Power-to-weight
Power-to-Weight Ratio (hp/t)
In one sentence:
Engine horsepower divided by vehicle weight — the main driver of acceleration.
What it means
Power-to-weight ratio, measured in horsepower per tonne, is the best single indicator of how quickly a tank accelerates and climbs. Light tanks run 20+ hp/t, mediums typically 12-18, and heavies can dip below 10 — which is why they take an eternity to reach positions.
How it's calculated
Power-to-weight = engine power (hp) ÷ combat weight (t)
Example
A 45-tonne medium with a 900 hp engine (20 hp/t) will out-accelerate a 60-tonne heavy with a 750 hp engine (12.5 hp/t) even though their top speeds look similar on paper.
Why it matters
Acceleration wins races to key positions in the first minute and lets you disengage from collapsing flanks. Top speed is a cap; power-to-weight is what gets you there.
Common pitfall
⚠ Ignoring terrain resistance — two tanks with equal hp/t can still differ sharply in real acceleration on soft ground.
