Decade Trend Shows Engines Getting Smaller for Mainstream but More Power for Performance Enthusiasts

A recent SEMA eNews report says that more stringent fuel
economy and emissions requirements have shifted engines toward smaller displacement options. Sales of four-cylinder engines grew from 2006 to 2007 while
larger displacement eight-cylinder sales shrank.

Six-cylinder engines, however, remain largely unchanged, a shift
more noticeable as more powerful compact engines replace outdated
larger ones throughout the entire range. Considering the market shares
of vehicles sold in 2008, the scenario is likely to be even more

Compact vehicles are now beginning to erode the dominance of their
midsized counterparts as consumers look to smaller, lighter and
generally more affordable vehicles. Influence not only comes from
economic circumstances, but also from more contemporary offerings of
attractive technology in this segment. Engines are becoming more
powerful while improving efficiency.

The trend toward smaller engines has been noted in Ward’s 10 Best Engines competition, in which Ward’s
editors vote on the best contemporary engine designs, which includes 13
four-cylinder nominees – twice what it was 10 years ago. V8 engines nominated for this year’s award has been cut by more than half,
just four options versus nine choices a decade ago. Six-cylinder
options remain the largest eligible grouping.

For the magazine’s 2009 competition, there are eight forced
induction candidates, along with three hybrid systems and three
diesels, all meeting 50-state emissions requirements.

However, SEMA research shows that car enthusiasts prefer the more powerful V8s with a 36 percent rise in four years. While 4-cylinder engines dropped to nearly 16 percent. Six-cylinder options also declined 25.4

Of those that purchased new vehicles in 2004 the largest group was
six-cylinder engines. In contrast, the largest group for 2008 has been
eight-cylinder engines. Keep in mind that these values are for new
vehicles. In 2004, the largest group of vehicle purchases was for used
vehicles with eight-cylinder engines.

For more original SEMA market research, please visit car buyers might be turning to fuel-sipping four-cylinders and refined v6s, but performance enthusiasts still want a v8 in their new cars.
