The Tour de France kicks off, or should that be rides off, today. One of my most favorite events and this year should be as interesting as ever. It is not only a long race for the riders but also for us viewers with three weeks straight of TV coverage for several hours a day. Good job I'm not working full time!

Some predictable pole positions today with Stoner capturing the MotoGP at Mugello, Marquez the Moto2, and yes it is still raining on and off. Rossi continues to struggle down in 12th. Puts Stoner's performance on the Ducati in some perspective doesn't it?

It did rain in Imola yesterday, the results from FP2 were slow in being posted. Peugeot are on pole by a slim margin from the Audi, with Peugeot and the McNish Audi locking out the top four places. The Oak racing Pescarolo-Judd are 3 seconds off pole, but only 1.5 behind McNish, so at least they may catch a glimpse of them. The BMW's were quickest in the GTE class with three Ferraris hard on their heels.

Vergne took pole in Hungary for the FR3.5 and went on to win the first race, while Kevin Magnussen took his first British F3 pole, two in fact, following nicely in Dad's footsteps.

So, off to watch the Tour.

No not the vegetable drink but the Australian Supercar Series that is now going to Austin in 2013, having raced in the Middle East the last few years, although no one came to watch. I was told when Austin was first announced that ISC, i.e. NASCAR, were not likely to give them any races, so no NASCAR, Grand Am or AMA Motorcycles. So what were they going to run at this expensive facility to justify it other than F1, which is unlikely to make money for anyone but Bernie? The answer is to bring in other overseas series such as the V8Supercars. I bet Tony Cochrane is laughing all the way to the bank. Can you imagine what it costs to air freight these cars? They weigh at least twice what an F1 car does and cannot be broken down to a nice size to put in a plane. Volume is as big an issue as weight for planes. So this cannot be cheap for Tavo and the boys, they had better hope they pull a better crowd than the Yas Marina Circuit does.

I also heard a suggestion that the new World Endurance Championship US round might go to Austin rather than Sebring or Road Atlanta. Another great series, and one that can pull a crowd as we have seen at Road Atlanta. Sebring pulls a crowd even when the race has been cancelled, spring break and all. But again an expensive deal to put together, so a hard way to make a dollar, but I guess if you've spent the money you may as well use the place.

Martin Whitmarsh says he thinks that the US should have two F1 races, just like the old days, one on the east coast and one on the west. Not sure where that leaves Texas. Martin said he "had nothing against Texas and hopes they have a successful race,  but the natural hinterland for us is us the east coast and the west coast," which does not sound very supportive, so good luck Tavo.

It must be a very wet summer in Europe as it seems just about every MotoGP has problems with wet tracks. In Mugello hardly anyone went out in the second session due to the rain. In the morning dry session Simoncelli did his usual by now fastest lap, very closely followed by Stoner. Rossi broke down and is way down the field of only 16 bikes.

Imola seems to have missed the rain and the ILMC teams had dry conditions, Peugeot and Audi sharing the top four places with Pescarolo fifth but 3.5 seconds adrift. Look out for live streaming of the race on one of the European sites, and Radio Le Mans for live commentary.

Strange goings on at HRT, and not just in the driver line up. Colin Kolles is apparently leaving/being squeezed out, but he is the one that has the team and the workshop, so how is this all going to play out?

Daniel Ricciardo is on the fast track to an F1 drive, if driving an HRT can be called fast. Be careful what you wish for Daniel. Red Bull have bought Daniel a ride in the HRT Team to replace Karthikeyan, who will presumably get the ride back at the Indian GP later this year. So Helmut Marko wants Daniel to get more F1 seat time, but is not yet ready to ditch either of the Toro Rosso drivers. Who does Helmut want to groom Daniel to replace, that is the big question? I did ask a while ago when was the last time we had two Australians in a GP, if ever, and the answer was we have, but I think only once about thirty years ago in the Alan Jones era. I think the other driver would be Larry Perkins, but I am ready to be corrected.

Following the Red Bull pull out from NASCAR we now hear of another drinks company doing the same. Crown Royal has pulled the plug on the Roush Fenway team. Rats leaving a sinking ship?

A ship that certainly is not sinking is Le Mans and the ACO, with the announcement of the new World Endurance Championship, and now Porsche committing to build an LMP1 car for 2014. Not sure how you design a car for that far in the future the way the rules change, or why it is going to take so long? Porsche must have some information from the ACO on what those rules are going to be. Do we know? Is there some change that will take effect then? Anyway, presuming Peugeot and Audi are still running, and running diesels, we may see of the first time if what they have been saying is true, that a properly funded and designed car can compete with them without all the "equalization."

Talking of engines, no surprise here, the WMC ratified the V6 engine for F1 from 2014.

Exhaust blown diffusers employing fuel ignited in the exhaust pipes are to be banned in F1 from Silverstone onward. It has only recently been explained to most of us mere mortals that there are two types of blown diffusers. The original one cut the fuel and ignition on braking but kept the engine turning over so gas flow remained over the diffuser. Otherwise the extra downforce went away during braking which is not a desirable outcome. This is "cold blown" and as I understand the FIA stance is acceptable. What someone, probably Adrian Newey, worked out was that hot gas worked way better, so cut the ignition but keep the fuel flowing which now ignites in the hot exhaust and gives a large increase in downforce. This uses a lot more fuel, not very green, and can only really be used freely in practice and qualifying as the cars do not have enough to waste like this in the race, which might explain why Red Bull has a big advantage in qualifying which disappears in the race.

I think the FIA were struggling to find a way under the current regulations to ban this and so have come up with the "movable aerodynamic device" deal, the movable piece being the drivers right foot when he takes it off the throttle. Stretching a bit here I think, as does Red Bull who are not happy. They say they need the fuel flow to cool the valves. Funny they did not need it till now? Like all smart ideas it is very expensive and once discovered will be banned.

Lewis is off today playing car swaps with Tony Stewart who was a great open-wheel driver before switching to NASCAR and should enjoy the McLaren around Watkins Glen. Not sure Lewis will enjoy that tractor called a NASCAR. Let's hope they are not on track at the same time, they are likely to run into each other. Lewis' management denies looking for a new ride for Lewis, but this reminds me of Senna leaving McLaren because Williams had a car he could win in. Some odd characters in the McLaren garage and hospitality by all accounts, as one journo said "you can see where Lewis' head is at right now." What does Ron make of all this?

In all the excitement of the Le Mans 24 Hour a couple of things went unsaid. Aston Martin put on a worse display than the Jaguar last year and heads should roll for it. I don't know if the Audi engine guy is right in saying the engine configuration is all wrong, but something is badly wrong at Aston when you cannot do more than three laps in a 24 Hour race! They came out before the race and said that they would probably not last beyond 12 hours, what a great ambition. I know everyone will say its a new car, but both the Audi and Peugeot were new cars this year, the Audi only running one 6 hour race prior to this, and they managed very nicely thank you. It is not as if the Aston was ever on the pace when it was running, which for an engineering company is a sad indictment.

The other story is the ongoing problem of equality between petrol and diesel. The petrol cars were never in the race, way off the 2% and the faster refueling did not help much as the gravity fed flow could not match the increased size of the hose, nice one ACO. Now the diesel guys will keep saying it is because there is no one running a petrol car as seriously as they are, and if there was you would see it up there with them. There is some truth to this, we have not seen a similar effort with a petrol car, but just maybe it is because they know the current rules make it a waste of money?

The quote of the weekend was "it is a week's holiday at the end of which they run a race." And what a race we were treated to this year! Xan and I both had no trouble staying awake for the 24 hours. Fourteen seconds separated first and second, Audi and Peugeot, at the end of 24 hours. There have been closer finishes, but all staged. A slow down lap was added after the 24 hours were up as the last lap was full out racing, not the usual parade for the cameras.  You could say the race was won by the length of the pit lane, as that is what it came down to with both cars stopping with about 30 mins to go, the Peugeot just for fuel, the Audi for a dash of fuel but then new tires, so a longer stop and he got out 6 seconds in front, thanks to the Peugeot being at the opposite end of the pit and Audi being close to pit out.

All four classes saw some great tussles, most of them cleanly fought. I'm not sure I am happy about the antics of the Peugeot drivers, despite their claims they were innocent and it was down to bad visibility out of the closed cockpit cars. Davidson and Gene knew all too well where the Lotterer Audi was and being laps down on the Audi should have have had more respect for the leader. It is one thing to make things hard for the overtaking car, it is another to deliberately move over on him on a straight piece of road after you have just collided in the second chicane on the Mulsanne Straight. We had already seen all to graphically what happens when a car moves over on another at those speeds, and I for one expected better from Gene. I still have not forgotten Davidson putting the Corvette into the wall at the Porsche curves.

Yes the Audi guys were aggressive too, they had to be, and the changes to the rules had an unintended consequence. The ACO reduced engine size and air intake size to slow the LMP1 cars down, but in the usual fashion the engineers worked out how to recover some of that speed by reducing drag, and therefore downforce. So the cars were more on the limit when it came to cornering and avoiding traffic, and needed to keep up the momentum, so they took chances and had less control when they did not work out. We saw two massive accidents to the Audis which thanks to the design of modern cars both drivers survived with virtually no injuries. As I said a week or so ago, car design is where safety has improved. The walls and tires did their job too, especially for McNish's accident where there were a lot of marshals and photographers. We had two long safety car periods to repair damaged guard rail, and great job by the track to get it fixed, but it showed why I prefer concrete as the hits in the Porsche Curves with the Corvette and Ferrari required no repairs at all. Guard rail is made to give, and is probably a bit better for the drivers in that respect, but McNish almost went over the guard rail perhaps due to the fact it did give and provided a ramp?

Unlike almost any other form of racing Le Mans does not red flag a race except for exceptional rain or fog, so we saw a one hour and a two hour procession. They have three cars due to the length of the track, and this makes for some interesting strategy. The race goes on, albeit at a reduced speed, and a lot happens. Drivers make mistakes due to cold tires or boredom, teams with a slower driver take advantage of this time to put him in, therefore meeting the time requirements for drivers but not losing any time. Refuelling stops have to be made and tire changes can be done without the normal loss of time, but who is behind which safety car has to be considered, and when to stop. At the start of the period, yes if you are low on fuel, or at the end to maximise your next run and if you actually wait until the final moments you can actually make time as you can leave under green without waiting for the next safety car. Great strategy games.

The strategy between Audi and Peugeot was fascinating. This year Audi were the fast cars but used more fuel, so more pit stops. So which was better, a fast pace and more stops or a slower pace, relatively, and less stops? As it turned out there was no difference. 14 seconds in 24 hours, 0.016%! Tire wear also played a part. Audi, despite running faster could run four or five stints between tire changes, and the poor drivers did those stints too! The Peugeot although slower could only run three and sometimes four stints. Either way they ran about twice the distance on one set of tires as F1 does on three or four, so who's green?

The standards applied by the Stewards both here and at Montreal make me scratch my head. Robert Kaufman who made contact with Rockenfeller in the Audi in the dark and when taking the racing line, as the slower drivers were told, is ejected from the race. Gene who deliberately moved Lotterer over almost to the barrier in broad daylight while racing with him and on a straight does not even get called to the Stewards! Hamilton gets called to the Stewards in Montreal and Button who took him and Alonso out while winning the race does not? Now, that is probably due to the past problems of Hamilton as much as anything, but it is still inconsistent.

I did not see too much of the Canadian GP. After getting up at 5:30 on Saturday and staying awake until 7:30 Sunday and being emotionally wrung out by the Le Mans race, I went to sleep and set the alarm for Montreal. Speed had given the race over to Fox who dd their usual stellar job, starting the coverage as the race started despite a paid for ad being on the half hour prior, and thankfully for them it was behind the pace car due to the rain. I got up for this? We had the usual BS from Bob Varsha and the boys. This is network so we must have a whole lot of new viewers who know nothing about F1 so we have to talk to us like we are children. Then we start, and it is all crazy, Hamilton more than most, and the outcome was all too predictable. I personally thought Button put him in the wall, but I guess his explanation stands up, that would have been out of character. Then we had the red flag, so I gave up and went back to sleep. I wrongly thought Fox would give up after the mandatory two hour broadcast but apparently no. I'm glad I did not wait up though. I have read it was an exciting race, but from what I have read it was a crap shoot. Give me Le Mans every weekend.

The coverage of Le Mans was great. I had Radio Le Mans on one computer so had all the action and information on what was happening, not a load of infomercials, FromsportCOM.com live streaming on the TV via the other computer, and SPEED if I needed it, when they were actually on and following the action. The Eurosport Director went to the same school as the SPEED guy, he would at times rather show someone asleep in the pits or media center rather than two cars racing their hearts out.

Needless to say I did not watch the MotoGP or the WSBK, both predictably won by Casey Stoner and Carlos Checa respectively. Great gutsy ride by Colin Edwards though.

Finally a word about Lewis who is reported to have met with Red Bull's Christian Horner at the weekend. A very smart man, Warren Willing, told me years ago that when a rider or driver is struggling with a slow machine one of two things will happen. Either he will get depressed and stop trying, or drive over aggressively and crash. This seems to be the consensus for Lewis' problems at the moment. The McLaren is almost there, but never quite there when it comes to beating the Red Bull, so he tries to make the difference up by driving harder. It cannot be easy to watch Vettel in that car and know you could be there too.  Something needs to change before his career will be remembered as a great talent wasted. Maybe a change of team is it?
