The 2005 KIA Optima is a mid-size sedan that marked a significant step forward for the Korean automaker in the North American market. This generation of Optima, internally known as the "MS" platform, was a departure from its predecessor, offering a more refined and spacious interior with modern styling that aimed to capture the attention of a broader audience. The Optima was available in a variety of trim levels, ranging from the base LX to the more luxurious EX and SX models. Power came from a choice of two four-cylinder engines: a 2.4-liter unit producing 162 horsepower or a 2.7-liter V6 developing 173 horsepower. Both engines were mated to a four-speed automatic transmission, providing a smooth and reliable driving experience. While the 2005 Optima was praised for its comfortable ride and well-appointed cabin, it was also recognized for its safety features. Standard safety equipment included anti-lock brakes (ABS), front airbags, and a driver's side knee airbag. The Optima's design and construction also contributed to its overall safety performance, earning a four-star safety rating from the National Highway Traffic Safety Administration (NHTSA). The 2005 KIA Optima offered a compelling combination of value, practicality, and reliability, making it a popular choice for families and individuals looking for a comfortable and well-equipped mid-size sedan. The factory service repair manual provides valuable information for both owners and mechanics, serving as a comprehensive guide for maintaining and repairing this vehicle.
