"Subaru is one of the last automakers to still make a six-cylinder engine available in their midsize sedan. But, if the subsidiary of Fuji Heavy Industries follows the downsizing trend, the 3.6L boxer six-cylinder could be replaced by a smaller turbocharged four-pot."
What about the V6 in the Accord, Altima, or the Camry. Yes they aren't that many, but still a few...
“Our research said the six-cylinder model is decreasing in the world,” Hori said. “So that’s why probably the future, many companies take the smaller displacement with a turbocharger, or diesel, or hybrid.”
Hope you didn't pay too much for that research, pretty obvious by just watching the competition...
