Engine Displacement Charts
 

Engine displacement is calculated by the formula bore x bore x stroke x .0031416. Bore is your piston size and stroke is your crankshaft size. VW would round engines sizes up to the next 100cm mark, so both the 1131cc 25hp and 1192cc 36hp (and the 1192cc 40hp for that matter) were referred to as 1200cc engines, 1285cc was 1300cc, 1493cc was 1500cc, and 1585cc was 1600cc. Aftermarket sizes are more exact. Original stock sizes are highlighted in blue.
