I've heard before that a 245 horsepower motor will find its way into the GS300. I wonder if that motor will find it's way into the IS300. With 245 horsepower, that car should pull 0-60 times into the mid 6 range (for the auto) and maybe lower 6 range or upper 5 range with the manual transmission. I forsee this engine replacement as a possibility if Audi has high output 6's and possibly V8's in their A4's. 245 hp would make the IS300 even more competitive with the 330i BMW.
