GP Commission: FP3 Reinstated, GPS Banned in MotoGP, Traction Control Allowed In Moto3

There's good news and bad news for the opponents of electronics in motorcycle racing from today's meeting of the Grand Prix Commission, held in Madrid in Spain. MotoGP's rule-making body met to discuss changes to the regulations for the 2011 and 2012 seasons, and electronics was one of the subjects under discussion.

But the first order of business was to rearrange practice. The changes made in the cost-cutting frenzy between the 2008 and 2009 seasons have finally been scrapped once again, and the four-practice schedule used by MotoGP for so many years before makes a welcome return. The schedule had been partially reinstated at the end of the 2010 season, with four sessions of 45 minutes replacing the three one-hour sessions which had been used for the past two seasons. Though the reception was overwhelmingly positive, the one complaint that riders had being that the 45 minute sessions left little time to make changes during the session. 

That problem has now been solved, as the GP Commission has agreed to return to four one-hour sessions for the MotoGP class from 2011. The Moto2 class will see four sessions of 45 minutes on each race weekend, while the 125cc class will have two sessions of 45 minutes on Friday and Saturday morning, and two sessions of half an hour in the afternoons.

Though the MotoGP class gets more time on the track, there are still good reasons to suspect that they will not spend that time actually circulating. The six engine allocation limit remains in place for the MotoGP class, meaning that teams and riders will have to be careful about putting too much mileage on their limited supply of engines. What the extra time will allow the teams to do is to try more radical setup changes during practice, as pit crews will have more time to work on the bike both during and between sessions.

Two more minor changes were also announced, allowing generators on the grid to power tire warmers for all three classes, and switching all three classes to the MotoGP format of three riders on each row of the starting grid. The three-rider grid rows had been under discussion for some time, with safety being the main reason being put forward by the idea's proponents. They argued that the chaos that unfolded in the first turn of so many Moto2 races could be avoided if the riders were further apart at the start.

Though this is undoubtedly true, there are two arguments against making such a change. The first is the most obvious: With 40 riders on the Moto2 grid, the gap between the riders at the rear and at the front is huge, with 117 meters between the front row and the 13th row, where the 37th, 38th and 39th fastest qualifiers will start. Those extra 117 meters mean that the riders in the rear row will reach the first corner with a much higher terminal velocity than the riders on the front row, and such a speed differential throughout the grid could also cause chaos, and perhaps even more serious crashes.

The second objection is less serious, but more practical: At a track like Aragon, for example, which has a rise leading on to the start and finish straight, the riders on the rear of the grid will simply be unable to see the starting lights, as the lights at the front of the grid are hidden behind the crest of the hill. That is a problem that is relatively easily solved, but it can only be solved by the circuits spending money, and times are tough for circuits too.

But the most interesting part of the rule changes comes in the two sections concerning electronics: one single sentence about the MotoGP class, and several long paragraphs about the new Moto3 class, due to replace the two-stroke 125cc class from 2012.

To MotoGP first. At first glance, it appears that the Grand Prix Commission has finally done what so many fans have been clamouring for for so long: from 2011, GPS appears to have been banned. But the exact wording of the new rules is that the only GPS allowed to be fitted to the bikes is the unit provided by Dorna. 

This is a long way from banning the GPS-based traction control that the fans had wanted. After all, the teams are merely banned from fitting their own GPS units, they are not banned from using the signals provided by the Dorna unit. There is every reason to suspect that the Dorna unit will be less accurate than the specialist items used in the top-spec electronics systems fitted to the MotoGP machines, but they will most likely be good enough to be useful.

But the really bad news is that the fans grossly overestimate the effect that using GPS has on MotoGP electronics. GPS is a quick and easy way of determining the position of the bike on the track, but it can be fairly simply replaced by using the engine and wheel speed data to calculate the bike's position accurately enough for the really useful data - camber and track slope - to be taken into account in the bike's traction control systems. The banning of GPS will have a barely noticeable effect on how the machines behave.

GPS has very little bearing on the amount of sliding and wheelying that the fans say they miss so much. The on-board accelerometers and gyroscopes have a much greater effect, the accelerometers being used to control wheelies and slides, and gyroscopes monitoring the bike's attitude, and passing that information back to the traction control system, which can then use it to manage wheel spin.

The one method that may prove an effective means of limiting electronics is the imposition of a standard ECU, the 'brains' of the machine. And this is exactly what has been imposed on the Moto3 class. The new class, which will see 250cc four-stroke singles replacing the current 125cc two-stroke singles racing in the 125 class, will have a standardized ECU supplied to all competitors.

Hopes that a spec ECU will be used to reign in the influence of electronics systems in Moto3 are in vain, however. The list of abilities that the ECU must provide include traction control, launch control, and controlling back-torque using variable engine idle. The specs issued by the Grand Prix Commission for the standard ECU basically allow a fully-fledged traction control system, and the list of requirements is not far off those of the current MotoGP machines. Teams willing to spend a lot of money on electronics strategies may yet be able to gain an advantage over less well-funded teams. But given the other limits set on the Moto3 class - a rev limit, a maximum price, and an 81mm maximum bore, the electronics could be the only way of gaining an advantage.

A spec ECU is not the only thing that will be standardized in the Moto3 class. Tenders are being requested for tires, oil and fuel supplies, as is the case in Moto2.

GPS

The GPS rule is interesting but the sense I get is that the factories have moved away from the concept instead using faster processing to calculate what is actually happening to the bike rather than looking at models to try to predict what should be happening to it. I would guess that if the factories felt the technology was still relevant, GPS wouldn't have been banned without a lot of public pressure and commentary from Ezpeleta.

From a fan's perspective, I think the ban is a good thing but not because the technology was affecting the racing, rather that is is (was) antithetical to what most fans believe racing should be. Even moreso even than traction control, GPS represented a removal of rider control in a manner that has no relationship to what many of us enjoy about motorcycles themselves.

Mere crums...

Poor, very poor. There is still enough electronics to control who (only factory teams) can win a race.

Sad.

You cant get a little pregnant.

As expected, putting the Genie back in the bottle is proving to be difficult indeed. While many of us would like a return to the heady days before "real" electronics, they are gone forever.

I would also speculate that this will not be the last technical bulletin to come from the FIM regarding rules and regs, and we may yet see a spec ECU- obviously not for 2011, but perhaps for 2012.

It is probably helpful to keep in mind that even national level superbikes in AMA are now running Marvel 4 electronics packages, which are quite sophisticated. As a result, it simply wouldnt do to have a superbike with a "better" electronics package than the HRC GP bikes. Just sayin...

It's not the electronics that kill the racing

Its the fuel limitations. To save enough fuel to keep acceleration maximized when the bike is nearly vertical both turn entry and exit need all this electrickery to make the engine run very lean to save fuel. On turn entry the engines need to be run very lean and so need sophisticated controls to make the it run smoothly during downshifts and on turn exit the bikes can't afford the wasted fuel of wheelspin so they can't turn with the rear tire anymore. No wheelspin removes a big tool for riders and effectively restricts the racing line to a narrow window.

2012 could be very interesting, for the first few races at least. Destroking a gsxr or s1000rr to around 900cc may make it able to run at full power for the entire race with 24l so would not need such thorough electronic control. Ducati is making a 930 because they know a 1000 will be tough to restrict to 21l and still make the finish line. Maybe a 900-930cc production based engine can afford to have much less sophisticated fuel strategies yet still make it with 24l. A smart CRT with a good rider and those 3 extra liters could possibly pull upsets, at least until that CRT is re-categorized due to performance. Then they are screwed.

Generator tyre warmers

Was the problematic cold front tyre at the start of the race not a huge issue for all the Ducati riders season past ? Is this the 80 second fix Burgess was keeping up his sleeve ? HA HA.
Nevertheless, I reckon this allowance is a very good move by the FIM.
I can see nothing but good come from that ruling.

FP3 = Rossi & Honda charity

4 sessions at 1 hour a piece. What could be better for Rossi and Honda. Rossi needs saddle time to rebuild the bike ASAP. Honda have the best reliability so they get more track time to work on setup.

It's the last year of unlimited 800cc 21L competition. Honda vs. Valentino seems like a nice script for Dorna to revisit.

Postscript

Enjoyed that phoenix1.Honda vs Rossi revisited.Back in 2004..Rossi, and you know the rest...2011 may well prove to be 'payback'.
Blank cheque book for the Yamaha assault back then.Looks like a brand new blank cheque book year at Ducati/Rossi for 2011.
HRC are in the pounds seats,I believe. 4 works riders to Ducati's 1. No,I'm not dissing Nicky,but within the big picture,Ducati have chucked everything at the Rossi venture.HRC have wisely not put all their eggs in one basket.
Back to topic,4 sessions.Good to see that.
Yamaha,confidently waiting in the wings.
Postsript 2011 may well read....'How fast you go depends on how much money you bring to the party'.
Alternatively....'If you can't fix the kit,fix the rules'.
Maybe even as far as....'The bike is where its at,not the rider'.
Prove otherwise by racing against us on a two wheel anything within the ambit of the FIM MotoGP rules.

HRC

I am not really disagreeing with your point but I think it is important to note that HRC has tried this approach before and it failed miserably. When they don't have a clear lead rider - who is getting results - HRC has historically failed to find a direction.

That said, I believe that Honda is starting from a position of strength with a strong bike and two riders who are clearly able to be fast on it so they are not in as much of a need to find a direction.

traction control

Traction control on 50 hp singles. Really?

RdP reckons...

So they may ditch GPS position sensing and go back to the age old sea faring positon fixing method of dead reckoning. That could be really intersting for Randy, i'd hate to think where his ecu will think he is after 10 laps or so, his "unique" lines and frequent off track excursions mean he probably completes a few hundred meteres more than the rest, itwill confuse the ecu reckoning that he's two corners ahead of where he should be

Thoughts on new rules

"But given the other limits set on the Moto3 class - a rev limit, a maximum price, and an 81mm maximum bore, the electronics could be the only way of gaining an advantage."

Great, as if electrickery hasnt done enough damage to our sport already it looks like ruining the Moto3 class before it even gets off the ground. Like DrDan wrote, why do we need TC etc. on 50hp 250cc bikes. Is this more to with the fuel delivery once more.

Regarding Moto2, hows about reducing the field to 32 bikes. Quality not quantity right. Either by limiting entries, or by adjusting the 'qualifying percentage' so it makes it harder for all 40 bikes to make the grid. 107% is pretty generous by Moto2 standards.

I'd hope to see a control ECU on the table for discussion for 2012. I think it would be a good thing if Dorna, IRTA, FIM can come to some agreement about which electricks to allow and which to limit. It would reduce costs, it would further equality of teams, in theory at least. And it may allow for some more of the wild rider action we are lamenting. If fuel is really the issue however, is there any way to make a difference to electrics without increasing fuel capacity? Would restricting revs aid fuel limitations? Are the revs restricted in any way currently?
