LMP2 Subject to BoP Adjustments

FIA able to make BoP adjustments for LMP2 cars in World Endurance Championship…

Balance of Performance adjustments will be permitted in the LMP2 class next season in the FIA World Endurance Championship.

The new-for-2017 cars, featuring spec Gibson engines, ran without any BoP adjustments this year in the WEC, European Le Mans Series and IMSA WeatherTech SportsCar Championship, although one-time ‘joker’ updates were granted to three of the four constructors for next year, in an effort to equalize the cars.

Now, it has been revealed, in the publishing of the 2018/19 WEC sporting regulations, that further adjustments can be made to each car’s weight, fuel capacity and aerodynamics throughout the WEC season, at the FIA Endurance Committee’s discretion.

Per the regulations, up to 30kg of weight could be added, along with as much as a 10-liter fuel capacity reduction and newly allowed “aerodynamic restrictions” for 2018.

It’s understood the committee would take measures to reduce the performance of the fastest car, rather than speed up the slower prototypes.

“Should a particular model of car perform too well, under the terms applicable to the adjustment of performance the Endurance Committee may take immediate measures to reduce its performance,” the regulations state.

It’s unclear if any BoP adjustments would also be applicable for the ELMS and WeatherTech Championship, although the 24 Hours of Le Mans falls under WEC rules.

BoP adjustments had been part of the previous-generation LMP2 regulations, which allowed multiple engine manufacturers and constructors.

    So basically close to the entire field will be slowed for the couple non oreca entries. Could be good for lmp1 speed differential, sad to see the lmp2 loose time. Hopefully those joker updates knocked some time off last year’s models

    I doubt there’ll be enough LMP2 entries next year for this to be a concern.

    Hmm…trying to adopt DPi formula in a few years…starting to use American style bop and pit stop format…the French are renowned for their ability to surrender they should do so now and admit IMSA has a more sustainable formula going for them. Embrace it

    So why on earth did they bother with allowing joker updates to even the field when they were going to do BOP anyway? Surely it would have been easier and cheaper to just to do BOP from the outset.

      Serisouly. What was the point in all the joker debate and approval process if everything gets balanced? It’s pretty damn close apart from Le Mans, which might all change with the updates from Dallara and Ligier. I hope IMSA parts further away from the ACO and doesn’t follow this trend. The 2nd part of the IMSA season was really well balanced in my opinion.

    It’s not April 1st, what’s going on?

    Good. Not entirely sure why they didn’t use BOP for LMP2 last season anyway.

    As far as I can see there will again be no other full-season LMP2 entry than Oreca 07. So this BoP will be only for Le Mans, and then on which basis? Only from the times set on the Le Mans test weekend? This test will then become a sandbagging event. This makes no sense.

    I’m certain this is primarily aimed to keep an LMP2 off podium at LeMans. People have been curious how LMP1-L and LMP2 would mix given the 50 or so horsepower gap. I think this is the answer. Load everyone in LMP2 up with lead and an air restrictor!

    Good thing Dallara, Ligier, and Multimatic just spent all that money on carbon fibre, wind tunnels, and CFD!

      While the horse power may be 50-100 more than than LMP2. The LMP1 class will also have a lot more downforce and all gold/platinum driver lineups while the LMP2 still have to a silver/bronze in one of the 3 spots.

      Personally, the LMP2 should be pegged down a bit. They were a full 11 seconds faster in 2017 compared to 2016 at Lemans. But they were only able to do a fuel stint of about 35-40 minutes.

    This could gave been prompted by Oreca itself to cover its bases in case Dallara or Ligier’s updates has given them faster performance. Dallara has some serious resources. They just had not produced a sportscar chassis since the R8, about 15 years ago. So Oreca i’m sure Oreca is mindful.

    Hopefully the Riley is up to part with the other 3.

    This looks a lot like the ACO is trying to protect LMP1. They nearly got embarrassed last year by DC, and they don’t want the stress again this year. I, for one, would love to see just one 100% BOP-free race each year. Open it to all WEC and IWSC full season participants, and run it on a course that neither series runs regularly – maybe the full ‘Ring, or the “roval” at Charlotte. It would be great to see if the Caddies could keep pace with the Toyotas, or if the Vettes and Fords could hang with the Gibson powered LMP2s, or if anyone could touch the unrestricted 488s in GT3.

      You want to see a 100% BOP-free race?

      YouTube Mark Donahue, CanAm. You’ll see what a BOP-free race will look like, a race to see who comes in 2nd, 5 laps behind Mark in only a 2 hr race.

      Modern days prototypes on the Ring? You need to cut yourself off the spiked egg nog.

        Can-Am was not only BOP-free, it was practically rule-free. If you were to run just one BOP race a year as I described – with cars that were full season entries in their respective series – the Donahue sort of dominance wouldn’t occur. But we would get to see just what some of these cars (especially the GTs) are really capable of.

      You really think the Caddies could keep pace with the Toyota’s lol they aren’t even faster than the WEC LMP2 cars.

      • Trevor

        Even when saddled with BOP in the early races last season, the Caddies were far faster than the other LMP2 based cars in the field, and the BOP only got more severe. We all know the Caddies were sandbagging from the very first timed runs in December. That motor’s a monster. I wouldn’t be surprised if they could just dial it up to hybrid levels of horsepower.

    Makes absolutely sense. Come up with more advanced and faster LMP2, then allow for updates, then come with BoP and weight penalties.
