Hard wood has relatively high specific strength (Oak wood is 2x steel’s specific strength in kN.m/kg), why we don’t see a lot of wooden car frames and bodies in modern cars?
Wood is cheaper than steel too. Average price for hardwood saw logs is around $35-40 per ton. Steel is far more expensive at over 600 per ton. A car body weights about 1-1.5 ton.
Making a similar strength car out of wood can save a lot of cost compared to steel.
Why wood is not used a lot in car frames and bodies?
If wood is too bulky for road vehicles, what about off road, slow moving vehicles like golf carts and tractors?
