The Stemme S12 features a cantilever wing, a T-tail, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy and a single retractable engine.[1]

The aircraft is made from composite material. Its 25 m (82.0 ft) span wing employs winglets. The standard engine available will be the 115 hp (86 kW) Rotax 914 F2/S1 four-stroke turbocharged powerplant driving a retractable, folding, variable-pitch propeller. It has glide ratio of 53:1.[1]
