The 20NE is a fuel-injected, four cylinder engine developed by General Motors.

This was the first overhead cam (OHC) engine from Opel, featuring milestone technologies like:

• Aluminum head.
• Cross flow design
• Multi point fuel injection
• Electronic ignition/fuel injection.
• Over Head Cam

This was "the" beginning of all the later Opel petrol engines. This was the first time the cast iron block found in most newer 2 liter Opel engines was featured.
