EA has announced that a free demo of Need for Speed ProStreet is now available at the Xbox LIVE Marketplace. The demo allows players to test out the BMW M3 E92 and the Nissan GT-R Proto in two events: Speed challenge on the Nevada Highway and a Grip challenge on the A-43 interloop.

In addition, the Blueprint Demo, a new feature available now on the Need for Street ProStreet official site, allows you to start your career early and develop your ultimate ride. After selecting a vehicle, you can make modifications to tune the performance of your car. Then, save your Blueprint to your EA account and bring it up as often as you want to keep tuning for your ultimate ride. Once you are happy with your Blueprint, “Submit” it to your Gamertag or PS3 ID and bring it up when you’re playing the game to test out your tuned car.

Need for Speed ProStreet is Need for Speed like you’ve never experienced before, packed with the visceral emotions and power that defines authentic street racing.
