Why Don’t Cars Use Inline8 Engines Anymore?

In this video, we dive deep into the history and engineering behind one of the most intriguing engine designs—the Inline8 (or Straight8) engine. Once popular in luxury cars during the early 20th century, the Inline8 offered smooth power delivery and torque. So, why don’t modern cars use these long engines anymore?

Join us as we explore:

The history and early popularity of the Inline8 in iconic brands like Buick, Packard, and Bugatti.
The downsides of the Inline8, including its large size, weight distribution issues, and complex construction.
How the V8 engine outshined the Inline8 with its compact design and better powertoweight ratio.
Why modern engineering favors smaller inline4 and inline6 engines for efficiency and performance.
Where you can still find Inline8 engines in action—classic car shows and restorations.
