Or there is less drivetrain loss that 20%. Remember, all the manufacturers are trying to get as much fuel economy as they can out of cars. They aren't getting gains by just making the engine more efficient. The whole point of the 707 HP thing was so they could have bragging rights. If it made 750 HP then they would have advertised that.
