Depends on… well, everything, but towing a 1-tonne trailer up a long hill is far more taxing on a car’s cooling system than this. I’d expect any decent car to be designed to handle continuous running at peak torque, if not peak power.
(Why peak torque? Because that’s peak efficiency, for petrol engines at least. Makes sense if you think about it.)
- bluGill 3y agoCars are not built to run at peak torque for long as nobody does that. Cars are design for maximum power for long enough to get up to speed, and which makes for a lot more power at peak torque than they need for running at highway speeds. Sometimes a truck will be designed to run near peak torque while towing uphill on a hot day (AC) with a headwind, but when you do that it takes a long time to accelerate to highway speed and so truckers typically just buy more peak power (trucks are already notorious for slow acceleration). Running at less that peak torque isn't too much a loss (and diesel engines don't suffer nearly as much from running at less than peak torque so the savings doesn't add up very fast for trucks)
- dotancohen 3y agoThis actually sounds like quite the argument for electric trucks.
