The Real Life Car/Location Names mod for Grand Theft Auto 5 modifies the in-game vehicle and location names to reflect their real-world counterparts. This modifies the entire in-game names of vehicles to match their real-life equivalents, making the game more realistic. For instance, instead of the in-game car brand "Pfister", it will be changed to "Porsche". 

Moreover, all the in-game street names, locales, and districts are renamed to their actual names in Los Angeles, California. For instance, "Vinewood" becomes "Hollywood", "Los Santos" becomes "Los Angeles", and so on. This provides a more authentic and immersive gaming experience for players who are familiar with the real-life geography and car models. 

Given the wide range of vehicles in Grand Theft Auto V, this mod affects numerous vehicles, each with their unique specifications pertaining to power, speed, torque, and more, as defined in the game. The exact specifications for each vehicle would depend on the real-life model it represents. For instance, the speeds and torque for a sports car would be much higher than a standard city vehicle. 

Please note that this mod does not change the physical appearance, performance, or handling of the vehicles or the physical structure or layout of the locations - it purely changes the names to reflect reality. This mod also does not add any new vehicles or locations to the game.
