* Top Speed: Currently, the title of fastest production car in terms of top speed is generally attributed to the SSC Tuatara. However, records are often contested and can change.
* 0-60 mph: Many hypercars boast incredibly fast 0-60 mph times, making it difficult to pinpoint a single "fastest" in this category. The top contenders change frequently as new models are released.
Therefore, there isn't one single answer to who makes the *fastest* car. The contenders shift as technology advances and new cars are produced and tested. You would need to specify *which* kind of speed you're interested in (top speed, 0-60 mph, quarter mile, etc.) to get a more precise answer at any given time.
