Most Semi tractors use large displacement in-line 6 cylinder turbo diesels engines. Depending on the engine model newer model trucks average 300-500 horsepower and between 1,250-1,750 lb. ft of torque.

semi trucks have different motors for what the truck is designed to do. they typically can have anywhere from 300 all the way up to 600+ and are 99.9% diesels. they come in inline 6's V8's and some 12 cylinder motors. some are turbo charged, twin turbo charged or if its an old detroit it could be a 2 stroke twin turbo supercharged diesel. generally the motors are made from a few big engine companys, CAT, Cummins, and Detroit. These engines are used by truck companies like Peterbilt, Western-star, Kenworth and International.
Some truck companies like MACK make theyre own engines.
The torque output is much more then the hp. one peterbilt semi i worked on had a Cat 425 engine in it. it made 425hp and 1500Ft/LBS or torque!

i know quite a few semis have twin turbo supercharged engines. At least the engine in the semi that delivered to my business had. The driver claimed around 1700lbs of torque, but I don't know for sure.

I remember a steam powered tractor on a farm near my home in the fifties, also steam powered road rollers and asphalt boilers. There are quite a few traction engine rallies at this time of year up and down the country, there are many of these wonderful vehicles on show there !

I think the steam powered tractors were all retired in the 1940s. I have seen a few back then, but they were just on display. Gas tractors came on strong in the 1930s and put the steam guys out of business.

Big diesels with gobs of torque for the pulling of heavy loads. Many engines are out there on the highway, including Cats, Cummins, Detroit, cubic inches are usually around 500-700 and horsepower runs from 325 to 600 with torque from 500-900 ft pounds. Cylinders are sixes and eights.
