Deutsche Bank analyst Rod Lache on Monday wrote that Tesla will sell almost as many cars as both BMW and Mercedes by 2030.

At that point we assume a terminal growth rate of 3.0% (in 2030 and 7.5% in 2021), and terminal margin of 9.5%," Lache wrote in a note.

The firm increased its price target on Tesla to $240 from $220.
