Help me clarify two concepts about torque and horsepower
I've been thinking about two concepts but I need someone to clarify them for me:
1) Assuming we have two identical cars in every way with one making say 250hp at 6000 rpm and one making 600hp or 250hp at 2000 rpm.
If the first car were to shift at 6k rpm and the second at 2k rpm, would they be equally as quick in accelerating? Top speed would be higher for the first car unless the second one has taller gear ratios correct?
2) Assuming a car's engine turns at 2000 rpm driving at 100 kph with say a **** load of torque and suddenly the car climbs up an incline with cruise control.
Would it automatically increase the speed of the engine if it does not downshift from the extra load or will the large amounts of torque keep it cruising at 100 kph at 2000 rpm?
Thanks!
