hp,bhp,torque- why so less or so much more? Just read the news article "Mahindra launches Arjun Novo 65 and & 75HP tractors" and another a few days ago about Tata launching a new line of trucks.
Tractors are considered to be workhorses and logically should have more muscle and power, yet the specs read 65 or 75 HP. The tata trucks had 138 - 177bhp and 360-590 nNm torque it says.
Most medium and large cars carry much larger numbers- my Octavia TSi says 180bhp, the BMW 3GT 330i is 252 bhp.
Can someone educate me, and others like me, about what exactly these numbers mean - hp,bhp, torque etc? Why is it that a tractor or a truck , something that really needs grunt seems to have such low numbers while a much lighter sedan that really seems to do much less "work" have higher numbers?
A kind of "idiot's guide to power specs".
