I think the manufacturing variable is driveline efficiency, and engine efficiency, since better tolerances will result in less friction loss and more power. But a modern manufacturing line has pretty good repeatability, I wouldn't expect much difference between cars. The machines my company produces are each tested for repeatability and its very good, less than 5% variation, which would be about 10 hp if it were an IS300.

In other words, even if 2 IS300s had the exact same equipment and were built at the same assembly plant, there's a chance that one of them may have a stronger engine than the other.
