How is there such big difference between Lexus IS 300 and 350>?

I find it hard to understand what's up with the new (2017-2018) Lexus IS lineup. So they gotten rid of the V6 on the IS 200 and put in a I4T banger which makes 241hp.Here is what I can't understand. The IS 300 with its 3.5L V6 makes 255hp which is 14hp more than the I4T in the 200t, but then we have the IS 350 which is also powered by a 3.5L V6, yet this V6 with same 3.5L (naturally aspirated) makes 306hp, which is 51hp more then the IS 300.Can someone explain this magic? via /r/cars http://ift.tt/2t4k8ao
