I thought it might have been a littler simpler like the older system they had. For example the second generation R8 LMS might be RS5 or RC5, R for Rennsport, S for Sportscar or C for Coupe (as RS5 might upset Audi’s own marketing people) and 5 as it was the next number in order of projects.

German magazine SportAuto reports today Audi is going for some (radical) changes regarding the engine concept for the 2016 season. In addition to that Audi will trade the flywheel for battery technology in 2016.

The best bit of that if true is the effective confirmation that they are planning for 2016.

Will be interesting to see if "radical" means petrol...

If that's the case, Audi could also opt to be rather radical with their V6 TDI in 2015 for what would be the last year of diesel in endurance racing. No need to hold back as any future revision of the EoT will be irrelevant for 2016 onwards...

An I4 Bi-Turbo?
It will lower the weight, giving room for a larger MJ system.

VAG launced a new 2.0L I4 Bi-Turbo engine in the Passat, so there is a lot of road relevance in that choice.

Pleas please stick to diesel. I love the WOOOOOSH sound.

It does appeal in a futuristic kind of way...

Articus · 13 Dec 2014, 04:51 (Ref:3484594)

Well to be honest compared to most other P1's out there.... the Aston Martin V12 P1 is probably the only soundtrack worth burning petrol for...The other petrol P1's could go silent for all I care

But then wouldn't it be similar to Porsche's 919 ? 4 cylinders with battery technology? Also, what would VAG think about that?

If a small displacement turbo-charged petrol engine associated with a big hybrid system is the way to go to be competitive, then why should Audi refrain from following this evolution ? Even Toyota are likely to follow this path and ditch the V8.

What would VAG think if Audi were to stick with the "heavy" and performance-handicapped diesel technology ? Would that be good for the brand image ?

And while I am no believer in the Audi-in-F1 rumor, it would make sense for Audi to switch back to petrol, wouldn't it ?

TF110 · 13 Dec 2014, 09:34 (Ref:3484631)

Toyota said the opposite. They said if they would do a brand new engine, it'd be a 4L V8. Of note is the minimum weight of the 2L turbo engines in Super GT is 85kg. In the future class 1 (dtm and gt500) I think they agreed to the use of those engine rules.

Why would they do that? It won't save them any weight, and as we saw this year their V8 has better BSFC than the porsche's V4. It surly won't be because of reliability either. So this begs the question at least in racing conditions what's the point of downsizing.

carbon_titanium · 13 Dec 2014, 11:50 (Ref:3484654)

need to say that porsche started to project and develope the V4 engine since 2010... because of budget issues toyota just kept on using a DI updated and larger version of the TS030 motor. Toyota has already developed a competitive and fuel flow tuned turbo engine, the 2.0 L4 used in GT500 and successfully in super formula.

But what about that talk that one of the reasons for Audi and Porsche competing against each other is because they are using different technologies? I mean, if for some reason Audi and Porsche end up using basically the same thing, then in my point of view there would be no reason for both manufacturers being in the WEC at the same time.

The technical director and the head of the LMP1 project only joined Porsche in 2011, so this highly unlikely.

Thing is the rules clearly do not favor diesel. Worse, diesel is being handicapped performance-wise. In that respect, it make no sense for Audi to stick with diesel technology. Ultimately, what matters for VAG IMHO is to have both brands competiting at the highest possible performance level, even if this involves having two brands competiting with petrol engines.

thanks for the tip, ok let's say that the project and development of the V4 started in 2011, 3 years before the racing debut of the 919. It didn't change anything.

Spyderman · 13 Dec 2014, 13:42 (Ref:3484681)

More likely the start of 2012. Alex Hitzinger joined at the end of 2011.

Porsche is a V4, not an I4.
Porsche is a Petrol, where I suggest a Diesel (although I don't write it, I thought that the consensus was that Audi would do Diesel, unless otherwise stated)
Also the Hybrid technology is different between Audi and Porsche.

So a lot of things to differentiate Audi from Porsche, should they chose an I4.

But an intersting thought about the marketing value of Audi's Diesel engines:
I don't remember seeing Audi branding the TDI technology that much any longer. Or people talking about it, other than technical regulations discussions.

Perhaps Audi is freeing themselves up to choosing petrol?

Wrong on two things. Their budget wasnt the reason they chose a V8. On top of that it was a whole new engine compared to the Rebellion unit. And it does not have Direct Injection.

gustavobamba · 13 Dec 2014, 22:40 (Ref:3484785)

This in not "fully" related to Audi but instead is about diesel technology

"Renault is working on a two-cylinder two-stroke diesel"

"thermal efficiency of around 50 %"

LINK: http://www.motorpasion.com/renault/r...de-dos-tiempos

Can anyone explain what kind of engine is this?? Could this be considered for racing??? A lightweight diesel engine…isn´t this what Audi need to have a more powerful hybrid engine???

Feel free to comment, i don´t know nothing about engine´s

Sounds like a diesel powered Moped :b.
Didn't know that two stroke was able to be that efficient. Wasn't efficiency of the reasons there was a change to four stroke?
