The LEGO Cars theme was introduced in 2010 for DUPLO and licensed by Disney and contained sets for Cars and Cars 2. In 2011 it was transferred to the LEGO System brand. In 2012 was temporarily discontinued. After the release of Cars 3 the theme was reintroduced in 2017 as a subtheme of Juniors and some of the returning characters' designs had slight changes to comply with the Juniors theme. The sets feature characters and scenes from all 3 of the Disney Pixar's Cars movies.
2011 LEGO Sets
For collectors, 2011 was a significant year in that LEGO released the first Internal sets Moulding Machines (4000001) and LOM 2011 Moulding (4000002) which have paved the way for high value future collections. A few notable themes introduced in 2011 were Ninjago, Winnie the Pooh, SpongeBob SquarePants, Alien Conquest and LEGO Master Builder Academy. Of course LEGO Ninjago set the stages for a decade of collecting. However, in 2011 LEGO also discontinued a number of themes which included Ben 10, Power Miners, Toy Story, Prince of Persia, Space Police III, BrickMaster and the loved Trains theme.
