But anywhere where higher HP cars can stretch their legs, they'll easily show their strength ... outright acceleration at speed ... and you'll be left in the dust. Power rules because drag increase as the cube of speed. 200HP just doesn't go that far countering drag forces. Take these two easy examples....
Say, for the FRS/BRZ if 3HP is needed at 30mph, then 24HP is required at 60mph, but 192HP is needed at 120mph. It's pretty much finished accelerating.
vs. let's take a 350HP Mustang
if 4HP is needed at 30mph, then 32HP is required at 60mph, but only 256HP is needed at 120mph. There's more HP left and it will contiune to accelerate just fine.
Long story short, this car will rock on the twisties, you'll be crying on the long straights.

lol you know you need about 9-15 hp to go 60mph depending on your drag ratio
EDIT: plus overcoming rolling resitance, forgot about that :P so its anywhere between 19-24 hp but not 32 hp and you dont need 192 hp at 120mph its about 120hp...
these are the calculations for a 6 series with a .29 CG, remember the 86 has a lower .27 CG weighs less and is a smaller car, has skinnier tires and less rolling resistance....
