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.
In: Engineering
All of the energy from a car’s engine becomes heat, eventually. Some of it just takes a detour to push the vehicle.
The difference between a lambo and a civic is going to be mainly in the engine itself. The tiny engine in the civic can’t produce nearly as much power, but also has way less stuff moving around in it and less friction. The lamborghini’s huge engine wastes a ton of energy.
Another difference is aerodynamics, but between the two cars you mentioned at that speed the engines themselves are going to be the main difference.
