking more along the lines of doing a crappy job, initially for one reason or other and then catching up later.

But that has a very high risk: FIA might tell you "no" or the other teams make more points and those missing points kill the chances of a championship-

Read the autosport article carfully. The title of that article is misleading and Taffin's words must be contextualized. I bet he just answered this question ''will Renault ask for a rieliability break'' and he said why not, if we have reliability problems. and he means every manufacturer will ask for a little break, like they did for a V8. He says Renault solved the Jerez problem, but no one knows if they will discover other problems later...

It makes no sense to me to believe that there is an issue that will need 20 weeks to sort out. The Engine itself is a fairly well known quantity and I simply do not believe that any mechanical components are giving those problems. As you would expect Red Bull went a step too far in disregarding the advise from the power train engineers in terms of cooling and packaguing requirements. At least that is what I make out of this.

Newey always pushes things to the limit and this time he has pushed Renault too far. The other customers are likely to get what Renault and Red Bull have concocted together and subsequently they share the present misery. I have been predicting this possibility for some months. IMHO it will cost Red Bull the first test and parts of the next to redesign the package and start the catch up game with Merc and Ferrari. By the time of the third race they could be on a level playing field and they will know exactly what is possible and what is not. The other teams will have less information of how you push the thermal envelope. These problems are not unsurmountable. It is necessary for Adrian IMHO to listen to his engine supplier a bit harder and allow for greater margins for once. But I expect that to happen from now on.
Funny that Adrian confirmed today what I thought back in January. lol

I'm anxious to see the expression on the face of Renault clients later this week in Bahrain. This by itself usually speaks more than words... or any official press releases for that matter.

Will it be smiles of long faces? I guess we'll know soon enough :D
