Car with a Brain

Car with a Brain is the forty-seventh episode of the 1967 Speed Racer animated cartoon series.

Plot
For 22 years, brilliant scientist Dr. McFife had secretly developed a Monster Car that is controlled by an electronic brain. One stormy night on the Bonnie Hills of Scotland, he uses the lightning to gather up enough energy to power his massive creation. The moment that it was activated, McFife sends it out to wreak havoc on the countryside. The Monster Car plows through everything in its way, smashing through a village, past a police car, destroying the Bonnie racetrack, and shaking up the city where the Racers, Sparky, and Trixie are staying at their hotel. Not wanting anything bad to happen to the Mach 5 during the incident, Speed dashes off to the parking lot to reach his vehicle. As he prepared to get the high-tech race car out of the parking lot, he witnesses the Monster Car destroy the place.

Speed then goes off in pursuit, before being blown away by one of the gigantic vehicle's rocket thrusters, leaving him unconscious and the Mach 5 on its side. The Monster Car then destroys an entire tank battalion that had attempted to destroy it to no avail. More to come

Dub edits

 * Narration was added in several parts in the English dub that wasn't present in the Japanese version:
 * The opening when it shows over Scotland.
 * The ending when the narrator tells viewers on coming back for the next episode.
 * In Japanese, the country was a fictitious one that goes by Chacretz. The English dub changes it to a real country of Scotland.
 * McFife's reasoning for the Monster Car. In Japanese, he used to be a higher up at the Gelt Empire and the Car was attempt regain their power. The car was only used to destroy the country, and it was built by that empire. In English, he used to a scientist for Scotland until he became mad and wants to use it to destroy all over the world.
 * Speed's reaction about the Grand Prix being cancelled from the Monster Car was different. In Japanese, he was upset. In English, he was just disappointed and hopes it'll get rebuilt soon.
 * An extra scene of Dr. McFife in his cell with everyone looking at him was cut.
 * The general explains that the Monster Car is following a path that an army of soldiers from Gelt Empire took 22 years before by crossing the Strait of Bard. Sparky tells Speed about the conflict of Chacretz and Gelt Empire. In the dub, the conversation is about the design of the car, and Sparky remarking that McFife has a huge grudge against the city. Also, an overview of the room with the gang looking at the map was cut.
 * In the Japanese dub, Speed asks Pops if the Monster Car uses rockets. But in the English dub, Speed already found out that the Car uses rockets.
 * Pops tells Speed that the lighthouse was recently built and was over an old fort that belonged to the Gelt Empire, which the Monster Car was able to refuel as there was fuel underneath. In English, Pops just tell Speed about the importance of the lighthouse and doesn't know why the car was refueling until the two inspect the hole and figures it was used to be a fueling station for passing freighters.
 * After Speed was rescued by the army when he was chasing the Monster Car underwater, he tells Pops about the opening of the car. Though the dialogue between him and Pops was altered. In Japanese, Pops was rather angry that Speed disobeyed and says he'll disown Speed, with Trixie, Sparky, Spritle and Chim Chim looking very shocked and upset at the argument. The English dub has Pops telling Speed that they need to head back to tell the commander about the weakness. Because of this, the scene with Trixie, Sparky, Spritle and Chim Chim was cut.
 * The dialogue between Speed, Trixie, Pops and Spritle at the end. In the original, Speed asks Pops if he is gonna disown him because he went off to stop the Monster Car. Pop says no and instead says he'll disown Spritle and Chim Chim instead, with Spritle being upset. In the English dub, Speed just says he's happy that Spritle and Chim Chim were there to help him out, though Pops scolds at the two that they shouldn't wonder off. Spritle apologizes to Pops about.
