A 3.5 liter V6 would probably be used in a sports car or a light truck. A 6.2 liter V8 is almost certainly a 3&#x2F;4 or 1 ton truck.<p>For standard passenger cars, the norm is closer to 2 liters. European cars are considered &quot;economy&quot; cars and have much smaller engines because they weigh less.<p>Many Americans spend far more time in their cars than Europeans, and we generally have more space to park them, so we prefer bigger cars. Not nearly as big as they used to be, but still bigger than the rest of the world. Bigger cars need bigger engines, and we do lots of highway driving so performance is important too.
