Players who download the demo and subsequently purchase the full game will be treated to a custom 2013 SRT Viper GTS, with a rare livery which celebrates the release.
The beefier BX300 steps up to a 2.4GHz Intel Core 2 Duo E6600 CPU, 1TB of storage spanning two 500GB drives, NVIDIA's 256MB GeForce 8600 GTS graphics card, and a 7.1-channel sound card.
With the exception of the Panamera GTS, models with PDK also offer a coasting function in which the clutches open in overrun allowing the engine to idle and the vehicle to coast freely.
