Speed Racer Anime 1967

Speed and Trixie learn that the Mammoth Car is the gold smugglers, but they fall into a trap. They are saved by a masked racer and pursue the Mammoth Car as it attempts to escape.

When Trixie was granted the position of Speed's assistant in the No Limit World Race, Inspector Detector and his officials search each entry looking for $50 million in stolen gold bars before the race begins. When The Mammoth Car enters the track, its driver gives the Inspector a tour, giving no single trace of the gold. When the race begins, the Mammoth Car forces everyone off the road and even causes a massive train derailment, making Speed a bit suspicious. On its way to discover the Mammoth Car’s secret, he equips the homing robot with X-ray film so he can be able to penetrate the metal. The robot is shot at and returns home broken. Now, the Mammoth Car catches up to Speed and forces the Mach 5 off the road. When a ramp is lowered, a squad of motorcyclists descends onto the road. Racer X appears and spills oil on the road, causing the bikers to crash. At the airport, Spritle and Chim Chim stow-away aboard on Cruncher Block's airplane. Meanwhile on the road, the Mach 5 and the Mammoth Car both collide and veers off the road towards the forest. While Speed uses his rotary saws to cut down the trees, the Mammoth Car's power mows its own path. Speed turns around and tries to slash the car’s tires, but the Mammoth Car dodges it and encircles the Mach 5. Guns emerge from its sides. Speed closes the cockpit to block the shower of bullets and escapes through a gap and plunges into a lake.

Speed now avoids a collision with Tongue Blaggard's motorcyclist squad. Tiny, Blaggard's sumo bodyguard knocks Speed out. Coming up with a plan to save Mr. Klepto form Tiny, Speed reveals to Blaggard the location of the $1,000,000,000. Speed phones Pops and gives him a message for Trixie: Forget about the $650 ring, it's a signal for help. Guarded by Blaggard's men, Speed heads to Misty Valley using his Mach 5 where the $1,000,000,000 is located. Speed tries to radio for help. Blaggard stops him and he accidentally sends the homing robot back home. At the Racer home, Trixie who was stood up by Speed, wakes up Pops. Spritle gives the blame to the homing robot for waking him. Trixie rushes off to search for Speed.

Speed Racer, Spritle, and Chim Chim go out for a test drive for the Mach 5. The radio makes an announcement that Tongue Blaggard made an escape from prison. The Racers meet a girl and her grandfather whose Model T racing car broke down on the road. Speed offered to help out, but the old man declined. Later on, the racers find the broken down Model T again. Now the old man changing his mind, he accepted Speed's help. While the racers dine with the old man with his granddaughter and his adopted children, Blaggard steals the Model T Racing Car, trying to hope that it once belonged to the crook, Fingers Clepto. With the car stolen, Speed vows to bring back the stolen car back. Unashamed, the old man reveals who his father was. Trixie in her helicopter spotted the stolen Model T and brings it into Pops' garage for minor repairs. Longer than ever, a line of Model T's formed with engine trouble. Speed finds it very strange and uncovered the old man's original engine, finding a secret code number etched on it from Light Fingers Clepto who's the old man's father. On his hideout, Blaggard recalls his encounter with the inmate who told him about the Model T vehicle's secret engine number that leads to the loot. Making a decision to bait Blaggard, Speed adorns the Mach 5 using a flag to bear the engine's secret code. Blaggard's men follow him while a cargo helicopter flies ahead. The thugs set a fire on Speed and the old man, until Racer X arrives to defend his brother. Instead, he ends up on the edge's cliff. The helicopter lowers a ramp to unload a squad of weapon-carrying motorcyclists.

Speed was saved by a masked racer who is revealed to be Speed's older brother, Rex Racer. When Speed was at Rex's house, he was mistaken for Rex and kidnapped by intruder.

Introducing Speeds older brother Rex Racer.

Speed continues his race, and the robbers continue their attempts to capture Speed.

After winning a practice race, Speed Racer is offered a driver position on the factory racing team owned by the company who employs his father, Pops Racer. Speed declines the offer because Pops is opposed to him becoming a professional driver. Meanwhile, Pops resigns his engineering job with the factory after an argument with chief engineer Mr. Van Ruffle during a board meeting where the board rejects his plans for improving the Mach 5 with a new engine. While Speed drives Pops home, a gang of thugs on racing bikes snatch Pops' briefcase with the plans. Speed jumps from bike to bike trying to get the plans back but fails. He spots Trixie overhead in her helicopter and radios her to pursue the thug with the plans. She buzzes him, forcing him to drop the briefcase and crash off the edge of the mountain road. Speed recovers the briefcase. That night at the Racer home, Pops plans what he is going to do now that he has no job. He decides to remodel the Mach 5 himself, but doesn't know how he'll come up with the money he'll need. Later at Van Ruffle's house the thugs explain how they failed to get the plans. Ace Deucey crashes the meeting and makes a deal with Van Ruffle to steal the plans for $5,000. The next day Speed visits Sparky to let him know he is selling the Mach 5 to help raise the money Pops needs to build the new engine. Sparky suggests that Speed should enter the Sword Mountain Race (Japanese: 山つるぎ Mt. Tsurugi) for a $5,000 cash prize, and Speed decides to enter the race. Meanwhile Ace pays a visit to Pops at the Racer home. Ace pulls a gun and starts searching for the plans but doesn't find them. Speed arrives and interrupts him. Deucey leaves vowing to come back for the plans. Deucey didn't find the plans because Pops has hidden them on a spare windshield using invisible ink.
