Developer Slightly Mad Studios' World of Speed is a free-to-play massively multiplayer online racing game.
The trailer (below) shows McLaren Automotive's McLaren 12C sports car as it races around a track in Moscow, Russia. The in-game footage of World of Speed is spliced together with real-world footage of the 2013 Moscow City Racing event. World of Speed will launch later this year for Windows PC.
