By this point, you should know all about the excellent new turbocharged, direct-injection four-cylinder engine from Hyundai and, by extension, Kia. There are plenty of pixels gushing about the engine's power and efficiency when lodged in the nose of the 2011 Hyundai Sonata 2.0T, and judging from our time behind the wheel of the 2011 Kia Optima 2.0T, the engine is no less at home lighting up the tires of the newest sedan from Kia. Buyers looking for a four-door with a little more edge than the Honda Accord, Toyota Camry or even the embiggened Sonata will be happy to see that the newest interpretation of the Optima wears some seriously aggressive sheet metal outside to go with some of the best power and fuel-efficiency in the mid-sized sedan class.
Kia says that the Optima 2.0T was built to be the Sonata's more menacing cousin, and in addition to the sedan's brawny lines and 274-horsepower four-cylinder turbo, the company's engineers folded in a firmer suspension and reworked power steering system for a more athletic driving experience. The changes may not be enough for us to call the 2011 Optima 2.0T a sport sedan, but they do serve to give the vehicle a significantly different flavor compared to the 2011 Sonata.
