F1rpm.com is a free online game in beta
You control a racing team against players from all over the world. Working from your virtual office you are able to design, repair and setup your racecar, forge deals with suppliers and sponsors, give tactical orders to your driver and decide on race strategies.
The game is in active development so expect some time until you can enter. If you manage to enter, you will be part of the development process, acting not only as a player, but also as a tester.
