Connect your iPad 2 to your HDTV with Apples HDMI Adaptor and the latest update to Real Racing 2 HD allows you race in true 1080p on your HDTV while real time racing telemetry is shown on the iPad 2, It's pretty amazing.
This video is of the replay after the race, I couldn't hold the camera and race :-) but it will give you an idea of what it is like. Enjoy!
