Who in the US makes fastest cars?

There isn't a single US manufacturer that definitively makes the *fastest* cars across all categories. The title depends heavily on how you define "fastest" (top speed, 0-60 mph time, quarter-mile time, etc.) and the specific models being compared.

However, several US manufacturers are known for producing extremely high-performance vehicles:

* SSC North America: This relatively small manufacturer holds the record for top speed with the Tuatara. While record attempts are sometimes contested, they've claimed speeds exceeding 300mph.

* Rimac (partially US-owned): Although headquartered in Croatia, Rimac has significant US investment and involvement, and its Nevera hypercar competes at the top tier of performance.

* Tesla: While not traditionally known for outright top speed, Tesla's electric vehicles offer blistering acceleration (0-60 mph) and are continually pushing performance boundaries.

* Ford: Ford's Shelby Mustang and other high-performance models are consistently fast and popular, although they might not reach the extreme speeds of hypercars.

* Chevrolet: Chevrolet's Corvette series has a long history of high performance, offering impressive speed and handling for its price point.

In short, the answer to "who makes the fastest cars" is nuanced. While SSC North America currently holds a top speed record, other companies like Rimac, Tesla, Ford, and Chevrolet produce exceptionally fast vehicles in different performance categories.
