Highly-anticipated PS3 racer Gran Turismo 5 has been pegged to be costing developer Polyphony Digital $60 million, making it one of the most expensive videogame productions to date.

Polyphony Digital CEO Kazunori Yamauchi explained to Autoweek just where the investment had been made: “There will be 400,000 polygons per car, 100 times more than were present on GT4. GT4 had 4,000 polygons per car.”

The game also features 20 different environments and 70 racetracks. Cars will now receive crash damage. Last week, Gameplanet’s unscrupulous rumour-mill department also speculated on the possibility of a track editor.

The game is due out in Japan in March, with a western release “probably” due shortly thereafter.
