This palm-sized computer measures a car's acceleration, horsepower, torque, and more, allowing you to determine if the vehicle is achieving its optimal levels of performance (play the video).

The 4 1/3" color touchscreen displays customizable gauges that measure 1/4-mile, 1/8-mile, and 0-60 mph times, and determines the braking distances at different speeds with the touch of a button. You can monitor the car's fuel economy and see how the miles-per-gallon data changes with different drivers.
