* Top speed: This is usually measured on a long, straight track. The current record-holder in this category is often debated and changes, but vehicles like the SSC Tuatara and the Bugatti Chiron have held the title at various times. Verification of these speeds is crucial, as accurate measurement is challenging.
* 0-60 mph acceleration: This measures how quickly a car can accelerate from a standstill. Electric cars often excel in this category.
* Quarter-mile time: This measures the time it takes to travel a quarter-mile (402 meters) from a standstill. Again, electric cars and purpose-built dragsters frequently dominate here.
Therefore, there's no single "fastest car" – it depends on the specific metric you're using. To get a precise answer, you would need to specify which type of speed you're interested in.
