Le Mans Ultimate V1.4.2 patch notes: Over 90 new liveries and online fixes dominate new update

It’s hoped this will finally solve a litany of multiplayer bugs, which even forced sim racing platform Low Fuel Motorsport to cancel its blue-riband Pro Series competition. 

Whether this turns out to be a conclusive fix remains to be seen, however, with a 12 Hours of Le Mans test race scheduled for the 25th September set to offer clues.

New liveries

The update includes over 90 new liveries, including paint schemes from the 2026 ELMS and 24 Hours of Le Mans. This means all the LMP2, LMP3 and LMGT3 cars from this season are now selectable in-game, with the championship selectable as a single-player ‘Race Weekend’ option.

Although Hypercar liveries from Le Mans were added in V1.4, they are now joined by their accompanying LMP2 and LMGT3 paint jobs, thereby completing the grid.

Online Championships change

An interesting facet of the changelog reads: ‘Added support for bespoke online championships available to non-RC subscribers for limited time events’. 

Intriguingly, this suggests that one or more online championships, once the preserve of RaceControl Pro and Pro+ subscribers, may be opened up to include all LMU players in future. Quite what this will entail or how it will operate is unclear, but MSG is set to announce more details soon.

Other

A huge number of bug fixes and improvements have also been deployed, with the full changelog listed at the bottom of this article. Highlights include penalty options being added to the Engineer role’s pit menu and, perhaps most notably, AI cars should no longer perform bizarre manoeuvres when leaving their pit boxes.
