Detailed Explanations

SSC Tuatara: The SSC Tuatara is a hypercar designed and manufactured by SSC North America. It features a twin-turbocharged 5.9-liter V8 engine that produces up to 1,750 horsepower on E85 fuel. SSC claimed a top speed of 316.11 mph, but that test was disputed. A later, independently verified run achieved an average top speed of 282.9 mph, making it a leading contender for the fastest street-legal car. The car's aerodynamic design plays a crucial role in achieving such high speeds, and it also incorporates advanced driver assistance systems for improved safety.

Hennessey Venom F5: The Hennessey Venom F5, built by Hennessey Performance Engineering, is designed with the express purpose of breaking the 300 mph barrier. It boasts a twin-turbocharged 6.6-liter V8 engine dubbed "Fury," producing over 1,800 horsepower. Hennessey claims a top speed of 301 mph, but this figure has not been independently verified. The Venom F5 utilizes a lightweight carbon fiber chassis and body, along with sophisticated aerodynamics, to minimize drag and maximize stability at extreme speeds.

Bugatti Chiron Super Sport 300+: The Bugatti Chiron Super Sport 300+ is a special edition of the Chiron, designed to celebrate Bugatti's achievement of breaking the 300 mph barrier. It is powered by a quad-turbocharged 8.0-liter W16 engine producing 1,578 horsepower. Bugatti claims a top speed of 304.773 mph, achieved during a test run in 2019. The Super Sport 300+ features extended bodywork and modified aerodynamics to reduce drag and improve stability at very high speeds. While only 30 were made, they are street legal and thus make the list.

Koenigsegg Jesko Absolut: The Koenigsegg Jesko Absolut is a variant of the Jesko hypercar, specifically designed for extreme low drag and high top speed. It features a twin-turbocharged 5.0-liter V8 engine producing up to 1,600 horsepower on E85 fuel. Koenigsegg estimates that the Jesko Absolut can achieve a top speed of over 300 mph, but this has not yet been independently verified. The car's streamlined bodywork, elongated rear wing, and removal of the standard Jesko's large rear wing contribute to its exceptional aerodynamic efficiency.

Czinger 21C: The Czinger 21C is a hybrid hypercar manufactured by Czinger Vehicles. It is powered by a hybrid powertrain featuring a twin-turbocharged 2.88-liter V8 engine and two electric motors, producing a combined output of 1,250 horsepower. Czinger simulated a top speed of 281 mph. The 21C utilizes 3D-printed components to reduce weight and improve structural rigidity. Its unique tandem seating arrangement places the driver in the center of the car, enhancing the driving experience.

Rimac Nevera: The Rimac Nevera is an all-electric hypercar manufactured by Rimac Automobili. It features a quad-motor powertrain, with each motor independently driving a wheel, producing a combined output of 1,914 horsepower. The Nevera has a top speed of 258 mph, making it one of the fastest electric cars in the world. Its advanced torque vectoring system allows for precise control of each wheel, enhancing handling and stability.

McLaren Speedtail: The McLaren Speedtail is a hybrid hypercar designed for high-speed grand touring. It features a hybrid powertrain combining a twin-turbocharged 4.0-liter V8 engine with an electric motor, producing a combined output of 1,035 horsepower. The Speedtail has a top speed of 250 mph. Its elongated bodywork and central driving position contribute to its aerodynamic efficiency and distinctive design.

Tesla Model S Plaid: The Tesla Model S Plaid is an all-electric sedan that delivers exceptional performance. It features a tri-motor powertrain producing over 1,020 horsepower. The Model S Plaid has a top speed of 200 mph and can accelerate from 0 to 60 mph in under 2 seconds, making it one of the quickest accelerating production cars. Its instant torque delivery and advanced battery technology contribute to its impressive performance.

Dodge Challenger SRT Demon 170: The Dodge Challenger SRT Demon 170 is a drag-oriented muscle car designed for extreme acceleration. It is powered by a supercharged 6.2-liter Hemi V8 engine producing over 1,025 horsepower on E85 fuel. Dodge estimates a top speed of 215+ mph.

Frequently Asked Questions

What makes a car "street legal" in the US? A street-legal car must meet federal safety standards and emissions regulations, and comply with state and local laws regarding lighting, mirrors, and other equipment.

Why are top speeds often "claimed" and not verified? Verifying top speeds requires specialized testing facilities, skilled drivers, and precise measurement equipment. Furthermore, many manufacturers are wary of potential liability issues associated with encouraging drivers to attempt extreme speeds on public roads.

What is the difference between horsepower and torque? Horsepower is a measure of how quickly work can be done, while torque is a measure of rotational force. In simple terms, horsepower determines top speed, while torque determines acceleration.

Are these cars safe to drive at their top speeds? While these cars are engineered for high-speed performance, driving at their top speeds is extremely dangerous and should only be attempted on closed courses with professional drivers and appropriate safety precautions.

How much do these cars typically cost? These cars are typically very expensive, ranging from several hundred thousand dollars to well over a million dollars, reflecting their advanced engineering, limited production numbers, and exclusive status.

What is the importance of aerodynamics in achieving high speeds? Aerodynamics play a crucial role in minimizing drag, which is the force that opposes a car's motion through the air. By reducing drag, a car can achieve higher top speeds and improved fuel efficiency.

What is E85 fuel and why is it used in some of these cars? E85 fuel is a blend of 85% ethanol and 15% gasoline. It has a higher octane rating than regular gasoline, which allows engines to produce more power, but it also has a lower energy density, which can reduce fuel economy.

Conclusion

The title of the fastest street-legal car in the US is a constantly evolving one, driven by relentless innovation and engineering prowess. While the SSC Tuatara currently holds the verified record, other contenders like the Hennessey Venom F5 and Koenigsegg Jesko Absolut are pushing the boundaries even further. Whether powered by traditional combustion engines or cutting-edge electric powertrains, these cars represent the pinnacle of automotive performance and serve as a testament to human ingenuity. Potential buyers should carefully consider their needs and driving style before purchasing any of these vehicles.
