Need for Speed: Carbon features a new car customization option called "Autosculpt", enabling players to utilize aftermarket car parts and shape/mould the parts to their liking. Players can also have multiple customed vinyls as well. Performance tuning has been redone so that players, as upgrades are purchased, can tune the car for a number of different properties, such as higher top speed or higher acceleration. Unlike Most Wanted, all of Carbon's performance tuning/enhancing and car customizing is done inside the safe house.
