No. Think Audi R15. Basically all the regulation put in place to hamstring that design approach have now been eliminated. Figure the Peugeot bee is out of the ACO's ear.

I welcome this approach as it might alter the current design trend with "f1 style" raised noses.

Oh, good. I thought the R 15 solution was rather elegant. I wasn't really expecting 956 type stick on wings to start appearing but you never know!

The 2014 regs are literally more of the same for prototypes, I thought the ACO and FIA would try and mix it up a bit with some variation after the DW had such a strong outing at Le Mans

There's a shot on Mulsanne's Corner in the Bentley Section that shows the rear of the Bentley's front diffuser and brake duct intakes, and it featured a 25mm thick trailing edge on the rear of the brake duct (which formed an extension of the front diffuser) to avoid that illegal "non-wing" wing deal.
It does seems that the ACO and FIA have favored either the Audi R15 solution, or want teams like Audi and Toyota for example to ditch the special front and rear clip deals for LM vs sprint race bodywork, or want things to be like the R8 and R10/908 days where dive planes, wing angle, and gurney flaps were used to tune the car's areo between LM and the sprint race circuits. |

Nothing to say you couldn't run the Bentley solution (aka the Peugeot solution, the Toyota TS030 solution...). The cars will not be fundamentally different to what we've seen currently or the past.

"And while we're at the front of the car, Art 3.5.4 alters the front splitter geometry in a couple of ways. First, the outer sections of the front splitter are no longer allowed to sit on the reference plane (Z zero), instead they must be at least 10 mm above Z zero. This will reduce front downforce slightly. But much more significantly, the provisions that previously mandated thick front “wing” trailing edges (3% of max element thickness or no less than 10 mm thick), which had been a response to Audi's original 2009 R15, are gone. This now allows true wings, that is wings with non-symmetrical cross sections and, more importantly, thin trailing edges, to be utilized." |

High noses might very well go away: "Art 16.2.2 increases the front foot well volume height from 300 mm to 350 mm. I'm told the reasoning is to allow more space for hybrid systems without compromising drive safety. Though this change comes with a built in aero penalty and compromise as the additional 50 mm height will encroach either upon the front diffuser area or project upwards raising upper surface of the footbox into the airstream. Naturally it depends relative to Z zero where the additional 50 mm height is located as to its aero impact." |

Forgive my ignorance, but the Z zero reference plane that you speak of, is that the middle of the front diffuser at it's current height, or is it the outside edges of the diffuser/front floor that sit lower? _/-----\_

Mike, does the draft have (considerably) different fuel flow limits compared to the LM lap fuel allocations in the presentation from June?
edit: "And while engines will all be equated through fuel flow meters (Art 6.2.1, of which all specifics are yet to be defined)" The draft doesn't actually have them yet? |

Z zero is the bottom of the car, the reference plane.

"And while engines will all be equated through fuel flow meters (Art 6.2.1, of which all specifics are yet to be defined)..." Cut and Paste from Draft V04: Fuel Flow Metering 6.2.1 ………. FIA will specify a fuel flow metering system so called "FIA Fuel Flow Meter". The system will have to be integrated into the fuel system according to the FIA specification included in Appendix D. Its location on the car will be managed in a receptacle of volume with minimum dimensions 150mm (width) x 200mm (length) x130mm (depth). It will be fitted on opposite side compared to fuel tank filler. Other specifications remain to be defined. |

I guess the final details are still being bargained then...

Mike, do you know how much drag the Big Honkin' Holes and the Big Honkin' Fin adds to the car?

However, I thought the original draft of the regulations specified an "adjustable front element". If the nose or suspension fairings form a fixed aero profile and the front of the foot well reaches the splitter then there is nothing to adjust and no space to fit a wing section! I presumed the introduction of adjustable front wings would preclude the need for delicate trim tabs/dive planes and other easily broken stick on bits. |

Under the table the FIA/ACO provides the assumped energy content and density of the two fuel type. Using those numbers, you can see that the energy allocations in both tables are identical:

RCE reported that the target efficiency in the 2014 rules is 220 g/kWh for petrol engines and 195 g/kWh for diesel engines (see post #2438). These numbers are confirmed in Appendix B of draft 4 on mulsannescorner.com

However, in 2014 they will have to produce that power with less fuel. So if engine manufacturers can not reach the efficiency targets, which are very ambitious, then the cars will have a bit less power. |

I think that the PDF was added later.
I was also surprised about the French text. I though that the whole rule book would writen in French and translated afterwards to (bad) English. Maybe the process changed a bit now that the FIA is got involved. |

I thought something like that too. This "The French version is the only one valid regarding the implementation and interpretation of the regulations" is still there though.
