Calculating Automotive Engine Power: Load Capacity vs Dry Weight

AI Thread Summary
When calculating automotive engine power, the total weight of the vehicle, including load capacity, should be considered for accurate performance assessment. The dry weight of the vehicle alone does not account for the additional load that affects engine power. It is essential to include the weight of any cargo, such as bricks in a lorry, as this impacts the vehicle's performance. The discussion emphasizes the importance of using the laden weight for power calculations to reflect real-world conditions. Accurate calculations require considering all contributing weights to determine engine effectiveness.

Well if the vehicle is laden, take the weight of everything there. If your lorry is full of bricks, they'll have an effect on its performance.

How are you using weight to calculate power?
