Besides the initial 2-litre engine, the E01 engine can also be configured to spawn 1.8-litre and 2.2-litre variants.
When the E01 engine was developed by Petronas, the engine was designed to meet the Euro 2 emission standard.
As a result, Proton is currently reworking the engine, in addition to the development of
an all-new family of six engines, to meet the upcoming Euro 6C standard.

. It was the first commercial automotive engine in Malaysia. The development of the engine started in March 1997, with the engine start-up ceremony being held on 20 February 1998.
The engine was intended to be supplied to Proton; however, Proton had ultimately opted for their self-designed

After the first failed attempt to sell the engine patents to Proton, Petronas was looking for other carmakers who were willing to buy the engine patents. In 2005, a Chinese carmaker
Nanjing Automobile
Nanjing Automobile is a state-owned enterprise with a history that dates from 1947, was interested to buy the engine patents. A letter of intent was signed on 2 September 2005.
Nanjing Automobile also had set up a plan to mass-produce the E01 engine;
however, the plan did not materialize at all.
It was not until 2006 that Proton intended to take over the patents of the E01 engine. A memorandum of intention was signed by both parties on 29 January 2006.
However, the patent purchase was only finalized in 2012, as Petronas decided to exit from all engine development activities since 2010.
The engine patent purchase provided Proton with an immediate ownership of a family of powertrains consisting 2.0-litre and 2.2-litre engines in

With the patents of the E01 engine being acquired from Petronas, the E01 engine becomes one of the two upcoming engine families to succeed the CamPro engine which was in service since 2004 via the
