Detailed Explanations
ThrustSSC: The ThrustSSC is a British jet-propelled car that holds the current land speed record, achieved in 1997. Powered by two Rolls-Royce Spey turbofan engines, the same used in fighter jets, it reached a speed of 763 mph (1,228 km/h), becoming the first land vehicle to officially break the sound barrier. Its supersonic capability and groundbreaking engineering solidified its place in history.
Bloodhound LSR: The Bloodhound LSR (Land Speed Record) project aimed to break the existing land speed record and potentially exceed 1,000 mph. It was powered by a Rolls-Royce EJ200 jet engine, supplemented by a Nammo hybrid rocket. While testing showed promise and exceeding 600 mph, the project faced financial difficulties and is currently stalled, leaving its full potential unrealized.
North American Eagle Project: The North American Eagle Project was another ambitious attempt to break the land speed record, utilizing the fuselage of a Lockheed F-104 Starfighter. Powered by a General Electric J79 turbojet engine, it aimed to reach speeds exceeding 500 mph. Tragically, the project ended after a high-speed crash in 2019 resulted in the death of the driver, Jessi Combs.
Spirit of Australia: While not technically a car, the Spirit of Australia is included to highlight the pursuit of speed on water. This jet-powered boat holds the current water speed record, set in 1978 by Ken Warby. It achieved a speed of over 340 mph (555 km/h), demonstrating the incredible forces involved in hydrodynamics at extreme velocities.
Hennessey Venom F5 Revolution: The Hennessey Venom F5 Revolution is a track-focused variant of the Venom F5 hypercar. It features significant aerodynamic enhancements, including a large rear wing, front splitter, and dive planes, designed to generate substantial downforce. While its top speed is estimated to be around 300+ mph, its primary focus is on achieving blistering lap times on race tracks.
Koenigsegg Jesko Absolut: The Koenigsegg Jesko Absolut is designed to be the fastest Koenigsegg ever built. Its incredibly low drag coefficient, achieved through its elongated "long-tail" design and removal of the large rear wing, allows it to theoretically reach speeds exceeding 330 mph. Powered by a twin-turbo V8 engine producing up to 1600 horsepower on E85 fuel, it represents the pinnacle of aerodynamic efficiency and power.

Frequently Asked Questions
What makes a car "not street-legal?" Cars are deemed not street-legal if they don't meet safety and emissions regulations for public roads, often due to extreme modifications or specialized designs.
Why aren't these cars street-legal? These cars often lack features required for road use, such as headlights, turn signals, and proper crash protection, or they exceed noise and emissions limits.
What is the land speed record? The land speed record is the highest speed officially recorded for a land vehicle, currently held by the ThrustSSC at 763 mph.
What kind of engine does the ThrustSSC use? The ThrustSSC uses two Rolls-Royce Spey turbofan engines, the same type used in fighter jets.
Where are these non-street legal cars typically used? These cars are typically used on race tracks, drag strips, or dedicated speed trial courses.
