The entry list for this year's Le Mans 24 Hours has altered due to a number of withdrawals and the promotion of five reserves just a matter of weeks before the endurance classic takes place over the weekend of 14-15 June.

The changes come in both the LM GTE and LMP categories, which see the integration of two and three newcomers respectively, while the Automobile Club de l'Ouest confirmed that there will be no fewer than 56 cars taking part in the official test day on Sunday 1 June.

The LM GTE category has been hit by three withdrawals, all featuring Aston Martins, as the #89 Aston Martin Racing, #87 Craft Racing and #96 Aston Martin Racing entries were pulled from the entry.

They will be replaced by two Porsche 911 GT3 RSRs, namely the #76 IMSA Performance Matmut and #79 Prospeed Comp?tition entries that featured on the initial reserve list.

However, with no further reserves left to promote in LM GTE, an additional LMP entry will be accommodated to retain the usual number of entries.

The #50 Larbre Comp?tition Morgan-Judd, the first LMP reserve, has now been added to the LMP2 entry, while the #42 Caterham Racing and #29 Pegasus Racing entries - featuring Zytek-Nissan and Morgan-Nissan combinations respectively - have been included as replacements for the two Mill?nium Racing entries originally listed as #22 and #23 in the initial line-up.

The Signatech-Alpine team had been second on the list of LMP reserves, but decided not to honour its entry with its #30 Alpine A450-Nissan.

There are now no entrants left on the reserve lists for the 2014 race, with the ACO confirming that 56 cars will be at the start of the 82nd event on 14 June, split 29-27 in favour of the sports prototypes.

Additionally, the ACO revealed that the list of teams present at the test day will also feature a change, with the #79 Porsche 911 GT3 RSR run by Prospeed Comp?tition replaced by an additional Ferrari 458 Corse fielded by AF Corse.
