Overall Observations
At a time when most automakers are dropping their 4-door sedan
models, cars like the new Kia K5 prove there’s a lot of life left in this
erstwhile mainstream segment.
The midsize K5, an updated version of the company’s long-running
Optima sedan, gets a stylishly redesigned exterior with a longer,
lower look that makes it a sedan you’d actually like to be seen in. The
passenger cabin is equally well done and is roomy enough for 4 adults
to share the space in comfort.
The K5 is also a strong value proposition, with a long list of
desirable standard features including, in our test vehicle, bright
LED headlights, heated and ventilated front seats, and an easyto-
use infotainment system with Apple CarPlay and Android Auto
smartphone connectivity.
Our test car came equipped with a 1.6-liter turbocharged
4-cylinder engine (180 hp) that trades just-adequate acceleration for
good fuel economy. By contrast, the performance-oriented GT version
with its 2.5-liter turbocharged 4-cylinder engine (290 hp) delivers all
the power most people could ever want.
Figure in an impressive 5-year/60,000-mile factory warranty and a
full complement of advanced safety features, and the Kia K5 becomes
an attractive, practical, value-oriented choice.
