+The '''C20NE''' is a [[Family II]] fuel injected, four cylinder engine developed by [[General Motors]] in the late 80's.  It is essentially very similar to the [[C20XE]], but has a simpler cylinder head design which features 2 valves per cylinder (rather than the four of the [[C20XE]]) and single overhead camshaft.  For this reason, the powerplant is commonly referred to as '8 Valve'.  The C20NE was factory fitted to early [[Opel Astra]] and [[Vauxhall Cavalier]] models, but also found its way into the entry spec [[Calibra]].  Subsequently, the fitment of the C20NE engine permitted the use of an automatic transmission, particularly in the [[Calibra]] where the [[C20XE]] developed excessive amounts of power and torque for the automatic box.  Although lacking the power of its bigger siblings, the C20NE has proven to be an economical and robust engine, with many examples still running flawlessly today.

-[[General Motors Corporation|General Motors]]' [[Opel]] division in Europe designed a compact [[V6]] engine with an odd 54° vee angle. It was an iron block/aluminum head [[DOHC]] design with 4 valves per cylinder. All 54° engines are assembled at [[Ellesmere Port]] in [[England]].
-This engine was used in the American versions of these models as well. The engine was reworked substantially between the 3.0&nbsp;L L81 and 3.2&nbsp;L LA3, but the bore centers and deck height were retained.  In its 3.0 L form, this engine has a notable history for recalls of all units installed in U.S. Cadillac Cateras due to problems with timing belt tensioner bearing failures, which could cause catatrophic damage to the engine with its interference design.

-The '''L81''' was used [[longitudinal engine|longitudinal]]ly in the [[Opel Omega]], [[Cadillac Catera]] and [[transverse engine|transverse]]ly in the [[Saturn L-Series]], [[Saturn Vue]] and [[Saab 9000]]. Bore and stroke were 86&nbsp;mm (3.38&nbsp;in) × 85&nbsp;mm (3.35&nbsp;in), for 2962&nbsp;cc (180.75&nbsp;cu&nbsp;in) displacement. with 10.8:1 compression, the engine produced between {{Convert|182|hp|kW|0|abbr=on}} and {{Convert|208|hp|kW|0|abbr=on}} with {{auto ftlbf|190}} to {{auto ftlbf|199}}.

-The 3.2&nbsp;L '''LA3''' is a complete redesign of the L81 for the [[Cadillac CTS]] and [[Opel Omega]] B. It had an iron block and used aluminum [[DOHC]] heads with fixed (non-variable) valve timing, and a [[VLIM|variable intake]]. The bore was 87.5&nbsp;mm and it had an {{Auto mm|88|1}} stroke. This was a 3175cc (194&nbsp;cu&nbsp;in) engine and produced {{Convert|220|hp|kW|0|abbr=on}} and {{auto ftlbf|218}}. Production started in July 2001, but the engine was replaced by the new [[GM High Feature engine]] starting in 2004.
