Diesel is a type of fuel, not gas.
It doesnt combust with ignition, but rather with compression. Diesel engines dont have spark plugs like gasoline engines do.
Diesel also has more power density, which means that per amount of volume, it contains more potential power.
Diesel engines provide much more torque then gasoline engines normally do. But it also provides less horsepower than gasoline engines. It is typical to see gasoline engine with a horsepower to torque ratio of about 1:1 or >1:1. The opposite occurs for torque engines. Large semi truck engines can produce around 450 hp while producing over 1000 ft lbs of torque.
The reason that trucks need such torque is because of the loads they carry. High torque is needed to start the pulling of the load.
As for which is faster: Gasoline is much faster for cars and light trucks. Pretty much anything that doesnt require a large load to be hauled.
For heavy trucks and other equipment, diesel would be much faster because a gasoline engine would have a hard time providing enough torque to actually get the vehicle moving.
