RE: Porsche LMP1 confirms 4-cyl hybrid
Discussion

Porsche has been working with 4 cyl turbo downsizing last years for the road cars, thats no secret. So it will probably be good marketing wise with the 4cyl in the racing cars 
Hope at least its not a dull soudning as a diesel, it shouldnt have to.
They were a little ahead of themselfs with the downsizing trend though...
1980 924 GT at Le Mans. Finished at an incredible 6th place, spending least time of all cars in the pits
They were a lot earlier to the rally scene with the 912... Hope at least its not a dull soudning as a diesel, it shouldnt have to.They were a little ahead of themselfs with the downsizing trend though...

No mention yet of fuel type. One of their earlier videos released on engine development had a shot of what appeared to be a rocker cover with 'TDFI' on it.
Could we see a mid-capacity 4 cylinder turbo diesel from Porsche? With the Hybrid supplementing the top end?
It could be Turbo Direct Fuel Injection. JLR has GTDI Gasoline Turbo Direct Injection. Mitsi/Hyundai GDI etc. So the D doesnt have to mean dieselNo mention yet of fuel type.

...or a flat-12: http://youtu.be/FkP5Svl16QgI'm sure Porsche have done their homework and the 918 seems to have performed pretty well, at least at the 'Ring. It's a shame that can;t run in another class - 918 v McLaren P1 v LaF(sorry can;t bring myself to write stupid name).
I really hope this LMP is competitive too, as this could be a great series to take over my dwindling interest in the F1 Mario-karts* and it would be great to see Webber mixing it at the front.
- someone else's description, but sums recent news up perfectly.

I wonder if this engine has come, at least in part, of the still-born F1 engine project, back when the regs said I4 rather than V6?
Either way, the current LMP1 regs are certainly spicing up the technical side. V6 TDI Hybrid, V8 Hybrid and now I4 hybrid. Excellent.
Wasn't the idea that the "FIA world engine" being valid for WEC, F1 and WRC amongst others? 1 engine architecture with different turbo / cams / valves could be used for a veriety of formulae, making it better for all?Either way, the current LMP1 regs are certainly spicing up the technical side. V6 TDI Hybrid, V8 Hybrid and now I4 hybrid. Excellent.
Anyways, although I'm slightly sad that the new pork won't sound like the Aston from 2011, I'm happy to see anything that can take the fight to the Audis. If Porsche are bringing the tech to the street as well - all the better. Although no doubt some posters will be frothing at the mouth at the horrible idea of an inline 4 in a Porsche, I'm excited by the prospet of what thir motorsport activities will being to the road cars.
Off the top of my head...
Sequential turbos
Varioram/ variocam
The Metzger engine
Clever 4wd
Probably the best brakes / ABS on the market for a huge amount of time (993 eta etc)
All of the above were spawned by Porsche's WRC / Le Mans work. If Porsche can make a potent, economical 4 then that's great by me - I'd love a 911 that did 50 MPG, it would really, really piss on the chips of HR when they try to take cars off the "acceptible private cars" list for my company car opt out scheme =)
I do wonder why people poo poo the idea of anything less than 3 litre v6. The best thing about Le Mans for me is the variety. You've got screaming 458s, raspy ( almost weedy ) 911s, thunderous corvettes ( the loudest but roughest by far), epic angry astons, the quiet but guttural audi which lets you hear how hard the tyres are working through the porsche curves 
, and the full on race eight toyotas. I missed the sound of saleens, jags and anything else that wasn't there last year.
People don't rate the quiet audis, but think about it... its an endurance race not a 20 lap sprint. Those corvettes must be losing the equivalent of a 20kw sound system ( 15 bhp )as noise being released from the explosions. The audi in comparison has something in the way that must be capturing the energy Turbo? Or just not releasing it as sound in the first place by looking at the design of the engine.
What will porsche bring? Maybe something quiet too. Whatever it will be something else in the mix to read up on and appreciate track side rather than winging about lack of sound. how about using your eyes and watching how fast it goes?
Whatever they bring dint think it will be under strict orders for position. It's a 24 hour race and a certain company called Toyota aren't also rans. I wouldn't be surprised if they take 1st overall this year. Both Porsche and Audi will be under orders to get a win!

The only decent-sounding LMP1 car of 2013 is the Rebellion-Lola. I don't know what the drivetrain is likely to sound like in the new Rebellion R-One but if it features turbocharging and / or hybrid power then it may not be particularly special.
I'm in two minds about whether this advancement is a good or a bad thing. As a motor racing enthusiast, I love progress, I love engineering development and I love the advancement of automotive technology through racing. The manufacturers are clearly stimulated by the challenge as well. The drama of watching a modern LMP1 racer is no longer delivered via its soundtrack. The Lola-Aston was the last truly mellifluous LMP1 car. Saying that, stand at the turn-in point to Maggotts and try to keep your jaw off the floor at the sheer, silent, violence of the cars' movements. It's a staggering spectacle in its own right.
I think, as fans, we have to accept that the sound of racing cars is changing. We won't hear another BMW V12 LMR, or a Matra MS670 or a Ferrari 312PB in the 21st century - those days are gone. If you want the old-school noise then it has to be at an old-school event. If you want cutting edge technology fought out by the best teams and fastest drivers in the world then WEC isn't a bad championship.
