This is the iPhone controlled Mercedes SLS that enables a smartphone's personal soundtrack to accompany luxury grand tours. A free app allows you to drive the Mercedes up to 30' away via Bluetooth while music plays through the iPhone; when the car is stopped, its gulf wing doors open and music is streamed to the car's onboard speakers. The Mercedes can move and flash its lights in tempo with the music for fully synchronized joyrides. Motion-sensing accelerometers in an iPhone allow drivers to accelerate forward or backward and turn the car with simple tilts and pans of the smartphone. The app displays the authentic Mercedes SLS dashboard and steering wheel. Drivers can illuminate the car's turn signals, brake lights, headlamps, and interior light. Compatible with iPhone 5, iPhone 4S/4/3GS; iPad 3/2; and iPod 4th/3rd generation. Requires iOS 5. Includes four AA batteries. 10" L x 4 3/4" W 3" H. (2 lbs.)
