 The Energy engine has also equipped the Renault 9 in Argentina, Colombia and Turkey.However, at the launch of the Renault Twingo in 1993, Renault would be forced to continue production of the Cléon-Fonte engine because the "E engine", due to its hemispherical cylinder head and front exhaust, was too large to accommodate in the Twingo.The Energy (E7F) was gradually replaced with the D7F engine in 1996 on the Renault Clio, due to new standards of pollution control and lower fuel consumption required for more modern engines.
