LMP1 Non-Hybrids Slowed in EoT Change

LMP1 non-hybrids face power reduction, fuel capacity decrease for 6H Spa…

LMP1 non-hybrids have been slowed ahead of next weekend’s FIA World Endurance Championship season-opening Six Hours of Spa, following Equivalency of Technology adjustments made to the privateer entrants.

The FIA’s declared EoT for Spa, which was released last week, confirms both a power and fuel capacity reduction to the non-hybrids since last month’s Prologue pre-season test. 

It equates to roughly a 14 percent less available energy and a 6.9 kg decrease in fuel capacity per stint for non-hybrids compared to the configuration that was run at Paul Ricard.

The Toyota TS050 Hybrids, which per LMP1 rules retain the same performance levels as last year, has seen its 69 percent deficit to the non-hybrids in maximum fuel energy (MJ/lap) reduced to 49 percent for Spa.

That compares with the EoT for non-hybrids in post-Le Mans races last year, which had a 63 percent increase in fuel energy compared to the Toyotas and Porsche 919 Hybrids, which both ran in the 8 MJ Hybrid subclass.

LMP1 non-hybrids, which were permitted to run with 54 kg of fuel per stint at the Prologue, will now only be allowed 47.1 kg, with the Toyotas remaining at 35.1 kg.

The minimum weight of 833 kg for non-hybrids and 878 kg for the Toyota hybrids remain unchanged as well as the maximum fuel flow, although adjustments have been made to the size of the refueling rig restrictors for both types of technology.

The changes come in the wake of data collected by the FIA at the two-day test, which saw the pair of Toyota’s top the time sheets, but had been running outside of the EoT regulations.

It’s understood the No. 11 SMP Racing BR Engineering BR1 AER had set the quickest time at the Prologue out of the laps completed by cars in full conformity of the regulations.

With the FIA yet to release the EoT for Le Mans, it’s understood further adjustments can still be made in the run-up to the French endurance classic.

    This is going to get messy, all these privateers who thought they had a chance are seeing that go out the window. The ACO just can’t bring themselves to let Toyota have a chance of losing to them.

      Totally agree. If Toyota wins Lemans it will mean nothing because they had NO competition. SMH

      SMP and Rebellion where both quicker than Toyota.

      Spa, we’ll have to see.

        How do you figure? Did Toyota run any of the test conforming to regulations? Why is any team allowed to run an official session out of compliance? All the article said was that Toyota ran out of compliance, and that SMP ran the fastestlap of any car in compliance.

          Toyota’s fastest lap in compliance with EoT was 1:38.142.

          • Privateers

            April 25, 2018 at 10:31 pm

            You don’t think that they were sandbagging?

        • Blaneysellstrashbags@Ring24

          April 25, 2018 at 2:36 pm

          Yes they did run laps in compliance to regulations. They were slower than some of the privateers

      Ok thanks for the input but it’s flawed. An untested Rebellion Oreca set a 1:37 multiple times at the prologue with Lotterer behind the wheel. That wasn’t a qualifying type of run either. Toyota set at best 1:38’s in their long runs. So not only was that Rebellion faster but it was setting times better than the almost 2 year old Toyota. New teams being on pace is fine but in Rebellion’s case that was their first actual test. The scope for improvement is big considering that. Imagine the car being sorted out and having a better understanding of the way it handles. Plus the private teams are NOT locked in for certain aero kits (Toyota is), so there’s extra performance from that to be had. It’s no wonder they pulled them back a little.

        EoT is used to balance all LMP1 cars. Previously EoT was only used to balance hybrid cars.

        EoT does not look at laptimes, they look at actual performance data downloaded from the cars. Prior to Paul Ricard there was only data provided by the teams. Now they have 30hrs of real data from the test.

        The Toyota is the base level performance benchmark. The EoT is set so non-hybrids can be as quick over a lap and stint. Which they where at Paul Ricard

      As much as I wanted Toyota to win at Le Mans since they are in wec, the much I want them to lose this year.

    That is SO stupid. That’s below stupid. It’s stupid’s basement.

    This series dies outright if the ACO keeps treating privateers as an afterthought.

      as if some fans forget to use thought before their outrage. Look at the compliance-based laptimes from the test and tell me who the fastest 2 chassis were?

      Forget outright laptimes, i’m talking per regulations what we will see at Spa – those averaged laptimes were far different than what was displayed on the timing sheets over 1 lap.

    Good thing there’s no BoP in LMP1, though, right?

    • AudiTT

      April 25, 2018 at 11:48 am

      EoT balances the performance/efficiency potential of a power train. Despite the same EoT Toyota where off the pace in 2015, but on the pace in 16/17.

      BoP aims to balance laptimes by any means, power, weight, aero.

    The ACO needs to make sure that at least one Toyota is running at the finish so they can win every race and win Le Mans. The only way to do it is to BOP the privateers! Shame on the ACO! And now IMSA is again considering adapting their stupid rules in the future…shame! But the positive is that it leaves me more time to watch historic group C racing!

    • Andy Flinn

      April 25, 2018 at 8:55 pm

      Yeah, like 1982 when Porsche won the championship with GT points because the ACO was affraid to award their prestigious championship to a tiny French manufacturer (Rondeau).

    The ACO are desperate for Toyota to win. Once they have won then they will change the EoT to help the rest of the LMP1 Class.
    What happens however if the Alonso car wins? Will the headline read “Alonso wins Me Mans” or will Toyota get the credit?

    The privateers are already slower than the Toyota’s! Where is the logic?! I think the ACO are terrified that Toyota will win at Le-Mans and then just walk away! I know they’ve said they are committed to the WEC until the next rule set but that’s just words! Unless they have signed an actual contract that can be enforceable in a court, then expect Toyota (And Alonso) to win just about everything! I suppose it puts a bit more pressure on Toyota to be much more reliable than they were last year.

    • Henning Strenge

      April 26, 2018 at 1:30 am

      Yes, because when untested Cars are already.4 seconds faster then Porsche at Paul Ricard and over a second faster then Toyota,they are slower…🙈

      Yes Toyota could be sandbagging, but i’d wait until Spa to really comment on that topic. Let’s just try to enjoy the race.

    It just doesn’t sit well with me how arbitrary BoP/EoT always seems to be. Like how are these decisions actually made/weighed? If a team finds speed is the EoT or do they “deserve” the gains they made. I get that its part of what makes this possible but man do will i celebrate if/when they come up with something better that mitigates the need for it. It’s just a lazy solution if nothing else.

  10. BOP and EOT Sounds Bad to Me

    What will the FIA WEC announce next?
    – Stage Racing
    – Competition cautions
    – Fan boost for Toyota

    The fuel capacity makes sense, when you have less power you do get more fuel maileage.

    It is hard to take when teams that may have had a chance of victory being pegged back but the world wants ‘All Hybrid’ so they want that technology to succeed. Also, Toyota have spent millions competing against Porsche and Audi and have continued to support the WEC so I suppose the FIA WEC want to show it was worth Toyota continuing with the TS050. We have been spoilt over the years but Toyota have to beat Le Mans as much as the opposition. Pity Porsche and Toyota didn’t sell/lend their Hybrids to other teams.

    There’s one common problem here: Toyota. They had their chance to win fairly but failed, miserably. Get them the H-E-[double-hockey-sticks] outta here and let the true pay-to-play-er who worked to get where they are in LMP1 race.

    This is excellent news. I don’t want the WEC to become like NASCAR or those DP’s where they stifled innovation. All this does is make the non hybrids work harder and keep innovating. WEC is about new technology and innovation. If you can’t do it, then go race elsewhere.

    Having been a racing fan since the mid sixties I can state that this pick and choose the winner mentality doesn’t surprise me at all. You can build a car that will dominate their class for years and it will only achieve minor success throughout it’s career do to a governing(ment)body picking winners and losers. In economics this is Socialism/Fascism. Seeing how Europe is Socialist. This inevitable “solution” hasn’t been a surprise at all. A huge disappointment maybe but not a surprise. Why should anyone build something innovative if it’s just going to be penalized for it. Why should anyone work hard if everyone is going to be treated and paid the same. This SJW/PC equality cancer has infested motorsports and is the main reason I have lost a lot of interest in it.

      But you have taken the time to comment on a motorsports site so you must be interested lol.

      There is a difference between picking winners, and creating a level playing field via EOT or BOP to prevent the team with the most money winning (aka F1). I will reserve judgement until the first race is done but it looks like they are trying to make the field equal on pace (so there is good racing) but give toyota one lap extra per stint on fuel which would be grossly unfair in my eyes.

      The ACO are stuck between a rock and a hard place with regards to Toyota. If they win Le mans they will say job done and leave. If they loose, the embarrassment of losing to a bunch of privateers will be too much to stomach and they will still leave.

      I for one don’t know what the obsession is with having big manufactures in LMP1. They won’t attract Casual fans as they will never watch long endurance races, only real Sportscar racing fans will appreciate it. I would much rather see actual prototype manufactures like radical,liger,ginetta,riley,norma,juno,Osella,Tata,wolf,dallara,oreca etc. duke it out over 24hrs with capped budgets.

      The ACO lost its way by trying to compete with F1 in my view.

        The governing bodies rely on OEMs for funding, after commercial sponsorship has drought out because the tobacco/alcohol money went away.

      Plantfeeder, if you’ve been following this type of racing since the mid-‘6Os you should remember the Porsche 917 being essentially banned from Le Mans after the win in 1971. That essentially paved the way for a French three-peat (Matra) from 1972-1974.

      The 917 then went on to dominate the Can-Am and put that series out of business.

    It seems to me that Toyota ran unrestricted to make the privateers show their pace at the Prologue. Then when Toyota ran to the rules, amazingly they were slower (perhaps on purpose). FIA then slows the privateers a week before the first race under EOT. The privateers weren’t smart enough to resist the bait at Prologue.

    Privateers didn’t have any chances at a LM win even before, but this completely kills them. Any aero package they were working on must now go into the trashcan.

  21. Davide

    It seems that all the people who are commenting are motorsport engeneering…On which basis you can tell that the restrictions are too much for Privateer???

    Fact 1: the EoT is always existed in the WEC in order to have on the same level different technologies. Eg. Diesel, Petrol, N/A, turbos, hybrid, etc.
    The alternative is to fix the rules like in LMP2 or DPi and have less variety and technological interest. All with same engines.

    Fact 2: the EoT isn’t based on lap times. The EoT is based on drivetrain performance. It’s not a BoP system which mitigate the lap times of every car

    Fact 3: the EoT isn’t based on a single team. Again, the EoT is on the technology. The benchark is the best for each technology. If 3 teams runs turbo engine, the benchmark will be the best turbo.
    If 2 teams runs N/A engine, the benchmark will be the best of the two.

    Consideration 1: the simple lap times of 2018 Prologue aren’t indicative of the performance. Instead of read pure numbers, if you do a little analysis on the real pace, Toyota was in 4th or 5th position.

    Consideration 2: but again, this doesn’t matter, EoT isn’t based on lap times.

    Consideration 3: Toyota will be the favourite for the budget and the team. Not for the EoT.

      How dare you bring common sense and rational thought to sportscar and EoT debate? Don’t you know this is only an area for couch experts and knee jerk reactions that their works is ending because of 1 rule change?

    How do we actually know this is a reduction in performance for the non-hybrid cars? How do we know how much fuel they were actually using? This does not limit the performance of the car, just the number of pit stops required, so yes it will affect the race result but it will not slow down the non-hybrid cars.

    The main objective of the ACO here is to make sure the hybrid car does more laps per stint than non-hybrid. It’s a political thing, nothing to do with performance
