10 Non-Truck Vehicles in the U.S. Available With a Diesel Engine

Most vehicles come equipped with standard internal combustion gas engines. However, there are increasingly more models that now offer diesel engines, too. Diesel is often considered more efficient than traditional gas, mainly for those not engaging in city driving. Vehicles powered by diesel will have more torque to offer and achieve better fuel economy with impressive acceleration. 

The science is the key difference between gas and diesel. Fuel and compressed air combine with piston pressure in a traditional gas engine. The spark plugs then ignite. In any diesel engine, the air is compressed first, making it hot before the fuel hits it, causing the ignition. This translates to an almost 20% fuel efficiency advantage over gas engines.
