the project itself was a well-kept secret, and very little was ever revealed about the car's specifications. one thing that alfa romeo did reveal was that it used the 3.5-litre tipo 1035 v10 engine from the still-born alfa romeo 164 procar; this was a naturally aspirated 72 degree v10 originally designed for the ligier formula one team, and produced a claimed output of at 13,300 rpm. it is believed that the car was built in 1990, as it had a much simpler rear wing than those found on cars built for the 1991 world sportscar championship season, but no official build date was given. momo's founder gianpiero moretti had apparently been in talks with alfa romeo about using the se 048sp, but these did not result in any deal being made. as a result, although at least one se 048sp was built, the car never left the development phase, and never raced. it ended up in alfa romeo's museo storico, but made a public appearance at the 2010 goodwood festival of speed, where it appeared to be fitted with a 3.5-litre ferrari v12 engine, producing a claimed output of at 12,750 rpm. this may have been because the v10 engine had proved fragile in the "abarth se047", which was a re-engined lancia lc2 used as a test-bed for the se 048sp project. the budget that the se 048sp would have used, in combination with the money used in lancia's wrc programme, were used instead on the alfa romeo 155 touring car programme, which saw alfa romeo win numerous national championships, most notably the deutsche tourenwagen meisterschaft in 1993, and the british touring car championship in 1994.
