Ensign's car for the new season, the N174, was much like the N173, but at the opening round of 1974 in Argentina, Opel discovered how little progress had really been made. He qualified 26th, again dead last, more than seven seconds slower than pole-sitter Ronnie Peterson and almost one and a half seconds slower than Guy Edwards, who qualified 25th. The handling of the car was so flawed that he chose to withdraw from the meeting. Shortly afterwards Opel quit the team.
