A lot of it comes down to learning how to drive the new car. When I went from a 350 to an s2000 I had the same concerns.
The 350s v6 allows you to become a lazy driver, there is always power and torque in most gears at most speeds, if I try and accelerate from lower speeds in 4/5/6th gear in the honda it's pretty unimpressive. The 350 on the other hand, did it with relative ease
