Improved Performance

While the Kia Optima was certainly no slouch when it came time to performance, the 2021 K5 has been specifically engineered to make spending time behind the wheel a real thrill.

The Optima’s top performing 2.0-liter turbo engine delivered an impressive 260 lb-ft of torque and had an output of 245 horsepower. In contrast, the all-new Kia K5’s powerful 2.5-liter turbo engine is capable of producing as much as 311 lb-ft of torque and up to 290 horsepower. Those are top performance levels in its class!

Additionally, the 2021 K5 GT can accelerate from 0-60 mph in less than six seconds, marking a full second of improvement over the Optima’s best.

Advances in Safety Tech

The retired 2020 Kia Optima had a very safe design that was recognized with a 5-star safety rating from the National Highway Traffic Safety Administration. Given that the K5 is based upon the Optima’s architecture, it is no surprise that the NHTSA has also given the sedan a 5-star overall rating.

The 2021 K5 comes with significant standard safety technologies like automatic emergency braking and lane-departure warning that make it a reliable pick for families.

Updated Design

One of the most obvious improvements the 2021 Kia K5 makes over its predecessor, the Optima, is in terms of appearance. While the vehicles have a similar overall profile, the Kia K5 has a more aggressive front fascia and a streamlined tail. Bold LED headlights, sculpted body moldings, and athletic new wheel options drive home just how different the K5 is from the Optima.
