In the United States, the Subaru brand is best known for all-wheel drive, but the automaker also touts its horizontally opposed engines as a key benefit. All of its vehicles (except for the new EVs) are equipped with flat-fours, which have a lower center of gravity and better balance than the inline-fours that are far more common in its competitors. But the automaker has experimented with flat-six engines in the past as a means to improve power (and prestige) in its cars, most recently in the 2019 Subaru Outback 3.6R.
