Big, smoke belching 18 wheelers and heavy duty
trucks? Yes. Cars? No! At least not yet, but wait … there’s
more, much more automotive retailers need to know about what their
showrooms will sell and their service areas will repair and service in the
near future.

So, what’s the big deal
about diesels?
Perhaps surprisingly to some, diesel engines,
while invented and patented in 1892 by Rudolf Diesel, were not used in
passenger vehicles until 1936 when Mercedes-Benz introduced the 260D, the
world’s first production diesel car. Until then, diesel engines
– which were big, bulky and difficult to start in cold weather
– were used in heavy trucks, steamships, freighters and similar
equipment.
After the war, technological improvements and
innovations were added to the diesel by Mercedes and in the 1970’s
large volume production of diesel-powered passenger cars commenced. Today,
more than 50 percent of all vehicles sold in
Basic question: what makes a
diesel different from the engine under the hood of most cars and light
trucks in the
Without resorting to a lot of tech-talk or a
lengthy and possibly boring statement, it will suffice to say the diesel
gets power faster without an electric sparkplug – it uses compression
to ignite the fuel – and, thus, does not require a fuel with a high
ignite or combustion factor. Admittedly, that is over-simplification, but
when reviewed by a Mercedes-Benz person I was reassured, “That is
accurate.” In fact, diesel engines are so flexible they can run on
vegetable oil. If you don’t believe me, check out this video
featuring movie diva Daryl Hannah who only drives biodiesel. For those who want a more
comprehensive and understandable explanation and demonstration visit www.howthingswork.com or click here for a
complete demonstration of how diesel engines work.
Generally, diesel engines are more effective,
efficient, economical and, eventually, environmentally acceptable than the
more familiar internal combustion engine. They get 20 to 30 percent better
fuel economy, which results in roughly a 20 to 30 percent reduction in the
emissions of carbon monoxide (CO), carbon dioxide (C02) and hydrocarbon
gases.
Why all the news, information
and conversation about diesels now?
Many factors, facts and fallacies have
contributed to diesel news: among them –the global warming
phenomenon; state emissions controls and regulations; the soaring cost of
oil per barrel and, subsequently, gas per gallon; lingering perceptions of
diesel engines; more vehicles on the road; the depletion of natural
resources; governmental action or inaction; court cases, including the U.S.
Supreme Court case that opened this week, and Al Gore’s
notwithstanding environmental concern.
In the U.S., stringent new regulations
concerning the sulfur emissions – cleaner burning – from
diesels in heavy trucks (when you’re behind an 18 wheeler with a
heavy load at a stop light, a gas mask is a welcome accessory) resulted in
a drastically lower sulfur composition in the formulization. These big
trucks may be a reason why many equate the technology with older cars and
light trucks powered by diesel engines – noisy, smelly, etc. Another
factor has been the limited availability of diesel fuel at service
stations. But this is also about to change.

Last month, 45,000 service stations in 45 states
began selling the “new and improved, ultra low sulfur” diesel
fuel in response to the government’s request for lower exhaust gas
emissions. Not all stations have the new fuel and it will be
“sometime” before the new fuel replaces the old, according to
one source I spoke with.
The national average price of the new diesel
fuel as this article is being written, according to the Energy Information
Administration, stands at $2.567 per gallon compared to regular gasoline,
which averages $2.246 per gallon. In 2009 – just three short years
away – an even tougher, tighter fuel composition regulation will be
instituted.
Additionally and significantly, this new diesel
fuel formula has resulted in significant re-engineering for
“cleaner” diesel engine-equipped cars destined to be sold in
this country. Brands including VW and Volvo that sold diesel-equipped cars
have stopped selling in the

Who is leading the industry in
diesel innovations and technology?
Mercedes-Benz, the first car manufacturer to
produce a diesel-equipped passenger car over 70 years ago, is still the
highly motivated leader in diesel inventions, innovations, and
improvements.
The result of the company’s significant
investments in time, people and resources appeared earlier this year at the
North American International Automobile Show with the introduction of the
BLUETEC diesel line. To borrow a phrase, “these are not your
father’s diesels!”
A media release stated, “Mercedes-Benz is
the pioneer of a new generation of clean and powerful high-tech vehicle s
with highly effective exhaust gas treatment systems that give them the
potential to fulfill the most stringent emission limits in the
future.” And they are turbo powered too.

Mercedes-Benz lineup of Bluetec diesels |
Last month, Mercedes-Benz unveiled its new E320
Bluetec sedan. It accelerates from 0 to 60 in just 6.6 seconds thanks to
400 pounds of torque and earns a significant 37 mpg highway/26mpg city. The
E series will be joined by four other new-Bluetech diesel-powered vehicles
next year as well.
The new 2007 models are not just fully compliant
with new regulations, they set the benchmark for diesel engine technology
that others will most definitely strive to emulate.
On the eve of the Los Angeles Motor Show
DaimlerChrysler, Audi and Volkswagen announced that they intend to
establish the BLUETEC brand name as the designation for particularly clean,
highly fuel-efficient passenger cars and SUVs with diesel engines. Under
the shared concept of BLUETEC, each of the manufacturers involved will be
working on their own technical systems for meeting the world’s most
stringent emission regulations.

A peek under the hood at Audi’s diesel technology |
Recently, Audi premiered a world first
twelve-cylinder diesel engine in a passenger car, the Q7. It is a
six-liter, V12 generating, 500 horsepower and 738 ft-lbs of torque beast
that is reminiscent of the engine featured in the winning Audi race car.
Fast? 0 to 62 in 5.5 seconds with an electronically governed top end of 155
mph. Wow! Too bad it won’t be sold here … yet.
Honda’s on the
Diesel-powered Bandwagon
John Mendel, senior vice president for American
Honda Motor, noted confidence this summer when he said, “Our diesel
technology will achieve our goal of crating new value in the market. Some
have suggested this will be as important a breakthrough as the Civic CVCC
was in being the first to meet the U.S. Clean Air Act in the early
1970’s.”
Mendel’s comments were followed late
September by a release from Honda headquarters in

What’s Up In
GM has been quiet about plans for its diesel
engines, but announcements should be made soon. You can bet the Chrysler,
Dodge and Jeep brands will be among the first to establish a foothold with
technology from its European divisions. And Ford has recently announced the
development of a new regulation-compliant diesel engine.
Diesels bottom line?
Like the old movie title, The
Diesels Are Coming. So, get ready. After years of literally ignoring
diesel-powered vehicles, Americans will soon see more and more diesel cars
and subsequently have the opportunity of benefiting from them.
The investment of countless millions of dollars,
euros and yen from auto manufacturers throughout the world has resulted in
a new generation of improved diesel engines … they’re
stealth-like silent, efficient, environmentally equitable, and, of course,
meet all the new government regulations.
