The '''GM Family Z engine''' is a [[turbocharged]] [[common rail]] [[diesel engine]] produced by [[General Motors Korea]] since 2010. It replaced [[List of VM Motori engines#RA 420 SOHC|VM Motori RA 420]] diesel engine in a number of GM applications, such as the diesel versions of vehicles sold as [[Chevrolet]] made for North America, [[Daewoo]] made for Korea, [[Opel]] made for Europe and [[Holden]] made for Australia.
The engine features [[chain drive]]n [[DOHC]] valvetrain with hydraulic tensioners, twin [[balance shaft]]s in the oil pump and electronically controlled [[variable-geometry turbocharger]]; the common rail system operates at pressures of up to {{cvt|1800|bar|psi}}, maximum in-cylinder pressure is {{cvt|180|bar|psi}}, improving on power and torque. Compression ratio is 16.5:1.
For 2012, compression ration is reduced to 16.3:1, and a new intake port increases air flow and swirl control, improving [[nitrogen oxide]] ({{NOx}}) emissions and performance.<ref>{{cite web|url=http://media.gm.com/media/us/en/gm/news.detail.html/content/Pages/news/in/en/2012/Jun/0627_General_Motors_India_Launches_All_New_Chevrolet_Cruze.html|archive-url=https://web.archive.org/web/20120630122304/http://media.gm.com/media/us/en/gm/news.detail.html/content/Pages/news/in/en/2012/Jun/0627_General_Motors_India_Launches_All_New_Chevrolet_Cruze.html|url-status=dead|archive-date=June 30, 2012|title=General Motors India Launches All-New Chevrolet Cruze|website=Media.gm.com|access-date=24 May 2018|date=27 June 2012}}</ref>
