*sighs*... super wala na akong maintindihan dito... wehehehe! pero like what ebbfolls said "Now, say a Toyota 2.0 liter is making 160 HP at 5000 rpm and a Honda 2.0 liter is making 160 HP at 7000 rpm. Both engines are of the same power, thus both are capable of doing the SAME AMOUNT OF WORK, at the SAME AMOUNT OF TIME. (But because their max power figures occur at different engine speeds, both have different TORQUE figures at the rpm where they both make their maximum power. But torque only tells about how strong an engine is without regard for time, while HP tells about how fast an engine can produce results.)"... kahit magkaiba ng max RPM ang isang car kahit pareho ng displacement, both are capable of doing the same amount of work at the amount of time... and the weight of the car also affects acceleration times and top speeds.... hehehe! now im quite enlightened with that answer... Thanks PEEPS! And just as i said... im just TOO curious about car engines... as in tagal ng umiikot sa utak ko ang question na yan... ^_^
