That wasn't the only exciting news
for diesel enthusiasts from the German front this week.
Volkswagen, Germany's largest automaker, announced that it will be
debuting three new
BlueMotion vehicles at the Frankfurt Auto Show. BlueMotion
is Volkswagen's most fuel-efficient diesel platform.
Polo, and Passat will all get BlueMotion variants -- the U.S. will at least get a diesel version of the Golf, the other two models are still up in the air. The Polo will get an incredible 71.3 mpg
(U.S.) and emit a mere 87 g of CO2/km. This
emissions performance matches that of the Smart
ForTwo, but the noticeable difference is that you can seat five
in the Polo, versus the titular two in the ForTwo. This feat is
pulled off thanks to Volkswagen's new 1.2-liter TDI engine.
up, the Golf gets an also impressive 61.9 mpg and 99 g of CO2/km
emissions off a peppier 103 hp 1.6-liter TDI. The mid-sized
Passat rounds off the lineup with the same engine, but lower fuel
economy at 53.4 mpg and higher (but still low) emissions of 114 g of
Among the ways Volkswagen has fine-tuned
its diesel performance to sip fuel is its recalibration of these
engines and reductions to their idle speed. To further reduce
idle losses, it's vehicles include an automatic start-stop system,
low rolling resistance tires and reduced aerodynamic drag thanks to
lower front air dams and rocker panel extensions.
diesel vehicles aren't the perfect fuel economy solution, they're
certainly giving mild hybrids a run for their money (the hot 2010
Toyota Prius gets approximately
50 mpg according to the EPA and the 2010 Honda Insight, another
top selling hybrid, gets 41 mpg -- both vehicles can manage much
higher fuel economy under certain driving conditions). What
should be truly exciting is when the price of both technologies drops
enough that diesel-hybrids can reach the masses.

quote: The density of petroleum diesel is about 0.85 kg/l (7.09 lb/US gal), about 18% more than petrol (gasoline), which has a density of about 0.72 kg/l (6.01 lb/US gal). When burnt, diesel typically releases about 38.6 MJ/l (138,700 BTU/US gal), whereas gasoline releases 34.9 MJ/l (125,000 BTU/US gal), 10% less by energy density, but 45.41 MJ/kg and 48.47 MJ/kg, 6.7% more by specific energy. Diesel is generally simpler to refine from petroleum than gasoline. The price of diesel traditionally rises during colder months as demand for heating oil rises, which is refined in much the same way. Due to recent changes in fuel quality regulations, additional refining is required to remove sulfur which contributes to a sometimes higher cost. In many parts of the United States and throughout the United Kingdom and Australia diesel may be higher priced than petrol. Reasons for higher priced diesel include the shutdown of some refineries in the Gulf of Mexico, diversion of mass refining capacity to gasoline production, and a recent transfer to ULSD, which causes infrastructural complications.

quote: Not sure what the US Audi TDIs are (Q7 and A3).
quote: It is sold in the US and I sat in it at the NYC Auto show.
quote: Low CO2 is nice, but its not exactly the only thing that the EPA looks for. :o)
quote: We have more stringent diesel emissions standards than most of the rest of the world.
quote: the emissions requirements were deliberatly changed to prevent european and other imports competing with the american market.. so preserving the highly profitable
quote: Exactly what part of it being about limiting foreign competition didn't you understand?
quote: As far as I understand it it was the result of lobbying by the US car industry. Initially the US wanted to clean up the air and diesel engines were smokey polluting things. US raised air quality standards past the point that diesels could match. US car manufacturers stop developing them. French and German makes continue developing. Diesels start getting clean and very popular outside the US. US car manufacturers realise they can't compete immediately so they lobby for air quality standards that even good diesels can't match. That keeps out the Europeans.
quote: Because, congress and the EPA keeping dumping all these rules on diesels.
quote: it's not some "Commifornia conspiracy", give it a rest.
quote: They are the leader but most other states follow CARB standards.
quote: The Polo will get an incredible 71.3 mpg (U.S.)
quote: OK, just noticed that, but it still leaves the question of what test this was on, and how the EU and EPA milage tests compare?
quote: The Rabbit name plate is gone. VW U.S. gave up the silly idea that they could sell more Golfs by calling them Rabbit in the U.S.
quote: He also hinted that a 5-Series diesel may be coming next year as well.
quote: Huh? The 5-series has had diesel engines at least 20 years.
