Despite its structural weight liabilities, the single-tailed prototype set a speed record over a 100 km (60 mi) circuit on 1 April 1937 by reaching 517.84 km/h (322 mph),[4] taking the record away from France. Another record was obtained on 10 April 1937 when it achieved 475 km/h (295 mph) over 1,000 km (620 mi).[5] Piloted by Furio Niclot Doglio, the Ba.88 prototype had two 671 kW (900 hp) Isotta Fraschini K 14 engines.
