The chairman of Toyota (TM) just took a shot at Tesla (TSLA) .

Takeshi Uchiyamada, the chairman of Toyota Motor Corp, has criticized Elon Musk's electric automaker company, saying that mass battery production in cars is not ready and that Tesla should not be viewed as a role model.

"Battery-powered cars with a long range are very expensive and it takes a long time to charge them," Takeshi Uchiyamada told German publication Der Spiegel, first reported by Reuters. "Such cars do not fit in our program."

"Tesla is not our enemy and not our role model," Uchiyamada said. "I think it's the German manufacturers that rather see Tesla as a competitor," Uchiyamada added.

He also stated that Toyota was developing a new solid-state battery, with the ability to harness more power and recharge more quickly than current standard models.

"This technology will be a big development step. But that will still take time. We expect mass production in four to five years."

His comments come as Tesla unveiled its first electric semi-trucks along with a new roadster.

Shares of Toyota were falling, while shares of Tesla were rising over 1.5% in afternoon trading on Friday.
