An automotive straight line G-meter utilizes the input from a piezoresistive accelerometer to accurately measure and display both straight line forward and backward as well as lateral or side to side acceleration and deceleration of a vehicle. The automotive straight line G-meter includes solid state circuitry which temperature compensates and amplifies the transducer output before coupling to an analog meter that is calibrated to show the gravity effect of acceleration and deceleration of the vehicle. The G-meter device further includes circuitry for energizing an automotive tachometer that employs a LED (light emitting mode) bar graph to display the revolutions per minute (RPM) of the vehicle engine.
