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.
