The chassis was based on the one used on the MG K3 but was narrower and used N-type axles.<ref name="AZ1930" /> The engine used the cylinder block from the P-type but with a special crankshaft to bring the capacity down to 746 cc by reducing the stroke from {{convert|83|mm|in|1|abbr=on}} to {{convert|71|mm|in|1|abbr=on}}.<ref name=Magic/> A high-pressure Zoller supercharger was fitted giving a boost to 2.5 atmospheres (1.8 kg/cc) and allowing the engine to produce {{convert|113|bhp|abbr=on}} at 7200 rpm.<ref name="Magic" /> A sprint version was also made with output increased to {{convert|146|bhp|abbr=on}} which at nearly {{convert|200|bhp|abbr=on}} per litre was the highest specific output of any engine in the world at the time <ref name="Beaulieu" >{{cite book |last=Georgano |first=N. |authorlink=G.N.
