What is the fastest car in GTA Online?

The title of the fastest car in GTA Online frequently changes as new vehicles and updates are introduced to the game. As of the latest update, the Ocelot Pariah is considered one of the fastest cars in GTA Online in terms of top speed. When properly upgraded, this sportscar can reach impressive speeds, outpacing many other vehicles in straight-line races. However, it's worth noting that while top speed is a crucial factor for determining the "fastest" car, other elements such as acceleration, handling, and traction can significantly affect performance during races with varied terrain or numerous turns. Players often consider these factors to determine the best car for their particular racing style or for certain types of races within the game.
