The DTM has revealed the numbers the drivers will use from the 2015 season following a change in the regulations to match Formula One-style numbering.
From this year, drivers are able to pick the preferred number with which they will race during their DTM careers, in a similar move to what F1 introduced for the start of last season.
Like in F1, #1 will be reserved for the defending champion if he wants to use it, and 2014 title winner Marco Wittmann has chosen it.
"I will enjoy every single race with the #1 on the car," the BMW driver said. "Hadn't I won the title, I'd opted for racing with the #11 on my car."
Audi's 2013 champion Mike Rockenfeller has picked #99.
"The 9 always was a good number for me. And so I thought that things just can't go wrong with two nines on my car," he said.
