Sony's fifth entry in its flagship racing series includes over one thousand licensed cars that, for the first time in the franchise, will show real-time damage based on the point of impact and rate of speed. Other visual enhancements include smoke from tires, sparks from rollovers, and the gradual accumulation of dirt. The vehicle physics engine introduced in Gran Turismo 5 Prologue has been replaced with a revamped model to offer more realism. Play modes include the GT Career Mode, Championship Races, Arcade Mode, and License Tests, with a progression system that lets you earn credits to further customize your ride(s).

The career option features a world map that lets you enter races, visit licensed dealerships, browse various tuning and body shops, and view nearby car washes to return your vehicle to its showroom state. More than 20 tracks are included, each supporting over 70 variations to offer new twists and turns each time you play. Snap photos of your best races from multiple angles and store them in an album, or capture replay footage to share with others on YouTube. Four players can compete via split-screen display, and up to 16 can battle each other online via PlayStation Network. Online features include public and private lobbies as well as text and voice chat. Owners of the PSP version and/or Gran Turismo 5 Prologue can also transfer unlocked vehicles to the PS3 game's garage.

The collector's edition of Gran Turismo 5 includes several notable items in addition to the game. Headlining the set is an exclusive diecast model of the 2009 Nissan GT-R Spec V with custom Gran Turismo livery. The 1:43 scale replica is produced by collectible car maker Kyosho. Also included is a 300-page "car lover's guide" written by staff at Polyphony Digital, the game's developer. The book covers driving techniques, the history of the automobile, game reference material, and more. Rounding out the list of extras are a custom-etched keychain, a voucher for five downloadable cars, a numbered certificate of authenticity, and custom packaging. ~ Scott Alan Marriott, All Game Guide
