Diesel engines are more efficient than gasoline engines - Peter Bell

Diesel by its very nature contains 20% more energy in a gallon of fuel than a gallon of gasoline. Combine this with the diesel engine's higher compression ratio and therefore efficiency...

VW Jetta

...it is not hard to see why vehicles like the VW Jetta TDI get 40+ miles per gallon on the highway, compared to the US fleet average of 23mpg.

If you look at the commercial fleet, it is all diesel and the reason for this preference for diesel engines is that commerce demands the most fuel efficient way to move from point A to B. If businesses don't think this way their competitors will and those competitors will enjoy the higher profits or larger market share that a more efficient operation enables you to obtain.  

Fuel efficient vehicles don't look very appealing

Some people might argue that fuel efficient vehicles are not available or are not very appealing vehicles to buy, but they forget about the diesel engine.

The Touareg - this vehicle has a lot of power.

Jeep Liberty 2004Chrysler has launched their Liberty with a diesel engine approved for B5 biodiesel right out of the factory...

VW have the Touareg...

 


Mercedes Benz - E320If you are looking for some performance, the new 2008 Mercedes-Benz E320 can zoom from 0 to 60mph in 6.8 seconds with only a 3.2L engine and yet still return 37mpg. That is 10mpg better than the same vehicle powered by a gasoline engine.

BMW 530dThe BMW 530d goes from 0-60mph in 7 seconds, yet still gets over 40 miles per gallon in average fuel consumption.

The same car powered by a gasoline engine only manages to get 23 miles per gallon.

The interesting thing about the diesel engine is that a large number of the vehicles made in the the world today have a diesel engine option. The annoying thing is that these diesel options are not made available in the USA, due in a large part to the general lack of interest in fuel efficiency in the US while fuel remains relatively cheap compared to highly taxed European fuels. 

What is the auto industry capable of producing?

VW Ein Liter (1 liter) Auto

Opel Eco-Speedster If you want to go really fast and yet still be miserly on your fuel use, how about the Opel Eco-Speedster sports car prototype. The 1.3-litre Ecotec Diesel engine produces 112 hp, giving the car a maximum speed of over 155 mph and fuel consumption of 94 mpg.

The 2001 VW Ein Liter Auto demonstration car achieved a stunning 230 miles per gallon and is quite capable of cruising at over 70 miles per hour.US Marine Corp Diesel Powered Motor Cycle

If you are a motor cycle fan, but want to use Biodiesel in a motor cycle, what is available? http://dieselmotorcycles.com make a motor cycle for the US Army and US Marines, click the link for a bigger picture of the Marines version.

Diesel engines are not as clean burring as gasoline engines

The mandating of Ultra Low Sulfur (15 ppm) specifications for all on-road US diesel in October of 2006 enabled all the European engines to become available on the US market. This reduction in the sulfur content of US diesel enables all the clean diesel technology available in the European market to now come to the US market. The adoption of this clean diesel technology means that diesel engines can be as emission efficient as gasoline engines.
