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?

Great pictures and commentary on www.fromsportcom.com of the first free practice and qualifying. Pictures are Eurosport with very few and short ads, and commentary is out friends from Radio Le Mans. They have 24 hour coverage of the race itself so I know what I will be watching. Peugeot just on pole at the moment from the three Audis. Top seven all diesels and the best petrol is Pescarolo 5.5 secs off the pace of the slowest diesel. The ACO intent is for the petrol cars to be within 2%, which would be around 4 secs, so getting closer, and they have some breaks which in the race may even things out. Lets hope so. Still, the times between the diesels is close and we should have another cracking battle.

Some big accidents, especially the Straka which leads the LMP2 class again this year, but all are repaired I believe. BMW's leading the way in the GT Class which is a big improvement on last year. Fisichella stuck in a quick lap at the end in the Ferrari 458 to split them, and then the Corvettes who had a bit of a fraught session. Let's hope all their problems are sorted.

Meanwhile, back in Bahrain the head of the Tourism Board called Bernie a hypocrite for changing his stance on staging the race this year. That's pretty rich for a group who say all is peaceful while they put 47 medical staff on trial in a secret court behind closed doors. Adam Parr, CEO of Williams, has come out and said we cannot change India's date, all his neighbors have booked their holidays. Nice way of saying we are not going to Bahrain without actually having to say it, no guts. So, if the FIA needs to 100% agreement of the teams to change the calendar then they are now officially in trouble.

Joe Saward can always be relied upon for some  good sensible comments and today is no exception. Read his two pieces about the situation:

Great live streaming pictures and sound from SPEEDTV.com this morning. Wish I could watch all the F1 like this, no ads, no idiot commentary, maybe ALMS has something here. No picture break up or lock up, and the quality was better than cable. Two interesting sessions today with some big accidents, two at the chicane after the tunnel. Rosberg lost the back end under braking and took off over the speed bumps put into the center of the chicane, presumably installed to slow cars down that short cut it. Thankfully these were removed before qualifying as they actually only make it worse, as demonstrated . I for one did not expect to see Rosberg back out in quali, not that he was hurt, he missed the center island between the track and the run-off, but the car had substantial damage. Great job by the Mercedes team to have him not only back out but competitive. Perez was not so lucky in Q3, hitting the island side on, and thankfully he did, a head on would probably have him under the TECPRO barrier. The jury is still out on these compared to tires, and they cost many times more. For me they are too light, as we have seen already cars go under them. Perez will miss tomorrow's race but fortunately his injuries are relatively minor.

Unlike the two HRT cars who despite not turning a wheel in qualifying have been given the OK to race, and they did not even have to buy a starting spot! The Stewards in an unfathomable piece of generosity will let them race, despite being 6-7 seconds off the pace in practice. Now on another track that may be OK, but around here there is no place for sentiment, and no room to overtake. Let us hope that decision does not turn around and bite someone.

Perez's accident showed the absolute necessity to get out early and bank a lap in these short sessions. McLaren failed Lewis and now he is stuck down in seventh despite being fastest in Q2. As I suspected, no one tried to save tires, starting position is everything here. It will be interesting to see what McLaren's pit strategy will be to try and leapfrog Lewis up the field.

I commented the other day on the efficiency of the Monaco track team in repairing the asphalt, and it was in evidence again today. Most of these incidents would have taken lesser crews a long time to clean up, and in some cases may not have repaired in time to finish a session. Indy, NASCAR et al need to go there and see how they do it. As Michael Schumacher was crashing Thursday at Ste-Devote you could see the crane operator start up. Having said that the "crest" coming out of the tunnel seems to have contributed to a few accidents this weekend and needs addressing. Given their usual rapid response it is surprising it was not planed smoother during yesterday's quiet day.

In other news it seems the Lotus sponsored Renault team is in a spot of financial trouble. The Marussia money is not flowing and since Kubica's accident interest from new sponsors has all but disappeared. The Geni Capital deal was a novel one for starters, and Lotus Cars is another work in progress. maybe Tony Fernandes just needs to wait this out. Story is Renault is owed big time for engines and may be looking elsewhere for 2012, like Williams.

I did miss a race from my list yesterday. The World of Outlaws Sprint Cars were at Charlotte last night, but got rained out anyway. Rescheduled for tonight, but will only be live streamed. Kimi qualified 15th for the Nationwide race! Outqualified not only his mentor Kyle Busch but his car owner Joe Nemechek! Need to watch that tonight.

Ferrari have now expressed their concern at extending the calendar to accommodate Bahrain. Has no one the guts to come out and say they will not go? I for one will not watch it if it is reinstated and encourage others to do the same. That is the only message Bernie and his cohorts will understand. This would be almost the last straw for me and I hope many others about what has become of our sport.

It took Kimi to make me watch the NASCAR Camping World Series! Me and a lot of others I suspect. Watching him out on a mile and a half tri-oval for the first time I thought he did really well, although the truck was so loose it looked like rallying at times. Still, his reflexes and ability kept it on the track and tonight's race should be fun. You have to admire the guy, just like the old days when F1 drivers drove everything and raced every weekend, sometimes two races a weekend in Europe and America. F1's loss is the world's gain.

The really big news of the weekend for me is the ACO moving to live up to it's regulation on parity between the diesels and petrol cars. Petrol cars will have an air restrictor increase of 0.3 mm and can lose 10 kg, and if they cannot take weight off the car then they get a 0.5 mm increase. In addition the fuel hose for the petrol cars is increased by 10 mm, nearly half an inch, and the diesels decreased by 0.3 mm, so faster refuelling for the petrol cars. The ACO have made the changes after seeing all the new cars in action at Spa for the first time, and believe they will allow the petrol cars to do an extra 5 laps during the 24 hours. The older ORECA Peugeot benefits from a 15 kg weight reduction. It will be interesting to see how all these pan out in a few weeks time.

F1 is in Barcelona and not much has changed, Red Bull and McLaren on top with Alonso and Ferrari fifth. Mercedes big step forward has not improved their position. News is that Williams are the team that pushed the FIA to act on the engine mapping, but it seems that Cosworth are the problem in not being able to match the big guys. The top teams are of course resisting any changes, as they are the new engine for 2013. The opposition to the change to 4 cylinder turbos is growing, with Renault apparently the only manufacturer now in favor, for obvious reasons. Talking of Renault, the big rumor from Barcelona is that Kubica has signed to drive for Ferrari, the latest in a long line of drivers similarly rumored to go there. Massa must be feeling very unloved, despite Montezemolo telling the world Massa will drive for them next year. He did not look very happy with the car during practice.

The gap between the teams seems to be growing, with HRT still 7 secs off the pace, but then Lotus and Force India are around 4 secs off, and so on up the order. Alonso is a second off, and you quickly get to 2 seconds around tenth place. On these times the HRT are in danger of not making the cut at their home race, but I guess with Q1 times on hards they may make it. Lotus seem to have made the jump across the gap to the midfield teams, only to see the front of the pack just as far away as ever.

I was resigned to listening to the Spa 6 hour race this morning on Radio Le Mans, but thanks to Greg Sarni and his buddy I was told where to find a live stream of the race. It was on a web site I had not heard of, no surprise there, and I think it was a German TV feed, so listened to John Hindhaugh and his mates anyway. It is an amazing lack of vision on the part of TV stations in the US that races such as Spa, with the best cars in the world competing, on I think the best track, are not given any coverage whatsoever. We all know SPEED has gone the way of pandering to the lowest common denominator, i.e. NASCAR fan, but what about espn3.com who are streaming the ALMS series, and just about any sporting event on earth? Versus thinks it is a sports channel, and is there no one out there who can go back to where SPEED started and launch a channel for race fans? I know someone will say there is not an audience for it, but how did the original SPEED gather enough audience to make Fox want to buy it?

It makes no sense to me for the whole endurance race series not to be shown. It would be like showing one F1 race a season. Or one football match. How are you going to build or keep a fan base if you are not showing the whole series? Is SPEED covering Le Mans this year does anyone know?

More to the point this situation shows a complete lack of vision by the ALMS management. If your two key races that you promote, Sebring and Petit, are rounds of the Intercontinental Cup, the unofficial world sportscar championship, why on earth would you not do a deal for coverage of the other races in that series? You wonder why sports car racing is dying in the US. If the FI Teams think the series owner needs to do more to promote it, come and look at what is not happening here!

Peugeot won the Spa race by the way, a reverse of last year at Le Mans where they were fast and fragile, and Audi not quite as fast but luckier and reliable. Good race right through all the classes and down to the wire in most. Ferrari won the GT battle but BMW kept them honest, with Porsche in trouble. The winning Peugeot also won the "green challenge." And why not? As I have been saying, there is no need for another trophy, racing is about maximizing efficiency, so the winning car should by definition be the most efficient, especially if it is a diesel. Let's stop this pandering to the greenies and PC, or should I say BS.

Biaggi wrapped up pole at Monza with Checa still way off the pace. Troy Corser found some pace, or enthusiasm, to put himself on the front row, so tomorrow should be interesting.

Turkey threw up few surprises. I was not surprised the Red Bulls did not go out again in the final Q3 session. It was worth the very small risk one or two guys were going to pip them for the front row to have an extra set of tires. Not sure that this is F1, but it is today's reality. Rosberg followed up his China performance with third on the grid and the Mercedes crew are getting on top of the car set up. Williams lifted their game, but not soon enough to save Sam Michael and co, but Sam says he already has something lined up. Virgin's supposed corner turning upgrade left Glock behind the HRT! Nice going Nick. Lotus are clawing their way closer to getting out of Q1, and it will be fun to watch Kobayashi doing a "Webber" from the back tomorrow. He is a demon overtaker anyway, so watch your mirrors boys.
