The future of the diesel car

2010 VW super efficient diesel gets over 200 MPG

If you’re wondering why I began with diesels, it was the simple fact that I have a lot of experience with them.  After I had such good experience with my 1999 Volkswagen beetle, my wife and I purchased a 2002 Volkswagen Jetta TDI with an automatic and just recently we purchased a 1999 Volkswagen Jetta TDI with a standard transmission for my stepdaughter.

The second reason that I chose to speak about diesels first is because diesel engines are superior to gasoline engines in many ways. They have fewer moving parts and are much more efficient than gasoline engines. Diesel engines are also built with sturdier parts to withstand higher compression pistons that are used in the engine design. These facts enable the average diesel engine to last much longer than an average gasoline engine. Volkswagen’s diesel engine longevity is legendary.  Some members of the TDI club have over 500,000 miles on their engines.

According to Wikipedia “Diesel-powered cars generally have a better fuel economy than equivalent gasoline engines and produce less greenhouse gas emission. Their greater economy is due to the higher energy per-liter content of diesel fuel and the intrinsic efficiency of the diesel engine. While petrodiesel’s 15% higher density results in 15% higher greenhouse gas emissions per liter compared to gasoline,[6] the 20–40% better fuel economy achieved by modern diesel-engine automobiles offsets the higher-per-liter emissions of greenhouse gases, and produces 10-20 percent less GHG emissions than comparable gasoline vehicles. Biodiesel-powered diesel engines offer substantially improved emission reductions compared to petro-diesel or gasoline-powered engines, while retaining most of the fuel economy advantages over conventional gasoline-powered automobiles.”

In addition to greater efficiency, back in 2002, Volkswagen created an experimental car that got over 285 MPG. Volkswagen was shooting for the car to go 100 kilometers on one liter of diesel.   When tested however, it only took .89 liters to go 100 kilometers (or around 285 MPG).  Here’s the math:

3.78541178 liters is equal to one gallon, to go 100 kilometers and one kilometer equals 0.621371192 miles, 100KM would equal 62.1371192 miles (or 235.22 MPG).

Remember, this concept car was developed in way back in 2002 and it actually got better fuel economy, than anticipated scoring a sweet .89L/100km in VW testing or closer to 285 MPG. The production car due in 2010 is supposed to get more like the 235 MPG number.  I don’t know about you but I’d like to have one of those to go to works or just cruise around.
