A Modest Proposal: Endurance Class Structure

There are a number of competing factors that are in conflict regarding the classes in endurance racing. Entertainment may limit innovation, cost controls are not exciting, BoP is always contoversial, waivers piss everyone off. I don't pretend that my ideas are the answer, but here they are.

In order to maintain a high diversity of cars and a sufficiently large number of teams competing in the class, it required that the car makers produce a road car that would be competitive within the rules. The perceived need to keep the racing close for "entertainment" purposes brings pressure to adjust the performance of this diverse set of cars to some magic lap time that all can achieve, or failing that to use other gimmicks that "equalize" the performance over a race distance, like modifying fuel capacity or fuel flow that would affect pit stop strategy. At least the organizers haven't stooped to "push-to-pass" or DRS.

Another factor that affects the class is allowing cars that would not normally fall within the regulations to compete through the granting of a waiver. The Ford GT did not meet the homologation requirement of producing the minimum number of road cars prior to entering competition, so they were granted a waiver. The Viper was granted a waiver in GTLM in the IMSA series even though the displacement of the engine exceeded the maximum displacement in the regulations by 2.5L. There are many other examples of this practice.

Car makers want to win races to advertise their cars as "better" than their competitors. "Win on Sunday sell on Monday". This aspect places great pressure on the organizers to "level the playing field" to allow any of the cars to win. To a similar extent teams also want the chance to win to attract sponsorship and drivers as well as satisfy their competitive drive. If someone actually made a better car, shouldn't they be allowed to race it without being hobbled? In his racing autobiography Mark Donohue stressed that what his team (Penske) always strove for was the "Unfair Advantage", in fact that is what the bio was entitled. I submit that all teams strive for such an advantage and that impulse advances the sport.

One of the current concerns is that the newest entrants to the class: Ford GT, Ferrari 488, and BMW M6 are dominating the class over the older entrants and the pressure to conform has resulted in charges of "sandbagging" and the issuance of BoP adjustments between races and even between qualifying and the race. These moves are controversial to say the least. Some are concerned that the "gaps" between the classes will be eroded if these new cars aren't slowed down. Could there be a better answer?

Maybe. I think the entire class structure might benefit from a re-evaluation. The following are just my thoughts on one way that might help solve this puzzle of what to do with the endurance classes. There are probably many others that could answer as well.

I would like to see a prototype class that meets some definition of "road legal" but otherwise ignores minimum production numbers. This "GT Prototype" class would contain the halo cars not only for cars like the Ford GT, but would allow early entry for the mid-engined Corvette and the next Aston Martin that are currently on the drawing board and headed for competition in the near future. Such a class would keep the high cost of these puppies away from the real modified production models that typify GTE/GTLM and still allow the factory teams a place to play. This should be a real prototype class: eventually the cars in this class would show up in some form as a production model. This would be different from the current definition of "prototype" in LMP1 and LMP2 which will never be produced in road-going form. At some point this "GTP" class might supplant LMP2.

The successor to the current GTE/GTLM class would be for real road cars produced in numbers and the racing parts that make them competitive would be required to show up as parts available through dealerships. This approach was used in the original Trans-Am regulations (1966 - 1973), and parts that were developed for racing had to be made available to the public (even if "for off road use only"). This should make for easier entry into the class for new teams. Cost caps on the performance parts might need to be imposed in such a scheme. Regulations would be strictly enforced and changes/adjustments would happen only between seasons. Cars must conform to their homologation forms, which is where any needed "balancing" would take place; allowed modifications would be spelled out similar to the way the SCCA handles their varied classes.

There is currently a divergence in the "lower" GT classes between IMSA and ACO/FIA: the IMSA GTD class is basically GT3 with Pro/Am driving teams, which relies entirely on BoP while the ACO/FIA runs GTE-Am which basically runs the same cars as GTE-Pro but with Pro/Am driver lineups (as well as eliminating the newest spec cars). Both of these approaches have their pros and cons and either could accomplish the goal of bringing in more car and driver diversity. I favor the GTE-Am approach, but there is something to be said for cars that have a place in more than one series.

The five current Prototype classes need a re-think in my opinion. LMP1/H is now stricly a WEC beast. They are for factory works teams only and it is practically mandated to be the overall winning class. Why is there this fiction that the LMP1-privateer class is part of LMP1? They should be classified separately from LMP1/H. LMP2 evolved from LMP675; a lightweight that could compete against their heavier and more powerful LMP1 (evolved from LMP900) cousins; until the LMP2s started winning some important races overall, then suddenly it was thought neccessary to cost cap the class and make them heavier than the LMP1 cars. Now the ACO/FIA are requiring a spec engine and only four chassis options as well as Pro/Am driver teams. LMP3 has a similarly restrictive formula, intended to replace the aging spec LMPC cars.

In my proposed scheme I would like to see a lightweight prototype that would be allowed to compete for overall wins, but against the cubic euros spent in LMP1/H that is very unlikely to ever happen. Barring that, LMP2 should still be less restrictive: allow more chassis and engine suppliers and impose a cost cap if needed. Requiring production-based engines would make the class more relevant to road cars, but if race engines prove more cost effective over the course of a season, then perhaps that restriction could be dropped. If LMP2 can't compete for overall wins, then there are only two purposes for them: a less expensive way to go prototype racing, and allowing non-professional drivers a place to go prototype racing. Keeping it Pro/Am (like the ACO/FIA) is probably justified.

In IMSA the proposed DPI serves a different purpose that LMP2 in the ACO/FIA; it will be the top class, expected to take overall wins, so they should be able to run all-Pro drivers. They should also be able to use any tire they want. I would drop the requirement to run only one of four chassis and restricting bodywork to single chassis/engine combinations. This bodywork restriction is aping the old Daytona Prototype model which came about belatedly in the Grand-Am series and has resulted in only one manufacturer bodykit. Allowing bespoke bodywork should be an option, but not a requirement and any engine should be usable in any chassis. A more generous cost cap might be in order. My feeling is that DPI, modified along the lines proposed here, could form the basis for a replacement for LMP1-privateer. If that happened then there could be a place for DPI at Le Mans without upsetting the Pro/Am LMP2 teams.

If there is any place for a spec formula in endurance racing, then it would be in the replacement for the LMPC class. Currently the thinking is that this would be LMP3, which isn't quite spec. I have mixed feelings about this class. A fully spec chassis/engine/tire class would make for a better driver training prototype entry platform, while normally a spec car is anathema to me personally. As it is currently, it is neither fish nor fowl. LMPC worked quite well for a long time, so maybe the full-spec formula would work well as a replacment too. At least there would be a ready market for used cars in this class, making entry even more affordable.

In summary my imaginary class structure would look like this (names could be changed, but these refer to existing classes where applicable):

LMP1 - Leave it as is and let the ACO/FIA do with it what it will. This is a WEC-only class.

LMP1-privateer/DPI - loosen the DPI regulations and converge these two classes into one, classified separately from LMP1

LMP2 - Pro/Am prototype run by privateers only with cost caps. Could become Pro/Am versions of DPI (maybe)

LMP3 - Full spec Pro/Am prototype. Training ground and low-cost prototype entry platform.

GTP - Road legal prototype halo cars. Works teams with Pro drivers. The playground for dream cars.

GTE-Pro - True modified production cars with strict regs and "factory" parts. Pro drivers.

GTE-Am - GTE cars with Pro/Am drivers. Alternatively GT3 cars would form this class

If you think that 7 classes are too many, recall that the 1966 Le Mans 24 had 9 classes. It is only in more recent times that it was thought that 4 was the most we should have. The only place all 7 would run is in the WEC. There would probably be a natural selection process that would eliminate unneeded classes. Each series would choose which classes they support.

The goal of such a re-organization is to reflect reality, eliminate the BoP controversies as much as possible, stimulate fan interest, and try to keep everyone happy. Getting the organizing bodies, the manufacturers, the teams, and the fans to agree on something so radical is probably not possible. These are my thoughts, at present they are only valuable to me.

Is BOP Needed in GTE?

This past weekend was the 84th running of the 24 Hours of Le Mans and Ford's victory in the GTE Pro class came about partly as a commemoration of their first victory 50 years ago. This entire season there have been accusations that Ford was "sandbagging" to avoid Balance of Performance (BOP) adjustments that would lessen their chances of winning. In 1966 BOP didn't exist at Le Mans, but strict adherence to the rules and the more primitive technology of the era kept things fairly competitive. BOP came about to attract otherwise non-competitive cars so that manufacturers could run their products in the big races like Le Mans, either by allowing modifications outside the rules, or by burdening the faster cars to "level the playing field".

If that weren't enough, otherwise ineligible cars were granted waivers to allow them to compete, relying on BOP to cover any gross advantages thus created. Two recent examples come to mind: the BMW Z4 V8 and the Viper. At the time the BMW was running in IMSA you couldn't buy a Z4 with a V8 at your BMW dealer, but IMSA wanted BMW so in they came. The Viper's 8+ Liter engine displacement vastly exceeded the GTE/GTLM class limit of 5.5L. Chevrolet, when they moved from GT1 to GT2 (which became GTE/GTLM) reduced their displacement from 7L to 5.5L, but Viper relied on waivers and BOP to put them in the game. I'm not saying that these were bad decisions, but the waiver that allowed Ford to run their new GT before there was a road car was in the same spirit, with the major difference that otherwise the Ford GT is within the technical specs for GTE/GTLM. The impulse was the same: attract another manufacturer into the series. I would have been happier if Ford had started their new GT program a year earlier so that the road car would have been out and the waiver would not have been needed, but I don't think the new rules were out back then. The fact that the competing manufacturers agreed to the waiver makes it a bit more palatable; they realized that adding the Ford brand would bring more attention to the series.

In an ideal world neither waivers nor BOP would be needed. The only cars allowed to compete would be those that fit within the rules, and the rules would be strictly enforced. If a car can dominate within those rules, then it shouldn't be penalized for it, the next year's rules might need adjusting but for at least one year, such a car should reap the rewards for being the better car. Having said that I would hate to see the costs of winning at Le Mans be driven to the stratosphere by companies building road-going prototypes that would require a syndicate to buy. Think of America's Cup yachts. I never have and never will be able to even contemplate buying any of today's road model GTs, but there is a large difference between even a Ferrari and a Veyron.

In 1969 there was a car that debuted at Le Mans that adhered closely to the rules and dominated qualifying and was allowed to compete without waivers or BOP adjustments. This was the Porsche 917, but it wasn't a prototype; Porsche managed to build 25 of them to satisfy the homologation requirements to run in the GT class (S-5000). The air-cooled flat 12-cylinder engine exceeded the new prototype displacement limit of 3.0L. So this pure prototype car competed against the aging, heavy, road-derived 5.0L GT40-MkI and Porsche's official prototype the 908. By the end of the race the 917s had retired and it was left to the 908 and the GT40 to slug it out. The old GT40 prevailed finally, the same chassis that won in 1968. The 917 went on to win the following year as fictionalized in Steve McQueen's "Le Mans". Unlike this year's GTE pole-sitter, in 1969 there was no insistence that there be a BOP adjustment between qualifying and the race.

In my youth I was a committed Ford fan. I was excited when it became known that Ford would enter the 2016 Le Mans 24 and field full-season entries in both the WEC and IMSA series. I knew it was no coincidence that it was the 50th anniversary of their 1966 victory and I rooted for them to win, but I didn't expect that they could in their first attempt. I am happy that I was wrong, but I was disappointed by the last-minute protest of the #82 for leader light failure. I think that was a mickey-mouse move considering that other cars had been allowed to run for hours with the same failure, such a call within the last 20 min. of the race is unforgivable. As a PR move that was as just bad. I am glad that Risi ignored the call, and that the offsetting penalties resulted in no change to the finishing order of the race. Ferrari deserved their podium finish. This is an echo of another bad PR move on Ford's part from that 1966 event; in order to stage a formation finish, team orders went out to the lead #1 GT40-MkII of Ken Miles to slow down to allow the #2 of Bruce McLaren (same lap in 2nd) to catch up and cross the line with the #5 of Ronnie Bucknum (12 laps down in 3rd). In the event the ACO ruled that since the #2 started further back, it had covered the greater distance and was awarded the win. This robbed Ken Miles of the win. Already in 1966 Ken had won the Daytona 24 and Sebring; a win at Le Mans would have been an historic achievement, but this failed PR move robbed him (and Ford) of that legacy. Ken died in testing later that year. The fact that this is remembered 50 years afterward should be a cautionary tale for Ford and anyone else that puts PR above sportsmanship and competition.

Ford's Return to Le Mans


The development of the new 2016 Ford GT competing in the company's return to Le Mans has been seen as a commemoration of their sweep of the overall podium 50 years ago. Back in 1966 with the GT40 Mark II (and 1967 with a GT40 Mark IV), Ford won overall as entrants in the prototype class (P+5.0, Group 6), but their new car is running in the GT class this year (GTLM in IMSA and GTE-Pro in FIA/ACO). This being so, it should be recognized that the Ford GT40 Mark I managed the overall win at Le Mans in 1968 and 1969 as a GT (S5.0, Group 4) competitor. The new car has more in common with the Group 4 GT40 Mark I of 1968-69 than the prototype GT40 Mark II/IV of 1966-67. The Mark I and the new 2016 GT are derived from road cars, unlike the Mark II and Mark IV of yesteryear.

As my own commemoration of these events I thought I would post a little geneology of the Ford GT40.

In the Beginning


In 1963 in the wake of the company's decision to compete in endurance sports-car racing and the failed effort to acquire Ferrari, Ford partnered with Eric Broadley's Lola Cars to develop their own Le Mans competitor. Based initally on the Lola Mark 6 (powered by Ford 289 cu. in. V8), the first GT40s ran at Le Mans in 1964. These first cars DNFed but showed great potential and set the fastest lap of the race (driven by Phil Hill). In that first Le Mans for Ford, the team was run by Ford Advanced Vehicles (FAV) managed by John Wyer. The next 3 years (1965-67), the team was managed by Carroll Shelby while the construction of the basic GT40 continued to be built by FAV under John Wyer. Much of the evolution of the of the GT40 into what became the Mark II took place at Ford's Kar Kraft facility in Dearborn Michigan and at Shelby American in Venice California. FAV was  responsible for the GT40 Mark I road-car production as well as supplying cars to Shelby American.

The Coming of the Big Block. 


The 1964 GT40s that ran at Le Mans were initially powered by the 1963 Ford Indianapolis engine, an all-aluminum pushrod 255 cu. in. (4.2L) V8 of 375 bhp, developed from the road-car "Fairlane" iron V8 engine introduced in 1962. The transaxle was the same 4-speed Collotti unit used in the Lola Mark 6. The gearbox was not up to the task and was eventually replaced with a 5-speed ZF unit. The Indy engine was replaced by the iron 289 cu. in. (4.7L) Ford V8 as used in the Shelby Cobra. The Cobra V8 in the road-car was tuned to deliver 306 bhp equipped with a single 4-bbl carburetor; in Le Mans trim and with 4 Weber carbs it produced 375 bhp. The front-running GT40s were still using the Collotti gearbox and didn't finish the race.

In 1965 the main Ford effort focused on the GT40 Mark II. The 4.7L small-block V8 was replaced by the 427 cu. in. (7.0L) Ford "side-oiler" V8 of approximately 500 bhp as used in NASCAR and drag racing. In order to handle the torque of this beast, the gearbox was replaced with a 4-speed prototype Ford Unit utilizing the gearset from the full-size Ford Galaxie. In addition there were some aerodynamic, brake and cooling improvements.

The 1965 Le Mans was pretty much a repeat of 1964: the cars were fast but not reliable, they DNF'ed. In the current era it's pretty much accepted that a 3-year development cycle is what it takes to produce a winner (or determine that it will never be a winner). The year 1966 was the year of Ford's third attempt at Le Mans and the car was a winner, fast and reliable, and the reason for Ford's 50th anniversary commemoration this year.

But the story of the GT40 doesn't end in 1966. 


In 1967 Ford developed the GT40 Mark IV (the Mark III was a road car variant). Unlike previous GT40s, this was all-new, designed and built by Kar Kraft and developed and run by Shelby American. It built on the lessons learned on the previous models and shared the powertrain from the Mark II. The winning car was driven by Americans Dan Gurney and A.J. Foyt. There had been some snark about the 1966 car being built in Europe and driven by New Zealanders Bruce McLaren and Chris Amon; 1967 was an "All-American" victory. The ACO changed the rules for prototypes for 1968: maximum engine displacement would be 3.0L. This made the prototypes from Ford and Ferrari obsolete after Jan. 1st 1968. Ford withdrew from Le Mans competition.

On January 1, 1967, FAV was dissolved and it's assets in England were sold (at a 90% discount) to John Wyer Automotive Engineering LLC (JWAE), which continued to hold the contract to build the GT40 road cars as well as service customers and handle spares. The rules for competing in the GT class (Group 4) required that there be at least 50 cars produced and they would be limited to a maximum displacement of 5.0L. Those rules suited JWAE very well. The GT40 Mark I was no longer a prototype, but a GT car. JWAE teamed with Gulf Oil and Firestone Tire to form the Gulf-Wyer team and compete in endurance racing beginning with their GT40-derived "Mirage" in 1967.

For 1968 Gulf-Wyer entered 3 GT40 Mark I cars in Group 4. They ran the 302 cu.in. (5.0L) Ford V8s with the addition of the aluminum Gurney-Weslake cylinder heads producing 449 bhp. and utilizing the ZF 5-speed gearbox. Drivers Pedro Rodriguez and Lucian Bianchi won overall for Gulf-Wyer, defeating all the new prototypes.

For 1969 Gulf-Wyer entered 2 GT40 Mark I cars after their own new prototype 3.0L Cosworth DFV-powered Gulf-Mirage prototype proved too unreliable to compete in the 24 hour race. This time winning drivers Jacky Ickx and Jackie Oliver pulled out the overall win after the brand-new Porsche 917 GT (Group 4) cars dropped out, leaving only the older (and less powerful) 908 to finish a close second. Two interesting notes: the winning car was the same as the 1968 winner, chassis 1075. The rules for 1969 lowered the number of cars produced in order to qualify for Group 4 to 25 cars; Porsche took advantage of those rules to produce 25 pure prototype 917s equipped (initially) with 4.5L flat-12 racing engines and run them as GTs. In 1970 and 1971 the factory Porsche 917s were run by Gulf-Wyer.

In 2005 Ford produced a new "Ford GT" road car to commemorate the 100th anniversary of the founding of the Ford Motor Company. The design of this new car was influenced by the earlier GT40, but was strictly a road car, Ford did not form a works team nor did they produce racing versions. In 2011 the privateer Robertson Racing team placed third in the GTE-Am class at Le Mans; husband and wife David and Andrea Robertson celebrated their wedding anniversary on the Le Mans podium, carried there by their Ford GT.

The "Ford Era" at Le Mans of the late '60s produced some other interesting milestones. In 1967 Dan Gurney sprayed Champagne on his colleagues and spectators from the podium, beginning a tradition now seen on nearly all motorsport podia. In 1969 Jacky Ickx protested the "Le Mans start" by walking across the track at the start of the race, meaning he started dead last yet still won the race (his good friend Willy Mairesse was badly injured in 1968 by not securely fastening his seatbelts in a crash at the start of the race); in 1970 that starting practice was abandoned. Often overlooked, in 1965 the World Championship of Makes was won by the Shelby American Cobra "Daytona Coupe" GTs, the first American marque to do so (Dan Gurney and Bob Bonduant drove theirs to 4th overall at Le Mans in 1965). The iconic "Gulf livery" of light blue and marigold (ICI P030-8013 and P030-3393) was first seen on the JWAE GT40-based "Mirage" of 1967.

The appearance of the Ford GT40 at Daytona in 1965 is my personal milestone. That appearance marked my first awareness of endurance sportscar racing. I was a 14 year old "Ford fan" in 1965, and the fact that the GT40 was so damn attractive (and a Ford) got me hooked when my friend Steve made me aware of it (that year I built a "slot-car" with a GT40 body). Prior to that I followed home-town racer Parnelli Jones' exploits at the Indy 500 (he won in 1963 and nearly did in 1967), but this sports-car thing was new to me. After 1965 I followed Can-Am and Trans-Am road racing (as well as a teenager could back then) until I finished college. I am looking forward to Ford's debut of their new GT this year. I have to keep in mind that this is only the first year of their program, I shouldn't expect too much right away, but I can pull for them anyway.
