Is a Speedometer Marked 260 Indicative of a Good Car? For example, the speedometer of a Mercedes-Benz A-Class car is marked up to 260 mph. Here is some related information about car speedometers: 1. Car Speedometer: The maximum scale on a car speedometer is called the "speedometer bottom." Generally, the maximum speed indicated on a car speedometer is the highest possible speed under the engine's no-load maximum RPM. Therefore, cars with higher speedometer bottom values usually have better performance. 2. Working Principle: The speedometer's indication relies on a speed sensor, which is installed on the transmission. Different rotation speeds generate different pulse signals, which are then converted into pointer output to display the current speed. Regulations require that the speedometer display a slightly higher speed than the actual speed for safety reasons. Another type is the LCD speed display, which works on a similar principle, except the output is displayed on an LCD screen instead of a pointer.
