Like what SW03ES said "If power and a manual is extremely important to you, you're not the buyer Lexus is targeting with this car."
The new Is. has much to afford than just that. If your looking in just horsepower, try focusing on american cars. All their cars are all pure power. !Removed! are turbo/supercharge.
And for those ppl that compare Is. with other cars like S4, M3, STi. You guys are totally comparing the wrong car with the Is. First you look into the price range. So TL, G35, IS, 330, etc. all those come into mind when comparing.
