The 1000-horsepower, 2381-pound Lotec Mercedes-Benz C1000 was commissioned as a one-off by a UAE businessman at a cost of $3.5 million. A twin-turbo 5.6 liter Mercedes-Benz V8 pushes the car through a Hewland 6-speed transmission to a claimed top speed of 268 MPH. And is even today faster than the original Bugatti Veyron. source
