Subframe

For example, in an automobile with its powertrain contained in a subframe, forces generated by the engine and transmission can be sufficiently damped to prevent disturbing the passengers.

Modern vehicles use separate front and rear subframes to reduce overall weight and cost while maintaining structural integrity.

Additionally, subframes benefit production by allowing subassemblies to be created and later introduced to the main body shell on an automated line.

The 1961 Jaguar E-Type (XKE) used a tubular space frame–type front subframe to mount the engine, gearbox, and long bonnet/hood to a monocoque "tub" passenger compartment.

Several companies in the automotive aftermarket, including TyrolSport in the US and Spoon Sports in Japan, offer solutions for subframe misalignment and movement issues.
