The tachometer is located on your instrument panel, and tells you how fast your engine is moving, in terms of revolutions per minute (RPM). The tachometer is a semicircle, with a hand that points to a number. This number, times 1,000, is the speed of your engine (for instance, if the tachometer hand points to “4,” then your engine is operating at 4,000 RPM).
