A larger V6 engine tops a short list of 2002 changes to Kia's compact sedan. Optima is based on the Hyundai Sonata produced by Kia's South Korean corporate parent. Optima uses Sonata's 4-cyl and V6 engines and comes in LX and SE models. The V6 grows to 2.7 liters from 2.5 liters for a gain of 8 hp. The 4 cyl teams with manual or automatic transmission, the V6 with automatic only--V6 Optimas have a separate gate for manual shifting. Front side airbags are standard. ABS is optional with the V6, though Optima doesn't offer Sonata's available traction control. V6 Optimas have rear disc brakes in place of drums. Optional leather upholstery is available on SE models and this year includes a power front passenger seat. In other '02 changes, 15-inch wheels replace 14s as standard, and SEs gain standard automatic headlights. Optima's performance and accommodations mirror those of like-equipped Sonatas.
