You may have seen this game demoed onstage during the WWDC 2012 keynote, but now CSR Racing is now available in the App Store as a universal app.

Instead of finishing laps faster than your opponents, CSR Racing puts you against other racers on straight tracks. That’s right, this game is all about drag racing. ¬†After (hopefully) getting off to a good start once the light turns green, you’ll be neck and neck with your opponent on the hectic drive to the finish line. Your only hopes of winning are shifting gears at the perfect time.

If that’s not enough to help you, there are plenty of upgrade options available for your car. Choose from turbos, engine stages, ECU tweaks, racing tires and much more to modify your car as you see fit. The customizations don’t just apply to under the hood. You can change your ride’s paint, license plate, and even add custom decals.

Where's Xzibit when you need him?

For the most part, CSR Racing is a freemium title, but don’t let that turn you away. Utilizing its in-app purchases isn’t necessary to fully enjoy the game, which features officially licensed cars from Audi, BMW, Chevrolet, Ford, GM, Mini, and Nissan. The graphics are completely Retina-ready and are honestly pretty stunning compared to other racers available.

You can check it out yourself, as CSR Racing is available for free in the App Store.
