The Ecotec name was adopted in 2000 for the new generation of Family II engines. The name was already used for the Opel GM Family II engine, Family 1 and Family 0 ranges. GM intends this new Ecotec to become its global 4-cylinder.
The Ecotec Family II is a DOHC 4-valve design with an aluminum block and head (L850 for 86mm bore applications, and L880 for 88mm bore), designed for displacements from 1.8 to 2.4 L. It was developed by an international team of engineers and technicians from Opel's International Technical Development Center in Rüsselsheim, Germany, GM Powertrain in Pontiac, Michigan, and Saab in Trollhättan, Sweden.[citation needed] Much of the development work on this project was carried out by Lotus Engineering, Hethel, United Kingdom. The engine uses aluminum pistons and cast iron cylinder liners. Vibration is reduced with twin balance shafts.
Holden makes various Family II engines for GM India and GM Daewoo at its Melbourne plant. Variations include displacements from 1.6 L. to 2.4 L. Unlike the Ecotec engines, the block is made of iron.
