on slow death of the V6 engine in mainstream vehicles. With new
CAFE regulations pushing for increased fuel economy -- to the
tune of a fleetwide 35.5 mpg average -- many manufacturers are
turning to direct injected four-cylinder engines and turbocharged
four-cylinder engineer to increase fuel economy.
it's not just the government that is shoving higher fuel economy down
the throats of auto manufacturers -- the buying public is also moving
en masse towards four cylinder engines. According to Edmunds,
percent of midsize sedans sold in the United States (think Camry,
Accord, Altima, Malibu, Fusion, etc.) come with a four-cylinder
engine despite the fact that vastly more powerful V6 engines are
available on the options sheet.
that a number of factors have resulted in V6 and V8 engines seeing a
sharp decline for 2009. Wards
cites that consumers have less money to spend these days, so more
fuel efficient four-cylinder engines which get better fuel economy
are being chosen. In addition, a sharp reduction in the production of
light trucks has contributed to the downfall of engines with six or
states that four-cylinder engines accounted for 61.9 percent of new
car sales for 2009 -- this compares to just 51.7 percent in 2008.
Whereas V8 engines were found in 88.9 percent of new cars sold way
back in 1969, that figure is just under five percent today.
sectors that are showing gains are diesel engines (3.7 percent market share), turbocharged engines (2.9 percent market share), and hybrid powertrains (2.4 percent market share).
like the new industry darling Hyundai are dropping V6 engines
entirely from its midsize sedan offerings. The new 2011 Hyundai
Sonata can currently only be had with a direct injected 2.4-liter
four cylinder engine (paired with a 6-speed stick or 6-speed
automatic) which produces 198 hp and get 35 mpg on the highway. Later
this year, Hyundai will also introduce a turbocharged inline-four
engine which will closely match the 35 mpg of its naturally aspirated
counterpart while at the same time delivering power comparable to the
3.5-liter to 3.6 liter V6 engines offered in vehicles like the Toyota
Camry and Chevrolet Malibu.
also plans to release a four-cylinder
hybrid variant of the Sonata before the end of the year to
complete the four-cylinder trifecta.
