Sony has released the free PlayStation 3 Gran Turismo HD Concept demo a day early, and based on this report over at Kotaku, I'd suggest you download the demo as soon as you possibly can, because come Christmas there are going to be quite a few more people hitting Sony's online service. The demo weighs in at 625mb and should include the following features;
"Upon downloading Gran Turismo HD Concept, PS3 users have access to the Eiger Nordwand course and can compete in Time Trial races to collect and unlock new cars. Upon unlocking the initial 10 cars, the player has access to 10 more "Tuned Cars," as well as access to a new driving mode called "Drift Trial."
In the "Drift Trial" mode, the player can master the art of drifting and achieve ultimate control of their car. Furthermore, when connected to the PLAYSTATION®Network (PS Network), the player can upload their times and view the Top 10 rankings for each car and mode, as well as play and save replays online.

Additional Information About The Game Modes in Gran Turismo HD Concept
In "Time Trial" mode, the player selects a car and must complete the Eiger Nordwand course within the target time indicated at the top of the screen. Each time the player beats the target time, a new car is unlocked and made available for selection. As stated, upon unlocking all of the cars, the player can access tuned cars, along with the option to race Eiger Nordwand in the opposite direction.
In "Drift Trial" mode, the players drifting technique is tested, rather than their lap time. The player earns drift points based on their drift angles, racing lines, and speeds within evaluation zones located at various turns on the course. For each evaluation zone, the results are based on the number of flags and a numerical figure. The point total from all zones determines the players drift points for the lap and is counted toward the rankings.
The following settings are available during gameplay: 1) Transmission the player can select either Manual or Automatic. 2) Stability Management (SM) the player can turn this ON or OFF during gameplay. ASM is designed to prevent vehicle skidding by controlling each of the four wheel brakes independently. 3) Traction Control (TC) Level the player can set the TCS level, which senses drive-wheel slip and prevents wheel spin. 4) Tires the player can select front and rear tires from nine types of brands." - Sony press release
