kia k4 ex sedan 2027

The 2027 Kia K4 EX Sedan represents a notable evolution of Kia’s compact sedan, bringing meaningful upgrades in engine performance, interior space, efficiency, and tech over the 2026 model. Thanks to refinements to the body and powertrain, the 2027 EX pushes the K4 further toward a near-mid-size feel without losing its compact-class benefits.

Engine & Performance:
The EX sedan’s standard powerplant shifts to a 2.0-liter SmartStream inline-4 producing around 190 hp and 181 lb-ft of torque, a clear boost in performance over the prior base engine. An 8-speed automatic transmission replaces the previous CVT, improving responsiveness and refinement and helping the car achieve a 0–60 mph time in the mid-7-second range. Top speed increases to about 134 mph with the new setup. The 2027 EX sedan’s larger footprint—especially the stretched wheelbase (~112.4 in)—results in more interior room and rear legroom compared with 2026 models. Exterior dimensions also grow slightly to deliver improved presence and aerodynamic performance. Despite the performance boost, improved engine calibration and updated transmissions help maintain competitive fuel economy figures—around 31 mpg city and 42 mpg highway—with a larger fuel tank for extended range.
