Efficient, Powerful Engine
Available in two powerplants - a 2.4-liter four-cylinder or a 2.7-liter V6 engine - and two five-speed transmissions (manual with LX four-cylinder model only), the 2009 Kia Optima introduces a new engine under its hood. When redesigned as a 2006.5 model, the peppy four-cylinder engine delivered 161 horsepower, a 15-percent increase from the previous generation. For 2009, a more powerful 2.4-liter engine takes its place, producing an additional 13 horsepower. Optima's four-cylinder output increases to 175 horsepower and 169 lb-ft of torque. The available 2.7-liter V6 engine remains a carryover but output has increased to 190 horsepower and 184 lb-ft of torque. The V6 is mated to a five-speed, gated automatic transmission. All automatics feature Sportmaticв„ў clutchless shifting.
The introductions of Dual Continuously Variable Valve Timing (CVVT) and a Variable Intake System (VIS) further enhance Optima's new under-the-hood excitement. These added systems improve the vehicle's fuel economy without sacrificing power.
Built on a unibody frame, the front-wheel-drive Optima utilizes independent front and rear suspension systems. MacPherson struts are used in the front with a multi-link layout in the rear and are joined with coil springs and anti-roll bars (standard equipment on all models) to engage drivers with responsive handling and provide utmost comfort whether the road is smooth or less than ideal.
