The Family 0 is a family of inline piston engines that was developed by Opel, at the time a subsidiary of General Motors. It was developed as a low-displacement engine for use on entry-level subcompact cars from Opel/Vauxhall.

These engines feature a light-weight cast-iron semi-closed deck engine block with an aluminum cylinder head. The valvetrain consists of chain-driven hollowcast dual overhead camshafts (DOHC) that actuate 4-valves per cylinder via roller finger followers with hydraulic tappets. These engines also feature a {{convert|78|mm|in|abbr=on}} bore spacing and fracture-split connecting rods.

Later versions also incorporate a variable length intake manifold (VLIM) and variable valve timing (VVT).

Originally debuting as either a {{convert|973|cc|L|1|disp=flip|abbr=on}} straight-3 or {{convert|1199|cc|L|1|disp=flip|abbr=on}} straight-4; a {{convert|1364|cc|L|1|disp=flip|abbr=on}} I4 variant was added with the introduction of the second generation, replacing the 1.4 L Family 1 engine. The Family 0 engines were produced by Opel Wien in Vienna/Aspern (Austria), by GM in Bupyeong (Korea) and Flint (Michigan, USA).

Generation I {{anchor|X10XE|Z10XE|X12XE|Z12XE}}

The engine was first introduced in the 1996 Opel Corsa, either as a three-cylinder or as a four-cylinder version. This was Opel's first three-cylinder engine.

Generation II{{Anchor|Z10XEP|Z12XEP|Z14XEP|Twinport}}

The second generation Family 0 began production in November 2002. It is an updated version of the Family 0 engine and features TwinPort technology – twin intake ports with a choke closing one of the ports at low RPM, providing strong air swirl pattern for higher torque levels and better fuel economy. The crankshaft and oil galleries were also redesigned to lower power loss; thereby increasing fuel economy.

Generation III

The EcoFlex engine is a version of the TwinPort tuned to provide better fuel economy and lower emissions. The 1.4 L engine was introduced in 2008 and the 1.0 L engine in 2010. For model year 2012, the EcoFlex engines have been updated with double cam phasing (DCVCP) in a Gen III block.

Certain Opel and US-market Chevrolet versions of the Delta II platform compact cars use a turbocharged version of the 1.4 L engine with double variable cam phasing (DCVCP); in the future, an optional gasoline direct injection system will be introduced.{{cite web | url=http://mediaassets.gmeuropearchive.info/viewcatalogue.php?catid=108560&lng=EN|title = A Look Into the Future of Engines and Transmissions| author=General Motors Europe|date=May 2008|at= New 1.4 Turbo }}

Opel versions feature Start&Stop system from 2011 and a Gen III block; a lower-power 120 ps version has been introduced as well. For model year 2013, the overboost to {{convert|220|Nm|lbft|0|abbr=on}} has been added.{{cite web |url=http://media.opel.com/media/intl/en/opel/news.detail.html/content/Pages/news/intl/en/2012/opel/06_15_new-astra-family.html |title = Opel {{!}} Stellantis}}
