Supernatural's Dean Winchester will be throwing punches from the back seat of the Impala during season 11.

The CW drama will pay homage to Sam (Jared Padalecki) and Dean's (Jensen Ackles) iconic '67 Impala in episode 4, which is aptly titled "Baby." Penned by Robbie Thompson, the highly anticipated episode will keep the brothers inside the car for its entirety - from battling baddies to catching some z's, it will all take place within the sleek interior of the Metallicar.

"We shot a fight scene on Tuesday [for "Baby"]," Ackles said at Creation Entertainment's Minneapolis Salute to Supernatural on Sunday. "There was a fight scene involving three people in the back seat."

The close quarters resulted in a lot of accidental bumps and bruises for all those involved, but that didn't stop Ackles from throwing in a little improv.

"I knock one of them out of the car and then I'm punching the other one and the camera was on me and, I don't know why, but all of a sudden I had a Clint Eastwood moment and I hit him the last time and I grab his collar and go, 'Get out of my car!'" Ackles teased.

Unfortunately, the actor has no idea if that take will make it to air. Considering how unfailingly appropriate the line is for Dean, it would be a shame if it were cut.

Catch up with Sam and Dean when Supernatural returns to The CW on Oct. 7 at 9 p.m. ET. Check out the Impala in the video below.
