E-type and OE-type
Production of the 30/98 restarted in 1919 as the E-type. The engine was carried in a separate subframe on the ladder type chassis with semi-elliptic leaf springs front and rear. The car could be supplied as a chassis for completion by external coachbuilders or with the factory built Velox four-seat open body. 274 were made.
In 1923 the engine was updated and fitted with overhead valves and detachable cylinder head and became the OE-type with a capacity of 4224 cc and power output of 115 bhp (86 kW) at 3300 rpm. From late 1923 front wheel brakes became available, at first cable operated but hydraulic from 1926. 313 were made.
The last cars were made in 1927 and these had a final engine improvement with balanced crankshaft allowing them to be tuned to 120 bhp (89 kW) and a closer ratio gearbox.
