1) Mazda 787B
The Mazda 787B is a legendary race car that became famous for its smart engineering and impressive race performance. One of its most special features was how the radiator was moved to the front of the car to improve cooling and airflow.
Before the 787B, earlier Mazda race cars like the 767 had radiators placed beside the driver’s cockpit. This setup worked, but it wasn’t the best for smooth airflow or maximum cooling when the car was moving fast on the track.
In the 787B, Mazda’s engineers decided to place one large radiator at the very front of the car’s nose. This helped bring in cool air from the front and push the hot air out through the top, making cooling more direct and effective.
To help the airflow even more, they added something called a Gurney flap at the top of the exit vent. This little piece improved the car’s front-end downforce, helping it stay stable and firmly planted to the ground during high-speed racing.
By moving the radiator to the front, the car no longer needed side vents near the doors to bring in air. This made the body of the car cleaner and smoother, which also improved the car’s aerodynamics for better speed and performance.
To keep the rear part of the car cool, especially the engine and brakes, Mazda added extra air intakes above the exhaust vents on the sides. These helped pull in enough air to keep the back of the car running safely without overheating.
Even though the Mazda 787B was a race-only vehicle and never sold to the public, its smart cooling design made a big impact.
