Question: which is faster a zr1 or z06?
Answer: The ZR1 doesn't hit its 687-hp peak until 6500 rpm whereas the Z06 maxes out at 584 horsepower at 5600 rpm and then holds steady over the last 900 revs. Both engines produce a huge mesa of usable torque at relatively low engine speeds, but the ZR1's tilts ever so slightly upward until 4900 rpm.
