The World's Fastest Production Car Was a Jensen Interceptor - Apparently.
In 1966, the Jensen Interceptor, a British sports car, reached a top speed of 141.1 mph (227 km/h). This was achieved by Jensen's chief engineer, Alan Essery, who fine-tuned the car's engine to produce 325 horsepower. The Jensen Interceptor was a relatively unknown model, but its impressive speed made it a notable achievement in automotive history.
