Ok, stick a huge turbo on a 100cc engine and power my 1 ton pickup please. Id like it to feel quick in traffic but also tow a few thousand lbs uphill without really noticing it.

No one buys a 1-ton to feel quick in traffic. A few thousand lbs going uphill can be easily done with a 1/2 ton, and the majority of them are now turbocharged.

Forced Induction has made its way tho. Not all, but a lot of modern turbo engines are great in all three aspects of reliability, performance, and efficiency.

I can see turbo'ed PHEV being the solution to heavy-duty use cases one day. Pretty stoked for the Ramcharger.

People don't buy 1 tons to feel quick. But they want their 1 tons to feel quick.

The examples you gave show that turbos are nice additions to a specific displacement size.

Op said turbos are a replacement for displacement. My example is there to show him they are not.

Does it need to last one trip up this hill or thousands of trips?
