The vehicles we drive are powered by many engine types (and electric motors, of course) — but perhaps two of the most emotive forms of internal combustion engine are the V and flat configurations.

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

Flat engines are horizontally-opposed piston engines, and this group includes Boxer engines, but not opposed-piston engines like the Cummins 14.3L Advanced Combat Engine (ACE) designed to power tanks.
