Due to the short length of flat engines, locating a flat engine outside of the car's [[wheelbase]] results in minimal overhang.<ref>{{Cite book |last= Nunney|first= M.

Examples include the flat-twin [[BMW 600]] (1957–1959) and [[BMW 700]] (1959–1965); the flat-four [[Tatra 97]] (1936–1939), [[Volkswagen Beetle]] (1938–2003) and [[Porsche 356]] (1948–1965); and the flat-six [[Chevrolet Corvair]] (1959–1969), [[Porsche 911]] (1963-present), and [[Tucker 48]] (1947–1948).

The opposite layout, [[front-engine, front-wheel-drive layout|front-engine front-wheel drive]], was also common for cars with flat engines. Examples include the [[Citroën 2CV]] (1948–1990), [[Panhard Dyna X]] (1948–1954), [[Lancia Flavia]] (1961–1970), [[Citroën GS]] (1970–1986), [[Alfa Romeo Alfasud]] (1971–1989) and [[Subaru Leone]] (1971–1994).

Subaru have been producing cars with a [[front-engine, four-wheel-drive layout]] powered by flat engines (mostly boxer-four engines) since 1971. Examples include the [[Subaru Leone]] (1971–1994), [[Subaru Legacy]] (1989-present) and [[Subaru Impreza]] (1992–present). The front half-shafts come out of a front differential that is part of the gearbox. A rear driveshaft connects the gearbox to the rear half-shafts.

The traditional [[front-engine, rear-wheel-drive layout]] is relatively uncommon for cars with flat engines, however some examples include the [[Toyota 86|Toyota 86 / Subaru BRZ]] (2012–present), [[Jowett Javelin]] (1947–1953), [[Glas Isar]] (1958–1965) and the [[Tatra 11]] (1923–1927).
