Further into the future, the ACO also teased a hydrogen fuel cell category from 2024 onward, athough at present there are very few details of how this will work or how it would be integrated into the FIA WEC and Le Mans 24 Hours. ACO technical director Vincent Beaumesnil simply said that those details were “coming soon.”
-------------------------

Coming soon?
Maybe IMSA will wait until the race is over and decide what to do to make the Hydrogen car the winner.

Default Toyotas excluded from Silverstone results...was four laps ahead

Toyotas excluded from Silverstone results; Rebellion inherits win

By: RACER Staff | 23 hours ago Toyota Gazoo Racing’s pair of TS050 HYBRIDs that dominated the 6 Hours of Silverstone have both been excluded from the results after failing post-race scrutineering. Fernando Alonso, Sebastien Buemi and Kazuki Nakajima had won comfortably, with the sister No. 7 second, both cars four laps ahead of the nearest privateer runner.The move elevates Rebellion Racing’s Gustavo Menezes, Thomas Laurent and Mathias Beche to the win, followed by the sister No. 1 Rebellion of Neel Jani and Andre Lotterer, with SMP Racing’s Stephane Sarrazin and Egor Orudzhev third.That marks Rebellion Racing’s first overall race win in WEC competition and the first privateer overall victory in championship history. And because of the decision, Menezes becomes the first American driver to win a WEC race.It’s also the first non-hybrid win since 2012, the first season of the FIA WEC, when the first two races at Sebring and Spa Francorchamps were both won by non-hybrid powered Audis.

A stewards statement indicated that the race-winning No. 8 “deflected 6mm on the right hand side and 8mm on the left hand side under the specified 200 N load at the front of the skid block.”For the No. 7 car, “The front part of the skid block deflected 9mm under the specified 2500 N load on both sides of the skid block.”RACER understands that Toyota will appeal.In addition to both Toyotas being excluded from the result, the No. 91 Porsche 911 RSR driven by Austria’s Richard Lietz and Gianmaria Bruni was stripped of its second-place finish in GTE Pro for failing the minimum ground clearance measurement test, promoting the No. 67 Ford GT of Andy Priaulx and Harry Tincknell to second and the No. 92 Porsche of Michael Christensen and Kevin Estre to third.“Unfortunately we were informed after the race that an irregularity was detected in the ride height, said Pascal Zurlinden, Porsche director of GT Factory Motorsport. “That threw our number 91 car out of the classification and advanced the number 92 car to third place. We’re still leading the manufacturers’ and drivers’ classifications. Now we need to focus on the next tasks.”

Default IMSA confirms final BoP adjustments for Petit Le Mans

IMSA confirms final BoP adjustments for Petit Le Mans

Image by Michael Levitt/LAT
357 sharessharetweetemail
By: Marshall Pruett | 11 hours ago The final Balance of Performance adjustments for the 2018 WeatherTech SportsCar Championship season have been awarded to Acura in Prototype, Porsche in GT Le Mans, and Acura again in GT Daytona along with Audi.IMSA’s 10-hour Petit Le Mans finale at Road Atlanta will see the pair of Acura Team Penske entries work with more turbocharger boost at the upper end of the rev range. The 3.5-liter twin-turbo V6s built by Honda Performance Development will help the ORECA-built ARX-05 DPis to achieve slightly higher top speeds thanks to the extra power available from 6200 to the 7650rpm redline. IMSA has also given the Acuras extra fuel (+2L, now 75L total) to compensate for the rise in horsepower.Mazda’s RT24-P DPis received a modest fuel increase (+1L, now 81L total), and all of the spec WEC LMP2s were given an identical fuel capacity change (+3L, now 75L for all).

More IMSA!

In GTLM, Porsche’s 911 RSR model will carry a sizeable amount of ballast (+15kg, now 1265kg) that brings the Porsche GT Team entries to the same minimum weight as the Ferrari 488 GTEs and Ford GTs. The 4.0-liter flat-six-powered Porsches will deliver more power to its drivers through bigger air restrictor openings (+0.7mm, now 32.2mm total) and will have more fuel (+1L, now 97L total) to consume.BMW was the only other recipient of BoP changes in GTLM. The BMW Team RLL-led M8 GTEs have forfeited a significant amount of fuel capacity for Petit Le Mans (-6L, now 86L total) coming off a win last month at WeatherTech Raceway Laguna Seca.In GTD, Acura’s title-contending NSX GT3 chassis will fight for championship honors while laden with more ballast (+10kg, now 1330kg total). The final BoP adjustment for Road Atlanta goes to Audi’s R8 LMS GT3, which surrenders power via smaller air restrictor openings (-1.0mm, now 39.0mm total) and fuel through less fuel capacity (-2L, now 94L total).Practice for Petit Le Mans begins on Thursday.

Default Roar Before The 24 BoP tables released

Roar Before The 24 BoP tables released

Image by Galstad/LAT
1.0k sharesharetweetemail
By: Marshall Pruett | December 21, 2018 2:02 PM IMSA has released its Balance of Performance tables for the upcoming Roar Before The 24 test that will be used as a first step to shape its final BoP figures for the season-opening Rolex 24 At Daytona.DPi
With the new separation of DPi and LMP2 models into individual classes, some of the BoP work completed by IMSA centers on creating distinct performance levels for the two categories.
Image by Levitt/LAT
Weight reductions across all four DPi brands have been made. Using the most recent race at Petit Le Mans as a reference for where the cars have been taken, Acura’s ARX-05 is down 10kg from 940 to 930, Cadillac’s DPi-V.R drops 20kg from 950 to 930, Mazda’s RT24-P is the same 905kg, and Nissan’s Onroak DPi loses 5kg from 940 to 935.On the power front, Acura’s twin-turbo V6 engine will have a slight bump in boost from 5600rpms to its 7050rpm redline. Cadillac’s naturally-aspirated V8 will breathe more freely with an increase of 0.3mm to its dual air restrictors, bringing the total through-flow number to 31.9mm. A 100rpm hike in maximum RPM from 7500 to 7600 has also been made.Mazda, with its small four-cylinder turbo powerplant, has seen its boost figures adjusted along with new RPM reference points that differ from Petit Le Mans. The most notable aspect of the adjustment comes in an increase from an 8600rpm redline in October to 9300rpms to start 2019. Boost figures, in general terms, have been nudged up or down by small margins to accommodate the 700rpm hike in revs.

More IMSA!

The Super Long Holiday Travel Companion Podcast

The Week In Sports Cars, Dec. 22

Nearly identical to Acura’s boost increases, Nissan’s twin-turbo V6 has gained power from 5800rpms to its 7100rpm redline.Maximum fuel capacity adjustments were also implemented ranging from losing two liters to gaining three liters for the four models, with those changes based on power increases or anticipated fuel economy, in order to equalize the lengths of a full-tank stint. A minimum refueling time of 30 seconds will be enforced.
Image by Dole/LAT
LMP2
Only the French Ligier JS P217 and ORECA 07 LMP2 models are expected for the Roar and Rolex 24, with ORECA holding the monopoly of entries through its customer. Despite the unlikely appearances of Dallara’s P217 and the Riley/Multimatic Mk. 30 LMP2s, IMSA has set a uniform minimum weight of 940kg for all cars, cut the maximum RPMs from Gibson’s spec V8 engine from 8750 to 8250, set the maximum fuel capacity at 70L, and refueling must take at least 34 seconds.

Part 2
Image by Galstad/LAT
GT Le Mans
Using the same Petit Le Mans reference points, BMW’s 1220kg minimum weight for its M8 GTE and Corvette’s 1240kg for its C7.R are unchanged. Two models will gain weight as Ferrari’s 488 GTE goes from 1265kg to 1270, and the biggest leap lands with Ford’s GT, up 20kgs from 1265 to 1285. Porsche’s 911 RSR is the sole GTLM car to carve weight, cutting 25kgs from 1265 to 1240.Corvette has lost some power with a decrease in airflow to its naturally-aspirated V8 as its Petit air restrictor total of 31.5mm has been narrowed to 30.6mm. The other naturally-aspirated engine, Porsche’s flat-6, is unchanged at 32.2mm.Of the three turbocharged models, BMW’s twin-turbo V8 has gained boost from 5000rpms to its 7000rpm redline, Ferrari’s twin-turbo V8 has not been altered, and Ford’s twin-turbo V6 has lost boost from 5500 to its 7200rpm limit. Similar to DPi, fuel capacity changes are relatively small, and each stop has a minimum time of 34 seconds.
Image by LePage/LAT
GT Daytona
Finally, with the same October benchmark in place, starting minimum weights for 2019 fluctuate a bit. Acura’s NSX GT3 is down 10kg from 1330 to 1320. Audi’s R8 LMS GT3 has grown by 20kgs from 1320 to 1340. BMW’s M6 GT3 hasn’t changed, but Ferrari’s 488 GT3 has gotten lighter with a 20kg decrease from 1345 to 1325. Lamborghini’s Huracan GT3 is up five kilos from 1300 to 1305, the Lexus RCF GT3 has gone in the opposite direction with 20kgs coming off to make its former 1380 a slimmer 1360. The Mercedes-AMG GT3 is downsizing by 15kgs from 1390 to 1375, and Porsche’s 911 GT3 R holds station at 1285kgs.Power modifications start with Acura’s twin-turbo V6, which loses small amounts of mid-range boost to its 7500rpm peak. Of the two other forced-induction GTD cars, BMW’s twin-turbo V8 has not been touched with boost alterations, but Ferrari’s twin-turbo V8 is down some boost from 5500 to its 7500rpm redline.Of the non-turbos, airflow has been improved for the Audis with a move from 39mm openings to 40. Lamborghini has lost 1mm in a decrease from 39 to 38, and Lexus has gained 1mm from 39 to 40. No changes have been levied for the 36.0mm assigned to Mercedes-AMG or Porsche and its 43mm restrictors. As well, no changes to maximum RPMS for any of the GTD models have been outlined for the Roar.In line with the other classes, small fuel capacity changes have been implemented and a minimum pit stop time of 40 seconds will be used.

Default INSIGHT: Why are there only 42 confirmed Le Mans entries?

INSIGHT: Why are there only 42 confirmed Le Mans entries?

Image by Hartwell/LAT

649 sharessharetweetemail
By: Stephen Kilbey | February 12, 2019 4:52 PM Yesterday’s 42-car provisional entry list for the 2019 Le Mans 24 Hours oddly leaves more questions than answers. With no explanation, the first tranche announcement was shortened by eight cars from the planned 50. And,

remarkably, race organizers have thus far not confirmed any members of the IMSA GTLM pack that have joined the FIA WEC GTE Pro teams to varying degrees over the past three years, or, in the case of the factory Corvette team, the past 19 years!This means that a number of

teams from IMSA, as well as from the European Le Mans Series and Asian Le Mans Series paddocks hoping to gain entry to the French endurance classic, will have to wait until March 1st when the final entries are due to be confirmed to see if they made the cut. That’s a full month less than usual for the teams concerned to plan their campaigns at Le Sarthe.More Le Mans/WEC!

Major update to 2020 'Hypercar' regulations announced

Di Resta completes United WEC and Le Mans line-up

The Week in Sports Cars, March 1

But why was this? Why 42? With no public-facing explanation from the organizers, speculation is the inevitable result. And once you delve into the numbers game, and the bout of musical chairs going on behind the scenes ahead of the second phase of the entry reveal next month,

there’s plenty to consider.Yesterday’s announcement included eight automatic entries and the 34 ever-present FIA WEC entries – all of which were known prior – with no major surprises outside of the TRSM Ginetta G60-LT-P1s being an omission. RACER understood that Ginetta filed

entries for both (now AER-powered) cars after gaining control of the entry from its original customers, but has (thus far at least) been refused a slot on the grid. It’s a surprise, considering the ACO’s pressing need to keep LMP1 alive and well through to the start of the new regulation

cycle in 2020/21.So, in what is now an increasingly unpredictable process, who is still in play for an entry, and which direction will the ACO go with the tough decisions that lie ahead?
(Photo by LAT Images)

As it stands the entire IMSA GTLM contingent has been made to wait, and it begs the question: Is it those entries causing the issue here? With four automatic invites still to be handed out from the conclusion of the Asian Le Mans Series season later this month, three of which

look set to be won by ELMS regulars, is the ACO just waiting it out, seeing who they don’t need to cater for in the remaining 18 slots?That way the ACO can make a choice. Does it bring in additional factory cars from IMSA (RACER understands that both Porsche and Ford are

hoping for two extra cars apiece and that Risi has put in an entry) and gain the additional punch and marketability that a class stacked full of factory entries brings, or be loyal to customers in Europe and Asia?With just 18 slots left, and 33 cars in with a shout (as the ACO revealed

that 75 cars total were applied for), there will be lots of disappointed parties next month. And, to be fair, there were plenty of stakeholders left disappointed and confused yesterday also. Corvette Racing for instance, the race’s longest-serving current team, set for a big 20th

anniversary year and its last with the C7.Rs, wasn’t part of yesterday’s batch. Now one would assume by looking back in the history books that Corvette will, of course, receive two entries. If that’s the case though, why didn’t the ACO just hand the entries out?
(Photo by LePage/LAT)

So just how many of the IMSA entries will get a place? If things take an unexpected turn at Sepang in the Asian Le Mans finale, will the ACO cut the IMSA factories to just one apiece? Will Risi get in? At present they have not ticked the box of making a full-season commitment

anywhere, a proviso for a Le Mans entry in normal circumstances.It would be easy to discount the importance of privateer cars and assume that the ACO wouldn’t ever turn down factory entries, but that, in the long run, maybe wouldn’t be such a smart move. With uncertain times

over the horizon (particularly at the top of the tree with the 2020 Hypercar regulations), and privateers constantly proving to be the ever-present backbone to ACO sports car racing, turning them away isn’t easy.Almost the entire European Le Mans Series LMP2 and GTE fields are in

the running for an entry, aside from automatic invitees RLR, JMW, Proton and G-Drive Racing — with the LMP2 teams in particular eyeing the numbers game with no little interest. They’ll be encouraged by one other factor: the ACO’s recent attempts to balance the entry at Le Mans 50/50 — or rather 30/30 — between their combined LMP grid and combined GTE grid.
(Photo by JEP / LAT Images)

Look at loyal teams like United Autosports (which fields 11 cars across three series plus a limited IMSA program and a 2019/20 WEC entry planned), and Algarve Pro (also fielding multiple cars in Europe and Asia), that are yet to have entries guaranteed through merit (though the

Asian Le Mans finale will come into play) and could, depending on the ACO’s preference, end up with no cars on the list at all.Then you have to factor in teams that don’t enter multiple cars in multiple series, but have performed well recently such as French LMP2 teams Panis

Barthez Competition and IDEC Sport, and that’s without mentioning teams like High Class Racing and Cetilar Racing that are investing heavily into ACO championships – the former buying new cars for 2019, and the latter opting to step up from the ELMS to the WEC in

2019/20.Add into the mix other wild-card entries, such as the potential for an all-female LMP2 entry from Michael Shank Racing (albeit serviced by an existing ELMS team) and it only gets tougher to decide who to put on the reserve list.It’s therefore more understandable for the

ACO to decide to wait it out until March to reveal which of the remaining applicants won’t be making the list. The nature of the last-minute decision to change the new two-phase format with no explanation, though, is strange and for those most closely involved, rather jarring.It

leaves more questions than answers, and at this point all we do know, beyond the 42 cars that we already figured would be at Le Mans, is that Part 2’s reveal will provide the answers to some very pressing questions.
