The entry list is packed out with Superstock teams (41 teams out of 64), but the focus on the track will be the Formula EWC entrants. Here's our pick of the crop:

YART- Yamaha Austria Racing Team: Jerman, Martin, Giabanni. 2009 World Endurance Champions, last years Le Mans winners and virtually unbeaten all season. They've found the formula for success and are now a force to be reckoned with.

SERT – Suzuki Endurance Racing Team: Philippe, Dietrich, F Foray. Seemingly unbeatable until last year, don't expect them to relinquish their endurance crown without a fight.

Folch Yamaha: Valcaneras, Rita, Font. Experience but small Spanish team who have improved year on year.

Bolliger Kawasaki: Saiger, Muff, Stamm. Swiss stalwarts who never give up. Will 2010 be their year?

Maco Moto Yamaha: Pridmore, Ribalta, Carasco. Slovakian team who have grown into a truly professional outfit.

BMW Michelin: Gimbert, Nigon, tbc. We've seen how the bike goes in SBK, but will that translate to endurance success?

RMT21 Honda: Weynand, Rot,h, tbc. Probably the most successful Honda team in the championship in the last five years. Not to be underestimated.

GMT94 Yamaha: Checa, K Foray, Lavilla. Back for the full season after failing to make a big impression in WSS or SBK, this is their home turf.

BMP Elf 99 Honda: Lagrive, Muggeridge, Cudlin. Each of this new Honda team's riders has something to prove; Lagrive and Cudlin also have the endurance experience; expect fireworks.

GSR Kawasaki: Da Costa, Four, Leblanc. Formerly Kawasaki France, they have a reputation for burning brightly but not for staying lit.

National Motos Honda: Scarnato, Barrier, Jonchiere. They pay for the Le Mans posters to be printed, but they can last the distance in the race?

Alf's Kawasaki: Godfrey, Barton, Montana. Experienced British team taking over from Phase One as the Brit fan's choice. Phase One will be concentrating on the TT, NW200 and Classic Endurance races this year. Go Alf's!
