The gas pedal asks the engine for power. Braking turns motion into heat through friction. Watch the piston move up and down and the crankshaft rotate in the corner. Engine speed is simplified and the animation is slowed so you can follow it. Boost cells are arcade power-ups, not a model of a real engine. This is a game, not a driving lesson.
