Give us an iPhone application that relates to cars and we're all over it. Apparently, so is the crew at Motive. They took out an Audi S5, mounted a Racelogic V-Box onto the windshield and brought along a Dynolicious-equipped iPhone to see how it stacked up.

The world has gone iPhone crazy since Apple released v2.0 of its sleek mobile device, and while GPS and 3G have been big draws, the multitude of available software apps in the new App Store has been the real wild card. One app that has us really psyched is a new automotive performance meter called Dynolicious from BunsenTech. It uses the accelerometer inside the iPhone to let you record 0-10 through 0-100 times, quarter mile and trap speed, Lateral Gs, horsepower and more. Results are also displayed in real-time on the phone itself with graphs and a speedometer. You can also configure the tool with updates to your car, weight, before and after performance measurements, and keep a complete history of all your runs.
