What is a Speedometer?

The purpose of the speedometer is to indicate your car's speed in miles per hour, kilometers per hour, or both. Even in late-model vehicles, an analog device uses a needle to point to a specific rate that the driver reads as a number printed on a dial. 

As with any emerging technology, the first speedometers were expensive and available only as an option. It wasn't until 1910 that the car manufacturers began to include the speedometer as standard equipment. One of the first suppliers of speedometers was Otto Schulze Autometer (OSA), a legacy company of Siemens VDO Automotive AG, one of the leading developers of modern instrument clusters. The first OSA speedometer was built in 1923, and its basic design has not changed significantly for 60 years. In this article, we're going to look at the history of speedometers, how they work, and what the future holds for the design of speedometers.
