1915 Mercer 22-70 Raceabout

In the autumn of 1914, the Mercer Automobile Company announced a new series of cars designated the 22-70, including a Raceabout and Runabout on a 115-inch wheelbase. The design of these cars was a departure in all regards from the type 35 T-head they replaced. The new L-head motor of 298 cubic inches was adopted from that of the Deltal racing car which finished second to Mercer at Elgin in 1913. The Deltal race car was designed and built by Erick Delling and a colleague named Hackenthal (thus the name Deltal). Delling was employed as Chief Engineer by Mercer until late 1915 and was responsible for the designs of the 22-70.
