10 Things You Should Know About the 2011 Hyundai Sonata
Hyundai’s midsize sedan aims for the best in the class.
#5. Fuel economy is impressive.
In developing the 2011 Sonata, Hyundai made several changes that all
add up to impressive fuel economy. Aside from the powertrain changes,
the engineers made sure the car was light and aerodynamic. A lighter,
stiffer body structure helped cut 54 pounds out of the curb weight,
while the new exterior design and a smooth underbody cut the
coefficient of drag from 0.32 to 0.28. Low-rolling resistance tires, a
low-friction driveline, and a smart alternator that charges only during
coasting also add incrementally to fuel economy. The result is a car
with class-leading EPA fuel economy ratings of EPA 24 mpg city/35 mpg
highway with the manual transmission and 22/35 with the automatic.
