the alfa romeo se 048sp was a group c racing car built by alfa romeo in the early 1990s. designed to replace the lancia lc2 after the group c regulations had undergone a major revamp, the se 048sp had an abarth-developed chassis mated to the 3.5-litre v10 engine from the stillborn alfa romeo 164 procar, but, although at least one se 048sp was built, it never left the development phase. the v10 engine appears to have been replaced by a ferrari-sourced 3.5-litre v12 engine at some point during its development, although this was never officially confirmed by alfa romeo.
