Many of the most-iconic sports cars ever made featured six-cylinder engines, with more-recent models heavily favoring the V-format over in-lines. But even though V-6 engines currently are more popular than straight-six engines, there are plenty of pros and cons to both layouts.

With V-6 engines, for example, their V-configuration makes them more condensed, which is good for packaging. But the arrangement also means manufacturers have to compensate for their inherent unbalanced nature.

A recent video posted by Car Throttle touches on this, and many more differences between the two popular engine formats.

As this video noted, straight-six engines could be making a comeback, which is great news.

Although some manufacturers, such as Volvo and Porsche, have started replacing their six-cylinder units with new in-line fours that are lighter and more-powerful, which is even better news.
