Is straight 6 better than V6?
Inline-Six Engine Design
It is also more expensive, which has contributed to its replacement by the V6 in many car manufacturing companies. Nonetheless, the inline-six is a stronger and more reliable engine than the V6. It is used in vehicles that are designed for longevity and towing.
Is V8 better than inline 6?
This is due to the fact that V-6 engines have two fewer cylinders. V-6 engines have improved performance compared to V-8 engines, especially when timing acceleration properly because there’s less tendency to drift to the outer edge. However, you can lose a little bit of the power ceiling with the weight advantage.

Why is an inline 6 so good?
Inline-sixes are also less complicated than other layouts. That means half the camshafts and half the cylinder heads of a V-6, which means less weight and fewer parts—a benefit that decreases cost and makes for fewer things to break after years of running.
Why are inline 6 engines so smooth?
As pistons 1 and 6 reach top dead Centre, the other four pistons are evenly spaced at 120 degrees and 240 degrees respectively around the engine cycle, meaning that the reciprocating forces balance each other out. This makes a smooth-revving engine for which units like the S50 and RB26 have become famous.
How much horsepower does a inline 6 have?
With a 230-cubic-inch inline six with a mild cam, headers, and the cylinder head work we’ve described, you could expect to make around 250 to perhaps 260 horsepower. Because the inline six crankshaft is so long, even with 7 main bearings it’s probably not a good idea to spin these engines much beyond 6,000 rpm.
