It was a high-performance development of the BMW M78 engine that was produced alongside the M78.[1] Compared with the M78, the M328 has an aluminium cross-flow cylinder head[2] with hemispherical combustion chambers.[3] The M328 was used in the BMW 328 and BMW 327/28 coupes.[4] After World War II the engine was also licensed to Bristol Cars in the United Kingdom. DesignThe M328 had an unusual valvetrain design; although the camshaft is located in the engine block, the exhaust valves are actuated by a transverse pushrod from the intake valves.[3] This results in a valve layout similar to a DOHC engine. With a bore of {{convert|66|mm|in|2|abbr=on}} and a stroke of {{convert|96|mm|in|2|abbr=on}}, the displacement was {{convert|1971|cc|cuin|1|abbr=on}}, the same as its M78 predecessor. Fuel supply was via three Solex "30 JF downdraft" carburetors.[3] The M328 engine has a compression ratio of 7.5:1 and produces {{convert|59|kW|bhp|0|abbr=on}} at 5000 rpm.[3][5] Versions
