I sort of agree
my truck is 620hp and will happily pull a loaded trailer up windy hill
now a super car with 700+hp will struggle
so it’s all about big flat torque curves
Exactly. I used to have a 2 litre 500bhp car, in the same village was a huge recovery truck that dragged stricken articulated lorries off the motorway back to their yard, trailer and all. It proudly said on the side it had 500bhp.
Do you think my car would have pulled an articulated lorry with trailer?
Nope.
If you put my car engine in the truck it would hardly pull the tow truck itself around.
At a guess the truck had around 1600ft/lbs of torque, my car had about 400.
Why they advertise truck bhp figures is a bit beyond me as it's largely irrelevant. If the tow truck had said it had 1600ft/lbs of torque I would have been more impressed.
My Benford has a whole 34bhp yet it'll pull itself and a load (5.2 tons) easy enough, it'll set off on tickover in 3rd gear. That's because it produces a lot of torque right from tickover onwards.
