Certainly one of Peter Schreyer’s best designs, the Kia Optima provides more than adequate performance from the 200-hp four-cylinder base engine. For sportier performance, check out the 274-hp turbocharged 2.0L engines. For those looking for a greener vehicle, the Hybrid version uses a 159-hp 2.4L gas engine teamed with a 46-hp electric motor. All powertrains use the six-speed automatic.
