The simpler design of the straight-six—fewer moving parts and more space around the engine block—generally makes it easier and potentially cheaper for amateur mechanics to maintain. Engineering and Application V6 - How it Works | SCIENCE GARAGE

While a straight-six has fewer parts (one head vs. two), manufacturers like Mercedes-Benz have reintroduced them partly to save costs by sharing production lines with four-cylinder engines.

The straight-six is widely regarded as the smoother engine because its firing order naturally balances reciprocating forces. This leads to a linear, vibration-free power delivery.

The primary difference between V6 and straight-six (inline-six) engines lies in their physical arrangement, which fundamentally dictates their balance, size, and manufacturing complexity. A aligns all six cylinders in a single row, whereas a V6 splits them into two banks of three, angled to form a "V" shape .
