Since the race is coming up (June 11-12) I thought I would start a thread.  For those that are new to endurance racing, I'll give a quick overview.

For those that want more info, there's a wiki page on it.
http://en.wikipedia.org/wiki/24_hours_of_lemans

Or, you can go to the official site...
http://www.lemans.org


The 24 Hours of Le Mans is one of the oldest races dating back to 1923.  It has changed a lot over the years and even once used to be a part of the Grand Prix calendar.  The track is still basically the same as it was in 1923.  It is almost 8.5 miles long with countless corners and elevation changes.  The track is mainly run on public roads, but does have a small section that is part of a permanent racing track.  As it's name implies, it is run for 24 hours.  The cars will complete over 3,000 miles before they are done...the car's that make it to the end anyway. 




Modern Le Mans
There are four classes of cars from two categories that race at Le Mans now.  You have "Prototypes" which are broken up into LMP1 and LMP2 classes.  You also have "Grand Touring" cars which are broken up into GT1 and GT2 classes.  This is a little different for people used to other forms of motorsport such as Nascar, Drag Racing, Spring Racing, etc.  There are actually four different races going on at the same time.  They all start at the same time and finish at the same time.  At first it's a little confusing, but as the race unfolds and you get used to it, it's a lot of fun. It's like watching four action movies at the same time!

Here are the details for each class:

LMP1


Open or closed cockpit prototypes made by Audi, Aston Martin, Orecas, Lola, Peugeot, etc.

•Minimum weight: 900kg for petrol-fuelled cars and 930 kg for diesels
•Wing length: 1m60
•Maximum engine capacity: 6,000cc for petrol atmospheric engines, 4,000cc for turbo engines and 5,500cc for diesel engines
•Maximum disc diameter: 38cm
•Tank capacity: 90 litres (81 litres for diesel engines)
•Headlamp beam: White
•Race numbers: 1-24
•LMP1 Category sticker: red




LMP2


Lighter and less powerful than the LMP1s, the LMP2s can also have either open or closed cockpits.  Manufactured by Porsche, Mazda (Lola for the chassis), Essex, etc.

•Minimum weight: 825kg
•Wing length: 1m60
•Maximum engine capacity: 3,400ccs and a maximum of 8 cylinders for atmospheric engines or 2,000ccs with a single turbo and a maximum of 6 cylinders for turbo engines
•Maximum disc diameter: 38cm
•Tank capacity: 80 litres
•Headlamp beam: White
•Race numbers: 25-49
•LMP2 category sticker: blue



GT1 (Now Called "GT Endurance Pro") & GT2 (Now Called "GT Endurance AM")



This has been my favorite category as far as wheel to wheel racing goes. They have changed this group up a bit this year, but it should still provide some great racing.  This is where you'll see the Corvettes battle Ferrari, Porsche, Lotus, BMW & Aston Martin.


How to watch or listen:
Live coverage from SpeedTV starting at 7:30 AM on June 11th.  They don't cover all 24 hours of it, but they do several large chunks.  I tend to listen to Radio LeMans in between.
6/11  7:30 AM - 10:30 AM - The Start of the race.
6/11  2:30 PM - 7:00 PM
6/11  10:00 PM - 6/12  8:30 AM

You can go to Radio LeMans and listen to flag to flag coverage.  I actually listen to them throughout the year as well just to get the latest news.

Some years they will have live coverage from lemans.org as well, but I don't think they are this year.

Thanks for all of the info.  Since you put the Vette picture above the Ferrari, I guess that's who you want to win?

Well, Forza Chevy doesn't have the same ring to it that Forza Ferrari has.  If the Corvettes were red and were sponsored by the Razorbacks, then hell yeah!

On a side note, Michael Waltrip will be driving for one of the Ferrari teams this year at Le Mans.  I can't remember the last time that a Nascar guy dipped his toes into propper endurance racing.  I'll be cheering him on though.

Here's a full entry list if you're interested.

Here are some onboard laps from 1955-2010 to show how much it's changed over the years (and how much it hasn't).  Check out the sound of the Porsche prototypes in 1977 and 1982.  Absolutely amazing!

first paragraph of wiki:

The 24 Hours of Le Mans (French: 24 Heures du Mans) is the world's oldest sports car race[1][2] in endurance racing, held annually since 1923 near the town of Le Mans, France. Commonly known as the Grand Prix of Endurance and Efficiency, race teams have to balance speed against the cars' ability to run for 24 hours without sustaining mechanical damage to the car and manage the cars' consumables, primarily fuel, tyres and braking materials. The endurance of the drivers is likewise tested as drivers frequently spend stints of over two hours behind the wheel before stopping in the pits and allowing a relief driver to take over the driving duties. Drivers then grab what food and rest as they can before returning to drive another stint. Today it is mandated that three drivers share each competing vehicle.

If you are talking about the yellow line and dotted lines on the map, the dotted line is the outline of the small "Grand Prix" circuit.  Though, it's not used for F1 or Grand Prix racing it is used for MotoGP and some Grand Touring racing.  The yellow line is showing a part of a highway that makes up a part of the track.  The track is the black line.  You can see on the yellow line where they have dedicated sections to avoid the round-a-bouts as well.

This is a much clearer map of the circuit...though rotated a bit.

That sharp corner is called Arnage if I'm looking at the same thing as you.  It's the slowest corner on the track.  Obviously different classes of cars take it at different speeds, but I think the prototypes are around 50-60 mph.

And they will change brake pads at least once during the race.  That kind of thing is part of what makes endurance sports car racing so interesting.

Arnage is surprisingly difficult.  You have just come off of a fast right hander into the left hand 90 and the right 90 comes up really fast.  On top of that, it's always dirty with dirt/grass/gravel that gets kicked up from running over the curbs.  You see a lot of spins there throughout the race.

Here's a great clip at night of Arnage...

Sir Stirling Moss has just stepped out of the car at the Le Mans Classic and said that it is the last time for him to drive a racing car.  I know it had to happen eventually...he's 81.  I'm still sad though.   sad

I'm too young to have watched him during his real career but he was obviously quite a gifted driver.  And a gentleman...and those two things don't always go together.

By the way, Patrick Dempsey just went round in the old Mazda 787B that won Le Mans back in '90 or '91 (I forget).  My god, I forgot how good that thing sounded!  It sounds like an old Ferrari V12.

I cannot believe that Allan McNish walked away from this crash, and that none of the media people behind the fence weren't seriously injured by the debris.  I hate seeing crashes like this.

Thank God they chose to go with a closed cockpit car this year.  I don't think we would have McNish or Rockenfeller anymore if they still had the open cockpit design.  I seriously thought he was dead when I saw that.  Then Rocky's crash happened and I thought "there's no way they can be that lucky twice!"  I guess it was engineering and not luck that saved those guys.

Audi has built one hell of a race car this year!
