Gran Turismo 5 Prologue is due for release in 2008. GT TV will also feature news and features about the motoring world.
"We're sure that players will be as thrilled as we are when they get the chance to put their own driving skills to the test on the Top Gear Test Track in GT5, as well as enjoying classic episodes of Top Gear via GT TV," said Kazunori Yamauchi, president of the game's developers Polyphony Digital, in a statement.
