So let’s assume we have two cars. One is a really eco-friendly family car sedan, and the other one is a lamborghini. Both drive at a speed of 100kmh (62mph), And lets say we load up the lighter of the cars with some weights, so that they weigh the same. So lambo would on average, consume more fuel.
My question is, where does this extra power vanish to? Since fuel makes an explosion and explosion drives the torque of the car, where does this explosion power vanish to in a lambo? Since it generates more explosion, but still drives at the same speed.
