The second generation Optima, known as the Kia Magentis globally except in United States and Malaysia, and as the Kia Lotze in South Korea, was launched in South Korea in November 2005.
This generation differed further from the Hyundai Sonata donor vehicle than the previous model.
Unlike the previous Optima though, this vehicle uses a global platform, unique to Kia, designated "MG".
The car continues to be built in South Korea and shares its 2.4-liter inline-four engine, five-speed Sportmatic automatic or five-speed manual transmission with the Sonata.

The second generation Kia Optima was launched in Malaysia on 15 August 2007 powered by a 2.0 liter Theta DOHC CVVT engine with a 4-speed automatic transmission.
