We’ve seen some pretty cool iPhone implementations recently, such as those that emulate garage door openers or media managing remote controllers, but this takes the cake. Jonathan Oxer has written an iPhone application that can interface with his 3G equipped Mazda RX-8. The application allows him to lock/unlock the doors, start the engine and even pull real time dyno stats from the car!

As for the RX-8, it’s wired to the teeth, running a ubuntu box that provides password protected webserver access to the various components of the vehicle, as well as keeping the 3G connection open all the time. Telemetry built into the RX-8 also keeps track of real time RPM, vehicle speed, coolant temperature, throttle position and even maps current location to Google maps via mash up.
