GX2 Performance Meter

Beltronics Performance Timer

Further, if your top speed for a given run was less than 60 miles per hour, the GX2 will tell you your time to the highest "even-10mph" speed. For example, if your top speed was 34 mph, the GX2 will calculate and display your 0-30 mph time. It does all of this automatically, requiring no programming or intervention by the end user - how cool is that?

Reviewing run results is simple, thanks to the 10-run memory and the easy to use up/down navigation buttons. The GX2's run-data memory is also retained in the event the unit is powered off, another welcome and handy feature.

The GX2 ain't no one-trick pony - no sir. In addition to recording straight-line times and speeds, it can measure cornering forces (your own personal skid-pad), braking distances, horsepower and much more. And just like the acceleration tests, utilizing these other features is simple and straightforward.


We decided to utilize my 2002 Volkswagen GTI 337 as the official test mule for the Beltronics VectorPro GX2. With a snappy 1.8-liter turbo that's benefited from a few aftermarket goodies, a six-speed transmission and large 18" wheels wrapped in sticky Michelin Pilot Sport tires, it seemed the most logical choice.

We moistened the suction cups, stuck the unit to the windshield, pressed the calibration button and set about conducting various runs and measurements. Ambient conditions were ideal - air temperature was 58 degrees Fahrenheit with 31% humidity. Perfect testing conditions.

We also went through the GX2's G-Meter options to set the vehicle's weight, determine the coefficient of drag (this provides a more accurate horsepower calculation) and tweak a few other settings, based on our past experiences with fifth-wheel measuring devices. Total time to complete the installation, calibration and set-up: 2 minutes, 8 seconds.
