When talking about cars, a tuner is a car with many parts changed so the car can go very fast. The word "tune" here means "to adjust" or "to change". Typically, people call Japanese fast cars "tuners", compared to American fast cars, which are called "muscle cars".
When people want to drive fast cars but don't want to buy a very expensive car, they change some parts for an ordinary car to make it go faster.
Making a tuner[change | change source]
For basic tuning, the engine intake and exhaust are changed, which means the process that takes air into the engine and out of the engine happens faster. People can also make the frame of the car stronger, to help it go around corners better. A spoiler or wing helps air push the car down onto the ground, which means more grip.
Some types of tuned cars[change | change source]
- A hot rod is a classic American car with lots of engine upgrades to help it go fast in a straight line.
- A lowrider is a very low car, often with fancy paint and decals. Lowriders are popular in the United States.
- JDM means "Japanese domestic market" and is used for cars that are made for Japan before being brought into other countries.
