Punctually at midnight of April 30, 1978, the five pistons in the diesel engine of the Mercedes-Benz C 111-III began to work, supported by an intercooled exhaust gas turbocharger which, at 130,000 revolutions per minute, pressed enough air into the combustion chambers to boost the output to 230 hp. That was more than enough power for accelerating the Mercedes-Benz in record-hunting trim to a top speed of around 325 kilometers per hour. Because of its very “long” ratio, the car did take its time, however – a complete 12.66 kilometer lap of the circuit in Nardo in southern Italy, to be precise - to reach this speed.

Yeah, I don't think it will go 1000000 miles much less than 10K I bet.
kinda hard to warranty that sucker!
