TuningOne of the greatest rewards in owning a car is to modify and customize it to suit your personal taste, and the smallest of changes will have different effects on the behavior of the vehicle. In GT7, players can once again start with a stock vehicle and build their car up gradually to fit their preference, through adjustments made on engine performance, suspension, transmission gearing, brakes, tires, etc.
GT Auto* also makes a comeback with wheel changes, wide body modifications, addition of roll cages as well as other aerodynamic parts. And not to mention engine oil changes and car wash.
Time/Weather Change SimulationsThe time/weather change simulation brought to life in GT7 is unique to Polyphony Digital, who researched the complexities of nature and tailored it into a video game. Referencing a massive amount of meteorological observation data, we have recreated spatial / time of day conditions for particle size distribution and concentration distribution of aerosol particles in the atmosphere on a global environmental scale, in a procedure that is unique to the Gran Turismo series.
The validity of the simulation was checked using Scapes HDR images, for which we have accumulated data for several thousand spots all around the world. As a result, we have succeeded in expressing real and complex skyscapes and changes in light for different times of day and weather.
