I engines are cheaper to build, produce better efficiency rates, and are simpler from a mechanical standpoint. ... Because of the way they merge, V-shaped engines can fit more pistons into a smaller space, produce more torque at lower RPMs, and generally have greater engine displacement.

Why are V engines better?

V-type engines (V) sit lower with an improved center of gravity, and this design is more space-efficient with a greater numbers of cylinders. Horizontally opposed engines (H) sit very low and wide, producing a low center of gravity and improved handling.

Which is better V or W engine?

The W-engine happens to be an even better-reworked version of the compact V-shaped engines, this particular design means an even more compacted configuration. ... These are very rare as the V-type configuration caters almost to all the needs of compact engine construction.
