Despite beating Verstappen in European F3, Briton changes career path to German V8 tin-top series.
Formula Three European Championship runner-up Tom Blomqvist will race in the DTM this year after securing the final drive available with BMW.
Blomqvist finished second to Esteban Ocon in the European F3 series – and ahead of Toro Rosso Formula One driver Max Verstappen – in 2014.
The son of Swedish rally legend Stig, Blomqvist had tested BMW's M4 DTM car in December.
He joins reigning champion Marco Wittmann, Maxime Martin, Augusto Farfus, Bruno Spengler, Martin Tomczyk, Timo Glock and Antonio Felix da Costa in the Bavarian manufacturer's 2015 line-up.
"I cannot put into words just how delighted I am to have been signed up by BMW Motorsport," said Briton Blomqvist, 21.
"After the test in Spain, I was able to envisage just how it would feel to be a BMW works driver and regularly push myself to the limit in the BMW M4 DTM. Now I have the opportunity to do just that – and it's just fantastic. I'm really proud to be a member of the BMW Motorsport family now."
BMW motorsport boss Jens Marquardt said Blomqvist's performance during his first test at Jerez had left his convinced he will be strong right away.
"Tom was extremely impressive at the test in Jerez, and comes to us with a wealth of experience from Formula Three," he said.
"I am confident he has everything he needs to find his feet quickly in the DTM. With his likeable personality he is definitely a great asset to our line-up. We have done well with our choice of rookies so far."
