With this particular Grid 2 pre-order bonus being one of the more intriguing ones on offer, it's pleasing to know that Codemasters has finally revealed the final details we (until now) didn't know about the IndyCar Pack.
On top of the Dallara IndyCar and the oval track at the Indianapolis Motor Speedway, the IndyCar Pack also comes with a batch of four Pace Car' liveries that can be used during online multiplayer races.
However, these liveries aren't available for every car on offer in the game: the quartet of Pace Car decals are evenly split between the Chevrolet Camaro SS and the Chevrolet Corvette Z06 Centennial Edition.
Given both of those cars have been Indy 500 Pace Cars in real life, it is befitting that the Camaro and the 'Vette are the only two cars that can be given this unique treatment.
As Codemasters revealed a short while ago, everyone who wasn't able to acquire the IndyCar Pack bonus when they pre-ordered Grid 2 will be able to purchase the pack from the Xbox Live Marketplace, the PlayStation Store and Steam from the day the game officially goes on sale in their region.
