One thing that I've been trying to understand better is why trucks can pull so well with 400-600 hp while many supercars and hypercars with 600+ hp can't even tow another car without choking. I know transmission and chassis tuning, among other things, are crucial elements in towing capacity, but since power is torque times speed, why does a truck engine need to weigh as much as several cars and have massive displacement in order to pull cargo even though it outputs less power than a supercar engine?
If I were a truck driver, I definitely think I'd prefer the roomier cabins of front-engined trucks, but modern European trucks are cab-overs and are often quite safe, comfortable, and fuel-efficient. Volvo and Scania in particular excel in all of these areas, according to reviews I've seen.
Of course, there's also the extra maneuverability that comes from having a shorter wheelbase, although I'm not sure how important that is to a skilled driver.
You should have used a spoiler on these. Pornographic content is banned by Rule 5.
I didn't see anything pornographic in the pix I posted.
If there is, it's by accident.
Edit....
I realized you're joking.
Truck engines are designed to run at max power
for a much longer duty cycle than cars. And they
have the weight & gearing to use it for heavy pulling.
High performance cars are lightweight & their engines
aren't designed for continuous max power output.
I recall that in the 70s, Ford designed 1st gear in
cars to only last an hour at full power. That was
more than would be used in hundreds of thousands
of miles.
Cab-over trucks are less safe because there's less
crush volume in front of the driver. European trucks
typically negotiate more cramped conditions. Perhaps
there are length limitations too...which would be bad law.
For long life, engines weigh more because they have
heavier duty components. And diesels run at far
higher compression ratios. Stationary engines weigh
even more. The 12 hp Graz I just removed weighs
around 8000#. The flywheel alone is about half.
Some low speed oil field engines have been run
continuously for 100 years. Operators just keep
replacing ignition parts (torch heated hot tubes).
Their power/weight ratio is far lower than heavy
truck engines.
