Need for Speed Rivals adds Koenigsegg One:1, 'the fastest car ever built,' for free

The Koenigsegg Agera One:1 is debuting at the Geneva Auto Show today, and may be "the fastest car ever built." With a one-to-one ratio of weight and horsepower, the One:1 produces 1340 horsepower while weighing just 1340kg. Only six of these $2 million cars will be manufactured--and they're already all sold out.

So, how else will you be able to get your hands on this ridiculous car? In Need for Speed Rivals.

A title update for Xbox One, Xbox 360, PS4, PS3, and PC will add the car for free. For car nuts, this is reason enough to jump back into EA's racing game.
