What does DTM mean?

1. The DTM is the world's highest level of touring car racing, second only to the Le Mans Series, and its cars are faster than those in the FIA GT1 class. The standard of drivers is also very high, many of them are former F1 drivers. Currently the DTM is basically a battle between Mercedes-AMG and Audi, with Opel having long since withdrawn. The so-called Masters is a translation of the last Masters in the DTM's full name, Deutsche Tourenwagen Masters.

2, all except GP2.GP2 is a Renault-funded event, but is heavily supported by the FIA, and is now basically run in tandem with F1, with GP2 races held at the same venue a few days before F1

3, not the same at all.

WTCC uses racing versions of everyday small car conversions, such as the Mini CooperS, Chevy Cruise, etc., while FIA GT uses racing versions of what we often call supercars, such as the Lamborghini Murcielago LP670R-SV, Maserati MC12, Nissan GT-R R35 GT500, etc. The LeMans series is somewhat similar to the FIA GT and is also divided into LMGT1 and LMGT2 classes, but there are two differences, all LeMans classes compete on the same track, which is different from FIA GT's separate races, and the other most significant difference is that LeMans also includes two prototype classes, namely LMP1, LMP2, of which the LMP1 group is the strongest, basically can be regarded as a formula car in the garb of touring car racing, straight performance even more than F1, should be the strongest performance of all the touring car racing car group, for example, Audi R10TDI is the famous champion car that has dominated the LMP1 group for several years.
