DCVCP
A variant of 1.8L Family 1 engine featuring Euro IV compliancy, DCVCP (Double Continuous Variable Cam Phasing technology, a variant of VVT) and integrated catalytic converter, entered production in Spring 2005. It was based on the lighter cast-iron block, although there's no TwinPort in this version.
An updated 1.6 L TwinPort engine with DCVCP was introduced in 2006.
In 2011, the new Gen III block has been introduced which features DCVCP, TwinPort and piston cooling by oil jets, as well as higher compression ratio.
These engines are manufactured at Szentgotthárd, Hungary, Bupyeoung, Korea and Toluca, Mexico.
