Gas vs Diesel: What’s the Difference?

As more and more auto manufacturers are offering diesel models, many customers have been asking themselves which is the better choice. In this blog we give you some insight on the differences between gas and diesel.

How Engines Work

Both gas and diesel engines use internal combustion. Air enters the engine and combines with fuel. The engine’s cylinders compress that mixture, which ignites and then triggers the motion of the piston and crankshaft. The crankshaft then activates the vehicle’s transmission and tells it to turn the wheels of the car. Afterwards, the piston moves back to its original position to expel the spent gas from the engine through the tailpipe as exhaust. This process seems lengthy, though it’s quite a short and rapid process which occurs multiple times every second.

The only thing that differs between gas and diesel engines is the ignition process. A gasoline engine requires an electric coil, distributor, and an alternator in order to be functional. On the other hand, a diesel engine has no need for any electric system–except when it needs battery power to start up.

What’s the Difference?

Most vehicles today run either on gas or diesel, but not many know the differences between the two fuels. Gas engines are a lot less noisy and the exhaust fumes that come from them are a lot less polluting. On the other hand, diesel fuel gives you better gas mileage and a lot more torque which is ideal for larger vehicles.

The major difference between the two fuels is the way in which the two are burned in an engine. Cars that consume gas use spark plugs to ignite the fuel on account of the low compression ratio of the engine. Alternately, cars that consume diesel have a higher compression ratio and therefore generate enough heat. Because of this spark plugs aren’t needed to ignite the air and fuel mixture present in the engine.

Makes & Models

Diesel-powered cars are making a comeback. Consumers are demanding vehicles with robust engines and better fuel economy–meaning diesel is worth considering. Here are some of the best diesel-powered vehicles to fit a range of budgets and needs.

  • Chevy Colorado – $37,700+
  • Jeep Wrangler – $39,300+
  • GMC Sierra 1500 – $40,400+
  • Ford F-150 – $42,500+
  • Chevy Suburban – $50,300+
  • Land Rover Discovery – $54,300+
  • Land Rover Sport – $69,5000+

The gasoline versus diesel debate is a very old one, and both fuels have their pros and cons. However, the consensus is that for city driving a gasoline is the way to go, while a diesel-powered vehicle is just right for the long haul-heavy duty stuff.
