In [[automotive engineering]], a '''longitudinal engine''' is an [[internal combustion engine]] in which the [[crankshaft]] is oriented along the long axis of the [[vehicle]], front to back.

Most "premium" vehicles use this engine orientation, both front and [[rear wheel drive]]n, due to the fact that powerful engines such as the Inline-6 and 90° big-bore V8 are usually too long to fit in a FF transverse engine while most mainstream modern vehicles use [[front wheel drive]] along with [[transverse engine]] arrangement

==Position placement of longitudinal engines==
Engines may be placed in three main positions within the motor car:
* [[front-engine design|front engine]] - where the engine is mounted under the bonnet/hood, over the front axle (sometimes ahead of the front axle, sometimes behind it: "mid-front" engine),
* [[rear-engine design|rear engine]] - where the engine is mounted where the boot/trunk would normally be, either over, or to the rear of the rear axle,
* [[mid-engine design|mid engine]] - where the engine is mounted between the front and rear axles, usually where the rear seats would be sited.

==Common types of longitudinally placed engines==
This is a list of typical examples of types of engines which can be placed in motor vehicles:
* [[straight engine|in-line or straight engine]] - where [[straight-two|two]], [[straight-3|three]], [[straight-4|four]], [[straight-5|five]], [[straight-6|six]], and even [[straight-8|eight]] cylinders are placed in a single plane,
* [[V engine]] - where [[V-twin|two]], [[V4 engine|four]], [[V6 engine|six]], [[V8 engine|eight]], [[V10 engine|ten]], [[V12 engine|twelve]], or even [[V16 engine|sixteen]] cylinders are placed in two separate planes, looking like a "V" when viewed from the end of the crankshaft,
* [[flat engine|flat or boxer engine]] - where [[flat-twin|two]], [[flat-4|four]], [[flat-6|six]] or more cylinders are arranged in two diametrically horizontally opposed planes,
* [[W engine]] - where two (narrow angle) vee engines are siamesed together (within 180°), where at [[W8 engine|eight]], [[W12 engine|twelve]] or [[W16 engine|sixteen]] cylinders are arranged in four separate planes,
