What is strength to weight ratio in cars?
But a car’s power to weight ratio is the amount of power a vehicle has relative to its weight. Translation – divide the horsepower of the engine by the weight of the car and that’s your power to weight ratio. For example – the Dodge Viper has a 450 hp engine to accelerate 3,320 lbs.
Does car weight affect HP?
The “horsepower” is just a measure of the amount of power the engine is capable of producing, which is independent of the weight.

The same applies for an automobile. To break it down in quarter-mile drag racing, every 100 lb removed from a vehicle equals [approx.] 1/10th of a second improvement.
How much HP does removing weight add?
With calculations complete, final numbers show a horsepower to weight ratio of 18.18. For every 18.18 lb removed, the car will gain approximately one horsepower. The same properties apply for the torque figures as 1 lb-ft of torque is gained for every 22.04 lb removed from the vehicle.
Does making your car lighter make it faster?
The amount of energy it takes to move a car from one point to another is highly dependent on the mass, so the lighter the vehicle, the less energy it takes to move it from one place to another. A lighter car is also a faster car.
