Decreasing the mass of the car.
Reason: Newton's 2nd law gives a = F/m. With the same engine force F, reducing the mass m increases acceleration. Increasing inertia (mass) would do the opposite; "decreasing the reaction force" misunderstands action–reaction (they're equal and can't be reduced to get more thrust), and "increasing the action force" would require changing the engine output.
