Here is a table comparing the specifications of two popular models of Auldey Mini 4WD cars and Tamiya 4WD cars:
| Feature | Auldey Mini 4WD | Tamiya 4WD |
|---|---|---|
| Motor | Mabuchi RS-540SH | Tamiya RS-540 Sport Tuned |
| Gearbox | 4:1 | 3.5:1 |
| Body | Plastic | ABS plastic |
| Weight | 150 grams | 180 grams |
As you can see, the Tamiya car has a more powerful motor, a better gearbox, and a lighter body. This gives it a significant advantage over the Auldey car in terms of speed.
Of course, the Auldey car is not without its advantages. It is less expensive than the Tamiya car, and it is also easier to build and maintain. Additionally, the Auldey car is available in a wider variety of colors and styles.
Ultimately, the best way to decide which car is faster is to test them out for yourself. If you are looking for a fast and competitive car, then a Tamiya 4WD car is a good choice. However, if you are looking for a more affordable and user-friendly car, then an Auldey Mini 4WD car may be a better option.
