There is a lot of debate and controversy about gas and diesel engines. Let's take a look at some key points of both.

Diesel

Less expensive to run
Not as powerful
Offer more torque
Vehicles powered by diesel more expensive.
Vehicles are more reliable because less complicated internally.
Vehicles are heavier to build.
Vehicles normally last longer.
Generally less expensive.
Will normally last longer in terms of miles.
Engines are generally loud.
Emits black smoke when engine is throttled.
Fuel is dirtier.
Turbo charged diesel will match standard gas engine in terms of power.

Gas

Produce more horsepower
Gas engines are more tunable than diesel.
Can get better power increases.
Less expensive in terms of producing power.
Parts are a lot less expensive.
Engine doesn't last as long as a diesel because it is less complicated and less heavy internally.
Fuel is usually more expensive.
Fuel burns cleaner.

Diesel is often thought of as smelly and noisy. Many think that the only place for diesel is in a tractor or a semi, there are many other vehicles that are diesel powered however. Each person must determine what their individual needs are. A person has to do their research before making a purchase of any kind, but especially a large purchase such as a vehicle. You do not want to spend thousands of dollars just to realize later that you made the wrong decision, so take your time and do your research to help you make the best decision for you.

One question that isn't answered here is the emission standards with the black smoke that comes from the diesel engine. The reader is left to wonder if the emission standards are fine or if they are high due to the dirtier burn of diesel. This would be worth investigating. It should also be investigated if noise pollution is a factor with these engines.

When choosing which type of vehicle is what you want you must first determine what your needs are. If what you want is power and tuning options then a gasoline engine is what you are looking for. But if it is power and torque (a force that produces or tends to produce a twisting or turning motion, so in this instance the turning of parts of the motor) that you are looking for then you need a vehicle with a diesel engine. There are certainly plenty of choices out there. Just be sure that you are checking on what your needs are and you will be certain to have the right vehicle for you. Make certain that the vehicle will match your needs and give you the performance necessary to do the job.
