The G35 makes 260 HP and the M3 makes 333 HP. Sounds like HP made a huge difference here. If what you are saying is true, the G35 should walk take the M3. But it doesn't. In fact it loses by a large margin despite the fact the G35 is lighter. There are many factors that affect how fast a car is despite the HP/Torque curve. HP to weight will be much more accurate than a torque to weight curve. If you'ld like I can elaborate quite a bit more on the possibilties, but it's late now. I'd have to get into a discussion on HP vs torque(which I have some very lengthy explanations for) and teh differences in the motors and cars you mention. Consider as food for thought, that you mention 2 turbo cars and in case 1, you compare a FWD car to an AWD car.
You provided an excellent exampleHowever the transmission is different the M3 uses a 6 speed manual while the G35 a 5 speed automatic. The 6 speed G35 runs 14.1.I never said hp is not important. Just TQ makes a bigger difference. A 333tq G35 will be much faster then 13.4sec in the 1/4 mile, but there is no way to find out for sure.
About turbo vs N/A, *turbo lag* the turbo car should be slower, but they both put down the same, a hp is a hp, doesn’t matter how it’s produced,
AWD vs. FWD, more loss to the wheels in the AWD car, so the AWD car is actually in a disadvantage, but has a slight advantage of traction, while the FWD has more hp to the wheels but less tractionthose two things basically cancel each other (not literally) but to compare the two
